The previous table outlines the various alarms that are available through the QS840A controller. Refer
to Alarm Relays in Appendix C for more details. The QS840A controller is provided with two severity
relays and two relays that may be assigned to any combination or all of the alarms noted above.
The controller is shipped with PMN assigned to Alarm Relay 2 and PMJ to Alarm Relay 1. Also, for each
alarm condition noted above, the factory severity is noted in bold. The user may change the severity of
configurable alarms from the factory set severity. Note that the alarms noted above may also be
assigned a severity of RO (Record Only). If so assigned, the alarm condition will be transmitted without
any PMJ or PMN severity.
The following is a brief explanation of the alarm conditions.
Battery on Discharge: The battery on discharge alarm is asserted when the controller detects the plant
bus voltage going below the Battery on Discharge thresholds set by the user.
High Voltage: The high voltage alarm is asserted when the controller detects the plant bus voltage
going above the High Voltage thresholds set by the user.
