ACTIVE DRIVER T/T 3.0

Suits three phase power supply, and will couple to three phase pump units up to 3.0kW,

and is programmable to a maximum pressure of 9 Bar (900kPa), not exceed a flow of

300lpm.

ACTIVE DRIVER T/T 5.5

Suits three phase power supply, and will couple to three phase pump units up to 5.5kW,

and is programmable to a maximum pressure of 9 Bar (900kPa), not exceed a flow of

300lpm.

>Selecting the Correct Pump.

It is import ant to choose the correct pump when utilizing the ACTVE DRIVER as a constant

pressure control device. It is important that the pump is selected to provide the maximum

potential flow at the desired demand pressure.

>>For Example,

If a duty point of 100lpm at 350kPa is required,

then this should be assumed as the maximum

required duty of the pump.

An ideal selection for this would be the DAB

KVCX35/120, as it will provide the flow

required at around 380kPa and the required

pressure at a maximum flow of 115lpm.

As the ACTIVE DRIVER is controlled by required

pressure, inputting a set point of 350kPa will

mean that the pump will normally run at lower

frequency (speed), and less likely to cavitate.

>Installing the ACTIVE

DRIVER

The ACTIVE DRIVER would normally be

installed in an upright position, on the

discharge side, above the main body of water

in the pump.

A check valve should be installed inlet to the controller or in the suction port of the pump.

Failure to install a check valve will result in the unit cycling.

The ACTIVE DRIVER is pressure sensitive and a suitable sized ENERGY SAVER should be

installed on the discharge side of the controller. The pre-charge should be set to be slightly

lower (15kPa min) that the restart point set in the controller, which is factory set at 0.5 Bar

(50kPa) below the set point.

The AD M/T 1.0, AD M/T 2.2, AD T/T3.0 and AD T/T 5.5 can be interconnected with up to three

units (total) operating as one system, allowing for alternating starts and various inputs and

outputs for integrated operation.

If using the AD M/M 1.1, retain the PLUG and PLAY fly lead supplied with the pump as it will be

helpful in priming the pump before attempting to set the ACTIVE DRIVER.

This allows you to use the pump in a manual mode while priming is completed.
