Description
O
2
sensor
offset too
high
System
error,
open
The error can only occur 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: defective false test gas (not applicable with test air), test gas
flow too low, O2 sensor defective.

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, faulty O
2
sensor.

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 CO
e
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.
CO

sensor
heater short
circuit
20.80mA
unless set
otherwise
The error can occur at any time and signals a short circuit either by CO
e
sensor
heating or within the connection between the electronic unit and CO
e
sensor. A
reset can be carried out by the user.
Possible causes:
Short-circuit of the CO
e
sensor heater cable at the terminal
points of the electronics or the sensor, short circuit within the probe cable, short
circuit inside the CO

sensor
CO

20.80mA
unless set
otherwise
The error can occur at any time and signals a break in the circuit of CO

heater. A reset can be carried out by the user, once the fault has been remedied.
Possible causes:
contact problems between CO

sensor cable and terminal
points of the electronics respectively the probe, probe cable is damaged, defective

Indicates a hardware error of the ENOTEC REMOTE
module.
Possible cause:
the ENOTEC REMOTE
module is defective.
Error Sample

2. 00 mA
Possible cause:
Indicates that the filter is blocked - Instrument air has failed -
Pneumatic cable damaged or not connected. Incorrect flow alarm set, blocked
filter.
Unlisted errors: Other errors cannot be remedied by the customer.
