• Display Test All indicator LEDs are illuminated and ‘8.8.8.’ is displayed on the Airway Temperature display · Model Number eg ‘730’ · Software Version Number eg ‘2.0’ · Temperature Control Setting eg ‘37.0’ is displayed • Chamber Control setting If heater wire mode is selected then the chamber control setting is displayed eg ‘-1.0’. Not applicable for MR480 · Maximum Heaterplate setting eg ‘110’ · Audio Beep 2.4 HEATER WIRE ON MODE (ALL MODELS EXCEPT MR480) In the Heater Wire On Mode (heater wire switch green LED on) the heaterplate and heater wire are regulated to maintain the desired temperature and humidity, within close limits. To minimise rainout or maximise humidification, the chamber outlet temperature can be adjusted to control at a fixed offset from the set airway temperature. The front panel Chamber Control knob is used for this purpose, see § 2.1.2 above. 2.5 MR730/720 IN HEATER WIRE OFF MODE AND MR480 In the non Heater Wire mode of the MR730/720 (heater wire switch green LED off) the delivery temperature is maintained by heaterplate control only. The sensor at the delivery hose end controls the heaterplate to deliver the selected temperature. The sensor at the chamber outlet is employed in a backup safety mode, to limit the chamber outlet temperature to a maximum of 66 °C. In this way safety at low flow rates (below 5 l/minute) is enhanced at the sacrifice of some low flow performance. Ref. 185040646 MR730/720/700/480 Technical Manual . Revision F . Issued March 2001 5 2.6 WARM UP MODE After initial turn on, warm up mode is entered. In this mode the Low temperature alarm is disabled. The Low temperature alarm is enabled when warm up mode is exited. 2.6.1 WARM UP MODE EXITING CONDITIONS (LOW TEMPERATURE ALARM ENABLED): · (MR700/MR730(All versions) and MR720(version 1.0) in Heater Wire Mode) Warm Up mode continues until the Software Detects- Either: The airway temperature reaches within 0.8 °C of the Temperature Control set point. Or: The airway temperature has not increased by 2 °C for at least 4 minutes (2 minutes for version 3.0 software). Or: The airway temperature has not got within 2 °C of the set point after ten minutes from switch on. · (MR700/MR730(all versions) and MR720(version 1.0) in Non Heater Wire Mode and MR480) Warm Up mode continues until the Software Detects- Either: The airway temperature gets above 30 °C. Or: The airway temperature has not increased by 2 °C within 15 minutes. Or: The airway temperature has increased by 2 °C within 15 minutes but still has not reached 30 °C after a further 15 minutes. Note:In this mode the audio alarm is not enabled until 30 seconds after the Airway Temp Low LED switches on. At this time the heaterplate circuit switches off, pressing mute will silence the alarm for 10 minutes, during which time the heaterplate power is enabled 2.6.2 MR720 (VERSION 2.0, 3.0 SOFTWARE) If the above warm up exiting conditions are not initially met the MR720 will automatically enter the standby mode for 20 minutes for version 2.0 software and 30 minutes for version 3.0 software (refer § 2.7.2). 2.7 STANDBY MODE 2.7.1 MR700/MR730 (ALL SOFTWARE VERSIONS), MR720 (VERSION 1.0 ONLY) The standby mode can be entered or exited by depressing the standby button for 1 second. A beep will be emitted once successful entered or exited standby mode (refer § 2.2.3). In the standby mode all Low Temperature alarms are inhibited, the heaterplate is controlled to a nominal 40.0 °C and the heater wire is on a 15 % duty cycle. Standby mode is automatically exited after 20 minutes (30 minutes for version 3.0 software) and the warm up mode is entered (the low temperature alarms remain disabled - refer § 2.6). A Remote Standby request (see Appendix A5.3) enables the standby mode and turns the standby amber LED permanently on. 2.7.2 MR720 STANDBY MODE (VERSION 2.0 AND 3.0 SOFTWARE ONLY) The MR720 has a special feature where it will go into a standby mode automatically after turn on if the warm up exiting conditions are not met. This standby mode time is 20 minutes for version 2.0 and 30 minutes for version 3.0 software. While in standby mode, if the airway temperature increases by 2 °C at any time, the MR720 will exit stand by mode and enter warm up mode. The unit then monitors the warm-up exiting conditions(see § 2.6.1 and 2.6.2), and if these are not met, then the unit re-enters Standby mode. Ref. 185040646 MR730/720/700/480 Technical Manual . Revision F . Issued March 2001 6 3.0 ALARMS AND INDICATORS _____________________________________ 3.1 TEMPERATURE PROBE ALARM If the airway temperature probe is disconnected or develops a low or high resistance the Temperature Probe alarm will be enabled. Indication is by a ‘- - -' message on the airway temperature display plus a flashing Temperature Probe red LED and an audio alarm. Five specific fault types can be diagnosed and are displayed by the sequence of ‘decimal points’ in the display, as shown below: a - - -Temperature Probe not plugged in...
