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. Try to keep power terminal L 1 and L2 in approximately
the same location as before to help prevent the need for longer wire lengths.
3. Mount the DIN Rail (D03-0013-BRK) next to the KBIC board if possible using a 9/64" drill bit. Use
the self tapping screws to secure the DIN Rail to the panel. Snap the SCR contactor (D03-0106)
onto the DIN Rail.
4. Reconnect the wires as follows:
Previous Woods Terminal New KBIC Terminal Previous Woods T erminal New KBIC Terminal
L1 T1 of SCR Contactor 1 P1
L2 T3 of SCR Contactor 2 P2
F1 F+ 3 P3
F2 F- 6 N.C. See text in Step 8
A1 A+ 7 N.C. See text in Step 7
A2 A
5. Strip the end of the supplied black 16 gauge wire and connect it to the wire between the L1 terminal
of the SCR contactor and the L1 terminal of the KBIC board. Now strip and connect a wire to the
L3 terminal of the SCR contactor and the L2 terminal of the KBIC board.
6. Connect the supplied white 18 gauge wire to the A2 terminal of the SCR contactor. Connect the
other end to any available AC neutral connection. This is usually a white wire labeled with a
number 2 at its connection point.
7. Connect the wire (See Figure 2A on Page 7) that was connected to terminal 7 on the Woods board
to the A1 terminal of the SCR contactor. If additional wire length is required, use part of the supplied
yellow 18 gauge wire and wire nut (HH-1462).
8. Connect the wire that was connected to terminal 6 to the supplied yellow 18 gauge wire using the
supplied wire nut (HH-1462) and the other end to a fused 110 VAC power sou rce. You can use any
connection that wire number 3 or number 27 is connected to.

2. Installation
Figure 2A Wiring Diagram for all FFI Dryers
The board is ready to be calibrated unless the drye r 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. If this wire was
not present on your Woods board, please remove the wire with wire cutters.

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.)
Minimum Potentiometer Adjustment
Set the SCR Speed Control knob on the ASC panel at the 10% setting. Adjust the minimum potentiometer
to obtain 15.5 VDC across the DC motor armature terminal A+ and A-.
Recheck the maximum potentiometer setting and readjust if necessary. Repeat and readjust the
minimum potentiometer if necessary. Rechecking the maximum and minimum potentiometer settings
once should be sufficient.
