The Password 2000 will be required to make changes in this section.
There are four relays available.
Relay 1 (R1) is set as General purpose use for Oil alarm setpoints (factory default), valve control, etc.
Relay 2 (R2) is set as an Air alarm (factory default). An air alarm may occur when the sensor is out
of the water due to maintenance, no water in sump or obstruction of float sensor from floating
properly in the water. To disable the factory default setting for relay 2 to act as Oil Alarm, press
“Enabled Relay 2 as Air Alarm relay”
.
Relay 3 (R3) is set as a Fault (factory default). A fault alarm may occur when there is no signal from
sensor to main contoller. To disable the factory default setting for relays 3 as Fault, press
“Enabled
Relay 3 as fault relay”
.
Relay 4 (R4) is set as Oil Alarm (factory default). Relay 4 can be set as (1) Pump Run relay with a
timed and auto shut-off feature or (2) Level sensor. The pump run relay that initiates a pump at a
prescribed % level of oil and then runs for a determined amount of time. The relay will deactivate
the pump after the run time or when the oil level returns to pump reset level on the sensor,
whichever occurs first. The purpose of the run time feature is to allow a pump to run based on a
desired volume evacuation of oil without running dry or pumping water out. To disable the factory
default setting for relay 4 to act as Pump run or Level sensor, press config button then select which
feature for relay 4.
Relay 4 set as a Pump Run relay option,.
