The PL10-2D Run Off Switch detects conveyor belt misalignment; two microswitches can trigger an alarm or conveyor shutdown to protect the conveyor belt from damage when belt drift occurs.
When the belt runs off center, the roller arm will be deflected from its normal vertical position and at a preset angle activates the first microswitch which can output to an alarm.
When the belt further displaces the roller arm by a preset angle, the second microswitch will be trigged to shut down the conveyor before damage can occur to the belt or plant.
The PL10-2D run off switch is usually installed in pairs at both sides of the belt and positioned at a distance between 0.3m and 2m from the head pulley or tail pulley.
Typically, it can be fastened at the top or bottom of the conveyor stringers with the actuating arm located 25mm to 75mm away from the outside edge of the belt.
