MPC Probe
The cable connection diagram for connecting the
Multi–Probe Controller module is shown in Sec-
tion 3 in Figure 3–6. The flow chart for the Pro-
cess Control menu with a Multi–Probe Controller
installed is shown in Figure 7–12. If you do not
have a Power Output module installed, the Energy
Weld Method menu will not be displayed.
The Multi–Probe Controller (MPC) flow chart
adds three options to the basic Hand Probe flow
chart shown in Figure 7–7.
1. An AUTO STOP option is included which can
be enabled or disabled.
2. A delay time value (T
delay
) can be entered for
untimed operation.
3. A weld method called GROUND DETECT is now
available. This method requires values to be
entered for the maximum weld time (T
max
) and
for a parameter called scrub time (T
scrub
).
AUTO * STOP Option
This menu is shown in Figure 7–13. To use this
option, move the SH704 jumper block to JU715
(see Figure 5–12). Use the down arrow key to se-
lect
ENABLE and press ENTER to continue.
When Auto Stop is enabled, a signal on pin 9 of the
HD–15 SYSTEM IN connector will be recognized.
This permits external automation equipment to stop
the welding cycle. If Auto Stop is set to disable, then
the signal will be ignored. If the SH704 jumper block
is left in the End–Of–Weld factory default position
(JU716), only the welding is stopped. Any pro-
grammed Hold or Afterburst (discussed later) will
still be executed regardless of the Auto Stop mode.

* These values can be set to zero, but will not produce any
output. The values listed represent the resolution and are
the smallest values that will produce any output signal.
