Junction box to 9-wire transmitter
If connecting from a D600 sensor with an integral booster amplifier and
junction box (see Figure 1) or from a remote booster amplifier with a
junction box (see the left side of Figure 4), follow the steps below to
connect the 9-wire cable between the junction box and the transmitter.
1. Prepare and install the cable according to the instructions in Micro
Motion’s 9-Wire Flowmeter Cable Preparation and Installation
Guide.
2. Insert the stripped ends of the individual wires into the terminal
blocks. No bare wires should remain exposed.
3. Match the wires color for color. For wiring at the transmitter, see the
transmitter Quick Reference Guide.
4. Tighten the screws to hold the wires in place.
5. Ensure integrity of gaskets, grease all O-rings, then tightly close and
seal the junction box cover and all housing covers on the transmitter.
CAUTION
Failure to seal sensor and transmitter housings could
cause a short circuit, which would result in
measurement error or flowmeter failure.
• Ensure integrity of gaskets and O-rings.
• Grease all O-rings before sealing.
• If conduit is used, install drip legs in conduit.
• Seal all conduit openings.
CAUTION
Allowing the shield drain wires to contact the sensor
junction box can cause flowmeter errors.
Do not allow the shield drain wires to contact the sensor
junction box.
