3 Pump overload
alarm light
When the pump current is too high, the
light will be on, and the buzzer will give
the alarm.
The system will stop working.
Check whether the motor is
stuck or the bearing is damaged.
If the motor is OK, check whether
the setting current of the thermal
overload relay in the electric
control box is too small. After the
above faults are eliminated, wait
for about 1 minute and reset the
thermal overload relay by
pressing the blue reset "reset"
button of the thermal overload
relay to reset the alarm.

Compressor
overload
alarm light
When the working current of the
compressor is greater than the set value
of overheat switch, the light will be on,
and the buzzer will give the alarm.
The system stops working.
Check whether the setting
current of overheat relay is
correct.
The current setting value of the
overheat switch must be greater
than the compressor’s rated
current.
5
Over-pressure
alarm light
When the compressor’s outlet pressure
is higher than the setting value of the
high-pressure switch, the light will be
on, and the buzzer will give the alarm.
The system stops working.
Check whether the setting value
of the high-pressure switch is
rational. The setting value of the
high pressure switch is 25bar.
6
Low-pressure
alarm light
When the compressor’s air inlet
pressure is less than the set value of the
low pressure switch, the light will be on,
and the buzzer will give the alarm.
The system stops working.
Check whether the setting value
of the low-pressure switch is
rational. The setting value of the
low- pressure switch is 2 bar.
7 Buzzer
The buzzer gives audible alarm when it
detects the problems.
8
Compressor
switch
The start & stop of the compressor.
Note: The pump must be turned
on before compressor startup.
9 Pump switch The start & stop of the pump.
Note: Pump rotating direction
must be correct.
10 Main power switch
Main power supply of the control
system.
11
Temperature
controller
Temperature setting and controlling.
See Chapter 4.4 for detailed
settings.
