Important Information
When using a Relay to control a device at a specified time of day ensure that
the Time P932 is set correctly. And if required, enable Daylight Saving for
the appropriate time difference P970 – P979.

The third parameter has no function when miscellaneous relay is chosen
and will not be displayed.
The fourth parameter, and fifth parameter, are set to determine the switch
points, “ON” and “OFF” for the relay. See miscellaneous function table
(P211, 221, 231, 241, 251) for further information.
P211, 221, 231, 241, 251 = 1 (Clock)
P213, P223, P233, P243, P253 - Relay Setpoint 1
Relay Setpoints are entered in Hours & Minutes (HH:MM) to set Time at which
relay will energise. Default = 00:00 (HH:MM)
P214, P224, P234, P244, P254 - Relay Setpoint 2
Relay Setpoints are entered in Minutes to set Time Period that the relay will
remain ON. Default = 0.00 mins.
P211, 221, 231, 241, 251 = 2 (Totaliser)
P213, P223, P233, P243, P253 - Relay Setpoint 1
Relay Setpoints are entered as a factor by which the on board totaliser (P820)
should be multiplied by to provide a relay closure. Default = 0.00
P214), P224, P234, P244, P254 - Relay Setpoint 2
Relay Setpoints are entered in seconds to set the time period that the relay will
remain ‘ON’. Default = 0.00 secs.
P219, P229, P239, P249, P259 - Relay Max.Rate
This parameter will allow a pump to be switched at a pre-determined Rate
of change of Level, irrespective of the “ON” level setpoint P213, 223, 233,
243, 253. Once a General Control relay has been switched “ON” by the predetermined
Rate of Change, it will remain energised until the level reaches
the “OFF” level setpoint P214, 224, 234, 244, 254.
Max. Rate is entered in Measurement Units (P104) per minute and can be
entered as either positive (increasing level) or negative (decreasing level)
values.
