Relay will energise “ON” when Flush condition is in effect
and goes off when Flush condition is cleared. A relay being
used for Flush Valve/Pump must be assigned to one of the
main pumps in use. Flush relay Alarm ID (P212, 222, 232,
242, 252, 262) is used to enter the relay number, to which
the assigned pump is connected.
Flush Valve/Pump relay requires three setpoints. The first set
point (P213, 223, 233, 243, 253, 263) determines the Flush
Interval, which is the number of main pump cycles that
should occur before the Flush Valve/Pump operates. The
second setpoint (P214, 224, 234, 244, 254, 264), sets the
number of Flush cycles the Flush Valve/Pump will operate
for. This means that the Flush Valve will be operated for
several main pump starts (Flush Cycles) after which the Flush
Valve activity will cease until the Flush Interval comes
around again. Setpoint three of the Flush Valve/Pump relay
sets the Flush Duration, (P215, 225, 235, 245, 235, 236) this
is the duration for Flush
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 Step 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). Alarm ID (P212, 222, 232, 242, 252, 262)
is used to assign the relay to control either the open or close
condition. Step Time Control relay requires three setpoints.
The first set point (P213, 223, 233, 243, 253, 263) determines
the level, at which the relay is to be activated, (N.B. level
setpoint for open relay, increase the level, must be lower
than the setpoint for the close relay, decrease the level). The
relay will energise “ON” after the Limit time that is set in
Relay Setpoint 3 (P215, 225, 235, 245, 255, 265). And turns
“OFF”, de-energises, after the Drive Period that is set in
Relay Setpoint 2 (P214, 224, 234, 244, 254, 264).
