Controller Board DIP Switch
These switches will normally be set to the open position.
All of these functions are controllable from the front panel
by the soft switches, described in the Operation chapter
of this manual.
The controller board also has a DIP switch (reference
designator number S1) which is used to configure the
board to operate in an application specific mode. The DIP
switch can be used to run the diagnostic routines. The
diagnostic selections are described in the Troubleshooting
chapter of this manual.

NOTE
OPEN is sometimes called ON or 1 and should
be considered the same state. Conversely, not
OPEN will be referred to as CLOSED, OFF, or
0.
Diagnostics Select — When this switch is in the CLOSED
position, the diagnostics routines are executed. These
routines are described in detail in the Troubleshooting
chapter of the manual. In order to use the control panel
operationally, this switch should be OPEN.
Weld Sub Segment Enable—This DIP switch is enabled
only when the SSE soft switch is set to HAr. When this
switch is in the OPEN position, the multiple Weld Sub
Segment feature of the control panel is enabled. This
feature is used to change the weld parameters because
of a discontinuity in the work. This feature is described in
the Semiautomatic Operation section and Auxiliary
Interface Operation section located in the Operation
chapter of this manual. When this switch is CLOSED, the
control panel will ignore instructions to use the next
sequential Weld Sub Segment parameters.
Trigger Hold Enable — This DIP switch is enabled only
when the PdE soft switch is set to HAr. When this switch
is in the OPEN position, the Trigger Hold feature for
semiautomatic welding is enabled. When this switch is
CLOSED, the triggering mechanism is called deadman,
meaning that for the panel to continue welding, the switch
must continue to be pulled. The trigger hold feature allows
the welder to initiate the weld with a momentary pull of
the switch, and terminate the weld with another
momentary pull of the switch. The full description of this
process is described in the Semiautomatic section of the
Operation chapter of this manual. This feature can also
be selected from an optional switch on the front panel.
Interface/Suppressor PCB Assembly
(Refer to Figure 2-10)
The Interface/Suppressor PCB Assembly (I/S Board) is
the link between the external, Amphenol type connectors,
and the internal ribbon and discrete wire connectors.
Several signals are filtered in order to reduce electrical
noise coming into the control panel.
There are four jumpers on the I/S board. The jumpers are
used to configure the board for various products that this
panel may be used with. Refer to Figure 2-10 for jumper
locations.
100050-2 Specification HMC-410
The 100050-2 HMC-410 is a special configuration of the
HMC-410 that has an RS-232C interface installed into it
and the 171238-19 software kit installed into it. This
configuration has a 870200-2 board installed that provides
the RS-232C circuitry and a 9 pin D-Sub connector.
Contact the factory for additional information in using
the RS-232 interface.
