2.13 Mounting the Display Pendant
The ProtoTRAK SMX display pendant mounts to the pendant arm with four 1/4-20 x ¾ SHCS that are shipped screwed
into the left side of the display. There is a locating screw on the pendant arm to help align the pendant with the
mounting holes.
CAUTION!
The locating screw in the arm is used for positioning. Keep a hold of the pendant
until the screws are fastened.
If the pendant arm rotates too freely, remove the painted cap on the bracket attached to the column and tighten the
hex nut to adjust it. Replace the cap.
2.14 Cable Interconnections
All cable interconnections are made at the factory except for those connecting to the pendant display. There are a total
of 4 cables that need to be connected to the pendant for non-spindle control machines. See Figure 15 & 16 for a
complete illustration of cable interconnections for all components. There are an additional 2 cables for the electronic
handwheel option and 2 more cables for the spindle control option (digital I/O and spindle control ports).
With the main power to the machine turned off, plug in the connectors that are bundled on the pendant arm. Each
cable mates to only one connector on the pendant display back panel. Use the key on the pendant to match up the
connectors with the correct port. The machine ID port (or called LPT) and parallel port (hardware key) will have a key
plugged into it. The monitor port and network ports will be left empty during installation.
Make sure there is sufficient slack in the cables for when the pendant is rotated about the pendant arm. The worst case
is when the pendant is all the way forward toward the operator. The following drawing describes all of the cable
connections to the pendant.
Make sure there is a hardware (option) key plugged into the parallel port of the pendant. This key activates any
converters or options ordered. The part # for this key is 22648. The key must be programmed according to the type of
machine it is on and the options ordered.
