DOUG FLEENOR DESIGN, Inc. Model DMX8DIM Installation and Operations Manual Doug Fleenor Design, Inc.
Product description The DMX8DIM is an 8 channel, 250 Watt dimmer. It is fed by a single 120VAC 20A branch circuit. Each output is protected by a self-resetting poly-fuse. Each of the dimmers can be separately controlled using a typical DMX512-based lighting controller. The DMX8DIM is housed in a standard NEMA1 electrical enclosure. Knockouts are provided on the top and bottom of the enclosure for easy installation. Cables may enter the sides of the enclosure by using standard chassis punches.
• Safety grounding must be maintained through this product. Metallic conduit may be used for grounding if it is appropriately bonded to the enclosure. The ground terminal on the line input and all output terminals may be used for grounding conductors. All such terminals are internally bonded to the enclosure. Power input (line) wiring Supply the DMX8DIM with a protected branch circuit of no more than 20A. The power input terminals on the DMX8DIM are rated for #12AWG copper wire (maximum).
Control cable wiring Control cabling must enter the enclosure and route directly to the control input terminals. The installer must secure low voltage control cabling such that it can not come in contact with high voltage line or load wiring. Control cable terminal block The DMX512 control signal is connected to the DMX IN terminal block. A cable appropriate for use with DMX512 must be used. Examples include Belden 9829, Belden 9729, or their equals by other manufacturers.
Setting the address switches The ADDRESS switches are used to select the DMX512 starting address for the DMX8DIM. Each switch represents a value as marked on the circuit board. The address switches should be turned on in a combination whose totals equals the desired DMX512 starting address. For example, if the desired starting address is 25, the switches representing the values 16, 8, and 1 should be turned on. The rest of the address switches should be off. The photo below shows this setting.
Setting the non-dim mode switches The NON-DIM switches are used to select the behavior of each output. When the NON-DIM switch for the associated output is off, the dimmer will have full range dimming control from zero to full intensity. When a NON-DIM switch is on, the associated output can only be either on or off. There will be no dimming action. The output will turn on full when the associated DMX512 input channel is raised above 1%. It will turn off when the DMX512 channel is brought below 0.5%.
