Control
P210, 220, 230, 240, 250 = 3 (Control)
When a relay is being set up as a control relay, the second parameter that
will be displayed in the menu determines its function.
P211, P221, P231, P241, P251, Relay Function,
This function allows the relay to be assigned to specific control functions
(other than pumps and alarms) several of these functions work in relation to
time.
This can be used to activate devices based on elapsed time or running
cycles, such as a timed rake control to keep a ram lubricated if idle for long
periods, or flush valve operation.
Relay is always de-energised
Relay will energise “ON” after the Cycle
time that is set in Relay Setpoint 2 (P214,
224, 234, 244, 254). And turns “OFF”, de-
energises, after the On Time Period that is
set in Relay Setpoint 1 (P213, 223, 233, 243,
253)
When Ultra Wizard = 2 Pump/Differential
Relay will energise “ON” when storm
conditions are in effect and, de-energise
“OFF” when storm conditions cease. Two
setpoints are required, Upper Storm “ON”,
(P213, 223, 233, 243, 253) and Lower Storm,
“OFF” (P214, 224, 234, 244, 254).
This allows the relay to be used to activate a
device as a result of high levels such as a
storm condition e.g. opening a gate valve to
divert storm overflow into a holding vessel.
