Electrical Connection Options and Electronic Accessories
Light barriers or light scanners
For starting the conveyor at the beginning of the belt: When a part is detected by a light barrier, the conveyor belt starts. For stopping the conveyor at the end of the belt: When a part is detected by a light barrier, the conveyor belt stops.
Foot switch or hand switch
After pressing the switch, the belt runs for a predefined period of time or distance.
After pressing the switch, the belt continues running until the switch is pressed once again.
Automatic timers
The belt starts after a predefined waiting period and runs for a predefined period of time. Afterwards, it stops automatically again.
Counters
In combination with a light barrier or mechanical sensor the counter counts a defined number of impulses and then stops the belt.
- Motor Protection Switch
At a constant belt speed the three-phase motor of the conveyor is connected to a 380-415V 50 Hz three-phase current and protected against overcurrent by means of a motor protection switch.
If the conveyor is blocked due to a mechanical problem or is loaded by too much weight, the motor protection switch prevents the motor from receiving too much electrical current so it does not heat up or get damaged.
The motor protection switch is also equipped with an emergency off in the form of a rotary switch.
- Belt Running Empty
In case of an adjustable belt speed the three-phase motor is connected to a frequency converter. This is connected to a standard plug for a 230V 50 Hz alternating current. The frequency converter has the following advantages:
- digital device
- freely programmable
- smooth start and stop possible
- adjustable min and max speed
- start- stop- sequences programmable
- clocking by external signal possible
- integrated motor protection against overcurrent
- Emergency Stop Switch
The emergency stop switch is compatible with all types of conveyors. Several interconnected switches can be mounted at the same time, allowing the operator to stop the conveyor instantly from any switch and any position.
Electronic Control
Many other electronic control options are also available in combination with the digital frequency converter.
