2. Remove the standoff and the screw that secures the
EMI filter board to its standoff. Then, pull the board from
its socket to access the TB3 connector, and loosen the
terminal screws on the TB3 connector.
3. Connect the power leads:
CAUTION!
Connecting the +24 VDC line (red) lead to any
terminal except TB3-1 will damage the XMO2.
a. Insert the 4-wire cable +24 VDC line (red) lead into
pin TB3-1 and tighten the screw.
b. Insert the 4-wire cable 24 VDC return (black) lead
into pin TB3-2 and tighten the screw.
4. Connect the analog output leads:
a. Insert the 4-wire cable + 4-20 mA (white) lead into
pin TB3-3 and tighten the screw.
b. Insert the 4-wire cable - 4-20 mA (green) lead into
pin TB3-4 and tighten the screw.
5. Plug the EMI board back into its socket and secure it with
the standoff. Terminate the ground lug of the cable to
the standoff and secure it with the provided screw.
6. If you are installing the second cable entry device, do so
in accordance with the manufacturer’s instructions.
Note: If installation of the cable entry device is only partially
complete, Panametrics recommends tagging the device to
ensure the safety of subsequent users.
a. Remove the tab “Remove Before Installation”.
b. Thread the cable gland entry body into the
remaining XMO2 port.
c. Route the 3-wire RS232 cable and its ground lug
through the cable gland.
d. Fray the braided shield and spread evenly around
the cone as shown in Figure 90 on page 71.
Compress the ring to lock the shield.
e. After terminating the shield as shown, assemble
the gland pieces together and tighten the gland to
secure the cable and the shield.
IMPORTANT:
The cable shield must be terminated in the cable gland as
shown in Figure 90 on page 71.
7. Unplug the TB2 connector by pulling it straight out
of its socket, and loosen the terminal screws on the
TB2connector.
8. Connect the RS232 serial port leads:
a. Insert the 3-wire cable RX (red) lead into pin TB2-1
and tighten the screw.
b. Insert the 3-wire cable TX (white) lead into pin TB2-2
and tighten the screw.
c. Insert the 3-wire cable GND (green) lead into pin
TB2-3 and tighten the screw.
9. Carefully plug the TB2 connector back into its sockets.
Terminate the ground lug to the nearest standoff.
10. Reinstall the cover on the XMO2.
11. Connect the other ends of the cables to the 24 VDC
power supply, the 4-20 mA input of the display device,
and the serial port of the computer or terminal (see the
instruction manuals for those devices for details).
