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 setup and configuration options.
OPERATION
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 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:
