the result will be:
• The bar lights on the 1200W control will illuminate 5 LEDs
and flash at the rate mentioned in Mode1.
• The bar lights on the 2200W control will illuminate a number of LEDs based on the temperature of the heat
sink thermistor on the power board using four Hex Decimal Characters and flash at the rate described in
Mode 1.
(See Figure 5-2).
Mode 6 - Checking the Lid Switch on the Cover - (Not Used)
To enter Mode 6 while engaged in diagnostic mode, touch the “+” keypad on the 1200W control. When this is done
the result will be:
• The bar lights on the 1200W control will illuminate 6 LEDs
and flash at the rate mentioned in Mode1.
• The bar lights on the 2200W control will illuminate 4 LEDs in hex decimal form, based on the Lid Switch
status (open or closed) and flash at the rate mentioned in Mode1.
NOTE: If the numbers are between 580 to 748, the Lid switch is open.
NOTE: If the numbers are between 239 to 443, the Lid Switch is closed.
NOTE: Any other numbers other than 580 to 748 and 239 to 443, mean error.
(See Figure 5-3).
Mode 7 - Last Error Code Recorded to Eeprom
To enter Mode 7 while engaged in diagnostic mode, touch the “+” keypad on the 1200W control. When this is done
the result will be:
• The bar lights on the 1200W control will illuminate 6 LEDs
and flash at the rate mentioned in Mode1.
• The bar lights on the 2200W control will illuminate 0-9 LEDs based on the last error code recorded to the
Eeprom, and flash at the rate mentioned in Mode1. If error codes were recorded, bar lights 1-6 will
correspond to one of six possible error codes.
NOTE: If no
error codes were recorded, zero bar lights will illuminate.
Mode 8-14 - Preceding Error Codes Recorded to Eeprom
To enter the corresponding Mode (8-14), touch the “+” keypad on the 1200W control. When this is done the result
will be:
• The bar lights on the 1200W control will illuminate the number of LEDs according to the corresponding
mode (8-14).
• The bar lights on the 2200W control will illuminate 0-9 LEDs
based on the next to last error code recorded
to the Eeprom and flash at the rate mentioned in Mode1. Each additional Mode will indicate the preceding
error code recorded to the Eeprom. If error codes were recorded, bar lights 1-6 will correspond to one of six
possible error codes.
NOTE: If no
error codes were recorded, zero bar lights will illuminate.
NOTE: There can be a total of eight
error codes recorded.
Mode 15 - Checking Software Version -
To enter Mode 15 while engaged in diagnostic mode, touch the “+” keypad of the 1200W control. When this is
done the result will be:
• The bar lights on the 1200W control will illuminate 15 LEDs
and flash at the rate described in Mode1.
• The bar lights on the 2200W control will illuminate four groups of four LEDs in Hex Decimal form based on
the software version present in the unit and flash at the rate mentioned in Mode1.
