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.

Refer to the Installation manual for hardware details.

1.2 User Interface (see Chapter 4)

Located on the front panel of each CXCM (or CXCP or CXCR) model is a 160-x-160-pixel touch screen liquid crystal display (LCD) similar to that used in a personal digital assistant (PDA), see Figure 1. This graphical user interface (GUI) enables a person to interact with screen selectable items.

Refer to the back of this manual for Factory Service and Technical Support contact information

For CXC models with a touch screen display, the use of a PDA type stylus is recommended and may be required when accessing the on-screen keyboard for some adjustments.

Figure 1–CXC models showing features of main menu touch screen

The CXC will provide feedback during operation with different audible tones for alarms, invalid password, and menu navigation.

NOTE: Other models, such as the CXCI, only have a 4-digit display for monitoring system voltage and current. Without a

touch screen display, system setup and management is performed exclusively with the web interface, see Section

4.10.

CAUTION Do not connect anything other than the Alpha modem and Alpha-supplied DB-9 cable to the D-sub port on the front of the CXCI.

A step by step connection wizard – provided to establish remote communications with the CXC – is available via the Alpha website (www.alpha.ca

Battery Information – provides an additional window to enter/view the manufacturer’s data for the batteries in the system; e.g., for inventory purposes.

Alarm Configuration Screen Enhancements – provides a list of all alarms in one place (via web browser). The configuration of most alarms may be done on this one screen.

Alarm Tone – enables the Supervisor to enable/disable the audible alarm buzzer (tone). Battery Test Alarm – provides a warning to indicate that a Battery Test is in progress. Invalid Battery Voltage Alarm – provides for indication of invalid battery charging voltage; e.g., in the event that

the sense leads have become disconnected. SNMP Enhancements – provides SNMP/Severity level (numeric) and enables CXC supervisor to set the

scheme. AC Mains Voltage Correction – provides the means to apply a correction factor to the reading coming from the

rectifier. ADIO Enhancements – enables the Supervisor to configure individual signals for an ADIO (Analog Digital Input

Output) Device; i.e., Cordex Smart Peripherals.

Custom Signal Units – enables the Supervisor to set the units value for Custom Signals; e.g., V, AH, mm, etc. LVD DOD Control – enables the Supervisor to configure each LVD control for activation once the percentage of

Depth of Discharge (DOD) has increased above a threshold.

SNMP Community Settings – enables the Supervisor to configure CXC SNMP community settings. SNMP Trap Recovery – enables the CXC SNMP agent to hold traps in a buffer during a network block out. Event Notifications – Multiple SNMP and SMTP Destinations – enables the Supervisor to add up to eight (8)

separate destinations for SNMP and SMTP dial-out or e-mail notifications. Test Relays – provides a message of warning to the CXC operator before allowing the toggling of an LVD relay

and allows the user to cancel the operation. Argus MIB File Enhancements – provides separate object identifier (OID) for a ctive and cleared alarm traps.

Alarm status and signals are reconstructed into tables and sub tables to allow for future expansion while remaining backward compatible with already defined alarms and signals.

Log File Cleanup – provides improved event log file management by filtering and condensing repetitive rectifier events on a daily basis. File retrieval has been updated for sorting by name and by chronological order. The display of log information has also been improved for ease of user navigation.

applying changes. A partial configuration file may be generated and sent to CXC (v1.81 and above).

CXCI Modem Support

– enables connectivity to the CXCI’s new front D-sub port with the Alpha modem and

Alpha-supplied DB-9 cable.

Alpha Technologies Ltd. 034-136-C0 Rev B WC

1.3.7 New Features (since version 1.8)

The following changes/updates have been incorporated into version 1.9 of the CXC software:

Web Interface Facelift – provides more efficient access to software features. Speed/responsiveness has been improved over previous version (testing has shown up to four times faster). Each page can be accessed individually; for example, users with slow interfaces, such as modem, do not have to navigate to specific pages as before.

Modbus® Support – enables CXC communication of alarms and live signals in RTU encoded data format using Modbus protocol (messaging structure developed by Modicon®) upon query via TCP to any Modbus supervisor or master.

Remote Battery Test Mode – enables the Supervisor to define a condition (custom alarm) that will force a transition to battery test mode once the condition is met. BT mode stays active as long as the condition remains true. This feature is exclusive for the Cordex series of rectifiers.

ADIO Support for 4R/8D I/O Module – allows configuration of this new module in the digital alarms or custom alarm sections of the menus; where the alarm condition can be associated with a digital input and mapped to a relay. The 4R/8D I/O module is a Cordex Smart Peripheral designed to expand the CXC I/O by four output relays

and eight digital inputs.

Temp Comp in EQ Mode (enable/disable) – allows the supervisor to enable or disable automatic battery temperature compensation in equalize mode independently from float mode.

Boost Mode – 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.

Visit the Alpha website at www.alpha.ca for the latest manual and product downloads

Custom/User Alarms – have increased in number from 5 to 20.

Battery Log – 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.

1.3.8 New Feature for version 1.93

ADIO Support for Cordex Battery Monitor System (BMS) – enables connectivity with Alpha’ new

BCMC module – a Cordex Smart Peripheral – designed to monitor a number of voltages, currents and temperatures in battery strings via a number of remote devices that are managed through a ring data network. Configuration is performed in the signals section of the CXC’s menus.

1.3.9 New Feature for version 1.95

Simplified BCT EQ Threshold – from rate of change to an absolute current value.

The BC Rate of Change setting used to be the rate of change of battery current in units of A/H. This setting has changed and is now BC Threshold in units of A.

NOTE: When upgrading to v1.95 or later, users of the BCT EQ feature must re-evaluate the BC

Threshold setting and enter a new value since the units of the setting has changed.

1.3.10 New Feature for version 1.97

Cordex DC-DC Converter (CXD) Support – enables the Supervisor to configure converter settings,

display and read analog values; similar to the system controller features applied to the Cordex rectifier series.

The converter defaults will be based on the system voltage if it is either 24 or 48Vdc.

NOTE: At present, the converter software does not support:

 Two types of converters simultaneously  12, 125, and 220Vdc systems.

Other features include:

 Active voltage control  Firmware upgrade  Loadsharing  Converter locate  Inventory update  Major and minor alarms

Alpha Technologies Ltd. 034-136-C0 Rev B WC

1.3.11 New Features (since version 1.97)

The following changes/updates have been incorporated into version 2.0 of the CXC software:

Counters and Timers – counters enable the Supervisor to monitor the number of times a particular event occurs.

Timers are used to measure the amount of time since an event occurred or the amount of time between two events. These features are suitable for general-purpose signals that can be used in Custom Signal or Custom Alarm equations.

Dynamic Current Limit – enables the Supervisor to change the battery current limit based on the status of a digital input; such as, when powering a system with a generator, to limit battery recharge current to prevent the generator from overloading. See Dynamic Charge Current Control (CCC) feature.

ALCO Enhancements – enables the user to silence the alarms for a set duration (in minutes). The user may also enable or disable cutoff of each of the following when ALCO is pressed:

 Audible alarm  Alarm relays  E-mail  SNMP.

Printable Configuration (Config) – enables the user to print the total CXC configuration (for a particular controller) via a Print button on the Logs&Files > Manage Configuration File page.

Equipment Inventory – a new User Inventory page allows the user to enter up to twenty inventory items. Additionally, a System Inventory page enables the user to view a single list of all CAN connected devices, user inventory items and battery information items. Previously, devices would only be shown on the individual category pages; e.g., rectifiers connected shown on the Rectifier section.

Refer to the back of this manual for Factory Service and Technical Support contact information

SNMP Related Features – is comprised of these new items:

 Add Trap Acknowledge (Inform)

CXC will wait for SNMP Manager (software) to acknowledge that it has received a trap. If the manager does not acknowledge within a certain amount of time, the trap will be resent.

 Timestamp Varbind

Data added to the SNMP trap to indicate the time of the event that triggered the trap to be sent.

 Alarm Trigger Varbind

Data added to the SNMP trap that shows the analog value that triggered an alarm activation or deactivation.

 Multiple Community Strings

The user may enter more than one set of SNMP community strings. This is to permit multiple SNMP NMS programs, with different community strings, to connect to the CXC. A company with multiple NMS's, each in a different region, with a different community string, will find it easier to connect to the CXC from various places.

Static Calibration – enables the Supervisor to calibrate Controller analog inputs and ADIO (except BCMC) analog inputs without the need for a live signal at the input; especially useful for calibrating current inputs for systems in the field.

Scheduler – enables the Supervisor to use the system time and date as operands in custom alarm and signal equations.

Modbus® and SNMP – additions were made for converter alarms and signals.

1.3.12 New Features since version 2.03

The following changes/updates have been incorporated into version 2.04 of the CXC software:

 The battery log will be closed off when 96 hours has elapsed since the start of the recharge cycle. This is

in addition to the existing functionality that closes off the log when the returned AH reaches 115% of the rated capacity during the recharge cycle.

 Improved response of charge current control when lithium-ion batteries are installed. Lithium-ion batteries

are detected by scanning the battery information and looking for the keyword “lithium” or “li-ion” in the model comment fields.

 The rectifier start delay algorithm now allows a setting of 0 s instead of the former minimum of 1 s.

2 Quick Start

2.1 Applying Startup Power

1. Initiate startup routine by applying power to the CXC; e.g. close battery breaker or close converter and

rectifier input and output breakers.

NOTE: The CXC will perform a short self-test as it boots up. Alarm alerts are normal. The LEDs perform a scrolling

pattern to indicate there is activity. Please wait.

2. Check and adjust alarms and control levels in the CXC’s submenus.

3. Check and adjust group settings in the CONVERTERS and RECTIFIERS submenus; e.g. float, equalize

voltage, etc.

4. Verify COMMUNICATIONS settings as needed.

5. Program the CXC’s TEMP COMP and AUTO EQUALIZE settings as needed.

6. Test relay OUTPUT ALARM\CONTROLS as needed; e.g. Major Alarm, CEMF, etc.

2.2 Remote Communications (see Chapter 9)

The CXC can be set up, monitored and tested with a RS-232 serial data connection, ETHERNET 10/100 Base-T or over a phone line using a modem. Some standard scenarios are described below:

 Network (TCP/IP secured by user) to CXC rear Ethernet port.  Computer to CXC via RS-232 serial data connection (PPP) using a null modem cable connected to the Craft

port (front panel RS-232).

 Laptop to CXC via direct Ethernet connection using a standard crossover cable.  External modem to CXC via RS-232 serial data connection using a straight through cable connected to the

rear RS-232 port.

 Internal modem (see ordering options).

CAN bus (located next to the Ethernet port) is provided for connection to the Cordex series of converters and rectifiers.

RS-485 bus provides a secondary connection for products (e.g., Pathfinder rectifiers) that do not support the CAN bus interface.

2.3 Trouble-shooting Tips

See Trouble-shooting chapter for more information.

2.3.1 Converter and Rectifier Tips

The Cordex Converter (CXD) Rectifier (CXR) series modules are plug and play. When a CXD or CXR module is added to the system, the CXC will detect and update the inventory automatically.

If CXD or CXR module communication has failed, or a module has been removed from the system, an INVENTORY UPDATE

For the Pathfinder series of rectifiers, ensure that the:

 Rectifiers are in NORMAL OPERATING MODE  REMOTE ACCESS is ENABLED  REMOTE ADJUST is ENABLED  BAUD RATE is set to 9600 baud.

2.3.2 Cordex Controller Tips

Use the CXC GUI (Section 4.2) or web interface (4.10) to ensure that the operating levels (e.g. input/output voltage, converter voltage, etc.) are within operating parameters of alarm and control thresholds.

must be initiated manually.

Should Inventory Update fail: a) check cable & connections; b) check settings under System Info/System Configuration for correct voltage.

3 Standard Features

The CXC provides centralized setup, control and monitoring of a communications power system.

3.1 Password Security

Two levels of password security are available: User and Supervisor. The same password cannot be used for both.

User access (Section 4.7.1) enables navigation through menus, but no changes are permitted.

Supervisor access enables navigation and changes to parameters including Supervisor password, see 6.11.1. The Supervisor may change the User password only via the web interface.

3.2 Software Configuration Loading and Updates

Factory software updates and adjustments to the configuration file are possible through the RS-232 serial port or Ethernet connection. The Supervisor may exclude settings and groups of settings when applying changes. A partial configuration file may also be generated and sent to CXC (v1.81 and above).

3.3 Mixed Rectifier System

The CXC enables the use of one type of Alpha Pathfinder model rectifier working in parallel with one type of Alpha Cordex model rectifier; for example, PFM 48V-10kW or PFM 48V-3kW with CXRF 48-3.6kW. Another example is PFM 24V-3kW with CXRF 24-3.1kW. The menu item Rectifier Protocol is no longer required and has been removed. The load share of each rectifier is based on the percentage of maximum output current of the rectifier; see Rectifier Report (4.4.2). In some cases, e.g. battery test algorithm, the system functionality will be limited to that of the Pathfinder rectifiers while the communications will equal that of the Cordex controller.

NOTE: The Pathfinder rectifiers will not be shown under Upgrade Firmware as that submenu applies to Cordex rectifiers

and smart peripherals only.

3.4 Safe Voltage

Safe Voltage is the voltage that the rectifiers will default to if the controller fails. In general terms, the open circuit voltage for VRLA batteries is determined to be a point where discharge or over charge will not occur.

The Supervisor can set the default system voltage (Safe Mode) in the event that communications to Cordex rectifiers should fail. This feature has a time delay (a function of the rectifier); the activation value is five (5) minutes. The rectifier manual lists the default parameters.

3.5 Power Save

This feature will enable the Supervisor to improve operational efficiency when conditions warrant by running only the necessary number of rectifiers. For example, when the load is significantly less than the available system power, the controller will shut down one or more of the rectifiers so that the remaining rectifiers may operate with greater efficiency at a higher current level. A short (one-minute) time delay or hysteresis is included to avoid nuisance alarming and to eliminate changes if the load is fluctuating.

In addition, with Power Save, rectifiers are rotated into use on a weekly basis to share the service time.

When Power Save is enabled, it takes effect when a minimum discharge or load current (~2.5% of maximum current of one rectifier) is achieved.

Charge or battery current limit calculations are made based on rectifiers that are running.

The Power Save feature is suspended during Battery Test mode, see 4.3.4.6.

NOTE: The remote shutdown setting (Cordex series only) enables the function in the rectifier. The Power Save feature

uses this functionality when a Cordex rectifier is commanded to shut down.

The Power Save feature does not work with the Alpha RSM 48/100 series of rectifiers.

Alpha Technologies Ltd. 034-136-C0 Rev B WC

3.6 Battery Temperature Compensation

The automatic battery temperature compensation (Temp Comp or TC) will function 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 float (4.3.1) or equalize (4.3.2) 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 Celsius (°C) or Fahrenheit (°F) scales.

The CXC will have the flexibility to display the breakpoints in voltage as well as temperature, also enabling them to be entered as voltage or temperature.

The detection of thermal runaway will be limited to a programmable Battery Over Temperature Alarm. This will enable the Supervisor to select a temperature that will trigger an alarm.

3.6.1 Theory of Battery Temperature Compensation

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

Adjusting the battery’s float or equalize voltage to correspond with temperature fluctuations will ensure maximum battery performance and life expectancy. With the CXC, this may be accomplished by using the software’s built-in automatic temperature compensation function.

Visit the Alpha website at www.alpha.ca for the latest manual and product downloads

This function works by adjusting the system, every ten minutes, as the temperature changes and provides for a maximum voltage change of 0.1V over this interval.

While this may seem like a small voltage change, even if the battery had a temperature compensation slope as high as 5.5mV per C, the CXC would still be able to track a temperature change in the battery of up to 4.5C or 8F per hour. Due to the large thermal mass of the battery string, even an extreme rise or drop in environmental temperature would be very unlikely to cause this kind of temperature change in the battery over a one hour period.

Temp Comp occurs at standard rates commonly referred to as slope-compensation settings. For maximum performance, it’s important to match the battery slope compensation with the setting recommended by the battery manufacturer. This is not to be confused with slope regulation; which refers to the process of regulating current among a group of parallel-operating rectifiers.

The Temp Comp feature has programmable breakpoints. These are the points at which Temp Comp will cease. Further temperature decreases or increases will NOT increase or decrease the output voltage. This protects the connected load from excessive voltage conditions. As Temp Comp is active in either float or equalize mode, breakpoints should be set with this in mind.

The Temp Comp feature also incorporates fail-safe circuitry to prevent it from driving the rectifier system to a voltage higher than is suitable for the load or battery.

3.6.2 Operation of Battery Temperature Compensation

The CXC can accommodate up to four sensors for lead acid battery temperature monitoring. If more than one probe is used and the temperature readings are within 5°C (9°F) of one another, the temperature readings will be calculated for the average. If the readings difference exceeds 5°C, it is assumed that thermal runaway is occurring in one battery string and the calculation changes from average to the highest reading. If any reading is suddenly outside the norm (i.e. cut leads or open leads), that reading is discarded and the associated Temp Sensor Fail alarm is issued. The temperature calculation will then return to the average of the remaining sensors, or next highest reading.

Temp Comp has been programmed as a low priority item; all commands and operations will 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 will be put on hold until the operation is completed. Temp Comp will resume when the command or operation is completed.

The Temp Comp feature can be enabled or disabled in the CXC’s Batteries menu.

3.7 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: first, for providing a quick battery recharge after an AC power failure, and second, as a long-term battery maintenance solution.

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

3.7.1 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 the batteries have decreased beyond the auto equalize low voltage threshold, the CXC will enter an armed mode. When AC power returns, the system voltage begins to increase, which charges the batteries.

Once the system voltage increases to the high voltage threshold, the CXC enters the equalize mode and begins to equalize charge the batteries 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 back to the nominal system voltage.

3.7.2 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. As a result, to ensure that 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.

Refer to the back of this manual for Factory Service and Technical Support contact information

3.7.3 Battery Current Termination (BCT) Equalize

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

BCT EQ will terminate Charge Auto EQ when the battery current falls below the BC Threshold setting. Upon initial activation of EQ mode – that is triggered by the Charge Auto EQ feature – the CXC will wait 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.

3.8 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 will help increase battery longevity by keeping the battery current to within specified limits.

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

A battery run time prediction will be performed while the battery is supplying power to the load. The CXC will collect data to estimate the time it will take 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. 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, data will be collected to calculate a capacity prediction. A capacity of 80% means the battery is due to be replaced. The accuracy of this will improve as the battery undergoes more discharge cycles.

Alpha Technologies Ltd. 034-136-C0 Rev B WC

3.9 Low Voltage Disconnect Operation

Whenever the system parameters require that the LVD be activated, a 60-second countdown and audible warning will commence. When the countdown reaches zero, the LVD will be activated. During this countdown, an icon on the GUI may 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 6.7.2.

3.10 Signals Management

The CXC enables the Supervisor to view and edit a signal equation of the selected signal. The Supervisor may also configure custom signals; properties may 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 (including any smart peripheral temperature sensors) is enabled for Battery Temp Sensor Signal.

3.11 Statistics and Historical Data

The CXC is capable of tracking several statistical parameters on a daily basis; e.g., analog statistics or triggered items (listed below), such as, battery log and event log, see Data Logging (web interface only), Section 6.6.3.

Data is stored in local memory and may be accessed via a web interface. The logged data is comma-delimited such that it can be automatically viewable in rows and columns in MS Excel. The data is stored on a first-in-firstout basis.

Visit the Alpha website at www.alpha.ca for the latest manual and product downloads

3.11.1 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 Rectifier Current Average DC Voltage Average AC Voltage Number of Acquired Rectifiers Number of Sourcing Rectifiers Ten Custom Signals

3.11.2 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 by the remote BT feature, the battery log will show “Remote BT” in the Event Type column.

Alpha Technologies Ltd. 034-136-C0 Rev B WC

3.11.3 Event Log

In addition, the CXC can record up to 500 events. All events are stamped with the date and time. Some of the events available 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.

3.11.4 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.

4.3 Mode Status (active area) and Temp Comp Indication

The CXC has four modes of operation: float (FL), equalize (EQ), boost (BST) and battery test (BT). The mode, along with temperature compensation (TC or Temp Comp) activation, is indicated in the top left “active area” of the GUI, see Figure 2. The time duration, until the mode changes, will also be shown in that active area.

Tap this active area to enter a new screen, or window of operation, for mode selection, see Figure 7 below:

Mode (+Temp Comp) displa

Additional functions display here; such as,

countdowns and status of battery runtime

4.3.1 Float (FL) Mode

This is the CXC’s default mode at start up and during normal system operation. When in this mode, the rectifier’s charge (or output) voltage is driven by the float voltage setting found in the CXC’s Rectifiers menu, see 6.3.2. The icon (message) FL will display on the GUI’s upper left corner (Figure 2) when the CXC is operating in float mode. Do not adjust the float voltage of the rectifiers when they are in Current Limit.

When operating in a mode other than float mode, tap the FL mode selection button to return to the defaultoperating mode. Tap the “check mark” button in the lower right corner of the GUI to verify the action and return to the previous screen.

4.3.2 Equalize (EQ) Mode

The equalize mode is used to equalize charge a battery string. This mode can be selected via the Mode Status active area and by tapping the EQ mode selection button or by sending an external command; e.g., via web

interface. When in this mode, the rectifier’s charge (or output) voltage is driven by the equalize voltage setting found in the CXC’s Rectifiers menu, see 6.3.2. The EQ icon will display when the CXC is operating in equalize mode.

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 6.3.2.10. 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 (shown above) will display the time until FL mode in hours. Tap the “check mark” button in the lower right corner of the GUI to verify the action and return to the previous screen.

4.3.3 Boost (BST) Mode

This feature (see 0) 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 that are required in order to activate BST mode have changed.

Alpha Technologies Ltd. 034-136-C0 Rev B WC

Refer to the back of this manual for Factory Service and Technical Support contact information

4.3.4 Battery Discharge Test or Battery Test (BT) Mode

The battery discharge test is used to update the status of the lead acid battery capacity. BT can be set to run automatically or can be initiated manually (via Mode Selection button).

4.3.4.1 Definitions

End/Terminal Voltage — The voltage at which the test will end or terminate.

Timeout — The maximum time the test will be permitted to run before it is aborted.

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

Battery On Discharge (BOD) Alarm — This alarm will indicate that the battery is discharging.

4.3.4.2 Manual Activation

The user can manually activate the test by tapping the BT mode selection button (Figure 7).

4.3.4.3 Auto-BT Feature

This feature will enable the CXC to start a test automatically on a periodic basis. The Supervisor may enable or disable the feature in (BATTERIES) BATTERY TEST\AUTO-BT menu, see

6.4.5.2.

4.3.4.4 Tips on Using the BT Mode

Use Charge Current Control (6.4.3) 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 recent 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 will be accessible through the Analog Signals display or Mode Status screen. The runtime hours will reflect the time remaining in the test.

The runtime will be 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 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’s 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.

Alpha Technologies Ltd. 034-136-C0 Rev B WC

Visit the Alpha website at www.alpha.ca for the latest manual and product downloads

4.3.4.5 BT Initiation

When the test begins, an entry will be made in the event log. If enabled, an alarm will provide 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.

4.3.4.6 Activity During BT Mode

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

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

During a test, the mode symbol in the upper left corner of the GUI will be similar to the FL mode symbol except that the letters “FL” will be replaced with “BT.”

Runtime estimate begins at 3% DOD.

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

4.3.4.7 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.

4.3.4.8 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 will be:

 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.

4.3.4.9 Conditions to Watch for During BT Mode

If the voltage drops below 47V 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 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.

4.3.4.10 Canceling BT Mode

BT mode can be cancelled by changing mode to FL or EQ.

. The battery capacity must be manually reset to 100%,

In some cases, incorrect battery parameters can cause this condition to occur with a good battery.

Alpha Technologies Ltd. 034-136-C0 Rev B WC

4.3.4.11 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.

4.3.4.12 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.

NOTE: 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.

The menu items described below may be configured via a virtual numeric keypad (5.1.5) or by toggling the listed item. For a basic programming example, see 5.2.

6.3.2.1 Float (FL) Voltage

This menu item enables the Supervisor to 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 + 1V and a maximum of OVP – 1V.

6.3.2.2 Equalize (EQ) Voltage

This menu item enables the Supervisor to 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 + 1V and a maximum of OVP – 1V.

6.3.2.3 Battery Test (BT) Voltage

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

6.3.2.4 Safe Voltage

This menu item enables the Supervisor to set the default system voltage (Safe Mode) in the event that communications to Cordex rectifiers should fail. See 3.4 for more details about this feature.

Alpha Technologies Ltd. 034-136-C0 Rev B WC

6.3.2.5 OVP Voltage

This menu item enables the Supervisor to 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)

This menu item enables the Supervisor to 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)

This menu item enables the Supervisor to 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.

Visit the Alpha website at www.alpha.ca for the latest manual and product downloads

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 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)

This menu item enables the Supervisor to 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.

Alpha Technologies Ltd. 034-136-C0 Rev B WC

Refer to the back of this manual for Factory Service and Technical Support contact information

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 s 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 6.3.2.15 above.

6.3.2.17 Soft Start Ramp Rate (Cordex rectifiers only)

This menu item enables the Supervisor to select the soft start ramp rate (normal or fast).

Current limit ramps up at about 12%/s during normal soft start and 33%/s 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)

This menu item enables the Supervisor to select the temperature display scale (Celsius or Fahrenheit).

6.3.2.19 Check to Enable

This menu item enables the Supervisor to toggle (enable or disable) the following list of items:

6.3.3 Power Save

This feature will enable the Supervisor to 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 3.5 for more details.

6.3.3.1 Enable

6.4.6 Battery Current Termination (BCT) Equalize

Refer to Section 3.7.3 for feature overview.

Visit the Alpha website at www.alpha.ca for the latest manual and product downloads

Since the BC Threshold is in amps, it has to be set with caution since the battery current input has limited accuracy. If it is too low, the threshold may never be reached. The threshold should be at least twice as large as the jitter on the battery current input. If this limitation forces the threshold to be set higher than desired, the BCT Duration can be increased slightly to compensate.

6.4.8.4 Peukert Number

This number can be entered in two ways. If the Supervisor has a Peukert number from the battery manufacturer, then it can be entered as a simple, one step numeric entry.

NOTE: The Peukert number relates to the internal resistance of a battery and provides an

indication (inversely) of the expected capacity; that is, a lower number is better.

If the Supervisor does not have a Peukert number, it must be calculated. This multi-step process involves entering four numbers derived from battery manufacturer’s specifications. Resulting Peukert number should be above 1.000 and below 2.000.

Figure 35–Battery Properties and Peukert Calculator windows

Peukert Calculator

To calculate the Peukert number the Supervisor must enter unique values for Peukert Time 1 and Peukert Time 2 and the corresponding discharge current for each. This information is taken from the battery specification sheet. Typically, time values of two hours and twenty hours provide the necessary data for the Peukert number calculation.

Equations (from actual customer configurations)

Alpha Technologies Ltd. 034-136-C0 Rev B WC

Refer to the back of this manual for Factory Service and Technical Support contact information

Example 1: Add More Rectifiers Alarm

The function of the following equation is to activate a custom alarm when load increases to a point where redundancy is compromised, but before any rectifiers go into power limit.

Enter the equation taking into consideration logic operators and the number and type of brackets used:

[Load Current] > ((([# Acquired Rectifiers]-1)*55)-5.5)

Where 1 is the number of redundant rectifiers, 55 is the max output current of a single rectifier before going into power limit (3kW PFM in this case), and 5.5 is the number of excess amps in the system required for battery float charging, LVD coils or anything that draws current from the rectifiers that is not the load.

Example 2: Generator ON/OFF Control

The function of the following equations will establish a pair of custom alarms that will activate one relay to start a secondary generator and another relay that stops the generator.

2a) Custom Alarm A to start a secondary generator:

( (V2 <= 46) & (D8 = 0) & (D7 = 0) ) | (V2 < 44.5)

When battery is discharged (system voltage (V2) is less than 46V) and primary (D7) and secondary (D8) generators are not on, OR system voltage is very low, activate. This alarm is exclusively mapped to a relay that is used to start the secondary generator.

2b) Custom Alarm B to stop a secondary generator:

( ( I2 <= 6 ) & (V2 > 53) & ( D8=1) ) | ( D7= 1)

When battery is charged (battery current (I2) is low and system voltage (V2) is near normal) OR primary (D7) generator is on, activate. This alarm is exclusively mapped to a relay that is used to stop the secondary generator.

Example 3: AC Voltage Reading in Mixed Rectifier Systems

The following scenario involves a CXC controlling Pathfinder 10kW rectifiers and Cordex 3.6kW rectifiers in a system with 277Vac. The CXC will compute the average AC reading of all rectifiers (for the AC MAINS HIGH/LOW alarms). In a PFM-CXR system, it may be desirable to have a separate AC alarm for each rectifier type.

To create separate alarms, first use the rectifier Phase Mapping feature (6.3.4) to assign each group of rectifiers to a different phase.

NOTE: the three individual phase voltages will no longer apply; instead, the average of

the AC input voltage on each system would be given.

Next, disable the regular AC alarms (6.5.3.5).

Finally, create custom alarms using the average phase voltages. Here is one possible equation:

([Average AC Phase R] < 240) | ([Average AC Phase R] > 300)

Scheduler Usage

The controller has basic scheduling capability that is implemented by using a System Time or System Date signal in any customizable equation; used to trigger external events on a timely basis, whether daily or at a specific date.

This is accomplished by using the System Time or System Date signal as an operator in a Custom Alarm equation, which has been configured to change the state of a relay output. The equation can include any other signals such as battery current or voltage for more advanced control. The System Time or System Date signal can only be used with the following operators: >, <, and =.

NOTE: the formats used for the Time and Date Operands are very specific and must

match exactly in order for an equation to be valid. For the System Time the format is <hh.mm.ss>> and for System Date the format is <<20YY.MM.DD>>. The '20' prefix for the year is what distinguishes the date from the time so it must not be omitted when entering a Date Operand.

Example 1: The following equation in a Custom Alarm will cause the alarm to be true for ten seconds (10s) at 2:35AM:

[System Time (HH.MM.SS)] > <<02.35.00>> & [System Time (HH.MM.SS)] < <<02.35.10>>

If the alarm is mapped to a relay, the relay will activate for 10s.

Example 2: Another example activates the alarm daily at 23:59:45 and clears when the battery voltage is less than 46V. This is the equation for the alarm named Custom 2:

(([System Time (HH.MM.SS)] > <<23.59.45>>) | ([Custom 2] > 0)) & ([Battery Voltage] > 46)

Note the term: ([Custom 2] > 0). This is to latch the alarm ON since the term: ([System Time (HH.MM.SS)] > <<23.59.45>>) will evaluate to false once the midnight rollover* (<<00.00.00>>) happens.

*Midnight Rollover is described with an example under Custom Signals.

Example 3: We can use the previous example along with a Counter to set the alarm to activate every three days. These are the equations for Counter 1:

Count Event "[System Time (HH.MM.SS)] > <<01.00.00>>" Reset Event "[Counter 1]>2"

The will cause Counter 1 to count once daily at 01.00.00. When the count gets to three, it is immediately reset back to zero. So, every third day, the count returns to zero.

Our Custom 2 alarm equation can now be:

(([System Time (HH.MM.SS)] > <<23.59.45>>) | ([Custom 2] > 0)) & ([Battery Voltage] > 46) & ([Counter 1] = 0)

The resulting behavior will be similar to that in Example 2, except the alarm will only activate once every 3 days.

This menu item enables the Supervisor to set the total number of converter fail alarms that will trigger the CXC’s converter minor alarm. The activation value must be less than or equal to the number entered for the major converter fail count alarm.

Conv. Out of Tolerance

This menu item enables the Supervisor to set an alarm condition when a converter out of tolerance is detected. The activation value is factory set.

Conv. Comms Lost

This menu item enables the Supervisor to set an alarm condition when converter communications is lost. The activation value is factory set.

Conv. Input Voltage Fail

This menu item enables the Supervisor to set an alarm condition when a converter input voltage fail is detected. The activation value is factory set.

The activation value for Input Voltage Fail detection is determined to be when the number of converters in Input Voltage Fail divided by the number of converters acquired is greater than or equal to 90%.

Conv. Fan Fail

The purpose of this feature is to enable the CXC to trigger the alarm when a fan fail (speed error or failed fan) condition has occurred in any of the converters in the system.

 The Fan Fail Alarm is true when the CXC receives a Fan Fail or Fan Speed Error alarm from any

converter.

 The Fan Fail Alarm is cleared when all Fan Fail and Fan Speed Error alarms are cleared from all

the converters.

 Each time that the Fan Fail Alarm goes on/off, the “event” is logged in the Event History. Since it

is a converter alarm, up to nine converters (up to 27 fan fail alarms) that are in alarm will be logged. If more than nine converters are in alarm an additional entry will be made indicating the total number of converters in alarm.

The activation value is factory set.

Conv. Load Current High

This menu item enables the Supervisor to program the setting for the converter load amps alarm. When the current to the load has exceeded this setting, an alarm is activated and the message CONV. LOAD CURRENT HIGH is displayed on the GUI.

Conv. Low Output Voltage

When the converter’s output voltage falls below the Supervisor-specified value, the alarm is activated and the message CONV. LOW OUTPUT VOLTAGE is displayed on the GUI.

Conv. High Output Voltage

When the converter’s output voltage exceeds the Supervisor-specified value, the alarm is activated and the message CONV. HIGH OUTPUT VOLTAGE is displayed on the GUI.

6.5.4 ADIO Alarms Detail

6.5.4.1 View Details

This menu item enables the user to select an ADIO device (i.e., Cordex Smart Peripheral) that is connected to the CXC and view the alarms with respect to: Cell Deviation, Current, Voltage, Temperature, and Comms.

6.5.5 Alarm Hysteresis

6.5.5.1 Voltage

Voltage Hysteresis applies only to Voltage Alarms (6.5.3.5). This value is the voltage range where the alarm can clear or activate. For example, if the low voltage alarm activates at 43.00V, having a voltage hysteresis of 0.50V means it will clear when the voltage reaches 43.50V.

6.5.5.2 Time

Time Hysteresis is the amount of time in seconds that the condition has to be true before the alarm is enunciated. In the example above, if the value of time hysteresis is 5 seconds, the voltage must be below 43.00V for at least 5 seconds before the alarm is activated. Similarly, to clear the alarm, the voltage must be above 43.50V for 5 seconds.

This feature is used only for the following:

 Current, Voltage, Battery, and Temperature alarms  HVSD and CEMF controls.

Example Five – Midpoint Voltage Error

The following is an example of a Custom Signal configured for an analog input (GP4) reading the midpoint voltage of the battery (or system). A Custom Alarm is then configured to track the signal deviations.

For the Custom Signal equation, the midpoint voltage of the battery (from GP4) is doubled and then subtracted from the total voltage reading provided by the Battery Voltage signal. An absolute value yields a positive integer.

6.6.2.7 Midnight Rollover

The Scheduler (see Scheduler Usage and Custom Alarm examples above) functionality is simple. It tests to see if the System Time is greater than the time entered by the user. This means that at midnight, 00.00.00, the user time will always be greater than the System Time.

Example

So how can the scheduler be set up to ensure that this midnight rollover will not cause a problem with any Custom Signal that uses the System Time? In real life, you might want to trigger a generator and keep it on for some amount of time regardless of the midnight rollover.

These sample equations will configure Custom Signal 1 to remain on for about 30s even if midnight rollover occurs.

Visit the Alpha website at www.alpha.ca for the latest manual and product downloads

For the Custom Alarm equation, the Custom Signal is compared to the maximum* allowable voltage deviation in battery string halves. In this example a message is recorded when the midpoint voltage is in error.

* Some fine-tuning may be required to obtain the ideal setting that is sensitive enough to detect a ‘bad’ cell and will not produce false alarms.

(configure custom alarm for input reading error)

Custom Signal 1 Equation:

([System Time (HH.MM.SS)] > <<23.59.55>> | [Custom Signal 1]) & ([Timer 1] < 29)

Timer 1 Equations:

Run Event: [System Time (HH.MM.SS)] > <<23.59.55>> Stop Event: [Timer 1] >30

By this example, we see Custom Signal 1 go to 1.00 at 5 seconds to midnight, then go to 0.00 at about 25 seconds after midnight. This behavior will repeat daily.

6.6.2.8 Converter Signals

This feature will enable the user to view the status for all of the acquired converters in the system; including but not limited to:

Total Conv. Current # Failed Conv. # Conv. Input Voltage Failed # Conv. Fan Failed Avg Conv. Output Voltage # Conv. Minor Alarm # Out Of Tolerance Conv. Converter Load Voltage Total Conv. Input Current # Conv. In Comms Lost # Conv. In Current Limit Converter Load Current # Acquired Conv.

The existing Controller Signals category now includes signals for Converter Load Voltage and Converter Load Current; by default, Average Conv. Output Voltage and Total Conv. Output Current are used respectively.

Re-configurable System Load Current and System Battery Voltage

For converter shelves that do not have any Cordex rectifiers in the system, the system Load Current may be re-configured to display the total converter output current and the system Battery Voltage may be re-configured to display converter output voltage; that is, the signals can be renamed.

Recommendation For Converter Redundancy

A redundant converter in a system will allow one converter to be shut down while the other converters supply power to the load; e.g., during firmware upgrade.

Summary: The Counter feature allows the tracking of event occurrences for any signal that the controller software is able to monitor as an equation. Any signal that is viewable through the equation builder is available.

Enable: Check the Enable checkbox to activate the counter. Line Value: Current count value. The reset button will set the value to 0. Count Event: The Count Event is an equation entry indicating the condition to count. This equation is

used to detect transitions. For example, if the equation is set to [AC Main] > 24, the counter will trigger when the voltage moves from 24 volts or less to above 24 volts.

Reset Event: The Reset Event is the trigger condition that sets the Count value back to 0. General Note: The Timer and Counter values themselves can be used in equations. They can monitor

each other.

DDDD:HH:MM:SS, which means 4 digits for days, 2 digits for hours, minutes, and seconds.

Line Value: Current time value for the timer. Run Event: Trigger equation indicating a timer start. Stop Event: Trigger equation indicating a timer stop. Note (Run/Stop): The Run Event acts as a level detector if the Stop Event is left empty. With a set Stop

Event, the Run Event acts as an edge detector where a transition will cause the timer to start, but the same event in the reverse direction will not cause the timer to stop. This allows the Run and stop events to be completely separate and unrelated events. General Note: The Timer and Counter values themselves can be used in equations. They can monitor each other.

NOTE: There are three possible triggers for opening the LVD, one of which is that loss of AC mains immediately starts

the activation timer, if it is enabled, and the LVD will open at the timeout point.

DOD Activation — For LVD control, tap on the number (percentage of DOD) to edit via a virtual numeric keypad.

Disconnect Voltage, Connect Voltage — for each LVD (1-10), tap on the number(s) to edit via a virtual numeric

keypad.

Inhibit Status — For LVD Inhibit, select from the pull-down menu; e.g., Inactive or Active. Selection will be in effect real-time and not saved.

Activation Value — For HVSD, tap on the number to edit via a virtual numeric keypad.

Bypass Voltage, In-Circuit Voltage — For CEMF, tap on the number(s) to edit via a virtual numeric keypad.

6.7.1 LVD Control (USE WITH CAUTION)

The LVD feature controls a high capacity relay that disconnects the load during extremely low voltage conditions — such as a deep discharge of the batteries during an AC fail — and automatically reconnects the load once AC power returns. Discharging the battery down to an extremely low voltage can cause damage to the load and the battery. Having multiple LVDs will provide the capability of load shedding; where the least critical loads are disconnected first.

With the CXC, the Supervisor can program connect/disconnect settings to govern the operation of ten separate LVD controls. The LVD is activated when the Activation Voltage or the Activation Time is reached; whichever comes first. The LVD also extends an alarm signal and a message will display on the GUI.

Under this window of operation, there is a list of menu items (tap to select) with scroll bars for navigation, see Figure 80 below:

6.7.1.1 DOD Activation

This menu item (LVD DOD Control) allows the Supervisor to configure each LVD control for activation once the percentage of Depth of Discharge (DOD) has increased above a threshold. This control works in conjunction with the existing LVD countdown timer and the disconnect voltage. Whichever programmable parameter is met first, the LVD will be activated. Typically, LVD DOD control is needed when ac mains fails, battery monitor is enabled, battery has discharged for more than one (1) minute and DOD has risen above the threshold. If DOD activates LVD, then the low voltage connect (LVC) causes reconnect.

6.7.2 LVD Inhibit

The LVD Inhibit feature provides the means to temporarily prevent all LVD controls from activating without disabling the LVDs altogether, see example below. The Supervisor will then have 10 minutes to assess and correct the condition(s) causing the LVD activation.

This menu item differs from other controls in that it cannot be disabled; “Enable Alarm” is grayed out. With that exception, the remainder of the configuration is similar to all other controls (relay mapping, etc.), see Figure 81 above. It is logged in an identical manner, except that the only possibilities are ACTIVE and INACTIVE. Selection will be in effect real-time and not saved – resets on power off.

Operation Example:

1. LVD condition occurs.

2. Audible alert sounds and a pop-up window will appear on the GUI prompting the user

3. For up to 60 seconds, LVD Inhibit may be evoked by the Supervisor. A password

activating for 10 minutes.

6.7.3 HVSD

This menu item enables the Supervisor to program the setting for a HVSD control, which energizes a relay that can shut down one or more rectifiers when the output voltage exceeds the Activation Value. The output from HVSD relay is connected to the Remote Shutdown input on the rectifier cabinet. An alarm is also activated and the message HIGH VOLTAGE SHUTDOWN will display on the CXC’s GUI.

6.7.4 CEMF

The CEMF Cell is a stand-alone panel; which is used to reduce the load voltage (by up to 3.0Vdc) to protect sensitive loads from high voltages during battery equalize and float cycles.

6.7.4.1 Bypass Voltage

6.7.4.2 In-Circuit Voltage

This menu item enables the Supervisor to set the voltage breakpoint to close the CEMF relay and bypass the CEMF cell (or diode); to directly connect the load to the rectifiers without voltage drops.

This menu item enables the Supervisor to set the voltage breakpoint to open the CEMF relay and connect the CEMF cell (or diode); to give the appropriate voltage drop to protect the load connected to the rectifiers.

6.8.3.1 CXCI IP Address Reset and Startup

This feature enables the user to reset the IP address of the CXCI. It is a function of the front panel reset button on Cordex controllers that have only a 4-digit display.

The reset button located on the front panel of the CXCI is for restarting the microprocessor. When pressed momentarily, the unit beeps twice then resets. The front-panel LED’s will illuminate temporarily, but will extinguish after the system has finished its 15-second self-test.

To reset the IP address, press and hold the front panel reset button for three seconds. The unit will beep three times, IP will be reset (to 10.10.10.201) and DHCP (see 8.1.1.5) will be disabled. The settings will be saved and the unit will then reset.

There is also a “hard” reset button located on the side of the CXCI. Pressing this button will reset the CXC but will not affect any settings; has the same functionality as the reset button on a CXC with a touch screen LCD.

The CXCI, upon startup

, will set the time based on the following priorities:

1. Attempt to synchronize with the NTP server (see www.NTP.org), otherwise:

2. Retrieve the last time stamp from the Event Log, otherwise:

3. Retrieve the last time stamp from the Statistics Log, otherwise:

4. Set the time to 2005-01-01 midnight (if the above methods fail).
