Troubleshooting the Conveyor

Agilent U1840A Medalist sj5000 Hardware Manual
• Conveyor will not load a board
• Board passes straight through the machine and will not stop
for inspection
• In-Position sensor sensitivity
• Failed boards will not exit the system
• Conveyor belt(s) reverse direction unexpectedly
• Clamp motor continuously rotates
• Board is not clamped
• Inspection yields fiducial mis-reads
• Conveyor will not run
• Conveyor 1 will not run
• Conveyor will not run because there is no output from PLC
• Drives will not move/home/move to a given width
• Cannot manually adjust the width of the conveyor rail
• Conveyor rails will not align properly
Conveyor will not load a board
• The SMEMA cable may not connected. Check the connection
at the upstream conveyor and the back of the sj5000.
• The sj5000 may believe there is a board already present.
Check that all three sensors are not flagged by either a board
or gantry. All sensors have sensitivity potentiometers that
may be set too sensitive and are identifying the rail or other
hardware as a board. This can be verified by reviewing the
input PLC modules.
Board passes straight through the machine and will not stop for
inspection
• The sj5000 is in pass through mode. Check the RAIL
switch(es) on the switch plate and ensure it is set to INSP
(inspect).
• The In-Position sensor is not being flagged as the board
passes through the sj5000. This can be verified at the PLC
module or by manually flagging the position sensor.
