Heater plate triac circuit faulty. E30 Power (on/off) button stuck on E31 Mute button stuck on E32 Mode button stuck on E40 Unit not functional tested at time of manufacture MR850 Technical Manual * Revision J * Issued November 2005 * Ref. 185041340 (185041713 internal) Error Description of Fault E41 Failed the functional test at time of manufacture E42 Was not stress tested during manufacture E43 Failed the stress test during manufacture E44 Not tested on functional tester 2 E45 Failed production functional tester 2 E4A EEPROM write error occurred E4B EEPROM write verify error occurred E4C EEPROM read error occurred E50 Flow circuitry not functioning E51 Flow circuitry shorted on MR850 Technical Manual * Revision J * Issued November 2005 * Ref. 185041340 (185041713 internal) 6.4 Diagnostic Menu By pressing the mute and mode buttons together for 1 second, the diagnostic menu is entered, indicated by the display of two rows of dashes ‘= = =’. Releasing both buttons will allow the diagnostic menu to cycle automatically through the menu, pausing at each function. Pressing the mute button at this time will display the value behind each function for as long as the mute button is held. 6.4.1 Diagnostic Menu for Software Versions 5.45 & 5.70 Display Description TC Temperature Compensation (TC) algorithm ‘---‘ = 0.0 °C of chamber compensation. ( CSP = 37.0 °C) ‘Lo ’ = 1.5 °C of chamber compensation. ( CSP = 38.5 °C ) ‘Hi ’ = 3.0 °C of chamber compensation. ( CSP = 40.0 °C ) To change the TC value the press the Mute and Mode buttons together for 1 second. The humidifier will confirm the change with a double-beep.

To clear LAS, press and hold the mute and mode buttons for 1 second. The humidifier will beep when LAS has been cleared. LFS Last Humidifiers Fault State, refer to section 6.3. To clear LFS, press and hold the mute and mode buttons for 1 second. The humidifier will beep when LFS has been cleared. SoF Software version End Press the mute button to cycle to the start of the menu, or the diagnostic menu will automatically exit after 6 seconds MR850 Technical Manual * Revision J * Issued November 2005 * Ref. 185041340 (185041713 internal) 6.4.2 Diagnostic Menu for Software Version 6.00 Display Description HC Humidity Compensation (HC) algorithm Invasive mode, compensation range is 0.0 to 3.0 °C ( CSP = 37.0 to 40 °C ) Non-Invasive mode, compensation range is 0.0 to 5.0 °C ( CSP = 31.0 to 36.0 °C ) By pressing the Mute and Mode buttons together for 1 second or pressing the Mute and Power buttons together for 1 second the user can respectively move up or down through the settings listed below. The humidifier will confirm the change with a double-beep. ‘5.0’ = +5.0 °C of chamber compensation (Non-Invasive mode only) ‘4.0’ = +4.0 °C of chamber compensation (Non-Invasive mode only) ‘3.0’ = +3.0 °C of chamber compensation ‘2.0’ = +2.0 °C of chamber compensation ‘1.0’ = +1.0 °C of chamber compensation ‘0.0’ = +0.0 °C of chamber compensation (NO compensation) ‘-A-‘ = Automatic humidity compensation mode: Invasive mode: 0 to 3 °C in 0.5 °C steps Non-invasive mode: 0 to 3 °C in 0.5 °C steps CSP Chamber set point, in 0.1 °C resolution eg: 37.0 Invasive mode range 35.5 to 40 °C. Non-Invasive mode range 31.0 to 36.0 °C.
