P*219, P*229, P*239, P*249, P*259, P*269 - 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 P*213, 223, 233,
243, 253, 263. Once a General Control relay has been switched “ON” by the
pre-determined Rate of Change, it will remain energised until the level
reaches the “OFF” level setpoint P*214, 224, 234, 244, 254, 264.
Max. Rate is entered in Measurement Units (P*104) per minute and can be
entered as either positive (increasing level) or negative (decreasing level)
values.
Control
P1 and P2
When P*210, 220, 230, 240, 250, 260 = 3 (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.
P*211, P*221, P*231, P*241, P*251, P*261 Relay Function,
This function allows the relay to be assigned to specific control functions
(other than pumps and alarms) several of these functions work in relation to
time.
This can be used to activate devices based on elapsed time or running
cycles, such as a timed rake control to keep a ram lubricated if idle for long
periods, or flush valve operation.
Relay will energise “ON” after the Cycle
time that is set in Relay Setpoint 2 (P*214,
224, 234, 244, 254, 264). And turns “OFF”,
de-energises, after the On Time Period that
is set in Relay Setpoint 1 (P*213, 223, 233,
243, 253, 263)
