Relay will energise “ON” after each Cycle
time as set in Relay Setpoint 2 (P214, 224,
234, 244, 254). And turns “OFF”, de-
energises, after the set On Time Period as
set in Relay Setpoint 1 (P213, 223, 233,
243,253).
This can be used to activate a device based
upon elapsed time since All Pumps have been
“OFF”, such as the introduction of fresh air to
reduce gas concentration.
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) 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) 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), sets the number of
Flush cycles the Flush Valve/Pump will
operate for. This means that the Flush Valve
will be operated for a number of 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) this is
the duration for Flush Cycle, in seconds.
