Corrective actions:
1. if you spot an incorrect resistance, a short-circuit or open electromagnet, replace it.
2. if the electromagnet is not working, check the board or the voltage
3. if the electromagnet is moving, fasten the base screws.
Electromagnets adjustments (if necessary)
1. Force the lock against the sprocket and the equipment's arm until the lock is
completely inside the first teeth (until the arm is locked)
2. then, release the fixing screws and press the electromagnet against the lock's frame,
so that its area is completely against the electromagnet
3. refasten the screws
Set of locks – Periodicity: every 700,000 cycles
To check for the need of corrective actions, you must:
-check the lock's correct position
-check the wear of the lock's fitting in the sprocket
Corrective actions
1. if the lock's position is incorrect, check the retaining ring and the spring that tightens
the set
2. if the lock's fitting to the sprocket is incorrect, replace the lock or the sprocket
3. if lock's end is worn, replace the lock
Sprocket set – Periodicity: every 700,000 cycles
To check for the need of corrective actions, you must:
-check the wear of the sprocket's teeth
-check the gap between the central axis, the sprocket, and the keyway
Corrective actions
1. if you observe wear on the parts' teeth, replace the parts
2. if you see a gap between the sprocket and the axis/keyway set, replace the sprocket
or the keyway (to replace the sprocket, use a pulley puller)
