TROUBLESHOOTING PROCEDURES
A list of symptoms directs attention to specific components and possible causes of the machine prob-
lems. The type of malfunction and identification of the component then permits a logical decision to
repair, replace or investigate further in order to correct the fault. A complete loss of control may be
caused by two malfunctioning components acting together, repair of one cause may restore operation,
but it may also permit a recurrence if the second malfunctioning component is not repaired. For refer-
ence the following is a complete listing of PLC input and output devices. Refer to electrical schematic
for additional details on machine wiring logic.
