Target pressure for the pump system discharge
To change the set pressure to this alternate
value, a dry contact must close between G-COM
and 018 on the CN8 terminals.
If the discharge pressure exceeds this value, the
controller will shutdown the pumps after a delay.
If the discharge pressure drops below this value,
the contoller will shutdown the pumps after a
delay.
If the set pressure is 60 PSI and start lead
pressure at -3 PSI, the lead pump will start
when the operating pressure drops below 57 PSI.
If the set pressure is 60 PSI and start lag
pressure is -7 PSI the lag pump(s) will start when
if lead pump is operating full speed (100% and
the system pressure drops below 53 PSI.
If the set pressure is 60 PSI and the stop lag
pressure is 3 PSI the lag pump will stop if it is
operating at minimum speed (example 50%)
and the current pressure is over 63 PSI.

Sampling time of PID Control
Shifts the lead to the next available pump in the
sequence.
PSI offset allowance for friction loss
Delay time for pumping output to start
Delay time for pumping output to stop
Delay time after the main pump starts
Sets the operation type. VFD = multiple VFD
control system (1 VFD for each pump.)
1VFD+ATL = Single VFD control system
(combination of 1 VFD and starters)
Delay time before stipping the pump due to low
suction pressure
Method used to reset the low suction shut
down valve
When low scution rest is set to auto, this is the
time the controller will wait before attempting
to reset.
Delay time before stopping the pump due to low
pressure fault.
All parameters are set to factory defaults
