56 Troubleshooting Welch Allyn Propaq CS Vital Signs Monitor
LACK OF WAVE, CHECK ADAPTER, SENSOR - (MCO
2
). The airway adapter (cuvette)
may be contaminated or the light source in the sensor may be faulty. Clean or replace the
cuvette as required or replace the CO
2
sensor.
SENSOR FAILURE, CALIBRATION ERROR - (MCO
2
). A Sensor failure has occurred.
Replace the sensor.
PUMP FAILURE, SERVICE REQUIRED - (SCO
2
). The sidestream pneumatic tubing is
kinked or a pump failure on the SSP board has occurred. Correct the tubing problem or
replace the SSP board as required.
DEGRADED WAVEFORM-SERVICE REQUIRED - (SCO
2
). This error indicates possible
contamination or light source failure in the CO
2
measurement chamber (bench) that is
located on the Stick board or by a failure of the SSP Board. Replace the Stick or SSP board
as required.
LACK OF WAVEFORM-SERVICE REQUIRED - (SCO
2
). This error indicates possible
contamination or light source failure in the CO
2
measurement chamber (bench) that is
located on the Stick board or by a failure of the SSP Board. Replace the Stick or SSP board
as required.
MOTOR FAILURE-SERVICE REQUIRED - (SCO
2
). The motor drive in the CO
2
bench has
failed. Replace the Stick board.
CALIBRATION ERROR-SERVICE REQUIRED - (SCO
2
). A CO
2
bench failure has
occurred. Replace the Stick board.
OCCLUSION-CHECK EXHAUST PORT/TUBING - (SCO
2
). Repeated error messages
after removing any occlusion on the exhaust connector can indicate a defective pump
located on the SSP board. Replace the SSP board.
Non-recoverable error codes
Non-recoverable errors are detected by software and indicate the Propaq CS monitor is no
longer able to function properly and must be returned to Welch Allyn for service. Contact
Welch Allyn Technical Support.
When a non-recoverable error is found, the software attempts to put the error message
and its number on the monitor display. All monitoring functions are locked out. Non-
recoverable errors are therefore distinct from equipment alerts, which permit reduced
monitoring capability.
Non-recoverable errors are indicated in the following format x - yyy -zzzz
where:
x = 0 indicates a problem found by the Display Control Processor (DCP).
x = 1 indicates a problem found by the Data Acquisition Processor (DAP).
x = 2 indicates a problem found by the Printer Control Processor (PCP) on the
Printer Main board.
x = 3 indicates a problem found by the SpO
2
Control Processor (SCP) on the
SCP board.
x = 5 indicates a problem found by the Main Stream Processor (MSP) on the
MSP (CO
2
) board.
