POWER WAVE® AC/DC 1000
A-21
EXTERNAL I/O CONNECTOR
The Power Wave AC/DC 1000 is equipped with a ter-
minal strip for making simple input signal connections.
(See Figure A.2a) The terminal strip is located under-
neath the spring-loaded cover, and divided into three
groups:
FIGURE A.2a
Trigger group, Cold Inch Group and Shutdown Group.
When the Power Wave AC/DC 1000 is controlled via
DeviceNet, the Trigger and Cold Inch Groups can
interfere with the welding sequence and should not be
used.
All inputs use "normally open" logic except the shut-
down group. The shutdown inputs use "normally
closed" logic, and are always enabled. Shutdown2 is
typically used for signaling low flow in the water cool-
er. Unused shutdowns must be tied to the +15V sup-
ply for the shutdown group. Machines are shipped
from the factory with jumpers installed on both shut-
down inputs. (See Figure A.3)
Notes:
1. Activating the Trigger or Cold Inch group inputs on
a system without a user interface or other means
of configuring the Weld Sequencer will result in
default values for Weld Mode, WFS and Work
point settings.
2. Trigger and Cold Inch group inputs may be rede-
fined as "Weld Profile Selections" by Production
Monitoring software (see Production Monitoring
Literature for details)
3. On later machines, pin 12 has been redefined as a
gear ratio selection input. See “Setting the Wire
Drive Gear Ratio” for further information.
