8 MAINTENANCE/TROUBLESHOOTING
e 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 every 6 months.
• Check the air intake screens and louvers, fan and cooling
chamber, and exhaust openings for any obstructions or
foreign objects.
• Check fan blades for stress fractures.
• Check the exhaust vent for obstructions
• Check the load branches 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. e three current readings should be essentially the
same. If a sizable dierence is noted, one or more load fuses or
load resistors may have malfunctioned.
Check the tightness of the electrical connections. e
expansion and contraction caused by load bank operation may
cause loose connections. For a detailed inspection guide, see
“Primary Inspection” on page 6.
