Adding an AC Relay Board to the Xi
1. Loosen the four screws securing the Xi cover. The screws are captive
and do not need to be completely removed.
2. Swing the Xi cover down to expose the inner components.
3. Slide the I/O Board part way out of the Xi enclosure.
4. Make the following jumper and switch settings:
a. Set SW4, Position 4 "ON" and all other positions "OFF".
b. Move the jumpers for both JP1 and JP2 to pins 1 and 2.
5. The I/O Board must be relocated to the right-most slot inside the Xi
enclosure. If there is enough service loop on the existing wiring, slide
the I/O Board completely out of the enclosure and re-install it in the
right-most slot. Ensure the board is correctly aligned within the slots.
See Figure 6-8 for the correct location of the I/O Board.
NOTES
An AC Relay Board can only be added to single channel Xi, i.e. only one I/O
Board controlling one O
2
Probe.
The Flame Status Interlock function requires a contact closure on the digital
input of the I/O Board to indicate a flame is present. When properly connected
and configured, AC power will be applied to the transmitter only when the
flame is present.
6. If there is not sufficient wiring, tag and disconnect all wiring, and
relocate the board. Then reinstall the wiring.
7. Partially slide the AC Relay Board into the left-most slot of the Xi
enclosure. The component side of the AC Relay board will be to the
right with the fuse holder at the top. Ensure the board is correctly
aligned within the slots in the enclosure. See Figure 6-8 for the correct
location of the AC Relay Board.
Installing and configuring an AC Relay Board for the Flame Status Interlock function will
dedicate alarm output 2 for this function. Once configured for Flame Status Interlock, the
software will override any previous alarm assignments for alarm output 2 and not allow it to
be used for any other function.
