VII. MAINTENANCE/TROUBLESHOOTING

VII-A. General Maintenance

The load bank has been designed to require minimum maintenance. All components
have been chosen for a long, reliable life. Two basic intervals of maintenance are
required: each operation and either every 50 hours or 6 months (whichever comes
first).

VII-B. Each Operation

The air intake screens and louvers, fan and cooling chamber, and exhaust openings
must be checked for any obstructions or foreign objects.
Due to the high volume of air circulated, paper and other items can be drawn into the
air intake. Clear the area around the load bank of any debris that may be sucked into
the intake area.
During load bank operation, ensure that air is exiting from the exhaust vent.
The load branches should be checked for blown fuses or opened load resistors. To
check the fuses or load resistors, operate the load bank from a balanced 3-phase
source and check the three-line currents. The three current readings should be
essentially the same. If a sizable difference is indicated, one or more load fuses or
load resistors may have malfunctioned.

VII-C. Troubleshooting

Any of the alarms detailed on
and dumping the load. All load steps are locked out until the problem is corrected. Until
the failure is investigated and corrected, the load cannot be reapplied. For possible
solutions to the problems causing the alarms, please consult
load bank still won't operate, please call the Simplex service department at
800-637-8603 ext. 4.

VII-D. Intake Temp. Failure

•
Clear intake screen located on bottom of unit.
•
Move load bank to cooler location or wait to conduct test on cooler day, if possible.
Remove all power before servicing the load bank.
Never operate or service a load bank that is not grounded.
