  • Page 21: Ohm Testing Elements At Relay Board

    Ohm Testing Elements at Relay Board This procedure will allow the service technician to ohm any of the ele- ments directly at the relay board. At the relay board, pull the wire off of the terminal DLB/E11. This is done to keep from ohming the relay board. It does not take the High Limit out of the equation, but if the technician DOES NOT get an ohm reading from the DLB lead to all of the element leads, then, there is a problem with the High Limit.

  • Page 48 INTERPRETING HEX DECIMAL CODE The bar lights located on the control panel are divided into four differ- ent groups. These four groups have numeric values. (See Figure 1). When the bar lights are illuminated, the numeric value for each group needs to be added together.
  • Page 49 In Figure 2, you see an example of bar lights that could be illuminat- ed. When reading the bar lights according to Most Significant to Least Significant numeric value, they add up to: 2 + 1 = 3; 4 + 1 = 5 and 8 + 4 = 12 or C. So you have 3 - 5 - C.
