Control
P*210, 220, 230, 240, 250, 260 = 3 (Control)
When a relay is being set as a
control
relay, the second parameter that will
be displayed in the menu determines its
function
.
P*211, P221, P231, 241, 251, 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.

5 = Step Time
Step Time Control allows relays to be used to control a
device, such as a motorised valve or gate, in order to
maintain the level within two predetermined points. Relays
will
energise
“
ON
” when Step Time condition is in effect and
de-energises
“
OFF
” when S
tep Time goes off. One relay will
be required to control an increase in level, (‘open’ the device)
and a second relay is required to control a decrease in level,
(‘close’ the device).
