Troubleshooting
Reinstalling the core processor
If you removed the core processor, replace the core processor according to the instructions below.
1. If you have a standard core processor:
a. Align the three guide pins on the bottom of the core processor with the corresponding
holes in the base of the core processor housing.
b. Carefully mount the core processor on the pins, taking care not to bend any pins.
2. If you have an enhanced core processor:
a. Plug the sensor cable onto the feedthrough pins, being careful not to bend or damage any
pins.
b. Replace the core processor in the housing.
3. Tighten the captive screw(s) to 6 to 8 in-lbs (0,7 to 0,9 N-m) of torque.
4. If you have a 4-wire remote installation, replace the core processor lid.
5. 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).
Note: When reassembling the flowmeter components, grease all O-rings.
