EDI-120 Control Retrofit
for Electronics Diversified Inc. (EDI) Mark VII Dimmer Racks
Specifications

1.0 EDI-120 - GENERAL

1.1 EDI-120 is a direct retrofit kit specifically designed for facilities with existing Electronics Diversified Inc. (EDI) Mark VII dimmer rack(s) requiring new, reliable and cost-effective control electronics. EDI-120 is designed to upgrade existing dimmer installations to current dimming technology with options equaling or exceeding those of most new dimming systems. Designed for pin-to-pin compatibility with the Mark VII OEM factory dimmer control wiring, installation is both fast and easy. Facilities can upgrade to this state-of-the-art technology in minutes with only a screwdriver. The EDI-120is ETL compliant with UL 508 and CSA 22.2 safety approvals.

1.2 EDI-120 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 make any potential service requirements fast and easy with all wiring connections being "break-away" requiring no tools other than a screw driver for the four mounting screws.

1.5 Dimmer control outputs shall be designed for precise and reliable control of the existing Mark VII dimmer modules. It shall never be necessary to adjust ramp circuits for proper dimmer output.

1.6 The EDI-120 shall accept dual independent DMX 512-A digital data protocol inputs allowing industry wide compatibility with modern control consoles. Both DMX inputs shall be independently opto-isolated from all other control circuitry, as well as from the DMX output ports. An internal protocol manager shall allow priority management, offset start addressing or merging of both DMX inputs.

1.7 An optional Ethernet node shall support a wide range of communication protocols including Net2, Strand, ArtNet, ACN (Net3) and Pathport. Automatic recognition will permit interface to most popular lighting control protocols. It shall not be necessary to assign protocol.

1.8 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.

1.9 Rack thermal protection shall be employed to interface with the existing dimmer module over-temp sensors and wiring. An active over-temp input from any dimmer shall illuminate a red warning LED. An internal EDI-120 temperature of 65°C shall immediately disconnect of all dimmer control outputs.

2.0 CONTROL PCB

2.1 The EDI-120 control electronics shall be capable of controlling up to 120 dimmers in the Mark VII dimmer cabinet. Advanced state-of-the-art voltage regulation hardware and software will ensure >1% all dimmer outputs. The EDI-120 will operate with a voltage input range of 85-264VAC at 50 or 60Hz.

2.2 The EDI-120 shall be capable if memorizing and storing up to 24 presets 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 24 scenes. Each scene shall have a selectable fade time from 0-99 seconds.

2.3 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.

2.4 It shall be possible to assign (patch) any dimmer control signal to any module position in the cabinet, thereby allowing dimmer modules of any rating to be used in the same cabinet.

2.5 EDI-120 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 on the EDI-120 shall not exceed 1 Watt.

2.6 The EDI-120 shall allow "back up" of all system configuration data. All data shall be protected from power failure by EEROM for a minimum of 100 years.

2.7 The EDI-120 shall contain a removable memory dongle 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 rack programming or system parameters.

2.8 The EDI-120 shall accept up to 4 (four) analog inputs with the ability to be assigned to any of the 120 dimmer outputs in the system. Each analog input shall be selectable as either "Normal" mode (0-10VDC input) for dimmed applications or "Load Shed" mode (5VDC trigger) for power management interface to building management systems (BMS). The analog inputs shall function in a pile-on or HTP mode with the DMX control signal.

2.9 Dedicated dry contact inputs shall be provided for BMS, HVAC, security and fire alarm. Active security input shall "flash" any programmed dimmer outputs to a selectable level at a rate of 1Hz. Active fire alarm input shall bring any programmed dimmers to a selectable level and override all incoming control data.

2.10 Each individual dimmer in the dimmer cabinet 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).

2.11 The face of the EDI-120 shall include an LCD display and momentary push buttons for function select, parameter setting and feature monitoring. All programming shall be via a user-friendly, intuitive and self-prompting menu structure. It shall not be necessary to use a PC or any external programming devise to configure or set-up any function of the EDI-120.

2.12 The EDI-120 shall employ the "system-on-a-chip" advanced "3000 Series" digital technology. Such electronic circuitry shall permit real time signal monitoring and status LED indication to allow easy setup and remote troubleshooting. The EDI-120 shall permit configuration/monitoring of the following within the Mark VII dimmer rack:
