Miscellaneous
P2n0 = 4 (Miscellaneous)
When a relay is set to be a miscellaneous relay, the second parameter
determines its function.
P2n1 – 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 (P2n3). And turns OFF, de-energises,
after the specified-On Time period as set in Relay
Setpoint 2 (P2n4)
When Ultra
Wizard = 3 Flow
2 = Totaliser
Relay will energise ON momentarily each time the
specified flow has passed as set in Relay setpoint 1
(P2n3), 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 (P2n4) is
used to select the time the relay will remain closed in
seconds.
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
(P2n1) for further information.
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.
