This controller can perform control functions for most Dual Pump pumping applications. It is more than likely that the con-
trol 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 allows for selecting “mode” and “feature”
options, as per the following table:
Mode A: Standard Configuration
Start/Stop/High Level operation. When the Pump Start input is closed contact (triggered), the Duty Pump will be 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 func-
tions 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:

Function
Mode A:
Standard typical float switch configuration (Start, Stop and High Level). No Low Level
Mode B:
Standard configuration plus low level (Start, Stop, High Level and Low Level).
Mode C:
Standard configuration plus Prime Loss enabled, on Low Level (Input 1)
Mode D:
Pressure Pumping configuration (Lead, Lag and Low Pressure)
Operating Pump alternates each time a pump start is triggered, or after 30 minutes continuous
running.
Operating Pump alternates after 6 hours continuous running.
Anti-seize Timer disabled
Anti-seize Timer 6 seconds every 7 days enabled
When placed in Manual Mode, pump remains in Manual Mode
When placed in Manual Mode after 5 minutes the pump will revert to Auto
High Level Alarm automatically resets upon open circuit of high level input. High Level alarm
has 15 minute delay.
High Level Alarm can only be reset manually. High Level Alarm has 5 minute delay.
