On/Off Power Switch and Circuit Breaker:
(See Figure 3-1.)
The On/Off power switch is located on the left side of the controller assembly (as viewed
from the front) near the power cord socket. It is used for switching the power to the
warmer(On and Off). The switch is also a circuit breaker and limits the maximum current
drawn by the unit. If this circuit breaker trips when the warmer is operating, the power switch
is deactivated to the Off position. To reset the circuit breaker, return the power switch to the
On position. If the circuit breaker trips again, service is required.

D. Alarms
All alarms except system failure and power failure are preceded by a 30 second intermit-
tent operator prompt tone.
• Probe Failure Alarm
• Patient Temperature Alarm
• System Failure Alarm
• Heat Off Alarm
• Check Patient Alarm
• Power Failure Alarm
Probe Failure Alarm:
The probe failure alarm is only active in the servo mode of operation. The alarm activates
when the skin temperature probe fails electrically due to an open or short circuit, or is
disconnected from the Warmer. The heater deactivates and the patient temperature
display flashes “HH.H” or “LL.L” when this alarm condition exists.
Patient Temperature Alarm:
The patient temperature alarm is only active in the servo mode of operation. The alarm
activates when the difference between the patient temperature and the control tempera-
ture is greater than 1°C. When the patient temperature returns to within 0.8°C of the
control temperature, this alarm is automatically reset.
Note: If the patient temperature probe reads below 30°C or above 42°C in servo mode, the
heater is deactivated and “LL.L” or “HH.H” respectively, appears in the patient temperature
display.
Note: Qualified service personnel can adjust the alarm to trigger at a difference of 0.5°C
and reset at a difference of 0.3°C.
