Solid-State Devices
A T T E N T I O N A T T E N T I O N 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. Refer to paragraph titled HIGH
VOLTAGE TESTING.
Solid-state devices require little more than a periodic visual inspection.
Discolored, charred or burned components may indicate the need to replace
the component or circuit board. Necessary replacements should be made
only at the PC board or plug-in component level. Printed circuit boards
should be inspected to determine whether they are properly seated in the
edge board connectors. Board locking tabs should also be in place. Solid-state
devices must also be protected from contamination, and cooling provisions
must be maintained – refer to paragraphs titled CONTAMINATION and
COOLING DEVICES. Solvents should not be used on printed circuit boards.
Locking and Interlocking Devices
Check these devices for proper working condition and capability of
performing their intended functions. Make any necessary replacements only
with Allen-Bradley renewal parts or kits. Adjust or repair only in
accordance with Allen-Bradley instructions found in the product User
Manuals.
