Chapter 7
Periodic Maintenance
7-2
ATTENTION: Use of other than factory recommended test
equipment for solid state controls may result in damage to the
control or test equipment or unintended actuation of the controlled
equipment.
Static Sensitive Items – While performing maintenance on the 1395 Drive
and the Discrete Adapter, special precautions must be observed in handling
or touching certain static sensitive components in the cabinet. All circuit
cards and SCR’s in the drive can be damaged by Electro-Static Discharge.
If personnel will make contact with an ESD sensitive component during
maintenance, they must be grounded. Grounding should be accomplished
with a wrist strap which is connected to an approved ground.
Tests and Records
Final Check Out – After maintenance or repair of industrial controls,
always test the control system for proper functioning under controlled
conditions that avoid hazards in the event of a control malfunction.
“Keep Good Maintenance Records” – This rule will be most helpful in
locating possible intermittent problems by pointing to a particular area of
recurring trouble within the overall system. Further, good maintenance
records will help reduce major costly shutdowns by demanding the use of
proper test equipment and an appropriate inventory of spare parts. For
additional information see NFPA 70B, “Recommended Practice for
Electrical Equipment Maintenance,” published by the National Fire
Protection Association.
