If the sequential start timer (SST) is required refer to
Appendix F. If not required set the SST to disabled. If
required, the lead pump SST should be set to disabled and
the lag SST to five (5) to ten (10) seconds. If there are more
than two pumps in the system, allow a ten (10) second
delay between pumps.
The acceleration timer (AT) is used for reduced in-rush
current controllers only. The AT will be factory set but will
automatically adjust depending on the starting method that
the controller is programmed to. If it is found that more
time is required to allow the pump to come up to speed,
the timer may be adjusted up to 10 seconds. Refer to
Appendix F for programming of the AT.
If the Undervoltage/Overvoltage alarms are present, check
the programmed values by referring to Appendix H. If the
values are programmed to their maximum and the alarms
continue to occur, check the main voltage supply to ensure
that the power available is dependable as per NFPA,
Pamphlet 20 standards.
