service personnel, it is described in this chapter. System failure codes are described in this chapter.
6.1 Alarms
6.1.1 Compartment Sensor Failure Alarm
6.1.2 Patient Probe 1 Failure or Patient Probe 2 Failure Alarm
Cause or Circumstances
Failure
Action
The software detected a
difference in the two air
thermistors of > 0.5ºC.
Defective compartment air
probe or harness
Measure the resistance of the two
sensors at the harness from control
board J1, Pins 1-2, and 3-4. Under
stable conditions, the resistances
should be within about 100 ohms. If
defective, disassemble the air
probe assembly and disconnect the
5 pin connector inside. Measure
resistance of the two thermistors at
pins 1-2 and 3-4 to determine if the
sensor or harness is defective.
Defective control board.
If the thermistors and harness
measure OK, replace the control
board.
Cause or Circumstances
Failure
Action
Probe thermistors show
difference > 0.5ºC.
Defective patient probe
Replace patient skin probe.
Defective patient probe panel
connector wiring
Plug patient probe into probe panel
connector 1. In service Mode, note
the difference between readings
from P11 and P12. Plug the same
probe into probe panel connector 2
and note the difference between
readings from P21 and P22. If they
are greater there is resistance in
the probe panel connector harness.
Replace the harness.
