E-module issues
PSM module issues
Possible cause
Recommended action
Incompatible module
Refer to the patient monitor’s supplemental information manual document
to see the list of compatible modules.
DC/DC board failure
The supply voltages for the E-module interface board are generated in the
DC/DC board. Check that these supply voltages are within specs, see
section
Hardware statistics for:
- VSYS voltage (mV)
- +15V MOD voltage (mV)
If any of the output voltages are out of spec, the problem is most likely in the
DC/DC board. Replace the DC/DC board.
The hinge flex board is loose or
faulty.
Check that the hinge flex board is intact and properly connected to the CPU
board and to the E-module Interface board.
E-Module interface board failure. The E-module interface board creates the supply voltages
+ 15 VD, + 15 Va, - 15Va and + 5 Vmod) for the connected E-modules.
Replace E-module interface board, if suspected faulty.
CPU board failure
The RS-485 communication for the E-modules is managed by the EMBC
section of the CPU board.
- Check EMBC Frame logs for possible EMBC failures, see section
.
If the cause is none of the above, the problem is most likely in the CPU
board. Replace the CPU board.
Possible cause
Recommended action
Pole mount cable loose or faulty (if
the PSM module is mounted to a
pole mount)
Check that the Module Bus Adapter for PSM and the connection cable is
intact and properly connected to the PSM module mounted to the IV pole
and to the PSM connector in the patient monitor.
DC/DC board failure
The +15VMOD supply voltage for the PSM module is generated in the DC/
DC board. Check that it is within specs, see section
for:
- +15VMOD voltage (mV)
If +15VMOD voltage is out of spec, the problem is most likely in the DC/DC
board. Replace the DC/DC board.
The hinge flex board is loose or
faulty.
Check that the hinge flex board is intact and properly connected to the
CPU board and to the module frame flex board.
The module frame flex board is
loose or faulty.
Check the status of the +15 VMod PSM voltage, see section
Hardware statistics.
If the +15 VMod PSM voltage is out of spec, but the +15VMod exists in the
DC/DC board and hinge flex board is good, the problem is most likely in the
module frame flex board.
