Problem Check Comments/Corrective Action
Monitor has AC power.
Power plug is plugged into
monitor and AC assembly.
Power on, LED on.
It is possible to plug the machine monitor or some other monitor directly
into the embedded PC board in the VME chassis, bypassing the VGA
cable in the machine.
If another machine or an office PC is available, try plugging the machine
monitor into it.
Fuse or circuit breaker OK.
VGA cable connected and
good.
+5 volt DC Power Output
from power supply.
If the monitor displays the BIOS screen (test size memory), the embedded
PC and monitor are probably OK, therefore, the software or drivers are at
fa ult.
If the monitor and cable check out, the embedded PC might be defective.
Check for +5 and +12 volts at
hard drive connectors.
Check wire cables for
breakage, wrong polarity,
poor connections.
Note: The drives and embedded PC are very similar to standard PC
compatible devices and use similar troubleshooting techniques.
Check board using IM
Diagnostics
IM Diagnostics bypasses the CPU-30, which usually supervises the
operators of the motion control board. Reference the electrical drawings.
Check encoder function
Using IM Diagnostics, cause the axis to move. (Use care to not run into
another assembly or into a limit switch.)

Troubleshooting Table - Pneumatic System
The following table lists possible error scenarios for the pneumatic system.
Probable Cause Corrective Action
Air filter sediment bowl full. Drain and clean sediment bowl.
Moisture contaminated in house air
supply.
Correct factory air supply to machine.
Drip rate set too high.
Set the drip rate as specified in the
Preventive Maintenance Schedule in the
Base Machine Procedures document.
Pneumatic system oiler failed.
Replace pneumatic system oiler and set
drip rate.
Drip rate set too low.
Set the drip rate as specified in the
Preventive Maintenance Schedule in the
Base Machine Procedures document.
O il res erv oir em pty . Refill oil res ervoir.
Pneumatic system oiler failed.
Replace pneumatic system oiler and set
drip rate.
Source air pressure too low.
Set factory air pressure to machine to
80 psi minimum.
Seals or o-rings are dry or dirty. Clean, lubricate, and replace if needed.
Control valve sluggish. Clean, lubricate, and replace if needed.
Drip rate s et too low. Adjus t drip rate as s pec ified.
