6WHS Perform a Self-Test (See “Performing the CO2 Module Self-Test” on page 5-44). If
the CO
2
test numerics read exactly the listed values, proceed to the next step, if not,
replace the module.
6WHS Refer to the following table. Correct the possible cause identified by the INOP
message and verify that the INOP disappears. If the problem still exists, replace the
module.

UNPLUGGED CO
2
module is unplugged from
the rack.
Perform Step 5 on page 5-21.
CO

EQUIPM MALF Malfunction in the transducer or
module.
Replace transducer. If INOP persists
replace module.
CO

NO TRANS-
DUCER
No Transducer is connected to the
module.
Connect transducer to module.
Run a calibration as described in CO
2
Module section of the 8VHU¶V5HIHUHQFH
0DQXDO.
(If the transducer is replaced, the new
transducer must be re-calibrated.)
CO
2
FAILED CAL Calibration aborted due to power
failure, unstable signal during
calibration, or transducer being
placed on the wrong cal cell.
Run a calibration as described in CO
2
Module section of the 8VHU¶V5HIHUHQFH
0DQXDO.
Make sure that calibration cell is
changed when prompted.
If INOP persists replace module.
CO

The transducer has not reached
operating temperature.
Wait until transducer has warmed up.

CAL RUNNING The CO
2
calibration is running. Wait until calibration is finished.
CO

CAL MODE Cal mode is set but the calibration
has not been initiated.
Perform accuracy check or start a cali-
bration as described in CO

Module sec-
tion of the 8VHU¶V5HIHUHQFH0DQXDO.
