I-LEB Beam-Break Converter Instructions & notes
revision 1.2 (Jan 2007)

Please read these notes, ask if you have questions.

Frame/Body Disassembly:
- To disassemble the frame from the body, first remove the battery as normal then unplug the wire harness from the lower board. Slide the frame off, away from the body, like normal.
- For regular maintenance, it’s not necessary to remove the wire harness / I-LEB from the upper board. It’s also a good idea to keep the new eye harness plugged in as well. You need only remove these if you’re performing a complete disassembly, which is rarely needed (if ever).
- Never try to remove the beam-break eye harness from the connector while the frame is installed. 

The I-LEB converter is spliced into the stock wire harness, and plugs into the upper and lower boards in the same way as the stock. However, unlike the stock wire harness, the correct plug must be inserted into the corresponding board (upper or lower). The new wire harness is designed to situate the converter at the rear of the marker before plugging into the lower board.
If the wire harness is plugged in upside-down, nothing will be damaged, however the eyes won't work.

When reinstalling the frame to the body, be careful not to catch the wire harness on the powerswitch actuator button inside the frame. Use a pick or small allen wrench to push the wires away for a clean reassembly. The wires in the wire harness may push up on the powerswitch actuator button; if this happens it may be a little more difficult to push. Again, use a small tool to push the wires out of the way.

Connectors:
- The wire harness uses connectors with "protrusions" which are small tabs that stick out the sides. These tabs can be used for easier removal than the older wire harnesses (that lacked protrusions).
- The beam-break wire harness also uses protrusions, which I strongly suggest you use for removal. As described above, only unplug the eyes from the converter when the frame is removed from the body.
- The beam-break connector is polarized so you can only plug it in one way. However, don’t force it in if it doesn’t go in initially. This usually means it’s upside-down.

Operation:
- During normal operation, the emitter eye will be active while the board is on, and disabled when the board is off. Please note that it’s normal for the emitter to be dim if you switch your board’s eye mode to eyes-off (some boards turn the emitter off, but not all).
- If the emitter eye never lights up and you know you have visible eyes installed, there is a wiring problem. Check the connections and be sure you have the eyes on.

Please note that some boards pulse the emitter eye (turning it on and off rapidly). This is perfectly normal; it’s a feature designed to save battery power.

Repair:
If you have any questions or problems please contact Ydna at ydna@zdspb.com. The converter’s electronics are warranted against damage but you will need to send the marker in for diagnosis and repair.

Do not attempt to disassemble the beam-break converter in any way. It is designed in a very specific manner and cannot be reassembled once taken apart.
