3.4.3"SEE MANUAL" INDICATOR

The "See Manual" indicator displays two fault types:

Hardware Fault. The "See Manual" indicator flashes off and on. Briefly pressing the Temperature Setting button briefly produces a pattern on the three Temperature Setting Indicators, representing a fault code. Refer to § 5.2 for fault code definitions.

Microprocessor Fault. The "See Manual" indicator is on continuously.

3.4.4 HEATER-WIRE INDICATOR

3 The Heater-wire Indicator is located in the connector at the end of the heater-wire adaptor. If the heater- wire adaptor is connected to a compatible heated wire circuit then the green indicator will illuminate, and the heater-wire mode of operation is initiated.

If a heated circuit is connected and the Heater-wire Indicator does not turn on then a fault is present in either the heated circuit or the heater-wire adaptor, and non heater-wire mode of operation will be initiated.

Refer to § 5 for trouble shooting.

3.4.5AMBIENT TEMPERATURE SENSOR

Measures ambient air temperature for controlling the heating of the heated wire breathing circuits. Refer to § 3.5.1 for more information.

3.4.6CHAMBER DETECTION SENSOR

A thermistor is embedded in the third pin in the heater-wire connector. This thermistor senses the chamber type (reusable or single-use) by measuring the temperature of the gas exiting the chamber as it passes through the circuit elbow.
