With the DMM set to its highest range, there should be infinite resistance on each lead. If there
is any resistance at all, there is a short to case or a short between pins. See Table 10-8 for
possible causes and solutions. If the problem is not resolved, contact Micro Motion.
To return to normal operation:
1. Reach inside the transmitter housing and install the transmitter’s sensor connection onto the
feedthrough:
a. Rotate the connector until it engages the pins.
b. Push down until the wings engage and the red color is no longer visible.
2. Replace the transmitter in the transmitter housing, and tighten the screws.
3. Reconnect the I/O wires.
4. Reconnect the power wires, lower the Warning flap, and tighten the Warning flap screw.
5. Plug the user interface module onto the transmitter. There are four possible positions; select
the position that is most convenient.
6. Tighten the user interface screws.
7. Replace the user interface cover on the user interface module, and tighten the screws.
