4.4 Gas Analyser not
communicating
■ Check mains supply OK and the analyser
module is switched on
■ Check communication cable
■ Check platform Cong for conicts
4.5 LHC Residue Test Failure
■ Check sample probe in free air, blow out
sample probe & pipe assembly if required
■ Change gas lters if heavily contaminated
and wash lter bowls with warm soapy
water
4.6 Low Gas Flow
Ensure that the lters have been removed and
cleaned or replaced, sample probe has been
checked for damage and blockages.
4.7 High Lambda Readings
The system is drawing in air, please ensure the
following – All lter bowls are undamaged and
sealed (hand tight and a little bit, do not over
tighten or you will damage the o ring). Sample
probe and pipe are undamaged and
connections are tight.
4.8 Remove Probe from Exhaust
message (at beginning of an MOT
test)
Check the O2 sensor two pin connector is still
connected and the millivolt reading is no less
than 7 millivolts.
5.1 Battery Charging
The DX260-1BT wireless Smoke head contains
a Multi-Cell Rechargeable Battery designed to
give a maximum of 1.5 hours endurance from
a full charge.
The smoke head must always be replaced
on the charging cradle in between tests.
It is also strongly recommended that the
batteries be completely discharged on a
monthly basis by setting the program to
Live Readings with the smoke head off the
charger.
Please note that rechargeable batteries have a
nite lifespan, therefore the battery pack will
need to be replaced periodically if the smoke
head is no longer sustaining sucient charge
for correct operation.
5.2 LED Indication
Smoke head removed from charging
cradle:
■ LED ‘On’ continuously: Smoke head is
running on internal battery
■ LED pulsing ‘ON’ for 2 seconds, ‘OFF’
for 0.5 seconds: Smoke head battery
has reached a Low Voltage condition, and
has less than 10 minutes life left before
auto-shutdown.
■ LED ‘OFF’: Low Voltage condition.
Smoke head will auto shut down. No more
testing possible until smoke head battery
has been recharged.
If the smoke head has received no
communication from host computer for over
6 minutes it will go into ‘Sleep’ mode. Return
the smoke head to the charging unit to invoke
a response.
If the smoke head is taken outside its
maximum operating range of about 100
metres, and wireless communication is no
longer possible, after 6 minutes the smoke
head will go into ‘Sleep’ mode.
To recover from ‘Sleep’ mode, the smoke head
should be put back in its charging cradle, and
the LED function observed.
5 Battery Smoke Meter
(DSM) Fault Finding
Smoke head returned to Charging Cradle:
■ FAST CHARGE (2.5 flashes per
second): The Smoke head is in ‘Fast
Charge’ Mode. The battery should fully
charge within 1.5 hours
■ TOP-UP CHARGE (1 flash per second):
The Fast Charge cycle has completed and
the battery is being brought to full charge
■ SLOW CHARGE (1 flash every 2
seconds): The Smoke head battery is in
‘Slow Charge’ mode, the charging rate
determined by either terminal voltage or,
battery cell temperature
5.3 Battery Charging cont.
■ TRICKLE CHARGE (1 flash every 3
seconds): LED Flashing ON/OFF shows
the smoke head battery is in ‘Trickle-
Charge’ mode indicating that the batteries
are fully charged.
5.4 Fault Diagnosis:
■ FAST FLICKER (8 ashes per second or
more): The smoke head has detected
poor charging contacts. Clean the
contacts on both the cradle and the
smoke head feet and replace on charger
■ LED NOT ILLUMINATED: Return the
Smoke head to Charging Cradle. LED
should display according to Charging level
required.
■ LED NOT ILLUMINATED WHEN
SMOKEHEAD IS ON CHARGING
CRADLE: Check that the smoke head is
correctly seated on the charging cradle.
The smoke head has twin connectors on
each insulated foot, and may be
connected either way round.
Check the charging cradle is connected to the
240V AC mains
Check that the sprung connectors that
transmit the charging current on the
charging cradle are clean and not stuck in
a depressed condition.
Check that the charging connectors on the
insulated mounts on underside of the
smoke head are clean and free of dirt and
obstructions.
To check the charging voltage at the
charging cradle:
■ Connect a digital multi-meter set to
measure up to 30V DC to the two
charging
■ Connectors on the charging cradle and
depress the central charging switch
■ A voltage of 28V to 30V DC should
register on the multi-meter display
