Inflation Unit Support Library

Possible Cause: No power supply

Solution: Check and restore power supply

The inflation process does not commence. Even when the pressure is set and the hose is connected to the tyre.

Possible Cause: The tyre is deflated below 3psi / 20 kPa / 0.2 bar

Solution: Press [start] button

Possible Cause: The hose chuck is faulty

Solution: Replace the hose chuck

The display will not move / is stuck / is frozen on a particular value.

Possible Cause: The switch is damaged

Solution: Remove and clean the faceplate

Possible Cause: The deflate tubing is damaged

Solution: Remove and clean the silencer plug

Possible Cause: The beeper is damaged

Solution: Replace the beeper

Possible Cause: Low or nil supply pressure 

Solution: Check and restore the supply pressure

Possible Cause: unstable pressure due to faulty chuck

Solution: Replace the hose chuck

Possible Cause: unstable pressure due to faulty hose

Solution: Press the [flat tyre] button to ensure air is purging correctly. You should hear 5x bursts of air. Replace the hose if not.

Possible Cause: unstable pressure due to unit fault

Solution: If chuck and hose is in working order, remove the hose from the unit and test. If Er1 message continues, contact Airtec Corporation.

Possible Cause: Persistent unstable pressure, faulty hose chuck

Solution: Replace the hose chuck 

Possible Cause: Incorrect supply pressure

Solution: Check the air compressor supply pressure 

Possible Cause: Inflate & Deflate valve connections are reversed

Solution: Check the valve connections on the PCB

Possible Cause: Low or nil supply pressure

Solution: Check the air compressor supply pressure

Possible Cause: Initial or final pressure is too high, exceeding the maximum pressure by more than 20 psi / 140 kPa / 1.4 bar

Solution: Disconnect hose chuck, reset processor by switching off the power for a minimum of 5 seconds. If error message reappears contact an authorised technician to replace PCB

Possible Cause: Low supply voltage

Solution: Check power supply. The message will clear when the correct voltage is restored

Possible Cause: Programme or PCB Error

Solution: Reset machine by switching off the power for a minimum of 5 seconds. If error message reappears contact an authorised technician to replace PCB 

Possible Cause: Insufficient supply pressure

Solution: Check the air compressor supply pressure 

Possible Cause: Loose hose chuck

Solution: Check hose chuck

Possible Cause: Calibration error

Solution: Unit requires calibration, contact your local service agent to facilitate

Possible Cause: Automatic Calibration Check/Calibration Error

Solution: Reset machine by switching off the power for a minimum of 5 seconds. The ER9 message will clear automatically when the factory calibration is restored. If the ER9 message continues to appear, replace the PCB board

Possible Solution: Unstable supply pressure

Solution: Check the air compressor supply pressure

Possible Solution: Hose disconnection during inflate cycle

Solution: Check the hose chuck

Possible Cause: Short circuitry on valve connection 

Solution: Check and dry the valve connection

Possible Cause: Short circuitry on buzzer connection

Solution: Check and dry the buzzer connection

Possible Cause: Emergency stop button has been pressed

Solution: Disconnect hose from tyre, check and reset Emergency Stop button
