Wiring the Display Head
Figure 19. Emergency Stop Switch Mounting And Wiring Diagram
Wiring the Display Head
1.
With the Display Head cover still off, remove the nut and bushing from the top side panel cord grip connector.
Note: the maximum cable length between the Interconnect Box and the Display Head is 1000 feet (304.8
meters).
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 20. Slide the tapered end of the bushing into the cord grip, then screw on the cord
grip nut and tighten securely.
3.
Attach the four-wire IB cable to the terminal block where shown in Figure 20. Attach the drain wire of the IB
cable to a grounding lug on the Pulse Encoder mounting base.
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. 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 20. Slide the bushing into the cord grip and then screw the cord grip nut
onto the cord grip and tighten securely. Attach the shield of the temperature probe cable and/or ESS switch
cable to a grounding lug on the pulse encoder mounting base.
