Trouble-shooting chart

It is assumed that the instrument and its installation have been checked for power supply
health, integrity and correctness of wiring and mechanical damage.
If there is any doubt regarding interpretation of these instructions or the corrective actions
to be taken, contact your local MTL Gas sales office for clarification.
KIM = Katharometer Identity Module (see photograph on next page).
SYMPTOM POSSIBLE CAUSE
1. No power.
2. Fuse blown
Instrument appears to be
"dead".
3. Internal connection
failure.
1. Wrong supply
Instrument repeatedly
blows fuses.
2. Wrong value or type
of fuse.
1. Unexpected gas

3. Electronics failure.
Fault codes 64 to
131072 will only occur
during calibration.
1. Following a sensor 1. Sensor and KIM are

5. Fault code remains. 5. Electronics failure.
NOTE
TEST
1. Check power on
supply terminal.
2. Check main fuse in
AC power terminal block
- see Figure 5.
3. Disassemble and
check all connections.
1. Check actual voltage
voltage. supply with that shown
on the analyser data
label.
2. Check instrument
data label for correct
fuse.
1. Pass air through the
analyser.
2. Clean sensor as per
sections 7.5/7.6
3. Replace electronics
as per section 7.9
1. Check that serial
numbers match – see
Fig. 4 in manual for
location of KIM
2. Check gas - replace
as necessary - and flow
for at least 10 minuets
at the correct flow rate
- refer to calibration
section in manual
contaminated.
ACTION
1. Reinstate if
necessary.
2. Replace if necessary,
check supply voltage is
correct. If fuse blows
again see next symptom.
3. Replace KK650
electronics –
see section 7.9
1. Contact your
local MTL Gas
sales office.
2. Replace as
necessary.
1. Check to see if faults
still exist, if not, check
cause 2 then 3.
2. Check fault status,
if OK recalibrate
instrument.
3. Recalibrate
instrument.
1. Replace/exchange
as necessary.
2. Try to recalibrate
instrument.
3. Reset factory
settings – see section
7.10.2 and try to
recalibrate.
4. Clean sensor as per
sections 7.5/7.6 and
recalibrate.
5. Replace electronics
assembly as per
section 7.9
