Action: Check main supply. Check 2A fuse, which must be fitted to protect the installation. If the fuse has
blown there may a fault with the supply to the unit. Check the cable for damage/short circuits before fitting
another fuse. Check continuity of wiring to the unit.
4. Cause: The printed circuit board has failed.
Action: Check main power supply (see A3 above). Check power in at +ve and –ve on PCB. Check power
out on PCB at MM (to motor). NB Power out is AC. If no power out, replace PCB.
5. Cause: The motor/gearbox assembly has failed.
Action: Check for correct AC supply to motor (see A4 above). If power supply is correct but motor not
rotating replace motor/gearbox assembly.
B. One or more (but not all) lubricant points are dry.
1. Cause: Pipes supplying the dry lubrication points have worked loose from their connection.
Action: Check pipe connections and re-connect where necessary. Ensure sufficient tubing allowance,
particularly on King Pins and other moving lubrication points.
2. Cause: Pipes supplying the dry lubrication points are damaged or crushed.
Action: Install new pipes, re-routing if necessary to avoid repeat damage.
3. Cause: No output from pumping units due to blockage.
Action: Empty the reservoir and replenish with new, clean lubricant of a suitable grade. Fit new pumping units.
Do not attempt to clean and reuse blocked units as this could result in further problems resulting in damage to
bearings.
