Adjustment of the belt speed
The speed of the conveyor belt can be adjusted by:
programming
the
BS
parameter on the Metal Detector
simply pushing the keys located on the Conveyor Control System.
For systems which allow inversion of the direction of travel, the
and
buttons can be
programmed for the forward and reverse movement of the belt, respectively. In this case, the speed
can be set only by going in to programming.
The manual forward/reverse movement of the belt is performed by holding pressed the corresponding button.
The increase/decrease speed controls are enabled both when the belt is stopped and the belt is running.
During programming of the Metal Detector, speed adjustment using the
and
keys is disabled.
When the Conveyor Control System keys are being used, the Metal Detector programming is disabled.
