Troubleshooting Pressure Problems
This section describes how to troubleshoot and correct faults associated with the M1006A and
M1006B Pressure plug-in modules. The procedures for recognizing, isolating, and correcting
faults with this module are as follows:
• Identifying a problem based on visual indications or repeated INOPS.

❏ IfQHLWKHUQXPHULFVQRUD" are displayed for the PRESSURE 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 PRESSURE parameter is turned on. Turn it on, if it is not.
6WHS Make sure the PRESSURE numeric is turned on. Turn it on, if it is not.
6WHS If you want to measure CPP, make sure that one PRESSURE parameter is labeled
ICP and both pressures display valid numerics.
6WHS Make sure you don’t have too many PRESSURE module plugged into the module
racks you are using. If too many PRESSURE modules are plugged in, you get two
status messages: “Too many modules of the same type connected” and “Currently
ignored module in rack position x.x”. The last message enables you to identify the
supernumerary module.
These modules are ignored and should be removed.
6WHS Check the connection on the module and the rack interface.
 Unplug and re-plug the PRESSURE module and check if the green LED on the
PRESSURE module lights up after re-plugging. If it does not, proceed with the
following:
 Put the PRESSURE 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 PRESSURE
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 PRESSURE
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:
