• After completing connections locate retaining clips in the appropri-

ate notches and carefully place into the housing. Be sure that inter-

nal sensor transmission wire does not cross the power supply lines

just installed.

• If using the Cable Gland be sure to properly tighten sealing grommet

before applying any tension on the cable, the cable gland provides

strain relief and environmental sealing.

• Tighten GC52 cover to maintain environmental rating.

• Connect to power source and receiver and power on to confirm cor-

rect wiring (see Section 10 for more detail).

• Power Supply Requirements: Although the 4-20mA signal can travel

over long distances one of the most common problems is inadequate

power at the pressure transmitter due to the voltage drop across the

loop. Be sure to review table below to determine that 12-32V is get-

ting to the pressure transmitter.
