J.M. Description of Revisions This document was created. • • • • • • • • • • • • • • • • Added section 1- DOCUMENT RELEASE PROCESS. Removed 6.8 controlled cool down flowchart Update 8.5 section title to HEAT CONTROL AND DIAGNOSTICS and update HEAT ONE BURNER and HEAT TWO BURNER to reflect name change. Removed 12.2 water valve output test flowchart changed terminology in the PROGRAM MODE flowchart from "currency location" to "vending parameter." Corrected flowchart table of contents to include SWITCHING CYCLE flowchart. Added TEST BOOTH FLOWCHART to 14.1. Updated table of contents to reflect new section numbers. corrected COIN READY MODE flowchart, bottom pocket applying power up credit function was out of sequence. Updated PROGRAM MODE and OPL READY MODE flowcharts to reflect exiting program mode with the key pad, when control is in opl mode and had entered program mode using the UP and STOP keys. Added 30 sec fault resetting to exhaust and axial probe faults. updated REVERSING and ROTATION SENSOR DIAGNOSTICS flowcharts to handle new reversing diagnostics. Also added new REVERSING ROTATION SENSOR DIAGNOSTIC routine. Updated CYCLE START UP, WRINKLE GUARD, and S.A.F.E./ F.S.S. ACTIVATED flowcharts to reflect "active drive" instead of "drive" due to new reversing rotation sensor diagnostic routine. added NON CATASTROPHIC FAULT ROUTINE and updated HEAT CONTROL AND DIAGNOSTICS, added HEAT OFF DIAGNOSTICS routine and updated HEAT ONE BURNER SYSTEM, HEAT TWO BURNER SYSTEM, FAULT ROUTINE, HEAT CONTROL DIAGNOSTIC, COOL DOWN, PAUSE MAIN DOOR, LINT DOOR AND SAIL SWITCH OPEN flowcharts to reflect new HEAT OFF DIAGNOSTIC routine. Updated HEAT ROUTINE to reference BURNER SETUP setting. Date Released To MEC 9/13/04 To MEC 10/12/04 Page 2 of 84 CONFIDENTIAL: PROPRIETARY PROPERTY OF AMERICAN DRYER CORPORTATION ADC PHASE 8.4.1 CONTROL BOARD SOFTWARE FLOWCHART ADC ENGINEERING CONTROLS GROUP • • • • • • • • • • • • • • • • • • • • ADC CATALOG #: ADC0007 corrected terminology used to describe OPL-AUTO CYCLE flowchart. changed LOW VOLTAGE DIAGNOSTICS to POWER LOSS DIAGNOSTICS change S.A.F.E. SYSTEM to just S.A.F.E. and correct all occurances of SAFE to S.A.F.E. Removed ERROR ERROR for Registration Routine flowchart added CLEARING ESCROW Routine and added routine call to READY MODE ROUTINE. corrected grammar and spelling errors throughout flow chart, all changes are in RED. added INTERPOSING RELAY routine and updated WRINKLE GUARD, CYCLE DONE, and CYCLE START UP. Updated POWER UP flowchart to reflect that the language file should be loaded before displaying any message. changed all mentions of FAN to FAN/HOUR LOGGER, so that any time the FAN turns on the hour logger should also be on. updated Cycle start up, removed dual motor option and model diagnostics in cycle start up, reorganized to make more efficient. removed DISPLAY DIAGNOSTICS flowchart reorganized REVERSING to make more efficient. added Model Fault monitoring to Drying Diagnostics updated heat control and diagnostics, complete restructuring of routine. routine will now account for different model types and will check for latched relay first. Added belco drive output option to CYCLE START UP, REVERSING, COIN/FREE CYCLE RUNNING STATE, OPL- AUTOCYCLE, OPL MANUAL CYCLE, AND ROTATION SENSOR DIAGNOSTICS. added belco burner option to HEAT TWO BURNER SYSTEM. added automatic view cycle to OPL READY MODE. added non catastrophic fault call from coin handling. added fault handling of BURNER RETURN VOLTAGE and LATCHED HEAT RELAY to FAULT ROUTINE to handle the drive and fan shutting off due to the opening of the interposing relay. removed DEMO mode, this feature is better covered in ADC0006 PROGRAMMING MENU DOCUMENT Page 3 of 84 CONFIDENTIAL: PROPRIETARY PROPERTY OF AMERICAN DRYER CORPORTATION ADC PHASE 8.4.1 CONTROL BOARD SOFTWARE FLOWCHART ADC ENGINEERING CONTROLS GROUP ADC CATALOG #: ADC0007 and ADC0009 ADC DISPLAY USER INTERFACE. 1.2 J.M. • • • • • • • • • • • • Added MAINTAIN HEAT routine. Made changes to HEAT ONE BURNER SYSTEM AND HEAT TWO BURNER SYSTEM to call MAINTAIN HEAT. Made changes to HEAT CONTROL AND DIAGNOSTICS to account for EXH HIGH LIMIT or BURNER HIGH LIMIT issues and to release heat control while in the radiant sensor diagnostics if another BURNER is calling for heat. Added OUTPUT REVERSING MODE and DIRECTIONAL REVERSING MODE routines and updated REVERSING to include calls to these functions. THESE FUCTIONS ARE NOT FINISHED AT THIS TIME. MORE CHANGES ARE NEEDED WHICH WILL EFFECT ROTATION SENSOR FAULTS AS WELL. Corrected EXHAUST PROBE DIAGNOSTICS AND AXIAL PROBE DIAGNOSTICS in regards to fault self clearing to take into account the 3 minutes of fault cool down. Made changes to HEAT CONTROL AND DIAGNOSTICS to take into account cycle temp setting being reached before heat is successfully ignited. Removed INTERPOSING RELAY ROUTINE, and update CYCLE START UP, WRINKLE GUARD AND CYCLE DONE to just open or close the relay. Updated HEAT OFF routine to coincide with the changes that were made to the other heat routines. Changed messaging in the CYCLE DONE and WRINKLE GUARD routines to reflect latest software changes, also clarified the credit handling in these two locations. Added HEAT OFF DIAGNOSTIC routine calls to READY MODE DIAGNOSTICS, DRYING DIAGNOSTICS and WRINKLE GUARD DIAGNOSTICS Updated HEAT ONE BURNER SYSTEM, HEAT TWO BURNER SYSTEM, HEAT CONTROL AND DIAGNOSTICS , COOL DOWN , PAUSE, MAIN DOOR DIAGNOSTICS, LINT DOOR DIAGNOSTICS,SAIL SWITCH OPEN AND FAULT ROUTINE to combine the turn off heat command and the call for HEAT OFF DIAGNOSTICS. Made changes to HEAT 1 BURNER SYSTEM and HEAT 2 BURNER SYSTEM to account for axial thermistor temperature when deciding the need for heat in a cycle. To MEC 12/06/04 Page 4 of 84 CONFIDENTIAL: PROPRIETARY PROPERTY OF AMERICAN DRYER CORPORTATION ADC ENGINEERING CONTROLS GROUP ADC PHASE 8.4.1 CONTROL BOARD SOFTWARE FLOWCHART • 1.3 J.M. 1.4 ?? 1.5 S.G. TO MEC 12/13/04 ?? – Unsure what has been updated in this revision. To MEC 5/17/05 • To MEC 6/2/05 • • • • • A.L. S.G. Updated Lint Cleaning Routine to no longer show every 2 minutes in a drying cycle, the control will constantly show the message CLEAN LINT. • made changes to the HEAT DIAGNOSTIC AND CONTROL routine to account for excessive heat relay cycling while also providing some level of auto recoverability. • NOTE: Directional reversing is still not complete. • 1.6 ADC CATALOG #: ADC0007 • • • Made changes to the HEAT CONTROL AND DIAGNOSTIC routine to remove the option to have only one pockets heat turn on at a time & to remove a functions that created relay chatter. Added a note to the ADC WEB ADDRESS that states that the web address timer is reset when not in ready mode. Reviewed MODEL DIAGNOSTIC to see if electric model was accounted for. Electric model fault is covered in HEAT CONTROL AND DIAGNOSTIC. Corrected OUTPUT REVERSING MODE. The stop timer was being ignored after it had been started. Updated DIRECTIONAL REVERSING MODE. This section was currently incomplete. Removed ENERGY SAVING routine. Added an exhaust temperature limit of 120 when the Belco drive option is “disabled”. Format and grammar changes Corrected 13.1 FSS monitoring. Added description of OPL auto cycle Note: The latest revisions will be identified with RED text color formatting. Document changes that do not affect software functionality, such as document formatting, will not be indicated.
