Procedure 5-3 Connecting the TB Holder to the I/O Module
1) Open the door of the I/O module.
2) On the TB holder, loosen the screw and turn the positioner so that the arrow points to
either A or B.
3) Tighten the screw.
4) With a flat screwdriver, set the code key pin to a number from 1 to 6.
5) On the I/O module, using a flat screwdriver, set the pin to the same number (from 1 to 6.)
This ensures that the TB holder will not be accidentally connected to the wrong I/O
module.
6) Slide the plastic lip on the bottom of the I/O module to either A (up) or B (down) (as in
Step 2).
7) Align the plastic lip with the flat edge of positioner on the TB holder and snap the TB
holder into the I/O module, (see Figure 5-8), fitting the code key pin into the code key.
8) If the ejector handles are extended, push them inwards, against the TB holder (see Figure
5-8.)
9) If a TB holder clip was attached to the I/O module, slide the cable between the two edges
of the clip, and press the clip closed to secure the TB holder to the module. See Figure 5-7.
