Table 3-II MPC I/O Connector Signals

MPC I/O Connector Pinout

The MPC I/O connector is a two-piece pluggable termi-

nal block connector.

Table 3-II lists the signal names and descriptions, with

more detailed descriptions listed below.

Pin 1 (Setup Bit 0 Input)

Setup Bit 0 is the least signicant bit used to select differ-

ent probe channels when a Multi-Probe Control (MPC)

Interface is used. This MPC control bit is used on all

MPC systems.

Pin 2 (Setup Bit 1 Input)

Setup Bit 1 is the second least signicant bit used to se-

lect different probe channels when a MPC Interface is

used. This MPC control bit is used on MPC systems with

three or more channels.

Pin 3 (Setup Bit 2 Input)

Setup Bit 2 is the third least signicant bit used to select

different probe channels when a MPC Interface is used.

This MPC control bit is used on MPC systems with ve

or more channels.

Pin 4 (Setup Bit 3 Input)

Setup Bit 3 is the second most signicant bit used to se-

lect different probe channels when a MPC Interface is

used. This MPC control bit is used on MPC systems with

nine or more channels.

Pin 5 (Input Common) [Electrically connected to

Pin 13 on System I/O connector.]

Pin 5 is electrically isolated from chassis ground. Using

sourcing (PNP) output drivers, this common line would

be connected to the automation system ground potential.

Using sinking (NPN) output drivers, this common line

would be connected to the automation system positive

supply voltage

output. Refer to Section 6 for wiring

examples to connect input signals.

Pin 6 (MPC Ready Out)

Pin 6 is a non-isolated digital NPN status output that

activates when the MPC control is ready to accept

changes on the probe selection control bits and ready to

start the next MPC welding cycle. This output will be an

open circuit when the MPC system is not ready to accept

changes to control input signals, and it is able to switch a

sourcing PNP input ON or OFF.

Any changes will be ignored until this status output signal

activates to the ready state. This status output signal will

also be open (MPC NOT READY) if a fault condition

is detected inside the MPC system. If this status output

will not activate, check for a RED fault status indication

(SYSTEM STATUS LED) on the front panel of the MPC

module.

Pin 7 (Output Common)

Pin 7 is connected to chassis ground. The non-isolated

NPN status output signal can drive an isolated PNP input

on the automation control system.

Refer to Section 6 for wiring examples to connect output

signals.

NOTE

The Input Common Pins: Pin 13 of the

System I/O connector and Pin 5 on the

MPC I/O connector are both electrically

isolated from chassis ground, but they

are connected together. Both of these

signals must be connected to the same

voltage potential, either automation

system ground or the automation sys-

tem positive supply voltage.
