I ⁄ P Module Removal and Installation
Prior to removing the pneumatic components it is necessary to remove the electronics
module cover (see “Removing the SVI II AP Display Cover” on page 139) and the pneumatic
cover first.
Do not remove the I/P module in a hazardous area unless the power is disconnected.
Application of more than 1.6 mA to the I/P motor can permanently damage it.
The I/P is rigidly assembled to a wire way sleeve that is a critical component for explosion
proof service. Use care to slide the sleeve from the pneumatic module without applying a
strain to it.
Pneumatic Cover Removal: AP and High Flow
To remove the AP pneumatic cover:
1. Using a 3 mm hex key, remove the six screws from around the perimeter of the cover.
2. Lift the cover off and put aside for re-installation.
To remove the AP High Flow pneumatic cover:
1. Using a 3 mm hex key, remove the four screws from around the perimeter of the cover
(Figure 59 or Figure 60).
