Description
O2 sensor
offset too
high
System
error,
open
The error can only occur during an O2 sensor calibration. An error reset can be
carried out by the user. A successful re-calibration also resets the error.
Possible causes
: defective false test gas (not applicable with test air), test gas
flow too low, O2 sensor defective.
O
2
sensor
slope too
low
System
error,
open
The error can only occur only during an O
2
sensor calibration. An error reset can
be carried out by the user. A successful re-calibration also resets the error.
Possible causes:
Incorrect calibration gas, test gas flow too low, probe filter
damaged, filter head missing, faulty O
2
sensor.

be carried out by the user. A successful re-calibration also resets the error.
Possible causes:
Incorrect calibration gas, O

System
error,
open
The error can only occur only during an O
2
sensor calibration. An error reset can
be carried out by the user. A successful re-calibration also resets the error.
Possible causes:
test gas flow too low, probe filter is damaged, process
pressure fluctuations too high.
COe board
communicatio
n error
20.80mA
unless set
otherwise
The error can occur at any time and signals a failure in communication between
the display circuit board and the COe circuit board. A reset can be carried out by
the user. If the error occurs again, switch the system on and off. If the error
persists after restarting the system, contact an ENOTEC service point.
COe sensor
heater short
circuit
20.80mA
unless set
otherwise
The error can occur at any time and signals a short circuit either by COe sensor
heating or within the connection between the electronic unit and COe sensor. A
reset can be carried out by the user.
Possible causes:
Short-circuit of the COe
sensor heater cable at the terminal points of the electronics or the sensor, short
circuit within the probe cable, short circuit inside the COe sensor
COe sensor
heater short
circuit
20.80mA
unless set
otherwise
The error can occur at any time and signals a break in the circuit of COe sensor
heater. A reset can be carried out by the user, once the fault has been remedied.
Possible causes:
contact problems between COe sensor cable and terminal
points of the electronics respectively the probe, probe cable is damaged, defective
COe sensor
Open circuit
COe sensor
heating
20.80mA
unless set
otherwise
The error can occur at any time and signals a break in the circuit of COe sensor. A
reset can be carried out by the user, once the fault has been remedied.
Possible
causes:
contact problems COe sensor wire to the terminal points of the
electronics and the probe, probe cable is damaged, defective COe sensor
Open circuit
COe sensor
20.80mA
unless set
otherwise
The error can occur at any time and signals a failure of the electronic components
of the COE board. A reset cannot be carried out by the user. If the error persists
after restarting the system, contact an ENOTEC service point.
COe board
hardware
error A-C
20.80mA
unless set
otherwise
COe sensor calibration failed for one of the following reasons. A reset cannot be
carried out by the user. All entries triggered by this error will then also be deleted.
COe sensor
calibration
failed
20.80mA
unless set
otherwise
COe sensor calibration failed for one of the following reasons. A reset cannot be
carried out by the user. All entries triggered by this error will then also be deleted.
COe sensor
offset too
low/high
20.80mA
unless set
otherwise
The error can only occur only during COe sensor calibration. A reset cannot be
carried out by the user. A successful re-calibration remedies the error. Possible
causes: insufficient supply of reference air.
COe factor
alpha/beta/
gamma
invalid
20.80mA
unless set
otherwise
The error can only occur only during COe sensor calibration. It can be reset by the
user. A reset cannot be carried out by the user. A successful re-calibration also
remedies the error.
Possible causes:
inadequate reference air supply, process
pressure is too high, incorrect test gas (not test air), Coe sensor defective.
Error
ENOTEC
REMOTE
module
System
error,
open
Indicates a hardware error of the ENOTEC REMOTE
module.
Possible cause:
the ENOTEC REMOTE
module is defective.
Unlisted errors: Other errors cannot be remedied by the customer.
