DESCRIBE the PROBLEM
Most problems are apparent and easy to fix. However, the more information we have about what
caused the problem, the more we can do to improve our product so that these problems do not
occur in the future.
In some cases we may NOT be able to duplicate YOUR particular problem in OUR testing facility.
Describing the problem as CAREFULLY and as completely as possible will help us locate and
correct any design weakness that might be responsible for the problems you are having.
IN HOUSE REPAIRS
1. If a controller fails to respond properly to counter settings, cycle input signal, or on/off
signals properly, you may make an inspection of the internal electronics.
Work only in a relatively clean environment. Inspect all cable connections to be sure each is
tight and that proper connection is being made by each individual wire and clip within each
connector; individual wire clips can sometimes pull loose from the connector. Inspect all
solder connections for broken wires or improper solder connections.
Inspect the magnet holding cup on the rear of the motor. If this assembly should loosen,
this will adversely affect motor control. Take care not to disturb or damage the electronic
hall effect device that is attached to the rear of the motor. Repairs to printed circuit boards
should not be attempted. Generally, if a component fails it indicates a condition that may
have caused other components to fail as well. Boards should be returned to the factory for
repair. A blown fuse on a circuit board usually indicates that other problems are present. A
new fuse of similar size and rating may be substituted but if it blows again, the board should
be returned to our factory for service. DO NOT EXCEED 5 AMPS on the board.
