Troubleshooting
A. Problem/Cause/Solution
1. Processor

DBS rocker switch does not light when switched on.
Cause: No power to the DBS.
Solution: Check power cord on back of unit. Check the Main Screen shows the
firmware version of the punch unit. If the firmware version is displayed, the
rocker switch is defective and should be replaced. If “Offline”, check all cabling
and proper connections, and check Fuse 1 on the processor back panel. If Fuse 1
is blown, replace Fuse 1.

DBS rocker switch is lighted, but the computer screen shows the punch
“OFFLINE”
Cause: The computer is not communicating with the DBS controller.
Solution: Check the connections between the computer and the DBS unit. Check
to be sure that the correct serial port for the RS-232 connection has been selected.
2. XY Stage

Plate nest does not index properly.
Cause: Mis-alignment between plate and punch.
Solution: Check to see that the plate is seated properly in the nest. Check the
plate is properly calibrated.
3. Punch Mechanism
 Punch won’t activate when footswitch is pressed.
Cause: No communication/footswitch not plugged in/fuse has blown.
Solution: If the plate has also stopped moving, check communication with the
DBS as listed above under “Computer shows punch OFFLINE.” If the DBS
operates properly in all other ways except for the punch, check if Fuse 2 on the
processor back panel is blown. If so, replace Fuse 2. If the fuse is O.K., check
footswitch operation.

Punch does not cut cleanly.
Cause: Punch is dull.
Solution: The punch head should be replaced or sharpened.

Punch does not retract properly.
Cause: Paper is trapped in punch plate hole.
