Troubleshooting Plug-
in Modules
Replace the rack and plug in the PRESSURE module into the new rack. If the
LED on the module does not light up, replace the rack interface card in the
function box.
❏ If a "LQVWHDGRIDQXPHULF and one or more INOP messages are displayed for the
PRESSURE module, perform the following actions:

6WHS Perform a module self-test (See “Performing the M1006A/B Pressure Module Self-
Test” on page 5-42). If the PRESSURE 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.

<Px> UNPLUGGED Pressure module is
unplugged from the rack.
Perform Step 6 on page 5-10.
<Px> NO TRANSDUCER No transducer connected to
the module.
Connect transducer to module.
<Px> EQUIP MALF Malfunction in the pressure
hardware.
Replace module.
<Px> ZERO + CHECK CAL Occurs when new trans-
ducer attached to module, or
when the power is off for
longer than one minute and
settings transfer is off.
Zero the PRESSURE module.
<Px> OVERRANGE Measured pressure >361
mmHg, <-41 mmHg.
Replace transducer.
If the INOP persists, replace module.
CPP CHECK SOURCES Occurs for one minute if
either the arterial or the
intracranial pressure sources
are switched off, or the front
end modules are removed.
Connect module properly to rack and
make sure that the PRESSURE parame-
ter is turned on.
Make sure you get valid numerics for
ICP and the other pressure. Make sure
that the preselected pressure label in the
CPP source window is the same as for
the second pressure.
CPP CHECK UNITS Occurs if two pressure
sources have different units.
Use the same unit for all PRESSURE
modules.
