TROUBLESHOOTING

Protection Circuit Fault Isolation

Protection diagnosis of the complete machine (all types of protection during operation, i.e. under-voltage, over-voltage and

overcurrent protection)

Note:List all types of protection that may occur to the complete machine and describe the conditions and signs of the start, course

and end of such protection.

Voltage protection
Protection against AC input over-voltage/under-voltage

1.Conditions for protection against AC input over‑voltage/under‑voltage:

If the input AC voltage is greater than “protective over‑voltage value” or less than “protective under‑voltage value” for five seconds,

over‑voltage/under‑voltage protection starts. (E6)

2.Protection actions against AC input over‑voltage/under‑voltage

The system stops operation.

3. Conditions for ending AC input over‑voltage/under‑voltage:

If the input AC voltage is lower than “the protective over‑voltage value” ‑10V, or higher than “the protective under‑voltage value”

+10V, the over‑voltage/under‑voltage protection will be released.

Current protection:

1.Protection against over‑current

Conditions for over‑current protection: if the current is equal to or greater than “current value for starting the refrigeration current

protection (E2 value)” for six seconds, over‑current protection starts.

Protection actions against over‑current: indoor display screen and outdoor indicator give indications, the compressor and outdoor

fan stop, but indoor fan runs normally.

Condition for ending over‑current protection: when the current drops below “current value for releasing the refrigeration current

protection (E2 value)”, over‑current protection will be released.

2.Frequency decreasing for over‑current

Conditions for over‑current frequency decreasing: if the current is equal to or greater than “current value for starting the

refrigeration current protective frequency decreasing (E2 value)”, over‑current frequency decreasing starts.

Over‑current frequency decreasing actions: the compressor will decrease frequency at rate of (E2 value)Hz/S. The indoor and

outdoor fans run.

Conditions for ending over‑current frequency decreasing: when the current drops below “current value for starting the refrigeration

current protective prohibition of frequency rising (E2 value)”, over‑current under‑clocking will be released.

*Is the limit auto‑reset*

3.Prohibition of frequency increasing of compressor exhausting

Conditions for prohibition of frequency rising of compressor discharge

Condition 1: in the case of frequency decreasing of compressor discharge, the discharge temperature of the compressor drops below

39.2F

Condition 2: in normal operation, the discharge temperature of compressor reaches 41F.

Either of the above two conditions is met, prohibition of frequency rising of compressor discharge begins.

Actions relates to prohibition of frequency rising of compressor discharge: the frequency of compressor maintains at the current

level, which may decrease as the case requires while cannot rise. The indoor and outdoor fans run.

Condition for ending prohibition of frequency rising of compressor discharge: if the temperature of compressor discharge rises

above 42.8F, prohibition of frequency rising of compressor discharge will be released.

4. Prohibition of frequency for anti-overload of outdoor coiled pipe (cooling condenser temperature high) – To prevent compressor

overload from tripping.

Condition for anti‑overload prohibition of frequency of outdoor coil pipe: in the case of anti‑overload frequency decreasing of outdoor

coiled pipe, anti‑overload prohibition of frequency of the unit begins when the temperature of outdoor coiled pipe drops below “the

anti‑overload frequency decreasing temperature of outdoor coiled pipe”.

Actions relates to anti‑overload prohibition of frequency of outdoor coiled pipe: the frequency of compressor maintains at the current

level, which may decrease as the case requires while cannot rise. The indoor and outdoor fans run.

Condition for ending anti‑overload prohibition of frequency of outdoor coiled pipe: if the temperature of outdoor coiled pipe drops

below “temperature to release the anti‑overload state of outdoor coiled pipe”, anti‑overload prohibition of frequency of outdoor

coiled pipe will be released.
