• Check door hinges, latches, and other moving parts for proper operation.
Use machine oil to lubricate the moving parts and restore proper operation
where necessary.
• Check for mechanical damage to any windows as well as check the window
seals. Repair or replace damaged materials.
In all cases where equipment damage is observed, a root cause analysis should be
initiated to determine any future corrective action needed to prevent a recurrence.
Wiring and Connections Survey
The wiring and connections survey recommended is as follows:
• If the servicing of removable electrical connectors is to be conducted, then
make certain the area is free of explosive atmospheres.
• If equipment is available, an infrared scan of the interior of the panel cabinet
and associated wiring (while in operation) is recommended. Any unusually
high temperatures at connections are usually evidence of poor connections.
Tighten connections, repair with new terminations, and/or replace any com-
ponents which have been exposed to long term overheating. All terminal
block connections should be tightened using a torque indicating screw driver
to the levels indicated in Table 1 and project installation drawings.
• Check for corrosion at electrical connections and terminations. Where cor-
rosion of electrical terminals is observed, this may be additional evidence of
loose connections and excessive heat. A part replacement may be neces-
sary.
• Inspect wiring for abrasion wear, mechanical damage, and thermal overex-
posure. Repair or replace any damaged or defective wiring.
In all cases where equipment damage is observed, a root cause analysis should be
initiated to determine any future corrective action needed to prevent a recurrence.
Control System Operation Check
The TCM18 controller screen is an ideal resource in facilitating operation checks of
the control system. To begin this program, energize the panel and the appropriate
heat trace circuits for a minimum of 24 hours or until all circuits are cycling within
their appropriate control band. A typical list of operational maintenance checks are
