5. Maintenance
5.1 Regular Maintenance
The All Makes Injector Test Unit AE32 does not require any regular maintenance procedures.
5.2 Troubleshooting
5.2.1 Status Indicator Light
The AE32 power status light gives the following indications:
Condition
Off
Mainly on, but flashing off every 5 seconds
Flashing on/off every second
Fully on.
The Trip Condition
Two conditions could cause the unit to trip: high current (meaning that the current delivered is not
controlled at the demand value), or extended pulse (meaning that the pulse has not turned off at the
required width).
To reset the unit switch off, wait a few seconds, and then switch back on. If the unit is still tripped,
switch off and disconnect the injector cable, then switch back on. The trip could be caused by a faulty
injector coil or piezo, or by a fault within the AE32. Try the injectors one at a time to establish if one is
faulty.
If you suspect a problem with the AE32 unit, contact your local Hartridge distributor (see below).
5.2.2 Other Faults
The only other intervention that we advise is to check the 5A fuse in the single phase power
connection unit.
For any more complex problems contact your national Hartridge distributor; we would recommend
that the unit is returned to Hartridge for investigation and repair. Please give as much information as
possible on the conditions when the fault occurred, e.g.
the injector type under test
the test speed
the solenoid current(s) applied
the pulse width applied
