2. Installation Replacing the Woods Board 1. Disconnect the power to the circuit. 2. For ease of re-connection, record the colors and terminal numbers of all wires leading to the Woods board. Disconnect wiring and remove board. Mount the KBIC board in approximately the same location, oriented as shown in Figure 1A on Page 5. Note that additional holes must be drilled into the mounting surface using a 9/64" drill bit.
2. Installation Figure 2A Wiring Diagram for all FFI Dryers The board is ready to be calibrated unless the dryer is equipped with a Vari-Trol “VM” (Honeywell digital type control), in which case the following additional step is required before calibration. • If the dryer has a Honeywell Vari-Trol control and an Auto-Range module, connect the red wire (#54) attached to the KBIC board to the terminal 1 of the Auto-Range module base.
3. Adjusting SCR Motor Speed Maximum Potentiometer Adjustment With dryer unload circuit energized, set the SCR Speed Control knob on the ASC panel to 100%. Using a small blade screwdriver, adjust the maximum potentiometer to obtain 155 VDC across the DC motor armature terminals A+ and A- on the KBIC board. (NOTE: Some early M-Series dryers were designed to operate with a 175 VDC armature voltage. Consult the factory if there is any question regarding these early models.
