Indication of Errors

A malfunction in the GRAPHIX Controller is displayed by an error message on the screen
or issued by an error number via the serial interface. Additionally, an entry is made into the
error memory list, from which the 20 most recently registered errors can be displayed on the
screen ( Chapter 6.2 Error Log, page 17) as well as read out via serial interface. The
following tables give a survey on all recognisable sensor errors

( Table 7, page 16) and
Cause and remedy
Attached sensor is recognized and
in the specified measuring range.
Error in the electric circuit of sensor
identification.
Identification resistor of sensor
identification unknown or missing.
Fault affecting the connection to the
sensor. The message will only be
displayed in the display field of the
affected measurement
Acknowledge this message by
selecting and terminating
channel menu at the corresponding
channel.
The measurement signal from the
sensor is significantly above the
permissible range.
The measurement signal from the
sensor is significantly below the
permissible range.
Communication error. Failure in the
data transfer to IONIVAC sensors of
ITR90, ITR200 and CTR-N series.
Electronics/EEPROM
IONIVAC sensors of ITR200 series.
Pirani error with IONIVAC sensors
of ITR90 series.
Hot cathode error (both filaments
defectively) with IONIVAC sensors
of ITR200 series.
Hot cathode error (filament 1
defectively) with IONIVAC sensors
of ITR200 series.
Pirani error with IONIVAC sensors
of ITR90 series.
Pirani adjustment deficient with
IONIVAC sensors of ITR90 series.
