2.2 Sensor Installation Guidelines
Installation of the Micro ADM™ is a simple 5-step process regardless of the
selected mounting method.
1. Feed the Positive welding cable through the Micro ADM™ Current
Sensor opening. The diameter of the opening will accommodate a 22
mm cable. If the crimp terminal is too large to fit through the opening
then it must be removed and another terminal installed after the cable
is passed through the opening.
2. Feed the wire through the Micro ADM™ Wire Feed Speed Sensor
inlet. Push down on the pressure release lever located on the top of
the sensor while feeding the wire through the guide rollers and out the
other side of the sensor. Feed the wire into the wire drive motor as
you would normally. If using the quick disconnect fittings to mount the
sensor, connect one end to the wire drive motor quick disconnect
fitting. Insert the wire liner quick disconnect fitting into the other end of
the sensor.
If using the optional mounting brackets, install the
sensor at the desired location. Install an insulated wire liner or conduit
assembly (Maximum length of 1 meter) for support of the wire from the
Micro ADM
™ to the wire feeder inlet.
3. Connect the Shielding Gas line to the Micro ADM™ Gas inlet. A barb
T-fitting is provided to facilitate the installation of the Gas Line. Cut the
Gas hose and install each end on to the 1/8” NPT 90° elbow. User to
supply the necessary adaptor. Make sure to check for gas leaks after
the hose clamps are installed.
4. Use the two Conductors (18 gage, 600V) provided with the Micro
ADM™ Sensor to connect the Micro ADM™ Voltage Sensor to the
welding system. Route the RED conductor (3’ long) from the Positive
(+) terminal of the Voltage Sense Terminal block to the Positive
welding cable connection point (at the Torch or Wire Feeder). Route
the BLACK conductor (25’ long) from the Negative (-) terminal of the
Voltage Sense Terminal block to the Negative welding cable
connection point (at the Work piece ground point).
5. To connect the Sensor Cable (A3W0327) to the Micro ADM™, insert
the connector into the Micro ADM™ Sensor Cable receptacle until it
“Clicks” and locks into place. Connect the other end to the appropriate
weld data acquisition system or PLC. To remove the Micro ADM™
Sensor Cable, pull back on the locking barrel of the connector plug
while pulling the plug from the receptacle. A diagram of the
connections for the cable can be found in Appendix B.
