Troubleshooting
1.
Capacity is inadequate:
Reason
Remedy
The inlet filter is dirty
Clean the inlet filter or change it
The pressure conduit is too long or too narrow
Provide a larger diameter conduit, clear the restriction sites.
Leaky compressor or within the system
The compressor and feed conduits should be checked for pressure
losses
The vanes are damaged
Replace the vanes
2.
The compressor shut down by the motor protection switch:
Reason
Remedy
The tension/frequency does not conform to the motor
data
Conform to the motor data
The motor protection switch is incorrectly set
Check the setting of the motor protection switch
The motor protection switch turns off too quickly
Use a motor protection switch with an overload hanging switch-off
component that takes account of the brief overload at the start (the
model has a short-circuit- and overload correction component
according to VDE 0660 Part 2 or IEC 947-4)
Connection at the motor circuit board or plug is
incorrect
Check the connections and/or plug
Counter-pressure in the pressure conduit is too high
The counter-pressure should conform to the technical instructions
3.
The end pressure (maximum pressure) is not reached:
Reason
Remedy
Leakage at the air exhaust side of the compressor or in
the system
Check the compressor and conduits for pressure loss
The vanes are worn or damaged
Replace the vanes
4.
The compressor over-heats:
Reason
Remedy
The ambient- or suction temperature is too high.
The suction temperature must be between 5 °C and 40 °C
The counter-pressure in the pressure conduit is too
high
The counter pressure should conform to the technical instructions
The cooling air flow is hindered
The cooling air inlet and cooling air outlet must be at least 10 cm
distant from the nearest wall (exhaust cooling air must not be re-
sucked in)
