Miscellaneous
P210, 220, 230, 240, 250 = 4 (Miscellaneous)
When a relay is set to be a miscellaneous relay, the second parameter
determines its function.
P211, 221, 231, 241, 251, 261 – Relay Function
This function allows the relay to work in relation to a clock or a specific event
and will be set to activate in relation to Real Time.
Relay is always de-energised
Relay will energise ON at a specified time each day as set
in Relay Setpoint 1 (P213, 223, 233, 243, 253, 263). And
turns OFF, de-energises, after the specified “On Time”
period as set in Relay Setpoint 2 (P214, 224, 234, 244,
254, 264)
Relay will energise ON momentarily each time the
specified flow has passed as set in Relay setpoint 1 (P213,
223, 233, 243, 253, 263), this parameter sets the
multiplication factor which will be applied to the on-
board totaliser (P820) to determine the switch point of
the relay. E.g., if the totaliser is set to totalise in cubic
metres and the relay is required to provide a closure
every 10,000 litres Relay setpoint 1 would be set to 10.
Relay setpoint 2 (P214, 224, 234, 244, 254, 264) can be
used to select the time the relay will remain closed in
seconds.
Important Notice
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.
