STANDBY
The STANDBY function allows for the pump to be stopped remotely. If a dry contact or open collector
signal is received to the STANDBY inputs, the pump will cease operation as long as the signal is
present. The pump will also flash “STANDBY” on the operating display.
NOTE: The STANDBY function can be used to transfer operation to a secondary pump in the event of a primary pump
failure. An output relay on the primary pump is programmed for TRANSFER and Normally Closed. This relay provides an
input to the STANDBY function of the secondary pump, which is programmed identically to the primary pump. In the
event of a loss of power or an alarm event that shuts down the primary pump, the output relay on the primary pump
opens and activates the secondary pump.
