This controller can perform control functions for most Dual Pump pumping applications. It is more than likely that the
control parameters have already been set up for your particular application however; hereunder you will find details of
the set up and configuration options.
There are 6 DIP switches located on the lower side of the control module, which allow s for selecting “mode” and
“feature” options, as per the following table:

High Level alarm Automatically resets upon open circuit of high level input.
High level alarm has 15 Minute delay.
On
High level alarm can only be reset Manually . High level alarm has 5 minute
delay.
Mode A: Standard configuration
Start/Stop/High level operation. When the pump start input is closed contact (triggered), the duty pump will be
Standard typical float switch configuration (Start, Stop and High Level).
No low level.
Standard configuration plus low level (Start, Stop, High level and Low
level).
Standard configuration plus Prime Loss enabled, on Low level (Input 1)
Pressure Pumping configuration (Lead, Lag and Low pressure)
Operating pump alternates after 6 hours continuous running
Operating pump alternates each time a pump start is triggered, or after 30
minutes continuous running.
turned on. The pump will remain on until both the pump start and pump stop inputs have turned off (open circuited).
Upon high level both pumps will run until the pump stop input turns off.
In addition to this, there is a maximum idle timer, which will trigger a pump start condition, if either pump has not
run for 4 hours, and the stop float contacts are closed. The pump will continue to run until the stop float contacts open.
Input functions are as follows:
Mode B: Standard Configuration plus Low Level Alarm
As per Mode A, except it has an active Low Level input. The low level input must be closed, for pump start and pump
stop inputs to function. The High level input however, will still override the low level and run both pumps.
Input functions are as follows:
The basic logic on which a High or Low Level Alarm is determined, is set out in the Table A.
