Control
P210, P220 = 2 (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 - Relay Function,
This function is used, where it is required to
energise
the relay to switch a
device, such as a pump,
ON
and
de-energise
the relay to switch the device
OFF
.

Important Information
A control relay is started and stopped at the “ON” and “OFF” setpoints. To
control down
(reduce level) then set “ON” higher than “OFF”. To
control up
(increase level) then set “ON” lower than “OFF”. For relay 1 “ON” is P213,
“OFF” is P214 and for relay 2 “ON” is P223, “OFF” is P224
The
fourth parameter
, and
fifth parameter
, are set to determine the switch
points, “
ON
” and “
OFF
” for the relay. See
control function
, table (
P211,
221, 231
) for further information.
P213, P223 - Relay Setpoint 1
This parameter determines the “ON” point for the control relay.
Relay Setpoints are entered in values of Measurement Units (P802).
P214, P224 - Relay Setpoint 2
This parameter determines the “OFF” point for the control relay.
Relay Setpoints are entered in values of Measurement Units (P802).
