cGas Detector Analog Transmitter - Operation Manual
List of Possible cGas Error Codes:
(appears on the display in place of the units for a channel)
CODE
DESCRIPTION
F01
Negative Fault
Reading
Check to make sure the smart sensor board
is present and installed properly in the socket.
If installed, the cGas detects the sensor signal
is too far below its zeroAD. May be caused
by a sensor that is temperature or humidity
sensitive. Zeroing the sensor will normally
resolve this.
F02
Smart Board
Fault
cGas cannot communicate with the smart
board. Ensure the smart board is installed
and installed on the correct side (left) if a
single channel unit. Otherwise power cycle or
replace the sensor smart board.
F03
CO2
Communication
Fault
cGas cannot communicate with the CO
2
sensor even though it can communicate with
the smart board. Power cycle or replace the
sensor smart board.
F04
POT chip has
failed
The internal smart sensor board gainPOT chip
has failed. If a power cycle does not resolve
this, replace the sensor smart board.
F05
Error in reading
Smart Board
cGas detected an error in the smart board
ID. Use “Write to Sensor” for the indicated
channel (passcode 3022).
FO6
SB ID Mismatch
Firmware expected a different smart board
than what is in the sensor socket.
