Introduction JS-ICON™ Architectural Dimmers represent performance and longevity at its finest! 16-bit high resolution fades provide smooth light control for the most demanding environment. Suitable for virtually any application where centralized dimmers are required, this rugged hi-density design allows for adjacent side-byside installation where additional dimming capacity is needed.
Characteristics • Power Requirements: 120/208 VAC 3Ø 5 wire up to 40A. Max. rating 14.4kW or 120/240 VAC 1Ø 4 wire up to 60A. Max. rating 14.4kW. • Power Termination: Terminal block input and ouput. • Environment: Temperature Range: 32°F (0°C) to 104°F (40°C) ambient. Humidity Range: 0% to 90% non-condensing. • Dimmer Capacity and Load Type: 6 x 2.4kW standard incandescent, quartz, and dimmable (SCR/Leading-Edge) electronic low-voltage fixtures.
Installation Mounting The JS-ICON™ 624 ARCH can be mounted to any wall surface capable of supporting its weight (35 lbs (15.9 kg) for each rack). Four 1/4” (6mm) screws or bolts are required to fasten the rack safely to the wall (see the drawing below for mounting locations and dimensions). To access the mounting locations, remove the contractor wiring access panel, remove the breaker panel, and open the hinged service bay door.
Installation Removal of the Hinged Service Bay Door The service bay door is hinged for easy access for low voltage wiring hookup of DMX and analog control inputs, as well as service or replacement of the Solid State Relays (SSR). This door may also be removed for additional access for installation mounting. 1. Disconnect the ribbon cable connection from the Precision Demultiplexer PCB. 2. Squeeze the two spring loaded pins together on each of the hinges. 3. Pull the door forward to remove.
Power Supply Connection Details Three-Phase Power Supply Input Earth Ground Input The JS-ICON™ 624 ARCH is capable of various 120V power supply configurations. Remove the contractor wiring access panel to locate the contractor termination section, where the required power terminals are located. Knockouts on the top and bottom of the chassis are provided for wire/conduit entry to the power terminals.
Neutral Power Input Power Supply Connection Details Neutral Power Distribution Block Neutral Input: Use 350 kcmil to #6 AWG copper wire only, rated for 90°C minimum. Torque to 31 NM (275 LB-IN). To Phase Reference PCB #18 AWG Wire Neutral Output To Load 1 - 6 Load Output: Use #4 AWG to #14 AWG copper wire only, rated for 90°C minimum. Torque #4 AWG to #6 AWG wire to 3.95 NM (35 LB-IN). Torque #8 AWG wire to 2.82 NM (25 LB-IN). Torque #10 AWG to #14 AWG wire to 2.26 NM (20 LB-IN).
Control Input The JS-ICON™ 624 ARCH accepts both DMX 512-A protocol and analog 0-10VDC. These control inputs are configured for HTP (highest takes precedence) operation. DMX Data Input and DMX Data Thru is connected via internal breakaway type connectors. Analog 0-10VDC is connected via internal breakaway type connectors (see diagram on page 12). POWER/DMX IN ID RF OUT RADIO CHANNEL RESET Wireless DMX (WDS) is optional for all JS-ICON™ Series dimming models.
System Configuration and Setup 1. SETTING THE DMX START ADDRESS Select the desired DMX start address for the JS-ICON™ via the three rotary DMX START ADDRESS SELECT SWITCHES located on the panel of the rack (as pictured on the previous page). This start address is selectable in single channel increments from 001 through 512. All dimmers within a given JS-ICON™ will numerically/incrementally follow the selected start address for a total of six channels.
Basic JS-ICON Troubleshooting Fault/Complaint Status LED Indicators Possible Reason/Fix No output (all circuits). Power LED Off. No power to system. Check main breaker. No output (all circuits). Power LED Flashes. Microcontroller failure. Contact factory. No output (all circuits). Power LED On, RX LED Off. No DMX signal is present. No output (all circuits). Power LED On, RX LED Flashes. Invalid DMX signal is received. No output (all circuits).
Precision Demultiplexer Printed Circuit Board DMX INPUT/THRU Connection (J11) This internal DMX connection may be used alternatively to the external 5-Pin XLR connectors. It is also the location used for connection of the wireless DMX receiver option. MODE SELECT DIP SWITCHES Provides system configuration options (see page 10 for details). +5VDC and +15VDC Power Supply Output Connection (J8) This connection supplies power for external devices.
Phase Reference Printed Circuit Board 3-Phase/1-Phase Select Switch (SW1) This switch enables selection of 3-Phase or 1-Phase operation of the JSICON™ . If this switch is not in the correct position, dimmers 3 and 4 will not dim correctly and appear as though they are non-dim. Refer to 3-Phase to 1-Phase conversion directions on page 6 for more details. DC Power Supply Fuse (F1) This fuse protects the on-board switch mode DC power supply from overcurrent.
