Operate the controller via the external device output voltages.
Optional settings
The standard configuration of the output voltages is as indicated in
Table 1
below.
However, because more than 5 output voltages are available, it is possible to adjust
the 5 steps by changing the internal wiring.

VERIFICATION OF INSTALLATION
ATTENTION
Use only tools and equipment with non-conducting handles when working on
electrical devices.
After connecting the unit to the mains supply, the green LED on its cover should light
up to indicate that the controller is supplied.
Safe operation depends on proper installation. Before start up, ensure the following:
■
The mains supply is connected correctly.
■
Protection is provided against electrical shock.
■
The cables are the appropriate size and fuse-protected.
■
There is sufficient air flow around the unit.
The controller is equipped with TK terminals to connect to the thermal contact
integrated in the motor. When actuated (in case of an overheated motor), the
thermal contact cuts the voltage supply to the motor and switches on the red LED
to indicate that it does not work.
ATTENTION
The unit is supplied with electrical energy at voltages high enough to inflict personal
injury or threat to health. Take the relevant safety measures.
ATTENTION
Disconnect and confirm that there is no live current flowing to the unit before servicing.
ATTENTION
Avoid exposing the controller to direct sunlight!
