COOLING FAN TEST (2nd Test)
1. To enter Cooling Fan Test, touch the "+" keypad of the 3000W inductor. The bar lights will show 2 LEDs and fl ash at
the rate of .75 seconds ON and .25 seconds OFF.
2. The 1200W inductor will have all the bar lights illuminate.
3. The cooling fan relay will turn ON causing the fan to turn ON.
4. When the "-" keypad of the 1200W inductor is touched, all bar lights of the 1200W inductor control and cooling fan will
turn OFF.
5. When the "+" keypad of the 1200W inductor is touched, all bar lights of the 1200W control will illuminate and the fan
will turn ON.
6. A press of the "-" key on the 3000W inductor will step the user back one test to the LED Test.
CONTROL TEMPERATURE TEST (Third Test)
1. To enter Control Temperature Test, touch the "+" keypad of the 3000W inductor controls.
2. The 3000W bar lights will show 4 LEDs and fl ash at a rate of .75 seconds ON and .25 seconds OFF..
3. The 3-digit display illuminates Ambient Control Temperature in °F.
4. A press of the "-" key on the 3000W inductor will step the user back one test to the Cooling Fan Test.
HEAT SINK THERMISTOR TEMPERATURE TEST (Forth Test)
1. To enter Heat Sink Thermistor Temperature Test, touch the "+" keypad of the 3000W element controls.
2. The 3000W bar lights will show 5 LEDs and fl ash at a rate of .75 seconds ON and .25 seconds OFF.
3. The 3-digit display illuminates Heat Sink THERMISTOR temperature in °F.
4. The 1200W control will display LEDs 1, 2 and 3 to indicate each of the heatsink temperatures (36" has 3, 30" has 2
and 15" has 1)
5. To access each of the heatsink temperatures, the user will touch the "+" and "-" keys of the 1200W control.
1 LED = Generator Board #1: Center board for 15"; Right side of 30" or middle two coils of 36" units
2 LEDs = Generator Board #2: Left board 30" & 36" units
3 LEDs = Generator Board #3: Right board 36" units
6. A press of the "-" key on the 3000W element will step the user back one test to the Control Temperature Test.
ERROR CODE INDICATOR (Fifth Test)
NOTE: See Error Code Chart at the end of this section for a description of the error and action that should be taken.
NOTE: IF ONE POSSIBLE CAUSE OF AN ERROR CODE HAS BEEN CORRECTED, RESET ERROR HISTORY AND
VERIFY OPERATION. ONLY PROCEED TO OTHER POSSIBLE SOURCES IF THE PROBLEM STILL EXISTS OR IF
THE ERROR REOCCURS.
NOTE: Error code history can be cleared by touching and holding the "OFF ON" keypad of the 1200W element controls
for 5 seconds.
NOTE: Error codes should be cleared after service is complete.
1. To enter Error Code Indicator, touch the "+" keypad of the 3000W element controls.
2. The 3000W bar lights will show 6 LEDs and fl ash at a rate of .75 seconds ON and .25 seconds OFF.
3. The 1200W element controls will illuminate 0-16 bars based on which error code is being displayed in 3 digit timer
display. If no errors were recorded, zero bar lights will illuminate and the 3 digit timer display will be blank.
4. The 3-digit display will show the corresponding error code stored in memory, and will be displayed as Exx.
5. Pressing the "+" key of the 1200W control will cause the digits of the Error Code Time Stamp to be displayed (See
Figure 5-3)
