Pumps
When P210, 220, 230, 240, 250 = 2 (Pump)
When a relay is being used for a pump function, the second parameter
determines the pump duty that will be used to determine the operating
cycle.
P211, P221, P231, P241, P251 - Relay Function,
This parameter defines which pump duty the relay should respond to as
follows.
Pump Duty
Description
0= Off (Default)
Relay is always de-energised.
1= Fixed duty assist
All pumps are used to assist each other
(run at the same time) and each pump
has its own setpoints. (P213, 223, 233,
243, 253 & P214, 224, 234, 244, 254).
2= Fixed duty backup
If a pump fails to meet the demand (due
to malfunction, intake blockage etc.),
then it is stopped and another pump shall
take over. Each pump has its own
setpoints. (P213, 223, 233, 243, 253 &
P214, 224, 234, 244, 254).
3= Alternate duty assist
All pumps are used to assist each other
(run at the same time). Each pump has
its own setpoints, (P213, 223, 233, 243,
253 & P214, 224, 234, 244, 254) but
each time all pumps have stopped, the
setpoints are sequentially rotated
between the pumps to ensure equal
pump use.
4= Alternate duty backup
If a pump fails to meet the demand (due
to malfunction, intake blockage etc.),
then it is stopped and another pump shall
take over. Each pump has its own
setpoints, (P213, 223, 233, 243, 253 &
P214, 224, 234, 244, 254) but each time
all pumps have stopped, then the
setpoints are sequentially rotated
between the pumps to ensure equal
pump use.
