How Does It Work?

The Mac3 Quadri is a direct on-line starter and pump controller for use with single and three-phase systems.

The Quadri can control up to two pumps depending on the model and is able to balance the workload by alternating the starts of each pump (unless demand requires both pumps be activated simultaneously). The Quadri uses float switches/level probes and/or pressure switches to determine if single or both pumps are required.

This controller functions in an automatic or manual configuration.

Automatic configuration allows the Quadri to test the connected hardware, determine the correct input/output levels, and then operates within them.

The configuration allows the user to pre-set the following operating parameters:

● Wait filling time

● Motor start delay duration

● Maximum motor current ( over-current protection)

● Minimum and maximum operating voltage

Operational parameters can be viewed on the LED’s and edited on the potentiometers on the circuit board. This allows the Quadri to display system information such as:

● The operational status of the motor

● Error messages

● Defined parameters of operation

The Quadri can run in three modes:

● Boosting

● Storage

● Sewage

Boosting allows the Quadri to function with a pressure boosting system, using both probes and pressure switches to monitor and run pumps when a pressure or level drop is detected.

Storage allows the Quadri to monitor the levels in two tanks, and function as a level controller.

Sewage allows the Quadri to use float switches to determine levels inside a tank and pump according to the parameters set by the installer.
