3.6 Output Wiring
See Appendix B for a listing of output module connections.
DANGER
: Turn off the unit, disconnect A/C power and unplug the 14 pin I/O connector on the
side of the unit (if installed) before any wiring modifications.
3.6.1 Standard Output Module Wiring
The standard output modules included with the system require an external 24V supply connected to the
DOD64-FTIR to supply power for the outputs. Use only AWG22 to AWG18 twisted wire (wire sizes UL1015 and
UL1007) Strip from 0.25” to 0.31” (
6.5mm to 8.0mm) from each wire to insert into the connector. To connect
the wires to the spring-loaded output connector:
•
Insert the screwdriver into the square shaped hole which will open the round hole for the wire.
•
Continue to hold the screwdriver while inserting the wire into the round shaped hole.
•
While holding the wire in place, remove the screwdriver which closes the clamp onto the wire.
•
IMPORTANT
: Be sure the wire is inserted completely into the hole. Failure to do so could result in
system failure, electrical shock.
•
To remove a wire, re-insert the screwdriver in the hole as described in step 1 and gently pull the wire
out while the spring is compressed.
3.6.2 I/O Connection Details
Each analyzer tray (16 or 32 point) has its own output module section and each section is coupled together
with an EK1101 module. Two different power sources are used for the module. Power to operate the module
itself is supplied by the DOD64-FTIR power and prewired by DOD Technologies - Do NOT remove. Power for
all outputs must be supplied by the customer on pins 6 & 7. See Appendix B for detailed information.
IMPORTANT
: Verify that all I/O unit terminal screws are securely tightened even if they are not used.
