DEAD UNIT: Turn off circuit breaker, wait 30 seconds, and turn circuit breaker on. Proceed to tests below.
DISPLAY CHECK: Turn burner on Level 8. All segments should light. Set 4 burners to 1, 2, 5, and 8. Check for
proper digit displays. When power is fi rst applied, all the segments light in a sequence. Check for a consistent
pattern, none missing or doubled up.
VERSION DISPLAY: When the power is fi rst applied, after the display test sequence, the 4-digit version
number of the touch board is momentarily shown in the display.
TOUCH KEYS IN GENERAL: Keys should respond to a grounded surface on the glass of 0.350-inch diameter,
which is the model for a fi nger. Keys should not respond to a grounded surface less than 0.130-inch
diameter. Water, etc., on the keys may cause them to not respond correctly because of unwanted ground
coupling. However, the OFF function will respond regardless of contamination. If the contamination is severe
enough to completely prevent touch key response, supervisory functions will turn off the burner. Removing
the contamination should restore proper key operation. After cleaning the keypad glass (ensure the keypad
is clean and dry), wait 30 - 60 seconds for keypad sensitivity to stabilize. A gap or moisture between the
touch board and glass will affect touch key performance. If this occurs, the glass assembly should be
replaced.
