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.
When a relay is being used for a
pump by time
function, then the
sixth
parameter
will determine the maximum time the pump will be allowed to
run before it is switched off and the next pump takes over.
P215, P225, P235, P245, P255 - Relay Setpoint 3
This parameter determines the
Maximum Time
the pump will be allowed to
run
before being switched “
OFF
” and is entered in minutes.
The pump will switch off either at its “
OFF
” level
Relay Setpoint 2
(
P214,
224, 234, 244, 254
) or its
Maximum Run Time
Relay Setpoint 3
(
P215,
225, 235, 245, 255
), whichever occurs
first
.
P219, P229, P239, P249, P259 - Relay Max.Rate
This parameter will allow a
pump
or
general control relay
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 or general control 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.
