INSTALLATION

4.4.4 Local Digital Meter Installation, Repositioning and Removal

Three procedures are provided in this section. Refer to Figures 4-9 and 4-10 as necessary.

IMPORTANT

Follow proper electronic circuit board handling procedures to avoid damage to the semiconductors by electrostatic discharge.

Two procedures describe repositioning of an installed meter: A is for rotating the meter 180°, and B is for rotating the meter 90° clockwise or counterclockwise (actually ±78°).

To remove a meter, perform procedure A, steps 1-5 and 9.

To install a meter perform procedure C.

A.Rotate Meter 180°

1.Turn off power to transmitter and remove enclosure cap to access Digital Display.

2.Snap wrist strap on wrist and connect ground clip to an unpainted area on the Transmitter or mounting bracket.

3.Locate a short ribbon cable that connects the Electronics Module to the Digital Meter assembly, at connector J1 typically. Disconnect the connector at the Digital Meter assembly and the slide cable from cable slot.

4.Loosen (do not remove) upper right and lower left assembly retaining screws.

5.Gently rotate assembly counterclockwise to position upper right retaining screw in large hole in keyhole and carefully lift assembly clear of screw, then slide it clear of lower left retaining screw.

6.Rotate the assembly 180°, place under the retaining screws, rotate assembly clockwise, and tighten screws.

7.Position ribbon cable in closest cable slot and connect cable to connector J3.

8.Disconnect wrist strap's ground clip.

9.Replace enclosure cap and restore power to transmitter.

B.Rotate Meter 90° CW or CCW

1.Remove Digital Meter assembly as described in paragraph A, steps 1 to 5, above.

2.Remove the upper right 3.25-inch hex stand-off. Install the stand-off in the upper left mounting hole.
