Diagnostics is limited to simple check of contacts of conducting and drives on existence of insignificant damages which can be easily eliminated. Treat such checks:
- Check of safety locks of system and/or the breaker of a chain (where it is available).
- Check of wires of switches regarding damage of wires and weakening of contacts. Check of switches on conductivity.
- Remove the panel (panels) of a covering of a door and check contacts of conducting of the drive for easing or existence of damages. Examine drive rods to make sure that they are not bent and are not damaged. The drive can be checked, having quickly connected a power supply from the battery. The strong click will indicate that the electromagnetic valve works normally.
