The lifting elements are equipped with electro-mechanical drives. The controller converts AC
power to 28V DC to operate the motors with pulse width modulation (PWM 15 kHz 0 - 100%). The
controller is used to activate the raising and lowering of the lifting elements of the Height
Adjustment System.
As soon as the operator presses the arrow keys (Up or Down) of the connected manual switch, the
controller receives the signal to set the electro-mechanical drive of the lifting elements in motion.
Depending on the direction of the arrow the motor moves the lifting elements up or down.
