DOUG FLEENOR DESIGN, Inc. Model DMX24DIM Installation and Operations Manual Doug Fleenor Design, Inc.
Product description The DMX24DIM is a 24 channel, 100 Watt per channel dimmer pack. It is fed by a single 120VAC 15A branch circuit. Each of the dimmers can be separately controlled using a DMX512-based lighting controller. The DMX24DIM is housed in an enclosure suitable portable use or for mounting in a standard 19" rack. The DMX24DIM occupies 1U of rack space. Safety warnings • There are no user serviceable parts in the DMX24DIM. Servicing should be referred to qualified service personnel.
Power input (line) wiring The DMX24DIM should be connected to a standard 15A 120VAC grounded outlet. The outlet must be protected by an appropriate over-current protection device. Note that if all outputs are loaded to 100W and all outputs are set to full, the 15A branch breaker feeding the DMX24DIM will trip. If the application requires all dimmers to be fully loaded, the DMX24DIM must be fed by a 20A branch breaker and an appropriate receptacle.
Setting the address switches The front panel address switches are used to select the DMX512 starting address for the DMX24DIM. Any starting address from 1 - 512 can be selected. The address shown on the switches will be the DMX512 address for the first dimmer output. The next 23 consecutive DMX512 levels will be applied to the remaining dimmer channels. When the address switches are set to 000, the DMX24DIM operates as if the address switches were set to 001.
Loss of DMX512 signal Upon loss of the DMX512 input, the DMX24DIM will begin fading all of its outputs to zero. The fade out time is about 60 seconds from the loss of signal. Maintenance and cleaning The DMX24DIM’s fan intake on the front panel and the exhaust ports on the left side of the enclosure should be cleaned periodically (see photos below). The frequency of cleaning depends upon the working environment and the amount of time the dimmers are running.
