Relay will energise “ON” when a differential condition is in
effect and, de-energise “OFF” when the differential
conditions cease. Two setpoints are required, Differential
control “ON”, (P213, 223, 233, 243, 253, 263) and
Differential control, “OFF” (P214, 224, 234, 244, 254, 264).
This allows the relay to be used to activate a device because
of a differential level, between two points e.g. operate a rake
on a screen.
The third parameter for each relay determines the assignment or
condition of the relay, where required.
P212, P222, P232, P242, P252, 262 - Relay Alarm ID/Pump Group,
P211, 221, 231, 241, 251, 261 = 1, 2, 3 or 6
This parameter has no function and will not be displayed.
P211, 221, 231, 241, 251, 261 = 4 (Flush Valve)
If the relay is selected for Flush Valve/Pump, then this parameter is used to
determine to which pump the Flush function is assigned. Enter the relay
number to which the assigned pump is connected.
P211, 221, 231, 241, 251, 261 = 5 (Step Time)
If the relay is selected for Step Time, then this parameter is used to assign
the relay to the 0 = Open condition (increase level) or 1 = Close condition
(decrease level).
The fourth parameter, fifth parameter and sixth parameter are set to
determine the switch points, “ON” and “OFF” for the relay and where
required the order of start. See control function, table (P211, 221, 231) for
further information.
P213, P223, P233, P243, P253 Relay Setpoint 1
P211, 221, 231, 241, 251, 261 =1 (Time)
This parameter determines the “Time Period” that the relay will remain “ON”.
Relay Setpoints are entered in Minutes.
See the appropriate relay Function tables (P211, 221, 231, 241, 251, 261)
for further information.
