6.4 User programmable relay functions

All controllers with RTP standard software of version/revision 'fa' or higher support this
feature. Other customised software can include it as well. To check if your unit supports
programmable relays, perform Indicators Test as described in section 6.6.3.
New units have factory default relay assignment. For details refer to paragraph "Relay
Contact outputs" in User Interface sections of this manual.
158-1872-01
AC frequency lower or higher than preset value
One or more battery switches open
Fuse or CB in load distribution open
Low Voltage Disconnect switch open
System output volts too high
System output volts too low
MCSU-4 can not 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.
One or more cells being monitored by BCM is too high in voltage
One or more cells being monitored by BCM is too low in voltage
One or more cells being monitored by BCM is too high % deviation from
the mean battery cell voltage
One or more cells being monitored by BCM is too low % deviation from
the mean battery cell voltage
SMR parameter range error. MCSU-4 could not overwrite values
Alarm present from the site monitor module. See site monitor menu for
details of alarm channel.
Batteries are discharging
Battery discharge test failed to reach a programmed end point
Alarm flags only if the system voltage falls below Discharge Alarm level
while the battery is discharging
Alarm generated for NiCad batteries using special sensor and software
One or more of SMRs are not responding
Ambient temperature higher than preset limit
Battery temperature higher than preset limit
Battery temperature sensor not connected or failure
Battery charging current is being limited to preset value
Battery discharge currents from battery strings not sharing load equally
Earth leakage current greater than the limit set
System is in equalise mode
