Overfill Alarm Relay
The console has one dry contact relay output that closes when an overfill alarm is activated. You can connect an
external audible/visual warning device to this relay. Connect the two wires from the external warning device to the
either of the two overfill relay terminals (J5) [see Figure 23].
Important! Note these Output Relay Connection Restrictions:
• Output relays can not be connected to a device that draws more than 2 amperes of current.
• Output power - output relay contact, resistive load - 120/240 Vac, 2 A max.
Alarm relays cannot be used for flow control. Alarm relays provide only a momentary closure and cannot actuate
flow control devices such as valves and pump motor relays for extended periods of time.
