P214, P224, P234, 244, 254 - Relay Setpoint 2
This parameter determines the “
OFF
” point for the general control relay, the
Relay Setpoints are entered in values of Measurement Units (P104)
P219, P229, P239, 249, 259 - Relay Max.Rate
This parameter will allow a
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 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.
Pumps
When Ultra Wizard = 2 Pump/Differential or 3 Flow
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. (P2

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. (P2
