Appendix F: Replacing A Module
This appendix provides instructions on replacing a module on the rear panel of the PRO X Control Centre.
Replacing a module
The design of the PRO X Control Centre makes I/O module replacement very easy and straightforward. The I/O modules are situated at the rightmost side of the
rear panel of the PRO X Control Centre, as shown below.

There are three module positions and any of the modules mentioned in Chapter E “I/O Modules” can be tted. Each position has rack guides so that the modules can
slide easily in and out. Each module is securing with two screws.
>> To remove a module
1. Switch o and electrically isolate the PRO X Control Centre, as detailed in “Powering the system” in chapter 4.
2. Remove the two securing screws from the left and right sides of the module you want to remove, as shown in the diagram below.

3. Using both hands, take hold of the circular machined posts and ease the module out of the slot.
>> To t a module
1. Make sure the PRO X Control Centre is switched o and electrically isolated; see “Powering the system” in chapter 4.
2. Oer up the rear of the module to the aperture in the module slot.
3. Carefully ease the module into the slot and then push it all the way in until it reaches its tted position.
Caution:
Be careful not damage the inside of the slot or the module itself by using too much force when pushing the module into the slot.
If you feel some resistance, remove the module and try again.
4. Switch on the PRO X Control Centre (see “To switch on the control centre” in chapter 4) and check that the module is functioning correctly.
The PRO X Control Centre recognises the type and position of every module in its I/O rack. However, after tting a new module, you may need to congure some of its
options; see Chapter 27 “Changing The User Settings”.
