PL10-2D
Run Off Switches
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. |
