Installing the PE
Assembly
Follow the steps below to install the programming electronics assembly
in the 2500.
1. Turn off the 2500 and remove the power cord.
CAUTION: Pins in the pin block are delicate and could be damaged if
they hit components mounted on the underside of the main
plate. The pin block cover ensures that these pins are not
damaged while you are removing or reinstalling the PE
assembly.
2. Carefully slide the PE assembly onto the clamp assembly. Figure 7-7
shows the two tracks on the clamp assembly that fit into grooves on
the pin block.
3. Install the retaining bar and its two hex screws to connect the PE
assembly to the clamp assembly.
4. Reconnect the two optic cables (S-24 and C-25).
5. Reconnect the two of the four air lines (one red and one blue) to the
rear quick connects.
6. Hold the programming module clamp assembly in place and reinstall
the six 7/64-inch hex screws.
7. Reconnect the two remaining air lines (one red and one blue) to the
front quick connects.
8. Reconnect all of the remaining cables.
CAUTION: When you connect the cables, be careful to use the correct
polarity of the cables to the connectors. Reversing or
misaligning a cable could damage components on the 2500.
9. Connect the 2500 to a compressed air source and check for air leaks
by listening for a hissing sound.
10. When you determine that there aren’t any air leaks, lower the main
plate.
11. Tighten the two corner screws in the main plate (see Figure 7-3).
