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