installation. In an Explosion-proof/Flame-proof installation, do not remove the transmitter
covers when power is applied to the unit.

Process leaks may cause harm or result in death

• Install and tighten thermowells or sensors before applying pressure.

• Do not remove the thermowell while in operation.

Electrical shock can result in death or serious injury

• Avoid contact with the leads and terminals. High voltage that may be present on leads
can cause electrical shock.

STEP 1: DISASSEMBLING THE TUBE AND TRANSMITTER

1. Shut off the power going to the magnetic transmitter.

2. Remove the cover on the terminal strip side of the electronics housing.

3. Disconnect all wires from the terminal block. This will require a Phillips screwdriver.

4. Remove the conduit and wiring from the transmitter housing.

5. Replace the terminal strip side cover.

6. Open the LOI/Electronics cover.

7. Disconnect the quick connect connectors from the circuit board sockets. See Figure 4.
(For units equipped with a LOI, it will be necessary to remove the LOI to access the
connectors. This will require a small standard screwdriver.)

8. Remove the 4 bolts from the mounting plate on the flow tube holding the transmitter in
place. This will require the 10 mm wrench. See Figure 1.

9. Carefully lift the transmitter off of the mounting plate.

10.Disconnect the transmitter wiring from the terminal block on the flow tube. This will
require a small standard screwdriver. This wiring harness is no longer needed.

conversion kit.

3. Place the remote mount junction box on the flowtube mounting plate.

4. Mount the junction box with the 4 bolts provided in the kit. See Figure 2.

STEP 3: PREPARING THE TRANSMITTER

1. Position the remote mount terminal box adjacent to the transmitter and carefully feed the
wire leads so that they are accessible from the electronics access of the transmitter.

2. Place the O-Ring in the groove on the remote mount terminal box.

3. Mount the remote mount terminal box to the transmitter using the bolts provided.
See Figure 3.

4. Connect the wires from the remote mount terminal box to the electronics. Note that the
sockets are different sizes so that they can only be connected one way. See Figure 4.

5. Replace the LOI (if applicable).

6. Replace the electronics side cover.

wiring terminations between the Transmitter Remote Terminal box and the Flowtube
Terminal Junction Box.

2. Install all conduit and wiring in accordance with all local and plant electrical codes.

3. When the wiring between the flowtube and transmitter are complete, replace the covers
to both the flowtube junction box and the remote mount terminal box on the transmitter.
