5) Insert programmer line cord into wall outlet. Again, if plug does not match outlet, outlet must be replaced or unit can be wired direct. If wired direct, it must be done by a licensed and qualified electrician. NOTE: WHEN POWER IS FIRST APPLIED, THE PROGRAMMER ALARM WILL GO OFF FOR APPROXIMATELY TWO SECONDS.. 6) The display will alternately read [ ldLE ] and the current temperature in the furnace. 7) If the display does not read [ ldLE ], press “STOP” then press “ENTER”. 8) Turn the furnace control to HIGH and your installation is complete. Now you can start using the programmer. 9) To activate a program, refer to the operating instructions of our burnout furnaces. NOTE: EVEN THOUGH THE PROGRAMMER IS OFF AT THIS TIME, THE UNIT WILL DISPLAY THE AMBIENT TEMPERATURE INSIDE THE FURNACE. 5 PLACING FLASKS IN YOUR WW ELECTRIC BURNOUT FURNACE IMPORTANT NOTE: YOU MUST USE EITHER STEAM WAX ELIMINATION OR THE WAX ELIMINATION PROGRAM OF THE FURNACE. REMOVE THE WAX TRAY AFTER THE WAX ELIMINATION CYCLE HAS COMPLETED. FAILURE TO REMOVE THE WAX TRAY WILL CAUSE CARBON BUILD-UP ON THE EXPOSED ELEMENTS RESULTING IN PREMATURE ELEMENT FAILURE. THE ELEMENTS ARE NOT WARRANTED. When starting to load your furnace for wax elimination, be sure to use a tray to catch the melted wax. We highly recommend our WWT13 or WWT18 Furnace Grate & Tray for this purpose. Place flasks sprue hole down. Do not allow flasks to touch the sides, back or door of the furnace, nor to touch each other's sides. Above all, do not allow a flask to touch the thermocouple sensor located in upper center of back wall. When stacking flasks, be sure that the sprue hole is exposed at all times, so that no wax residue can be trapped. See illustration below. Flasks may touch edges (not sides) of each other as shown as long as the sprue holes are exposed. After the wax elimination cycle is complete, the flasks must be removed so that the wax tray can be removed, then the flasks can be returned to the furnace, sprue hole up and again, fully exposed and the firing procedure begun. NOTE: IF THE WWT13 OR WWT18 GRATE & TRAY IS USED, IT IS NOT NECESSARY TO TURN SPRUE HOLE UP AFTER WAX ELIMINATION. NOTE: THESE EXAMPLES SHOW CAPACITIES FOR OUR W18 FURNACE. THE SAME PRINCIPLES APPLY FOR ANY BURNOUT FURNACE. Stacking suggestions in 18x18x18 furnace for maximum capacity using different size flasks. NOTE THAT SPRUE HOLE MUST BE EXPOSED BOTH DURING WAX ELIMINATION (SPRUE HOLE IS DOWN) OR WHEN FIRING (SPRUE HOLE IS UP). 6 PROGRAMMER DISPLAY The WW Computerized Programmer Display prompts the operator with various readings. The display may appear peculiar due to the construction of each character in the standard LED display. Reading that appear on the display and their descriptions are as follows. DISPLAY DESCRIPTIONAbRT Abort The firing was stopped. ALAR Alarm ALAR appears either when you are entering an alarm temperature or when the alarm is sounding during a firing. To stop an alarm, press any key except STOP. If the alarm goes off when you first begin firing, it is because it was set for a lower temperature; than the present temperature. bAdP Bad Program This message appears when a Ramp-Hold firing has been programmed with 0 rate in the first segment. CFG Configuration This is an option that shows the factory configuration code for your Sentry. This is for technicians who call the factory for support. CHG-Change °F/°C Choose between operation in degrees F of degrees C. 7 CPLT Complete This means the firing completed as programmed. DELA Delay DELA is a timer that starts the kiln later. Delay time appears in hours and minutes. °F 1 Temperature This prompt which appears in Ramp-Hold programming, is asking for a target temperature. The number is to remind you which segment will use this target temperature. ELEC Electronics The Sentry circuit board is rated for operation at temperatures up to 158°F/70°C. When the circuit gets hotter, the Sentry shuts off. The ELEC option tells you how hot the circuit board is. ETH Electronics Too Hot The Sentry circuit board is too hot, so the kiln was shut off. FAIL Failed The thermocouple failed. This can be due to a broken thermocouple, loose thermocouple connection on the back of the Sentry, disconnected thermocouple wire, or a defective controller. FTH Failed to Heat The kiln cannot heat as fast as you programmed or is not heating at all. C perhourand the firing .F/15.FTL Firing Too Long Thetemperature rise is less that27 time is four hours longer than the current segment was programmed. FULL Full Speed The rate, or temperature change per hour, is maximum. Hd 1 Temperature Hold When this message appears during Ramp-Hold programming, it is asking you if you want to hold, or maintain, the target temperature of that segment. If so, enter the length of hold time in hours and minutes (i.e. 1 hour 20 minutes = 01.20). The number after Hd is the segment number. Each segment in a Ramp-Hold firing is numbered starting with 1.
