Table 5-2: Double Compressor
Fault
Test Conditions
Troubleshooting
Solution
Compressor 1
pressure high
Test when the compressor
button has pressed
Stop compressor 1
only without affect
other equipments to
work.
Check if the input is consistent
with the switch setting.
Compressor 1
pressure low
If the [LP Check Delay] is 0, test
when the compressor button has
pressed;If the
[LP Check Delay] is not 0, then
compressor 1 runs the test.
Compressor 1
overload
Compressor 1 runs the test
Compressor 2
pressure high
Test when the compressor
button has pressed
Stop compressor 2
only without affect
other equipments to
work.
Check if the input is consistent
with the switch setting.
Compressor 2
pressure low
If the [LP Check Delay] is 0, test
when the compressor button has
pressed;If the
[LP Check Delay] is not 0, then
compressor 2 runs the test.
Compressor 2
overload
Compressor 2 runs the test
Water Temp. Low
Runs test
Stop the compressor,
and do not stop the
pump.
Check if the water temperature is
lower than the set temperature of
Liquid protection.
Water Temp. High
Stop the compressor,
and do not stop the
pump.
Check if the water temperature is
higher than the set temperature of
Liquid protection.
Anti-freeze Err
Power on to test
Stop the compressor,
and do not stop the
pump.
Check if the antifreeze input is
consistent with the switch setting.
Water-temp.
Sensor breaks
Check if the temperature probe is
in proper contact.
Water-temp.
Sensor short circuit
Anti-freeze
Sensor breaks
Anti-freeze
Sensor short circuit
Anti-freeze
temperature is too low
Stop the compressor,
and do not stop the
pump.
Check
if
the
antifreeze
temperature is lower than the set
temperature
of
antifreeze
protection
Blower 1 fault (Only
applicable for
air-cooled series)
Compressor 1 runs the test
Stop the compressor,
and do not stop the
pump.
Check if the blower 1 fault input
input is consistent with the switch
setting.
Blower 2 fault (Only
applicable for
air-cooled series)
Compressor 2 runs the test
Check if the blower 2 fault input
input is consistent with the switch
setting.
Water flow short
Test after the pump starts for
(Pump on delay)time
Stop the unit
Check if the water flow input is
consistent with the switch setting
Pump Overload
Test after pump starts
Stop the unit
Check if the pump overload input
is consistent with the switch
setting.
Phase Err
Power on to test
Stop the unit
Check if there is default phase or
anti-phase in the three-phase
power input and if the switch is
correct.
Water Level Low
Power on to test
Stop the unit
Check if the water level input is
consistent with the switch setting.
Need Maintenance
Test after pump starts
The unit connot start once stops(the accumulative operation
time of compressor exceeds the set value)
