Troubleshooting tcpO
2
/tcpCO
2
Problems
This section describes how to troubleshoot and correct faults associated with the tcpO
2
/tcpCO
2
module. The procedures for recognizing, isolating, and correcting faults using this module are as
follows:
• Identifying a problem based on visual indications or repeated INOPS.
• Checking the tcpO
2
/tcpCO
2
task window for specific error messages and performing the
corrective actions suggested in the table given with this module.
• Calibrating the module as required.

are displayed for the tcpO
2
/tcpCO
2
module, perform
the following actions:
6WHS
Make sure there is a transducer connected to the module. If no transducer is con-
nected, connect one.
6WHS
Make sure the tcpO
2
/tcpCO
2
parameter is turned on. Turn it on, if it is not.
6WHS
Make sure the tcpO
2
/tcpCO
2
numeric is turned on. Turn it on, if it is not.
6WHS
Make sure you don’t have more than one tcpO
2
/tcpCO
2
module plugged into the
module racks you are using. If more than one tcpO
2
/tcpCO
2
module is plugged in,
the supernumerary modules are ignored and should be removed.
6WHS
Check the connection on the module and the rack interface.
Unplug and re-plug the tcpO
2
/tcpCO
2
module and check if the green LED on
the tcpO
2
/tcpCO
2
module lights up after re-plugging. If it does not, proceed
with the following:
Put the tcpO
2
/tcpCO
2
module into another slot and check the LED once again.
If it lights up now, the connector for the previous slot is faulty and the rack
needs to be replaced. If it does not, proceed with the following:

Replace the cable from the Satellite Rack to the function box. Again unplug
and re-plug the tcpO
2
/tcpCO
2
module and check if the LED lights up. If it does
not, proceed with the following:
Plug any other (not faulty) module into the same slot and check if the LED
lights up. If the LED of the alternative module lights up, the tcpO
2
/tcpCO
2
module is defect and has to be replaced. If it does not, either the rack or the
rack interface card is defect. Proceed with the following:
