OPERATING INSTRUCTIONS
The controller is to be used only with voltage controllable fans / motors. You can
connect several motors to the controller as long as the current limit is not exceeded.
The motor used should be protected internally against overheating.
The trimmer is adjusted so that the motor does not stop due to mains voltage
variations. The controller restarts after power failure.
In case of faulty operation
Please check if:
■
the right voltage is applied;
■
all connections are correct;
■
the machine to be regulated is functioning;
■
the fuse of the controller is OK.
In case that the fuse has blown up, remove the knob by turning it to the right, beyond
the end stop and then pull. Open the cover and unscrew the nut. Remove the fuse
holder with the help of a screwdriver. Replace the fuse. Mount all the parts back in
place.
ATTENTION
Use only fuses with type and rating specified above.
