SYMPTOM
ORIGIN / DIAGNOSTIC
CONFIRMATION
REMEDY
Helium signal or inlet pressure
analog display abnormally lit
Wrong connection between remote
control and control panel
n
Secure proper connection of the
-
remote control, stop leak detector
and start again
Remote Control keys inactive
Remote control disconnected (no LED
and display on the remote)
Autocal key deactivated (Beep
emitted when Autocal key is pressed)
31
Start-up autocal. failure
Filament status OFF
Peak fault
Analyzer cell incorrect assembly
n
Secure proper connection of the
remote control.
If remote control display is erratic,
after reconnection, stop leak
detector and start again
n
Leak detector is in test mode:
external calibration is available on
the control panel only
Stop test cycle to start an internal
autocalibration
n
Select filament status ON in the
spectro menu and start an autocal.
n
Check the analyzer cell
C 301
E 400
Autocal. failure: cal. Leak year
error
Temperature too low/ high:
autocal. failure temperature
limits
Incorrect internal calibrated leak
parameters
Temperature sensor disconnected
Ambient temperature
Fan(s) failure
n
Check and correct internal
calibrated leak parameters
n
Secure proper temp. captor
connection to the internal
calibrated leak
n
Make sure the leak detector is
used within ambient temperature
tolerance
n
Check fan status and replace faulty
fan(s)
C 305
A 800
-
Autocal. failure: helium pollution
High background (helium signal is
higher to the calibrated leak value
used for the calibration)
n
Degassing in the analyzer cell:
keep pumping the cell for 10 min
(in stand-by mode) and start an
autocalibration
If the trouble is not eliminated,
look for possible leaks or oil
contamination (for RVP)
E 750
Autocal. failure: peak locating
error
Problem of the calibration valve
Peak fault: internal calibrated leak
damaged (lack of helium)
Incorrect filament alignment
Peak fault: analyzer cell incorrect
assembly
n
Check valve VC3
n
Check internal calibrated leak
parameters
n
Check consistency between
measurement of the internal and
the external calibrated leak
n
Change internal calibrated leak
n
Check and adjust filament position
n
Check the analyzer cell
