9.4 Replacing PWA

About the PWA

Electronics Board The circuitry in the ST 3000 Release 300 transmitters is of the single

PWA design. The PWA contains connectors for the flex-tape conductor

from the sensor, the loop power wires and a connector for the optional

smart meter cable.

Procedure The procedure in Table 55 outlines the steps for replacing the PWA.

Table 55 Replacing PWA.

Step Action

1

Turn OFF transmitter power.

ATTENTION We recommend that you remove the transmitter

from service and move it to a clean area before taking it apart.

2

Loosen end cap lock and unscrew end cap from electronics side of

transmitter housing.

We recommend that you use a ground strap or ionizer when handling

the PWA, since electrostatic discharges can damage certain circuit

components.

3

• If equipped with a Local Smart Meter, carefully turn Smart Meter

counterclockwise to remove it from PWA mounting bracket and

unplug cable from connector on back of meter assembly.

• Loosen two retaining screws and carefully pull mounting bracket

and PWA from housing.

• Using the retaining clip, unplug flex tape connector and 2-wire

power connector from PWA, and remove PWA.
