The fourth parameter and the fifth parameter for each relay set the pump
“
ON
” and “
OFF
” points, which are entered in
Measurement units P104 .
For pump down
the “
ON
” is set
higher than
“
OFF
”. For
pump up then
“
ON
” is set
lower than
“
OFF
”. See the appropriate
pump duty, function
table ( P212, 222, 232, 242, 252 ) for further information.
P213, P223, P233, P243, P253 - Relay Setpoint 1
This parameter determines the “
ON
” point of the pump.
P214, P224, P234, P244, P254 - Relay Setpoint 2
This parameter determines the “
OFF
” point for the pump.
The sixth parameter will determine the service ratio that will be used to
switch the pump, when pump duty selected is a Service Ratio duty.
P211, 221, 231, 241, 251 = 6, 7 or 9 (Service ratio)
P215, P225, P235, P245, P255 - Relay Setpoint 3
This parameter determines the Service Ratio in values of %. See the
appropriate
pump duty function, table ( P211, 221, 231, 241, 251 ), for
further information.
P219, P229, P239, P249, P259 - Relay Max.Rate
This parameter will allow a pump to be switched at a pre-determined Rate
of change of Level
, irrespective of the “ON” level setpoint P213, 223, 233,
243, 253. Once a pump relay has been switched “ ON
” by the pre-
determined Rate of Change , it will remain energised until the level reaches
the “
OFF
” level setpoint
P214, 224, 234, 244, 254 .
Max. Rate is entered in Measurement Units (P104) per minute and can be
entered as either positive (increasing level) or negative (decreasing level)
values.
