Inside the EMI3M
|
Your EMI3M module is configured specifically for your dimming system. It contains six internal user-replacable fuses and a single set of jumpers. Data FusesSix fuses are installed inside the EMI3M to protect your system. If there is a short (excess voltage) in the data stream, the fuses in the affected phase will fail. Two fuses are assigned to each phase. (See diagram to left.) Main/Auxiliary JumpersThese jumpers consist of two sets of three vertical pins on the circuit board at location J3. Most L86 Installation Racks, and all L86 Touring Racks are set to Main (center and top pins connected on both sets). If you are replacing a malfunctioning EMI3M in your system, be certain to adjust the jumper settings at location J3 on the spare so they match the settings on the original module. (See illustrations to left.) If you have any questions, please contact ETC Field Service.
