Preventive Maintenance Checklist
It is the list in which the items of a radio remote control set to be checked at set intervals are written down in a fixed order. Its scope is gaskets, cable entries, terminal torque, the antenna, battery condition and contact wear. Sticking to the list catches faults before they turn into downtime.
The recommended order of checks is as follows:
- Housing: cracks and impact marks on the remote control and receiver, and whether the cover screws are complete and evenly tightened.
- Sealing: the elasticity of the cover gasket, the tightness of the cable entries, and any trace of moisture or condensation inside the housing.
- Connections: retightening of the terminal screws, checking for oxide and corrosion on connector pins.
- Antenna: physical damage, fixing, and that it has remained outside the panel and in a vertical position.
- Power: whether the shift duration has shortened on a rechargeable unit, and any trace of leakage in the battery compartment on a battery-powered unit.
- Contacts: signs of welding, overheating or burn marks on relay and contactor contacts.
- Function: no-load channel test, limit switches, direction interlocks and stopping behaviour.
The interval is set according to how intensively the equipment is used and the environment; it is shortened on dusty, salty and outdoor sites.
