In an effort to continuously adapt our product based on feedback from our customers, we made a small change regarding the wiring of our pressure transducers. Previously, transducers were wired directly into the Variable Frequency Drive’s (VFD) internal terminal blocks. Now, Franklin Control Systems will provide terminal blocks mounted on the back panel of all NEMA 1 and NEMA 3R centrifugal and submersible VFD packages for easier transducer installation. This will allow customers to wire transducers without removing the VFD cover.

Transducer wiring procedure is provided below:

Peel back insulation to expose shield (bare) wire. Note: Green and white wires should not be used.

 

PREVIOUS TERMINAL BLOCK LOCATION (Inside VFD):

 

EXTERNAL TERMINAL BLOCKS:

 

LOCATION OF EXTERNAL TERMINAL BLOCKS:

This should provide an easier installation for all our customers. If you have any further questions, please contact your local Territory Manager, Field Service Engineer or our Hotline at 800-348-2420.
