Note: All inputs and outputs are 24 volts.
INPUT PIN DEFINITIONS:
1- AN_MODE_ENABLE
AN_MODE_ENABLE input will activate the power unit analog interface mode.No other input /
output will work unless this input is set to high.
2- ARC_START
ARC_START input will start the welding process.
3- WIRE_FORWARD
WIRE_FORWARD input will drive the wire forward.
4-5-6 MEM0-MEM1-MEM2 (memory select bits)
8 memories can be selected (recalled) with pins 4,5 and 6.
Memory selection works as following truth table.

6- GND_IN
GND_IN is the common ground input of all inputs.
OUTPUT PIN DEFINITIONS:
NOTE: All output pins are drawn with relays and connected to the common output pin.
7- ARC_ESTABLISHED:
ARC_ESTABLISHED output will connect the common out pin when the welding process
begins.
8- TOUCH_SENSE:
TOUCH_SENSE output will connect the common out pin when the welding wire touches the
workpiece.
9- ERROR:
ERROR output will connect the common out pin when the power supply calls an error from
the machine.
10- COMMON_OUT:
COMMON_OUT is the common 24-volt input of all output. If you connect this pin to 24 volts,
they will give you 24-volt output when the relays are pulled.
11- RESERWED_OUT
RESERVED_OUT is reserved for future output requirement.
