1. Introduction

1.1 Scope of the Manual

This document describes the software features, on-site setup, and operation of the Cordex System Con­troller (CXC) from Alpha Technologies. A basic understanding of Ethernet, TCP/IP, SNMP, RS-485, and
CAN bus functionality is required.

Refer to the Installation manual for hardware details.

1.2 Software Overview

The CXC software enables control of an entire DC + AC power system via the CXC central touch screen
user interface or web based monitoring and control interface. The software also allows the user to control
temperature compensation, auto equalization, remote access, and battery diagnostics.

The CXC is an integrated Alpha Cordex Controller designed to provide universal control for Alpha Group
products.

The CXC has Ethernet capability that supports a web interface and SNMP for customer access to the
equipment it is monitoring.

The CXC also has a CAN bus for communication with the Cordex rectifiers and other peripheral equip­ment.

1. 2.1 User Interface (UI)

Version 3.1x of the software is compatible with Expanded Memory CXC Controllers only. For each con­troller, a user can use either a touch screen or a web interface to set up and manage the system.

Remote communications over the web interface can be established with the step-by-step connection
wizard available from the Alpha website (www.alpha.ca.ca) or refer to Chapter “9. Remote Communica­tions” on page 104 for detailed instructions.

1. 2.1.1 LED lights

Each CXC has three LEDs located on the front panel. These LEDs are used to display the alarm status of
the power system, CXC progress and status during startup, and file transfers.

1.2.1.2 Alarm conditions

When an alarm occurs, an LED illuminates corresponding to the following system alarm status:

• Green – OK, no alarms present.

• Yellow – Minor alarm is present (no major alarms).

• Red – Major alarm is present.

Only one LED is illuminated at a time during alarm conditions.

0700015-J0 Rev B

2. Standard Features

The following are new features in Version 3.1x:

• Retrieve inverter history file—see 6.4.8.2)

• Inverter alarms reported in the Event log—see 6.4.8.1

• Synchronization of the real time clock of the inverter controller (T2S) with the Cordex controller RTC

• Support of new CXCi+ hardware

2.1 Password Security

NOTE:

Three levels of password security are available: Supervisor (1234), User (5678) and Viewer (0000). A
Supervisor has write access to all editable fields. A User has permission to update inventory, make volt­ages changes and navigate through menus. A viewer can view all menus, but does not have permission
to make any changes.

The User password can only changed by the Supervisor from the web interface (see 6 .12 .1). Viewer login
is described in the next section.

Basic authentication is cached in Firefox and the Panel PC, so that the client is not
prompted to re-enter the password again after logging out. Closing the browser clears the
cache and prevents use by unathorized personnel.

2.1.1 Client Login Control

It is possible to have multiple users logged onto the controller. The following table shows the distribution
of allowed logins. (Both a User and a Supervisor are considered to have write access and only one can
be logged on at a time.)

2.2 Software Configuration Loading and Updates

Factory software updates and adjustments to the configuration file are possible through the Ethernet con­nection. The Supervisor can exclude settings and groups of settings when applying changes. A partial
configuration file can also be generated and sent to the CXC (v1.81 and above).

2.3 Customizable User Interface

The web interface can be customized to remove web browser elements that are of no interest to the user.
This menu for customizing the user interface is located in Supervisor > Customize User Interface. When
a group is unchecked, all related UI elements are removed from the browser. This includes menu items,
summary information in the View Live Status and signals and alarms.

2.4 Mixed Rectifier System

All controllers, except the CXCU, allow one type of Alpha Pathfinder model rectifier to work in parallel with
one type of Alpha Cordex model rectifier, for example, a PFM 48V-10kW or PFM 48V-3kW with a CXRF
48-3.6kW. Another example is a PFM 24V-3kW with a CXRF 24-3.1kW. The load share of each rectifier is
based on the percentage of the maximum output current of the rectifier; see Rectifier Report (4 . 7. 2 ).

The Pathfinder rectifiers are not shown under Upgrade Firmware as that submenu applies to Cordex
rectifiers and smart peripherals only.

2.5 Safe Voltage

The Safe Voltage is the voltage that the rectifiers default to if they lose communications with the controller.

The Supervisor can set the default system voltage (Safe Mode) that will be used if the communications to
the Cordex rectifiers fails. This feature has a time delay that varies according to the rectifier. Most rectifi­ers will revert to Safe Mode after five (5) minutes. The rectifier manual lists the default parameters.

Note: In general, the open circuit voltage for VRLA batteries is determined to be a point where discharge
or over charge will not occur.

2.6 Power Save

The Power Save feature enables the Supervisor to improve operational efficiency by running only the
necessary number of rectifiers. For example, when the load is significantly less than the available system
power, the controller shuts down one or more of the rectifiers so that the remaining rectifiers operate with
greater efficiency at a higher current level. A short (one-minute) time delay or hysteresis is built in to avoid
nuisance alarms and to prevent changes if the load is fluctuating.

With Power Save, rectifier usage rotates on a weekly basis to share the service time. Power Save comes
into effect when a minimum discharge or load current (~2.5% of maximum current of one rectifier) is
achieved. Battery charge current limit calculations are based on the rectifiers that are running.

The Power Save feature is suspended during Battery Test mode. See 4.12 . 4.

NOTE:

The Remote Shutdown setting must be enabled for the rectier (see Rectiers > Congure
Rectiers) to operate in Power Save.

2.7 Auto DC Priority

The inverters can be configured to automatically switch to DC Priority mode when a custom alarm is acti­vated. The alarm could be triggered by a digital input such as a signal from an alternative energy source
– a fuel cell for example that has just switched on.

When the custom alarm activates, the CXC automatically switches the Inverters to draw from DC power
as much as possible. When the alarm is deactivated, the command is sent to return to AC Priority. (Cus­tom alarms are configured from Alarms-> Configure Alarms.)

For more information, see section 6.4.7.

2.8 Battery Temperature Compensation

The automatic battery temperature compensation feature (Temp Comp or TC) works with Cordex series
rectifiers that support CAN bus communications and Pathfinder series rectifiers that support RS-485
remote communications. Temp Comp may be active in either the Float (4.9) or Equalize (4.10 ) mode.

Temperature inputs are available on the CXC for monitoring a lead acid battery string. Temperature sen­sor readings can be displayed on the GUI in either the Celsius (°C) or Fahrenheit (°F) scales.

The CXC has the flexibility to display the breakpoints in voltage and temperature. The breakpoints can be
entered as voltages or temperatures.

The detection of a thermal runaway is limited to a programmable Battery Over Temperature Alarm. The
Supervisor can select the temperature that triggers an alarm.

8

0700015-J0 Rev B

2. 8.1 Theory of Battery Temperature Compensation

The battery life expectancy and performance is directly related to the battery ambient temperature. The
optimum battery temperature during operation is 25°C (77°F). Without compensation, battery life is seri­ously compromised at temperatures above 25°C, while battery performance is reduced below 25°C.

Adjusting the battery’s float or equalize voltage to correspond with temperature fluctuations ensures
maximum battery performance and life expectancy. With the CXC, this can be accomplished by using
the software’s built-in automatic temperature compensation function. This function adjusts the system
voltage, ever 60 second, as the temperature changes and provides for a maximum voltage change of

0.1V over this interval.

Temp Comp occurs at standard rates commonly referred to as slope-compensation settings. For maxi­mum performance, the battery slope compensation must be matched to the setting recommended by the
battery manufacturer. Do not confuse this with the slope regulation, which refers to the process of regulat­ing the current among a group of parallel-operating rectifiers.

The Temp Comp feature uses programmable breakpoints, which are the points that Temp Comp ceases.
Further temperature decreases or increases do NOT increase or decrease the output voltage. This pro­tects the connected load and battery from excessive voltages. As Temp Comp is active in either float or
equalize mode, set breakpoints with this in mind.

When temperature compensation is enabled in Equalize Mode, the CXC uses the equalize voltage setting
as the center point around which to make Temp Comp voltage adjustments.

When temperature compensation is enabled in Float Mode, the CXC uses the float voltage setting as the
center point around which to make Temp Comp voltage adjustments.

2.8.2 Operation of Battery Temperature Compensation

The CXC can accommodate up to four sensors that monitor lead acid battery temperatures. If more than
one sensor is used and the temperature readings are within 5°C (9°F) of one another, the temperature
readings are averaged. If the reading differences exceed 5°C, a thermal runaway is assumed in one
battery string and the reading changes from the average reading to the highest. If any reading suddenly
jumps outside the normal range (i.e. leads are cut or opened), that reading is discarded and the associ­ated Temp Sensor Fail alarm is activated. The temperature reading then returns to the average for the
remaining sensors, or to the next highest reading.

Temp Comp has been programmed as a low priority item. All other commands and operations take
precedence over Temp Comp. If a command is issued during a Temp Comp cycle, the cycle will be put
on hold until the command is completed. If any operation is happening when the Temp Comp cycle oc­curs, the cycle is put on hold until the operation is completed. Temp Comp resumes when the command
or operation completes. The Temp Comp feature can be enabled or disabled in the CXC Batteries menu
(“6.5.1 Temperature Compensation” on page 50.

2.9 Battery Auto Equalization

Auto Equalize (Auto-EQ) is a protective feature designed to ensure optimal lead acid battery life and per­formance. With the CXC, auto equalize is used for two basic purposes: (1) for providing a quick battery
recharge after an AC power failure, and (2) as a long-term battery maintenance feature.

Refer to the battery manufacturer’s recommendations for equalization charging.

2. 9.1 Battery Charge Auto Equalize

Battery Charge Auto Equalize can be used after a prolonged AC power failure when the battery voltage
has decreased to a low level.

Once battery voltages have decreased below the auto equalize low voltage threshold, the CXC enters an
armed mode. When AC power returns, the system voltage begins to increase and charges the batteries.

Once the system voltage increases to the high voltage threshold, the CXC enters the equalize mode
and begins to equalize the battery charges for a period specified by the Supervisor in the AUTO-EQ
DURATION submenu. This is done to ensure the EQ duration is not effectively reduced by the time it
takes to recharge the battery to the nominal system voltage.

0700015-J0 Rev B

9

2.9.2 Periodic Auto Equalize

Periodic Auto Equalize can be used for maintaining the long-term integrity of a battery string. Over time,
individual battery cell voltages may vary greatly. To ensure that the batteries remain in optimum condition,
they should be equalize charged at regular intervals. The CXC enables the Supervisor to program the
time between automatic equalize charging of the battery string in the AUTO-EQ INTERVAL submenu.

2.9.3 Battery Current Termination (BCT) Equalize

The BCT Equalize feature provides an alternative method of ending the EQ mode early to prevent over­charging of the battery. Once enabled, it is only active when the EQ mode is caused by a Charge Auto
Equalize.

BCT EQ terminates the Charge Auto EQ when the battery current falls below the BC Threshold setting.
Upon initial activation of the EQ mode that is triggered by the Charge Auto EQ feature, the CXC waits
for one minute of system stabilization time before monitoring the battery current for BCT EQ. After one
minute, the battery current is checked about once per second to see if the current has fallen below the
BC Threshold.

When the battery current falls below the BC Threshold and remains below the threshold for three sec­onds, the EQ duration is replaced with the BCT duration. After this time, the system returns to FL mode.

2.10 Battery Monitor and Charge Current Control

The Battery Monitor feature enhances the CXC’s capability to provide information about the battery to
the user. Charge Current Control helps to increase battery longevity by keeping the battery current within
specified limits.

Charge current to the battery during recharge is limited to a value that is programmed by the Supervisor.
This value is derived from the battery manufacturer’s specification sheet and entered by the Supervisor.

A battery run time prediction is performed while the battery is supplying power to the load. The CXC
collects data to estimate the time it takes for the battery to be drained. If the Battery Monitor feature is
enabled and the battery is sourcing current to the load, a time estimate appears in the Mode Status
screen. A runtime estimate is also available in the Analog Signals display, which can be enabled for
display status in Signals > Configure Signals > Controller Signals.

During an AC outage or Battery Test, the data is collected to calculate a capacity prediction. A capacity
of 80% means that the battery is due to be replaced. The accuracy of this improves as the battery under­goes more discharge cycles.

2.11 Battery Test Scheduler

A battery test scheduler is built into the software. The test can be set to a frequency of a fixed number of
days apart, or set to a specific day of the month.

2.12 Low Voltage Disconnect Operation

Whenever the system parameters require that the LVD be activated, a 60-second countdown and audible
warning begins. When the countdown reaches zero, the LVD is activated. During this countdown, an icon
on the GUI can be pressed to evoke a prompt to inhibit LVD controls – activated by entering the Supervi­sor password. There is a 10-minute time-out for this. See also LVD Inhibit 6.8.2.

2.13 Signals Management

The Supervisor can view and edit a signal equation for a selected signal. The Supervisor can also config­ure custom signals; properties can be modified or disabled as required. All signals in the system can be
selected for a signal equation builder making it possible to combine logic conditions and analog values
to generate an alarm.

The Supervisor can select which Temperature Sensor to enable for the Battery Temp Sensor Signal.

There are 20 Custom Signals which the user can set by either SNMP or using the equation builder. Note
that for any particular signal, only one of these options can be selected. If the user chooses to set by
SNMP, any equation associated with that signal will no longer be evaluated. Similarly, if a signal is select­ed to be set by equation, SNMP “sets” made to that signal will be ignored. Because SNMP only allows

10

0700015-J0 Rev B

integer values and the CXC may require numbers accurate to two decimal places, values are multiplied
by 100 before sending over SNMP. So, for example, to set a signal to a value of “1”, the user should actu­ally do an SNMP set with value “100”. Similarly, a signal with value “1” will be received by SNMP as “100”
and should be divided by 100 to determine the actual signal value. Note also that since signal values are
not saved over a CXC reset (but instead re-evaluated after reset), any value previously set by SNMP will
be lost during reset and the signal will go back to value “0”

2.14 Statistics and Historical Data

The CXC is capable of tracking several statistical parameters on a daily basis: analog statistics, for ex­ample, and triggered items such as battery log and event log.

Data is stored in local memory and can be accessed via a web interface (see Data Logging in Section

6.7. 3 ). The logged data is comma-delimited so it can automatically viewed in rows and columns in MS
Excel. The data is stored on a first-in-first-out basis.

2.14.1 Analog Statistics

All statistics, to a maximum of 90 records (one per day) contain a time stamp and date. Daily analog
statistics include the minimum, maximum and average of:

Load Voltage Load Current

Battery Voltage Battery Current

AC Mains Battery Temperature
Total Rectier Current Average DC Voltage
Average AC Voltage Number of Acquired Rectiers
Number of Sourcing Rectiers Ten Custom Signals

2.14. 2 Battery Log

A maximum of 40 records can be logged for battery statistics and events. The Battery Log contains the
following:

Event Type Capacity Rating

Battery Test Start Time Depth of Discharge

Discharge Duration Time Capacity

Amp Hours Delivered Recharge Duration

Amp Hours Recharge Return Peukert Number

1-5 Max. Midpoint Deviation Discharge Data1

1-5 Max. Midpoint Deviation Recharge Data2

Battery Current/Average Battery Current Battery Temperature/Average Battery Temperature

Battery Voltage/Battery Test End Voltage Open Circuit Voltage

Battery Test Result

During a battery discharge, active battery log information is displayed in a row above the Battery Log.
This information is then no longer available after the battery has finished recharging.

The Battery Log also provides support for very slow discharges. This is accomplished by saving interme­diate battery log information in the event of controller power loss before battery recharge completes.

When a battery test (BT) is started remotely, the battery log shows Remote BT in the Event Type column.

0700015-J0 Rev B

2.14.4 Event Log

The CXC can record up to 500 events. Each unique event is stamped with the date and time. Multiple
events are time stamped for the first daily occurrence and then the accumulated total is shown at the last
daily occurrence of the event. Refer to Relay 7 in the following event log.

Some of the events include the following:

• All alarm events (activation and deactivation).

• Rectifier alarm details.

• Any change of state of the digital inputs.

• Other miscellaneous events; such as, rectifiers being turned off or on due to the Power Save feature.

Once the maximum number of events have been recorded, the oldest events are erased as new events
are added.

2.14.3 Data Logging

This feature of the CXC web interface allows the user to perform complex/custom configurations of the
data gathered by the Alpha controller. Various ways of setting the log frequency/limit and start/stop trig­gers enables greater management of the events for collection.

The data is stored in files showing the records associated with each for easy archiving and retrieval. File
Save Option enables a FIFO (first in first out) or “Stop when full” means of data collection.

Recommended size is up to seven signals and a maximum one thousand entries, as very large log files
may not be viewable. If the datalog screen comes up blank, the log is too large to be displayed.

4.9 Float (FL) Mode

FL is the CXC default mode at start up and during normal system operation. In this mode, the rectifier’s
charge (or output) voltage is driven by the float voltage setting found in the CXC Rectifiers menu, see

6.3.2. Do not adjust the float voltage of the rectifiers when they are in Current Limit.

4.10 Equalize (EQ) Mode

Use the equalize mode to equalize charge a battery string. In this mode, the rectifier’s charge (or output)
voltage is driven by the equalize voltage setting found in the CXC Rectifiers menu, see 6.3.2

A maximum time limit for equalize charging can be programmed to prevent accidental over-charge of a
battery string. This limit is determined by the setting found in the EQ Timeout menu, see 6. 3. 2.1 0 . Do not
adjust the equalize level of the rectifiers while they are in Current Limit.

When operating in EQ mode, the text below the Mode Selection buttons (Figure 18) displays the time
until FL mode in hours.

4.11 Boost (BST) Mode

This feature provides the supervisor with the means to equalize charge the battery at a higher voltage
relative to the connected load. Activation is manual and certain conditions must be met to prevent dam­age to the load. A custom alarm must be created to include all the desired factors that must be taken into
account before activating BST mode. This mode will then only be permitted if the alarm is false.

Once activated, BST mode concludes with a timeout or whenever the status of the custom alarm is true
and reverts to FL mode. BST mode can also be cancelled if the conditions required to activate BST mode
have changed.

4.12 Battery Discharge Test or Battery Test (BT) Mode

The battery discharge test is used to update the status of the lead acid battery capacity.

Manual Activation Manually initiated (tap Mode Selection area and then

BT button) (Figure 18)

Auto-BT Feature BT can be set to run automatically on a periodic basis.

4.12 .1 Definitions

• End/Terminal Voltage — The voltage at which the test ends.

• Timeout — The maximum time the test can run before it is aborted.

• Period in Days — The time between each Auto-BT.

• Battery On Discharge (BOD) Alarm — indicates the battery is discharging.

4.12 . 2 Tips on Using the BT Mode

Use Charge Current Control (6.5.2) to limit the battery recharge current to the battery manufacturer’s
specified maximum value.

The resultant battery capacity estimate will be more accurate if the test is started when the battery is fully
charged. If a discharge has occurred within the last 96 hours, when a mode change to BT is selected, a
dialog box will prompt the user to confirm the mode change.

During a test, the runtime hours are accessible through the Analog Signals display or Mode Status
screen. The runtime hours reflect the time remaining in the test.

The runtime is displayed after the start of an outage and when a BOD condition is detected; i.e., battery
is sourcing current and voltage is below open circuit.

When a test is started by the remote BT feature, the battery log will show “Remote BT” in the Event Type
column.

The Supervisor can enable or disable the feature in
(BATTERIES) BATTERY TEST\AUTO-BT menu. See
section 6.5.4.

26

0700015-J0 Rev B

The BT depth of discharge (DOD) can be accessed via the Analog Signals Display; provides an addi­tional indication of test progress.

BT information is available via the CXC battery log web page when a test is in progress. In addition, the
new battery capacity estimate can be accessed via the Analog Signals display at any time before, during
or after the test.

4.12 . 3 BT Initiation

When the test begins, an entry is made in the event log. If enabled, an alarm provides a warning to indi­cate that a Battery Test is in progress.

The test will continue, depending on the type of rectifier in use, in accordance with the following algo­rithms (as applied to lead acid batteries):

Algorithm 1 — For rectifiers that support Battery Test (BT) mode:

1. A command is sent to put the rectifiers into BT mode.

2. BT mode runs for the period set as Timeout or until BT End Voltage is reached.

Algorithm 2 — For (Pathfinder) rectifiers that do not support BT mode:

1. Rectifiers are commanded to go to nominal voltage.

2. The rectifiers are periodically scanned to be sure that they do not begin sourcing current. When 3%
DOD is reached and the rectifiers are still not sourcing current, the rectifiers are turned off.

3. The rectifier float setting is reset to the setting stored in the system controller.

4. When the system voltage reaches the end (termination) voltage or a timeout occurs, the system
controller will command the rectifiers to turn ON and enter FL mode.

4.12 .4 Activity During BT Mode

Temp Comp and Power Save features are suspended during a battery test.

When the battery is discharging, a BOD alarm is active.

During a test, the mode symbol in the upper left corner of the GUI updates to “BT.”

Runtime estimate begins at 3% DOD.

Capacity estimate also begins at 3% DOD, but is not stored unless DOD > 20%; the point at which rea­sonable accuracy can be assured.

4.12 . 5 AC Failure During BT Mode

If the AC fails during a battery test, the test will be aborted. This will place the rectifiers into a state that
will enable them to resume providing power to the load when AC returns. If the Runtime is being dis­played, it will continue to update.

4.12 .6 Addition of Rectifiers During BT Mode

If rectifiers are added to the system when a battery test is active, they will be placed into the same state
as the other rectifiers. They are:

• Placed into BT mode (for rectifiers that support BT mode), or

• Placed into remote shutdown, or

• Set to the same voltage as the other rectifiers.

0700015-J0 Rev B

27

4.12 .7 Conditions to Watch for During BT Mode

If the voltage drops below 47 V before or when 3% DOD is reached, the test is aborted and the battery
capacity is set to 0% (resulting in a Battery Capacity Low alarm). This provides an indication that the bat­tery is very weak . The battery capacity must be manually reset to 100%, or to the percentage of expect­ed battery capacity before the next battery test is started, in order for the battery monitor to again attempt
to compute the battery capacity.

If rectifiers are seen to be sourcing current during the test and the battery ceases to be discharging, the
test is aborted.

4.12 . 8 Cancelling BT Mode

BT mode can be cancelled by changing mode to FL or EQ (see section 4.8).

4.12 .9 Battery Discharge Test Completion

The test is considered complete once the battery begins to charge. This could be due to the test ending
from timeout, the system reaching the end (termination) voltage or an abort condition.

Once the battery begins to charge, the recharge cycle begins. Live battery recharge information is avail­able from the battery log web page.

4.12 .10 Remote BT Mode

This feature will force a transition to BT mode when a user-defined condition (custom alarm) is true.

When this condition is true, BT mode is entered regardless of the regular safety checks that are per­formed during manual or automatic changes to BT mode. BT mode stays active as long as the condition
remains true.

A check box is used to enable/disable this feature. The default is disabled. If the condition is true and the
check box is disabled, then the system will be put into FL mode.

If the condition becomes false, disabled, invalid, or the (assigned custom alarm) equation is empty, the
system will be put into FL mode.

This feature is exclusive for the Cordex series of rectifiers. If Remote BT is active and a rectifier other than
the Cordex series is added to the system then Remote BT will be aborted.

6.2 Converters

This menu category consists of converter alarms and controls. Parameters can be set/accessed such as
output voltage, OVP, high/low voltage alarms, and start delay.

The converter defaults are based on the system voltage of either 24 or 48 VDC.

At present, the converter software does not support:

• Two types of converters simultaneously

• 12, 125, and 220 VDC systems.

Other features include:

Active voltage control Inventory update
Converter locate Loadsharing

Firmware upgrade Major and minor alarms

6. 2.1 Converter Report

This feature provides the user with a list report (see 4. 7. 2 , Figure 17) of all acquired converters in the
system. The first column lists the serial numbers of the converters. The report then displays the output
current of each converter under the Amps column (or toggle for % of maximum output) and the number
of active alarms under the Alarms column (if that converter is issuing an alarm). The right most column
displays the number of settings out of tolerance.

Select a converter and tap View Details to produce another list showing details of the entire converter
alarms and settings that are out of tolerance.

6.2.2 Configure Settings

This feature allows the user to configure settings (via menu items) for all of the acquired converters in the
system; such as:

Output Voltage Start Delay
OVP Enable CL Alarm

Input Voltage Shutdown Input Voltage Restart

6.3 Rectifiers

This menu category consists of rectifier alarms and controls. Parameters can be set/accessed such as
float/equalize voltages, high/low voltage alarms, and start delay.

6.3 .1 Rectifier Report

This feature provides a list report (see 4 .7. 2 , Figure 17), of all acquired rectifiers in the system. The first
column lists the serial numbers of the rectifiers. The report then displays the output current of each recti­fier under the Amps column (or toggle for % of maximum output) and the number of active alarms under
the Alarms column (if that rectifier is issuing an alarm). The right most column displays the number of
settings out of tolerance (OOT per web interface).

Select a rectifier and tap View Details to produce another list showing details of the entire rectifier alarms
and settings that are out of tolerance.

6.3.2 Configure Settings

Figure 37 — Configure Settings (rectifiers) window

The menu items described below can be configured via a virtual numeric keypad ( ) or by toggling the
listed item. For a basic programming example, see 4.7. 3.

6.3 .2.1 Float (FL) Voltage

The Supervisor can set the system BATTERY VOLTAGE (measured at an analog input channel) to the
desired float voltage value. Float voltage charges the battery string and supplies the load. Normally, the
power system will operate in the float mode. This setting should have a minimum of LVD + 1 V and a
maximum of OVP – 1 V.

6.3.2.2 Equalize (EQ) Voltage

The Supervisor can set the system BATTERY VOLTAGE (measured at an analog input channel) to the de­sired equalize voltage value. Equalize voltage charges the battery string at a higher than normal voltage
to either recharge batteries after a power failure or to balance individual cell voltages. Periodic equalizing
of the battery string may be required to optimize battery performance and life. This setting should have a
minimum of LVD + 1 V and a maximum of OVP – 1 V.

6.3.2.3 Battery Test (BT) Voltage

The Supervisor can set the Battery (Discharge) Test Voltage to the desired value during the test (mode).
This setting should have a minimum of LVD + 1 V.

6.3.2.4 Safe Voltage

The Supervisor can set the default system voltage (Safe Mode) in the event that communications to Cor­dex rectifiers should fail. See 2.5 for more details about this feature.

6.3.2.5 OVP Voltage

The Supervisor can program one OVP setting for all connected rectifiers. OVP will disable a rectifier that
outputs an abnormally high voltage.

6.3.2.6 Low Voltage Alarm (LVA)

The Supervisor can program one LVA setting for all connected rectifiers. LVA serves as a warning to the
user indicating that output voltage is dropping.

6.3.2.7 High Voltage Alarm (HVA)

The Supervisor can program one HVA setting for all connected rectifiers.

HVA serves as a warning to the user indicating that output voltage is rising. This value should be less
than the OVP setting in order for the HVA to work effectively.

6.3.2.8 Current Limit (CL)

This menu item sets the level as a percentage at which current limiting activates in all connected recti­fiers. Current limiting is a primary response to output over current situations. If the output current on the
rectifiers exceeds the current limit setting, their output voltage will automatically decrease but will main­tain the current output at the current limit level. This prevents potential damage to the rectifiers.

If the CXC finds rectifiers in the system that cannot meet the default current limit value, the CXC will cor­rect its default limit setting to match the rectifiers.

40

0700015-J0 Rev B

6.3.2.9 Power Limit (PL)

This menu item sets the level as a percentage at which power limiting activates in all connected Cordex
rectifiers.

6.3 .2.10 EQ Timeout

This menu item controls the maximum equalize time setting for all connected rectifiers. This control is
designed to prevent accidental over-charge of the batteries. CXC will send the command to change the
equalize time-out setting in all the rectifiers.

6.3. 2.11 BT Timeout

This menu item controls the maximum duration of the Battery Test.

6.3 .2.12 Slope (Pathfinder rectifiers only)

This menu item sets all connected rectifiers to the same slope adjustment value. Slope determines the
regulation percentage of the current between rectifiers in a group. When load sharing is initialized, CXC
will send commands to the rectifiers to try to adjust their output voltage within this slope range. The recti­fiers should have their output voltage as close to being equal, in order to balance (or share) the load
current between them.

6.3 .2.13 Backlight Timeout (Pathfinder rectifiers w/LCD only)

This menu item controls the amount of time of GUI inactivity permitted before the rectifier automatically
turns off the LCD backlight.

6.3 .2.14 Security Code (Pathfinder rectifiers w/LCD only)

The Supervisor can program one security access code for all connected rectifiers. CXC logs in each of
the rectifiers as Factory Access and sends the direct command to change the access code.

6.3 .2.15 Module Start Delay

This menu item controls the stagger-start timer for all connected rectifiers.

With start delay, rectifiers start up in a time-delayed sequence. This prevents excessive loading of the
AC source. For example, setting a start delay time of 5 seconds will cause rectifier#1 to start at 1 sec­ond, rectifier#2 at 5 seconds, rectifier#3 at 10 seconds, etc. In the case where the start delay exceeds
the maximum range, the next rectifier in sequence will start its delay at zero and increment again by the
value specified in this menu item.

When the rectifier Module Start Delay is set to 0 s, all the rectifiers start with a 0 sec delay.

6.3 .2.16 System Start Delay

This menu item controls the amount of time, in seconds, before the stagger-start timer commences, see
the previous section.

6.3 .2.17 Soft Start Ramp Rate (Cordex rectifiers only)

The Supervisor can select the soft start ramp rate (normal or fast). Current limit ramps up at about
t12%/sec during normal soft start and 100%/sec during fast.

For systems without batteries, select the Fast setting for the Soft Start Ramp Rate.

6.3 .2.18 Temp Display Scale (Pathfinder rectifiers w/LCD only)

The Supervisor can select the temperature display scale (Celsius or Fahrenheit).

6.3 .2.19 Check to Enable

The Supervisor can toggle (enable or disable) the following list of items:

• CL and PL Alarm

• Remote Shutdown (Cordex rectifiers only; affects operation of Power Save, see below)

• Local Access Alarm (Pathfinder rectifiers w/LCD only)

• Ramp Test (Cordex rectifiers only)

0700015-J0 Rev B

41

6.3.3 Power Save

The Supervisor can improve operational efficiency when conditions warrant by running only the neces­sary number of rectifiers. The remote shutdown setting (enable or disable) affects correct operation of the
Power Save feature. See also 2.6 for more details.

6.3.3.1 Enable

The Supervisor can control the CXC Power Save feature.

6.3.3.2 Redundant Rectifiers

The Supervisor can specify the number of extra rectifiers to turn on.

6.3.3.3 Max (Maximum) Power Usage

The Supervisor can specify the percentage (of maximum power usage) per rectifier module used in the
computation of the Power Save feature. This works to avoid rectifiers operating continuously at greater
than the set limit (i.e. 95%) and going into current limit frequently due to load surges or power limit condi­tions; such as, low line voltage or high temperature.

6.3.3.4 Phase Mapping

The user can assign or map a rectifier per input signal for individual phase voltage readings:
