COSMEFROIARLT COMNTMRUONLI2CSAYTSIOTNESM™COCNOTNRTORLOWLIWRIINRGING Active Protection - Code L29 - Open high pressure control IMPORTANT: This mode of active protection must be manually reset. 3) Locked Rotor • The ICC will display a flashing "L" followed by a flashing "04" when a locked rotor condition occurs. Active Protection - Code L4 - Locked rotor If the ICC detects the compressor has run less than 15 seconds for four (4) consecutive starts during the same command for unit operation, the ICC will lockout the compressor to keep it from continuing to operate and flash a "L" on the dual 7segment LEDs followed by a "04". IMPORTANT: This mode of active protection must be manually reset. 4) Compressor Protector Trip • If ICC detects a protector trip it will display a "P". If protector doesn't reset within 4 hours, the ICC display will change to "5". Compressor Protector - Code P - Protector Trip 5) Open Start Circuit Lockout • The ICC will display a flashing "L" followed by a flashing "06" when an open start circuit condition occurs. Active Protection - Code L6 - Compressor open start circuit If the ICC detects current in the run circuit without current present in the start circuit, , the ICC will lockout the compressor to keep it from continuing to operate and flash a "L" on the dual 7-segment LEDs followed by a "06". IMPORTANT: This mode of active protection must be manually reset. 6) Open Run Circuit Lockout • The ICC will display a flashing "L" followed by a flashing "07" when an open start circuit condition occurs.

condition occurs.
Active Protection – Code L4 – Locked rotor
If the ICC detects the compressor has run less than 15 seconds for four (4) con-
secutive starts during the same command for unit operation, the ICC will lockout
the compressor to keep it from continuing to operate and flash a “L” on the dual 7-
segment LEDs followed by a “04”.

5) Open Start Circuit Lockout
• The ICC will display a flashing “L” followed by a flashing “06” when an open start
circuit condition occurs.
Active Protection – Code L6 – Compressor open start circuit
If the ICC detects current in the run circuit without current present in the start cir-
cuit, , the ICC will lockout the compressor to keep it from continuing to operate
and flash a “L” on the dual 7-segment LEDs followed by a “06”.
IMPORTANT:
This mode of active protection must be manually reset.
6) Open Run Circuit Lockout
• The ICC will display a flashing “L” followed by a flashing “07” when an open start
circuit condition occurs.
