5.6.7 Changing the housing orientation
The entire electronics housing may be rotated in 90 degree increments for easy viewing. Use the
following steps to change the housing orientation:
1. Loosen the screw on the access cover on the bracket (if present) and remove the cover.
2. Loosen the three housing rotation set screws at the base of the electronics housing with
a
5
/32-in. (4 mm) hex wrench by turning the screws clockwise (inward) until they clear
the bracket.
3. Slowly pull the electronics housing out of the bracket.
4. Unscrew the sensor cable from the housing with a
5
/16-in. open end wrench.
Note
Do not pull the housing more than 1.5-in. (40 mm) from the top of the bracket until the sensor
cable is disconnected. Damage to the sensor may occur if this sensor cable is stressed.
5. Rotate the housing to the desired orientation.
6. Hold it in this orientation while you screw the sensor cable onto the base of the
housing.
Note
Do not rotate the housing while the sensor cable is attached to the base of the housing. This will
stress the cable and may damage the sensor.
7. Place the electronics housing into the top of the bracket.
8. Use a hex wrench to turn the four housing rotation screws counterclockwise to engage
the bracket.
5.6.8 Temperature sensor replacement
(MTA option only)
Replacement of the temperature sensor should only be necessary in the event of a failure. Use
the following procedure for replacement.
Note
Disconnect power before replacing temperature sensor.
1. Turn off power to Rosemount 8600D.
2. Remove temperature sensor from meter body by using a
1
/2-in. open end wrench. Refer
to the procedure on page 81 to remove the bracket.
