Miscellaneous
P1 and P2
When P*210, 220, 230, 240, 250, 260 = 4 (Miscellaneous)
When a relay is set to be a miscellaneous relay, the second parameter
determines its function.
P*211, P*221, P*231, P*241, P*251, P*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 will energise ON at a specified time each
day as set in Relay Setpoint 1 (P*213, 223, 233,
243, 253, 263). And turns OFF, de-energises,
after the specified On Time period as set in Relay
Setpoint 2 (P*214, 224, 234, 244, 254, 264)
Relay will energise ON momentarily each time
the specified flow has passed as set in Relay
setpoint 1 (P*213, 223, 233, 243, 253, 263) this
parameter sets the multiplication factor which
will be applied to the on board totaliser (P1-
820/P2-820) 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 (P*214, 224,
234, 244, 254, 264) is used to select the time the
relay will remain closed in seconds.
Mode (P100) is set:
4 = (OCM Head)
Important Information
When using a Relay to control a device at a specified time of day ensure that
the Time P*932 is set correctly. And if required, enable Daylight Saving for
the appropriate time difference P*970 – P*979.
The third parameter has no function when miscellaneous relay is chosen
and will not be displayed.
