All the connections remain the same as per previous PCB revisions with the exception of the thermocouple
connection. In order to attach the thermocouple to the PCB, the thermocouple has to be attached to a TC
connector as per following instructions:
TC connector & Thermocouple assembly
Detach wire cover with
Screws 1 and 2.
Cut Ground wire.
Trim wires at 0.2 inches (5mm).
Insert wires through the TC
connector’s rubber o-ring.
Attach Yellow wire at the “+” sign of the TC connector and Red
wire at the “-“ sign of the TC connector using Screws 3 and 4.
Position the rubber o-ring into its groove.
Reattach wire cover.
If serial cable is required (external printer cable replacement), attach adapter bracket, DB25 to DB9, to the
printer connector opening on chassis using 2x screws. Attach DB9 connector from the serial cable to the
adapter bracket and the 14-pin connector to Rev 7 PCB at connector J107.
