Excess grease Remove grease fitting, and direct jet of filtered
compressed air into opening to remove grease.
Incorrect grease Lubricate with recommended grease (refer to
Preventive Maintenance).
Defective bearing Contact Derrick Service department for assistance.
F7011 - Air Conditioner Compressor Motor Overload Fault
Motor drawing excessive current
Confirm proper operation of relays K20 and K30 and
adequacy of three-phase power supply. Check all
electrical connections. Correct any defects.
F7012 - Air Conditioner Internal Fan Motor Overload Fault
Motor drawing excessive current
Confirm proper operation of relays K20 and K30 and
adequacy of three-phase power supply. Check all
electrical connections. Correct any defects.
F7013 - Air Conditioner Refrigerant Pressure High or Low Fault
Refrigerant pressure high or low
Attempt to re-start centrifuge. Low pressure will
cause immediate shutdown or failure to start; high
pressure will permit brief operation and then
automatic shutdown. If low pressure indicated,
contact Derrick Service for assistance. If high
pressure indicated, continue troubleshooting.
Condenser motor rotation incorrect or
motor defective
Check rotation direction, and reverse, if necessary,
by switching two leads.
Condenser cooling fins clogged Use vacuum cleaner to remove all debris from fins.
Condenser motor defective
Check motor, and replace if defective. If problem
persists, contact Derrick Service for assistance.
