Troubleshooting
Introduction
This section provides information that can be helpful in troubleshooting the monitor.
Screen messages
Messages may appear on the display to inform the operator of some condition requiring
operator or service attention. Messages that indicate that the Propaq CS monitor may
need servicing are listed below. For information about other messages, refer to the
Propaq CS Directions For Use.
PROGRAM FAULT: SETTINGS LOST, TIME/DAY RESET. If this message appears when
the monitor is first turned on, it generally indicates a drained battery. The monitor can be
used, but the time and date and all other settings will return to factory defaults each time
the monitor is turned off. Replace the battery as soon as possible and reprogram the time,
date, and other settings according to the Propaq CS Directions For Use.
CUFF FAULT: NIBP DISABLED, SERVICE REQUIRED. A single fault was encountered in
the NIBP system. Perform a functional check and calibration or repair as needed.
CALIBRATION ERROR, TEMP DISABLED. This message appears when the monitor has
detected that temperature circuitry is out of calibration. The temperature channel is
disabled until the monitor is repaired. There are no temperature channel adjustments; the
temperature channel uses a regulated power supply as a reference. Check all power
supply values (
“Main power supply adjustments” on page 48). The Analog board may
need to be replaced.
SENSOR FAILURE - EEPROM - (MCO
2
). A failure in the sensor EEPROM is detected
(typically a checksum error). The CO
2
channel is disabled until the sensor cable is
disconnected. Replace the sensor.
SENSOR FAILURE, HEATER - (MCO
2
). A failure in the sensor temperature control
hardware is detected. This is typically a sensor error, but may be an MSP board fault.
Replace the sensor or MSP board as required.
SENSOR FAILURE, MOTOR DRIVE - (MCO
2
). The mainstream sensor motor drive
hardware has failed. The channel is disabled until the sensor is disconnected. Replace the
sensor.
DEGRADED WAVEFORM, CHECK ADAPTER - (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.
