Wiring the Display Head
1. With the Display Head cover still off, remove the nut and bushing from the right-side panel cord grip
connector.
2. Slide the cord grip nut and then the bushing over the IB cable leads. Pull enough cable through so that the
leads reach the terminal block on the Display Assembly and can be tie wrapped to the Pulse Encoder
mounting base as shown in Figure 18. Slide the tapered end of the bushing into the cord grip, then screw on
the cord grip nut and tighten securely.
3. Attach the IB cable to the Terminal Block as shown in Figure 18. Attach the drain wire of the IB cable to a
grounding lug on the Pulse Encoder mounting base as shown in Figure 18.
When stripping wire for terminal block connections, be careful not to nick the individual strands. Also, be sure
to tighten each terminal so the wire can not be pulled out. A failure to follow either of these instructions can re-
sult in signal loss and faulty operation.
4. If you have the optional temperature probe and/or ESS switch, remove the lower cord grip nut and slide it,
then the tapered bushing, over the temperature probe and/or ESS switch cable(s). Pull enough cable through
so that the leads reach the terminal block on the Display Assembly and can be tie wrapped to the Pulse
