ERROR: Trail switch not in right position (XXX)

The alarm occurs if the PLC controller does not detect the cylinder input in the expected time, after the activation of the output to move the switch to the right position.

• Check air pressure on the manometer. The set pressure must be 5 bar. In the pneumatic cabinet, check if the corresponding valve is activated. The valves have an LED activity indicator.

• Check pneumatic cylinder of the trail switch.

• Test the operation in manual mode, via the switch on the hanging control unit.

Check the operation of the magnetic position switches on the pneumatic cylinder. The LED indicator on the switch must be switched on at the limit positions. Adjust the switch position if necessary. The actual status of the switch inputs on the cylinder can be checked on the status screen; "OVER HEAD CONVEYOR".

If you need additional information, call the Gostol TST service department.
