5.5 Secure cover jam screw
For transmitter housings shipped with a cover jam screw, the screw should be
properly installed once the transmitter has been wired and powered up. The
cover jam screw is intended to disallow the removal of the transmitter cover in
flameproof environments without the use of tooling.
Procedure
1. Verify the cover jam screw is completely threaded into the housing.
2. Install the transmitter housing cover and verify that the cover is tight
against the housing.
3. Using an M4 hex wrench, loosen the jam screw until it contacts the
transmitter cover.
4. Turn the jam screw an additional ½ turn counterclockwise to secure
the cover.
CAUTION
Application of excessive torque may strip the threads.
5. Verify that the cover cannot be removed.
