1.0 DPC-12 & DPC-24 - GENERAL
1.0 Digital Pack Controllers (DPC's) - GENERAL
1.1 On power up, DPC's shall default to "Basic Mode" of operation permitting access to only three menus; DMX Address, DMX A Termination and DMX B Termination. DPC's advanced features access shall require a specific button push sequence in order to protect all programmed system configuration/data from accidental or unauthorized access.
1.2 DPC's shall employ a unique "lamp warming" feature that extends lamp life by limiting the in-rush current from the dimmer to cold lamp filaments by up to 70%.
1.3 An LCD user interface for ease of set up and monitoring. All programming shall be via a user-friendly, intuitive and self-prompting menu structure. No PC or special software will be required.
1.4 Modular design of the unit shall permit "direct plugging" into the existing OEM rails and connectors.
1.5 Hi-resolution dimmer control outputs shall be designed for precise and reliable control of the existing CD80 dimmers. It shall never be necessary to adjust ramp circuits for proper dimmer output.
1.6 The DMX512 input ports shall accept two independent sources of DMX512 data protocol simultaneously from the system control console(s) or architectural control unit(s). The DMX inputs shall comply with USITT DMX512-A (ANSI E1.11 - 2008), standard protocol for digital data control.
1.7 An infrared LED link shall be provided on the control module face panel. This interface will permit hard copy printouts of all programmed data via an optional hand held infrared printer.
1.8 Thermal protection shall be employed to interface with the existing dimmer pack over-temp sensors and wiring. An active over-temp input shall illuminate a red warning LED. An internal processor temperature of 75°C (135°F) shall immediately disconnect all dimmer control outputs.
2.0 CONTROL PCB
2.1 DPC-12 control electronics shall be capable of controlling 6 or 12 dimmers and DPC-24 up to 24 dimmers in the respective CD80 dimmer packs. Advanced state-of-the-art voltage regulation hardware and software will ensure >1% accuracy on all dimmer outputs. The DPC's will operate with a voltage input range of 85-264VAC at 50 or 60Hz with selective menu for 120V or 230V use.
2.2 DPC's shall employ 12 or 24 buttons selectable for either "Bump" or "DMX Snapshot/Preset" with adjustable LED intensity. DPC-12 and DPC-24 shall be capable of memorizing and storing up to 12 or 24 presets, respectively, in the form of a DMX "snapshot" or individually programmed via the keypad. Scene playback shall be seamless on loss of DMX as well as allowing high resolution fades between all scenes. Each scene shall have a selectable fade time from 0-99 seconds.
2.3 Both DMX inputs ports shall be opto-isolated from all other control circuitry, as well as from the DMX thru ports. An internal protocol manager shall allow priority management, offset start addressing, or merging of both DMX inputs.
2.4 DPC's will offer compliance with the International Energy Agency's "One Watt Initiative" on stand-by power requirements (please refer to U.S. Executive Order #13221). Standby power shall not exceed 1 Watt.
2.5 DPC's shall permit "back up" of all system configuration data. All data shall be protected from power failure by EEROM for a minimum of 100 years.
2.6 DPC's shall contain a removable memory module to facilitate remote or off site back up of all system configuration and ease of future firmware upgrades. Control module swaps will be easy and fast with no loss of programming or system parameters.
2.7 Each individual dimmer output shall be capable of being assigned one of four dimmer curves: incandescent square law curve, direct curve, linear curve, or non-dim (50% threshold with a ±5% hysteresis).
2.8 DPC's shall support the following menu items:
Basic Menus (power up default access only)
2.9 The DPC face panels shall include a green LED indicator for power supply and microprocessor status. The LED, when illuminated, shall indicate normal operation, and when flashing shall indicate a hardware fault. A power supply or power failure, shall cause the LED to extinguish.
2.10 The DPC face panels shall include three green LED's for phase detect and two yellow LED's for data receive indication. Loss of accurate phase detect signal and/or invalid DMX512 data shall cause the corresponding LED to extinguish.
2.11 The DPC face panels shall include two red LED's for active alarm status or dimmer rack over temperature. Active inputs shall cause these cause the corresponding LED to illuminate.
2.12 A reset push-button shall be included on the face panel of the DPC's. Resetting the unit, whether by the reset button or power-up shall not affect any stored parameters or presets, and dimmer outputs shall automatically return to their former status.
2.13 All face panel buttons shall be blue LED back-lit with adjustable intensity.
2.14 All printed circuit boards (PBC's) shall be FR4/G10 with a UL 94V-0 Flame Class Rating.
