Adjusting Nozzle Vacuum Sensors
The TM-402’s
Nozzle Vacuum Sensor
is setup before the machine is shipped. It may occasion-
ally require adjustment depending on vacuum sensitivity and the type of part that is being pro-
cessed.
If the TM-402 places “empty” pockets (i.e. places as though it held a part when it did not) or
returns a picking part error when it picked a part, the vacuum sensor’s threshold point probably
needs to be adjusted.
Vacuum Sensor Settings
1.
Close the enclosure doors, then open the
Head Setup Tab
.
2.
Press the
Pick Part
button to activate vacuum and pick a
part. Observe the vacuum sensor indicator which is located
on the
Pick & Place Head
above the nozzles. The numbers
should be lit in
green
with components on the nozzle and
red
if components are not.
3.
If the sensors require adjustment, Press the blue
Set
button
once. The sensor will alternately flash
P_1
and the current
value.
4.
Use the
Up/Down Arrow Keys
to adjust the sensor as
needed with components both on and off of the nozzles..
5.
Press the blue
Set
button again to exit back to normal opera-
tion.
