Troubleshooting guide

Appendix B if the container is open, or Appendix C if the container is closed (to allow for more
side play in the spindle). The increased side play may allow the cam magnet to get closer to
the reed switch. If the container is open, check the reed switch to make sure it is not tilted to
one side. Replace the drive cam with a new one and try the lock. If the container is closed,
remove the dial as stated in Appendix C and bias the spindle away from the ribbon cables
(opposite the direction shown in Fig. 5).
CAM MAGNET
Same approach as the reed switch.
BACK COVER ASSEMBLY
1. Remove back cover. (Appendix A)
2. Replace the back cover assembly with a new one.
DIAL BLOCKED TO THE RIGHT AFTER “OP”
After executing the combination and with “OP” displayed, the X-07 dial is blocked to the right.
When the dial is turned back to the left and “OP” goes out the dial is free turning and the
combination can be reentered.
POSSIBLE CAUSES
1. Stepper motor gear
2. Mechanical relocker
3. Magnetic relocker
STEPPER MOTOR GEAR
If the stepper motor does not take a full 36 degree step when the X-07 processor outputs the
signal to step the motor, then the stepper motor gear teeth will not be properly aligned to the cam
drive gear teeth. The cam drive gear teeth and the stepper motor gear teeth will not mesh
properly and may be hitting on top of each other creating a block to the right. If this is the case,
we may be able to move the stepper motor a slight amount by inducing some vibrations with a
dead blow hammer while walking the dial into and out of the block. If you back up too far the
cam will reset the stepper motor to the home position and you will lose the block. Hold and turn
the dial with one hand while hitting the container with the other. You can increase the intensity
as time passes. Start out cautiously and increase the intensity as time passes.
MECHANICAL RELOCKER
The thermal fuse pad on the back cover assembly compresses the relocker lever spring and lifts
the relocker lever up and away from the slide assembly tab. When the relocker lever is held up,
the slide assembly tab will move under it without any resistance. If for any reason the relocker
