Operational Checks - EKOM DUO Benutzerhandbuch

19.2. Operational checks

 Check air pump condition – the air pump s should be operating normally without excessive
vibration or noise. Troubleshoot any problem or call in service personnel if trouble is detected
 Visually inspect fan operation – the fans must be operating when the air pumps are running.
Troubleshoot any problem or call in service personnel if trouble is detected
 Check to ensure the power cable and pneumatic hoses are undamaged. Replace damaged
components or call in service personnel.
 Check the ambient temperature – the ambient temperature must be below the temperature limit
(40 °C). Cool the space if the temperature is high.
 On the compressor with dryer – open the plug on the condensate collecting bottle to drain the
condensate.
19.3. Pneumatic connection leakage check and device inspection
Leakage check:
 Perform the leakage check of pneumatic connections when the compressor is operating –
pressurizing.
 Use a leakage analyser or soapy water to check all joints and connections for leaks. Tighten or
reseal the connection where leaks are found.
 Device inspection:
 Check the condition of the air pump for normal operation and noise levels.
 Fan operation check - the fans must be running during the defined compressor work cycles
 Check of temperature switch operation (B2) – heat the temperature switch to a temperature
above 40°C (e.g. using a heat gun, being careful not to warp any plastic pieces nearby). Fan
EV1 (and EV2 for a compressor with dryer) will start up once the temperature reaches 40°C so
long as power is connected to the compressor.
 Check filter condition – the filters must be undamaged and sufficiently clean.
 Check the condition of the air pump itself - ensure there is no contamination inside the
crankcase or play in the crankshaft
 Replace any defective parts as needed.
19.4. Inspection of electrical connections
Check all electrical connections on the device with the mains disconnected!
Inspection
 Check the mechanical function of the main switch.
 Check to ensure the power cable and connected wires are undamaged.
 Visually inspect the connection of individual cables to the terminal strip.
 Inspect all screw terminals for the protective green and yellow PE grounding conductor.
