6. Measure the resistance between core processor terminals 3 and 4 (RS-485A and RS-485B).
See Figure 10-1. Resistance should be 40 kΩ to 50 kΩ.
7. Measure the resistance between core processor terminals 2 and 3 (VDC– and RS-485A).
Resistance should be 20 kΩ to 25 kΩ.
8. Measure the resistance between core processor terminals 2 and 4 (VDC– and RS-485B).
Resistance should be 20 kΩ to 25 kΩ.
9. If any resistance measurements are lower than specified, the core processor may not be able to
communicate with a transmitter or a remote host. Contact Micro Motion (see Section 10.3).
To return to normal operation:
1. Reconnect the 4-wire cable between the core processor and the transmitter (for Model
1500/2500 transmitters, see Figure B-3; for Model 1700/2700 transmitters, see Figure B-12).
2. If you have a 4-wire remote installation or a remote core processor with remote transmitter
installation, replace the core processor lid.
3. If you have an integral installation:
a. Gently lower the transmitter onto the base, inserting the cap screws into the slots. Do not
pinch or stress the wires.
b. Rotate the transmitter clockwise so that the cap screws are in the locked position.
c. Tighten the cap screws, torquing to 20 to 30 in-lbs (2,3 to 3,4 N-m).
4. If you have a 9-wire remote installation:
a. Gently slide the mounting plate into place. Do not pinch or stress the wires.
b. Rotate the mounting plate so that the screws are in the locked position.
c. Tighten the screws, torquing to 6 to 8 in-lbs (0,7 to 0,9 N-m).
d. Replace the end-cap.
Note: When reassembling the flowmeter components, be sure to grease all O-rings.
