6. Tighten the four screws with the 5 mm hex key.
7. After installing the new display power up the unit (refer to “Power Up the SVI FF” on
page 78).
Make sure that:
The gasket is seated in the groove in the housing flange.
No wires or retaining cable can be trapped under the cover flange.
The flange area is not corroded and the surface is not scarred.
The four cover bolts are securely tightened to 50 in-lbs (5.65 N-m).
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 FF Display Cover” on page 84) 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.
The cover of the SVI FF is a critical component for safety in
Hazardous Areas. To ensure safe operation the flat surfaces of the
cover and the housing must be clean and absolutely free of
particles or dents. There must be no gap between the housing and
cover; torque spec is 50 in-lbs (5.65 N-m).
