The electronic speed controller of these series control the speed of single phase (230 VAC – 50
HZ) voltage controllable motors by varying the supplied voltage through phase angle control.
There is a potentiometer and a separate ON/OFF switch with built in tell tale, The minimum
speed allowed can be adjusted internally with a little trimmer (Factory pre-set = 100V). The
terminal board has a supplementary connection to bypass the ON/OFF switch (automatic start)
or to branch off230V not controlled (three wire motor connection, valve, lamp, damper, etc...)
There are two working modes internally selectable by placing or removing the red jumper on
the PCB (See illustration)
Kickstart : the motor will always start (or reset ) at max speed for 8 seconds, after that the
motor speed automatically follows the position of the potentiometer.
Normal start : the motor starts according to the position of the potentiometer.
1.
Be sure that the controller is in the OFF position.
2.
Take off the box cover by loosening the 4 screws. Note that the potentiometer is
connected to the PCB with 2 wires.
3.
Connect mains, motor(s) and earth cables of the proper diameter to the terminals
according to the scheme below.
4.
Start the controller and adjust the little trimmer so that the motor continues turning or
restarts smoothly in case of power faults. The minimum speed is factory preset at 100V
5.
Close the box and verify that the installation works fine.
6.
The operating position must be shown below.
