3 CCP800 series Trolley & Ancillaries Maintenance
3.1 Trolley Power
3.2 Bluetooth Oil Temp Probe
Always return the probe back to the holster
when not in use. Failure to follow this
process may lead to poor charge in the
batteries and not enough to complete a test.
3.3 Oil Temp Probe Length
Always adjust the probe to the correct length
prior to starting a test, it should be 10mm
shorter than the dipstick.
Failure to follow this process may cause not
only probe but engine damage.
3.4 RPM Device (Battery Tach)
To minimise the risk of unstable readings
load the battery by turning on headlights,
fog lights etc. Keep the cabin fan o as this
may introduce interference. Some modern
vehicles may not be detected due to “smart
charging systems” cutting the charge when
the battery does not require it. This is not a
fault with the equipment.
Daily
At the end of the day shut down the PC
and then turn the power o using the
switch on the side of the trolley leaving
the unit plugged in and switched on at the
mains. Failure to follow this process may
lead to poor charge in the batteries and
not enough to complete a test.
■ If the test still fails, ‘pinch o’ the pipe immediately after the gas lter bowl (see Fig 3.
overleaf) and retest.
■ If problem cured, check all joints on sample inlet and lter bowl assembly, particularly the
bowl to bowl adapter.
■ Unscrew lter bowls and ensure the 'O' rings are in good condition and have not been
'pinched' during assembly.
4 Vehicle Exhaust Gas Analyser (VEGA) Fault Finding
4.1 Leak Test Failure
The system is drawing in air, possible causes of a leak test failure are faulty joints, particularly in
sample probe/hose assembly and between the two lter bowls. Damaged 'O' ring seals of lter
bowls, particularly if lters have just been changed.
4.2 Checks
■ Pump operation - Is the pump running?
■ Disconnect sample hose from the gas analyser
■ Block the sample inlet and re-test
■ If problem cured, inspect joints for leaks/damage
■ Ensure exible probe is not damaged
■ In cases of extreme exhaust gas temperature the PTFE liner may melt and cause leak test
failure
Check exible P.T.F.E liner
inside braiding. Replace the
exible probe end if
necessary.
