8. Connect input supply voltage per the Auxiliary Input
Power Connection Instructions listed earlier.
9. The relays could also be used to provide contact
closure for any interfacing signals out using the nor-
mally open contacts. An external auxiliary supply
voltage would not be necessary to use the relays as
hard contact closure out signals. NOTE - The CR1
relay as shipped does not have AUX leads connect-
ed to it. This relay has two normally open contacts
that close at the start of the weld cycle and open at
the end of the weld cycle. These hard contact clo-
sures could be used as a signal out when interfac-
ing to PLC’s or custom controls.
Shutdown Inputs:
The POWER FEED™ 10A CONTROLLER has two
shutdown inputs available on the terminal strip. These
are independent, normally closed inputs that can be
used for limit switches, PLC inputs, etc, in order to
shut down the welding operation for any reason.
Shutdown #1 is located on terminal strip blocks #24
and #25. Shutdown #2 is located on terminal strip
blocks #26 and #27.
1. Remove all input power to the POWER FEED™
10A CONTROLLER including any auxiliary power
supplies.
2. Remove the wire duct cover to gain access to the
leads on the right side of the terminal strip.
3. Remove one of the plug buttons located on the bot-
tom of the POWER FEED™ 10A CONTROLLER
control box and install some type of strain relief for
the auxiliary control leads.
4. Connect the external shutdown circuit to either of
the shutdown terminal blocks, #24 & #25, and/or
#26 & #27. A normally closed circuit must be con-
nected – the POWER FEED™ 10A CONTROLLER
will recognize an open circuit as a shutdown com-
mand.
5. Remove the shorting jumpers imbedded in the cen-
ter of the terminal strip with a small screwdriver for
the shutdown circuits to be used.
When a shutdown input is received, all welding will
stop and an error message will be displayed on the
POWER FEED™ 10A CONTROLLER. The shutdown
circuit must be closed before resetting Controller. To
reset the system, the Mode Select Panel display will
prompt the user to press the left Mode Select Panel
Pushbutton.
Shutdown #2 can be configured for Output Lockout
mode by enabling option P.21 in the Setup Menu
(Refer to Section B, General Setup Mode Options).
when the input is opened, output is disabled, but cold
feed of wire is still possible.
Stop Input:
The POWER FEED™ 10A CONTROLLER has a Stop
Input available on the terminal strip. The Stop Input
will work just like pressing the STOP Pushbutton. This
circuit is in parallel with the STOP Pushbutton located
on the Switch Panel. Unlike the Shutdown Inputs,
which completely shutdown all welding and auxiliary
equipment, the STOP Input will allow all welding and
auxiliary motion to continue based on the END
OPTIONS configurations in the POWER FEED™ 10A
CONTROLLER.
1. Remove all input power to the POWER FEED™
10A CONTROLLER including any auxiliary power
supplies.
2. Remove the wire duct cover to gain access to the
leads on the right side of the terminal strip.
3. Remove one of the plug buttons located on the bot-
tom of the POWER FEED™ 10A CONTROLLER
control box and install some type of strain relief for
the auxiliary control leads.
4. Connect the external Stop Input circuit to terminal
blocks #28 and #29.
The Stop Input is not necessary if the POWER
FEED™ 10A CONTROLLER is configured for Remote
Interfacing, mentioned earlier, due to the fact that the
Stop circuit can be accessed, in this configuration, on
terminal strip blocks #39 and #41. The Stop Input was
intended to be used when the Switch Panel is still
included in the system, either on the Controller, or in
the Pendant.
Note: the STOP circuit only needs a momentary clo-
sure to be recognized by the POWER FEED™ 10A
CONTROLLER. If the STOP button is held, the
START and INCH buttons are not recognized.
