9.4Replacing Electronics Module or PROM

Module description

The electronics module used in the SMV 3000 transmitter is a two Printed Wiring Assembly design that includes an integral mounting bracket, we refer to the PWAs as Main PWA and Temperature or Daughter PWA as a way to distinguish them.

PROM identification

 

The plug-in PROM on the main PWA is uniquely characterized to the

 

 

meter body of the given transmitter. For this reason, each PROM is given

 

 

a 10-digit identification number so you can verify that a replacement

 

 

PROM is the correct match for the given transmitter. The PROM

 

 

identification number is stamped on the nameplate on the transmitter’s

 

 

meter body and appears on a label under the PROM. You can also read the

 

 

PROM number using the SCT – See Section 8.2 in this manual for details.

Procedure

 

 

 

The procedure in Table 28 outlines the steps for replacing the electronics

 

 

module or the plug-in PROM. Since you must remove the electronics

 

 

module and PROM in either case, you can easily adapt the steps as

 

 

required.
