In this case, the message indicates that there are three alarms present and they can be observed by pressing the ENTER
button.
When the ENTER button is pressed the most recent alarm name, such as the one shown below will appear on the display.
Alarm 1
Amb Temp High
If no button is pressed again for one minute, the display will revert to the “home” screen and the sequence begins again.
To view the remaining alarms, use INC and DEC buttons. Pressing the ENTER button will return the display to the “home”
screen. The time and date of any given alarm can be obtained by entering the ALARM LOG menu.

Controller Alarms
A list of all the possible alarms that can be enunciated is shown in the following table.
Alarm Name
Comments
LED
RECTIFIER Alarm
Combination of one or more RECTIFIER alarms
A
RECTIFIER Urgent
One or more RECTIFIERs have shut down
A+R
RECTIFIER HVSD
RECTIFIER shut down due to output over-voltage
A+R
UNIT OFF
RECTIFIER is off
A+R
No Response
A particular RECTIFIER is not responding to the Controller
A
Power Limit
RECTIFIER is in Power Limit
A
No Load
RECTIFIER output current less than minimum for RECTIFIER type used
A
Current Limit
RECTIFIER in current limit
A
Voltage High
Voltage measured by RECTIFIER too high
A
Voltage Low
Voltage measured by RECTIFIER too low
A
UNCAL RECTIFIER
RECTIFIER Internal Adjustment for current sharing out of limits
A
EEPROM Fail
EEPROM failed (CSU or RECTIFIER)
A
Fan Fail
RECTIFIER Internal Fan failure alarm
A
Relay Fail
RECTIFIER output relay contact failure
A
No Demand
Control loop in RECTIFIER not in normal state
A
H/S Temp High
RECTIFIER heatsink temperature too high (where available)
A
Temp Sensor Fail
Temp sensor in RECTIFIER faulty - S/C or O/C (where available)
A+R
Vref Fail
Voltage reference in RECTIFIER microprocessor circuit faulty
A+R
HVDC not OK
DC/DC converter (boost) voltage in RECTIFIER not OK
A+R
AC Volt Fault – detected by
RECTIFIERs
All RECTIFIERs are reporting AC fault. Available only on some RECTIFIER
models.
A+R
AC Volt Fault – detected by
Controller
None of RECTIFIERS are responding (AC fail assumed), or if AC monitor is
used, AC voltage is out of limits set
(When no AC monitoring module is used, this comes together with
“RECTIFIER Comms Fault”)
A
AC Freq Fault
AC frequency lower or higher than preset value
A
Battery Switch
One or more battery switches open
A
Cct Breaker
Fuse or CB in load distribution open
A
LVDS Open
Low Voltage Disconnect switch open
A
Sys Volts High
System output volts too high
A
Sys Volts Low
System output volts too low
A
System V Clamp
CSU cannot reach desired system voltage. This can be due to possible excessive
voltage drop along bus bars or “System V Drop” parameter has value too low.
A
Cell V High
One or more cells being monitored by BCM is too high in voltage
A
Cell V Low
One or more cells being monitored by BCM is too low in voltage
A
Cell %dev High
One or more cells being monitored by BCM is too high % deviation from the
mean battery cell voltage
A
Cell %dev Low
One or more cells being monitored by BCM is too low % deviation from the
mean battery cell voltage
A
Range RECTIFIER
RECTIFIER parameter range error. Controller could not overwrite values
A
Site Monitor
Alarm present from the site monitor module. See site monitor menu for details
of alarm channel.
