LCD backlight burns out
Check all cable connections to LCD, distribution board and computer
module. Make sure the power is turned off before doing so.
Faulty E-stop switch
It can be stuck open or closed (pressed). If it is stuck closed the
pendant will need to be replaced because the user will have no way to
get rid of the message. If it is open it will allow the machine to still
operate but it will be unsafe for the user. The pendant will still need to
be replaced. The E-Stop reset button may need to be pressed.
Overlay failure (keys on
pendant)
Certain buttons on overlay do not work. Do code 81 to verify each key
beeps.
Low voltage to pendant or
current spikes
1 amp fuse in pendant blows. Pendant will not turn on.
Slave board not functioning
Machine will not run. If under Code 33 it says “demo,” it means the
slave board is not functioning.
4.3.1 Checking Floppy Drive by Formatting a Disk
1.
Find a new disk and install in floppy drive.
2.
Install keyboard into middle port.
3.
Press CTRL ESC to get to start menu.
4.
Press R for run.
5.
Type Format a: - press enter.
6.
If the format works your disk drive is working. If format does not work, reboot
control and see if it now works. If it does not work replace the computer
module.
7.
Press ALT ESC to get back to PT4 software.
4.4 Motor Diagnostics
The Motor subsystem is comprised of 2 parts: The Motor Encoder and the Motor.
The motors are powered by 110 VAC voltage. The servo driver is also an integral
part of servo system, which is discussed in detail in the next section.
WARNING!
Do not work with the motors unless the power is disconnected from the machine. The motors
are run by 110 VAC. There is possibility of death by electrocution!
Rarely do both the X and Z motor/servo systems fail at the same time and in the same
way. So, if your problem is occurring on both axes, its source is probably somewhere
else.
4.4.1 Cable Connections
Check the motor cable connections on the cable breakout box. Verify there are no pushed
in pins on the connector.
4.4.2 To Check the Motor Encoders
If the motor encoder inside the motor has failed or is not reading the machine will fault
out on that axis. Do the following to verify this problem:
Run Service Code 100 or 131. This will display on the DRO if the motor encoder is
counting. If this axis does not count, the encoder is not counting. This means either the
encoder or the cable is the problem. Visually check the cable for any problems. If the
encoder has failed the motor must be replaced.
