activation of motor
protection
check the protection, replace or switch on
temperature indicator or
temperature transducerfault
check, replace if damaged
temperature indicator
(microprocessor controller)
activated because the
temperature was too high
check:
-
oil level and top it up if necessary,
-
cooling: remove causes of insufficient
cooling,
-
thermostat: if faulty, replace the entire
thermostat or its cartridge.
ambient temperature too
low
heat the room up to reach at least +5°C
difficult
compressor start
supply voltage too low
check supply voltage, bring it to correct value
ambient temperature too
low
heat the room up to reach at least +5°C
non return valve fault
call the service
wrong rotation
direction
wrong phase sequence
swap two phase leads in the compressor
terminal block or in the electric cabinet
oil temperature
too high, the
compressor does
not start
ambient temperature
> 40°C
ensure adequate ventilation in the room.
contaminated cooler
clean the cooler (exchanger)
operating pressure above
the set value
adjust the pressure switch or enter correct
settings in the controller
oil level too low
top oil up as required
oil thermostat malfunction
replace the entire thermostat or its cartridge

provide water to compressor
damaged temperature
transducer
replace with a new one
other causes
call service
forcing pressure
too low
wrong pressure switch or
microprocessor controller
setting
adjust the pressure switch or enter correct
settings in the controller
insufficient compressor
capacity in relation to air
requirement
install additional source of compressed air
leak in the system
check the tubing for leaks, remove leaks if any
air filter contaminated
change air filter cartridge (during the warranty
period to be replaced obligatorily by the
service staff only)
damaged pressure
transducer
replace with a new one
damaged suction regulator
call the service staff
activation of
motor protection
ambient temperature too
high
improve room ventilation
failure of one phase in motor
power supply
check motor leads, contactor and protection
supply voltage too low
ensure correct supply voltage
discharge pressure higher
than specified on the
nameplate
adjust the correct settings in the controller
