BASIC SETUPS:
Basic Setup screens need to be completed by factory and/or End User before operation.
To set Time, Date and Year – Touch SET, enter information and hit Accept or Cancel to exit.
Select Discharge or Flow and its corresponding Setpoint. Only one is selected as Control Type. Discharge/Flow
Setpoint is the system PSI/GPM at the output of the Booster that will be maintained. If flow required, presetup at
factory is necessary. Contact factory.
Select number of pumps to be operated by Controller. VFDs not set to Hand On or Off will continue to operate with
VFDs that are left in Auto On. Lost communication between a VFD and Controller will also continue to operate with
VFDs with an established communication and set to Auto On. VFD operation mode and communication are shown on
Home screen.
Pump Control Response to System Changes: Select High, Medium or Low for desired response for system demand.
High system demands (quick flow changes) may be set to High. Low system demands (low flow changes) may be set
to Low. Normal operations should be set to Medium.
STAGING (General description based on pressure or flow related to speed).
Lead pump is the first pump in the
system that is turned on. Other pumps that follow are Lag pumps. Lead pump will turn on when minimum PSI is not
met and Lead pump Time Delay is timed out. Staging on of the pumps once Lead pump is established is based on
Speed and PSI. If the Lag On Delay times out, additional pumps are turned on. If the speed is equal to or greater than
Set Start Speed and PSI remains below Setpoint, then next pump will turn on. If the Speed is minimum for greater
than the Lag Off Time Delay, first Lag pump on is turned off.
The minimum Lead pump and Lag pump Starting Speed are entered in the Advanced Settings screen at the factory.
The minimum Lead pump and Lag pump Stopping Speed is determined by pump curves and PLC calculations.
Lead and Lag pump operation and speed are set at recommended settings and should not be adjusted without
proper investigation.
LEAD PUMP SEQUENCE. First Pump On/First Pump Off.
In the default controller settings, the Lead pump is
changed during every start-up cycle or when more than one pump has been started in a single stage cycle. This
sequence will be First Pump On/First Pump Off. The first pump on or lead pump will rotate to the next pump in the
sequence if only one pump is cycled on and off. If more than one pump has been started, then the pump that started
second will be the new lead pump. The old lead pump will be the first pump off. The new lead pump will be last pump
on in new start-up cycle. The next lead pump will be the next pump in the sequence.
