OPTIONS DESCRIPTION
6 = Differential
Control
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 ”, (P2 1 3, 2 2 3, 2 3 3, 2 4 3, 2 5 3, 2 6 3) and
Differential control, “ OFF ” (P2 1 4, 2 2 4, 2 3 4, 2 4 4, 2 5 4, 2 6 4).
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.
