AR-1202 UNIT DESCRIPTION |
POWER REQUIREMENTS |
|
|||||||
The AR-1202 consists of an embedded micro processor and 12 dimmer channels of 2.4KW each. Each dimmer channel is protected by a 20 Amp circuit breaker. Heavy duty filtering chokes are used to reduce noise. Dimmer channel semiconductors exceed a 200% load carrying capacity overhead allowance. All components and sub systems are UL recognized components. All internal wiring conforms to UL standards as they apply to industrial controls. Dimensions and weight information is given at the end of this manual.
EXTERNAL CONTROLS
The AR-1202 can communicate with remotely located control equipment in several ways.
A USITT DMX-512 protocol bus is provided so the unit may be used with any DMX lighting console. The AR-1202 is fully patchable with respect to the DMX bus.
The AR-1202 may also be controlled by several types of wall mounted smart remote stations. Smart remotes communicate with the AR-1202 by way of a low voltage RS-485 bus. This bus is completely separate from the DMX bus. Smart remotes are used to activate preset scenes which have been stored in the AR-1202. There are several types of smart remote stations. Multiple smart remotes of the same or different types may be chained together on the RS-485 bus. The same RS-485 bus may be chained to multiple AR-1202 dimmer packs.
The AR-1202 may additionally be controlled by an arrangement of one or more momentary switches (simple remotes). The switches may be used to control a specific set of scenes stored in the AR-1202.
REAL TIME CLOCK EVENT SYSTEM
The AR-1202 contains an internal clock and timer sub system. This subsystem may be used to create events which activate and switch between preset lighting scenes based upon times, days, and dates. A total of 128 events may be programmed.
The AR-1202 may be operated from 50/60 Hz, 120/208 VAC, three phase power or from 50/60 Hz, 120/240 VAC, single phase power. Input power to the unit must be capable of delivering 80 Amps per line if using three phase or 120 Amps per line if using single phase power.
The AR-1202 can operate using only 2 phases of a 3 phase power source. This is NOT RECOMMENDED since it causes an unbalanced load at the power feed source.
The AR-1202 is must be used with a WYE connected power source. A NEUTRAL line is required.
INSTALLATION
PHYSICAL LOCATION
The unit is intended for INDOOR OPERATION ONLY and should not be subjected to excessive moisture or heat. The unit should be installed where a supply of circulating air is available. The AR-1202 is designed to be wall mounted in a equipment room or electrical distrubution area. The ambient air in the installation area should be below 86 deg F.
The AR-1202 is convection cooled by heatsinks on the left and right sides of the unit. Provide spacing between the unit and other equipment to allow air flow around the unit (particularly around the finned heat sinks). See “Dimensions and Locations” in this manual for more information concerning mounting of the unit.
POWER INPUT CONNECTIONS
WARNING
MAKE CERTAIN POWER IS REMOVED
FROM THE FEED CIRCUITS
BEFORE YOU BEGIN INSTALLATION.
Consult applicable electrical codes to determine the proper wire type and methods.
The AR-1202 operates using either 3 phase 120/208 VAC or single phase 120/240 VAC power. The unit is shipped from the factory as a THREE PHASE unit. It can be field converted to single phase unit.

THREE PHASE POWER CONNECTIONS
CONNECTIONS
WARNING
MAKE CERTAIN POWER IS REMOVED
FROM THE FEED CIRCUITS
BEFORE YOU BEGIN INSTALLATION.
REQUIREMENTS
Actual 120/208VAC three phase power must be supplied to operate the AR-1202 in the 3 phase configuration. This means that the voltage across any two lines must be 208 VAC. The feed circuit must be able to supply 80 Amps for each hot line.
THE AR-1202 WILL NOT OPERATE IN A THREE PHASE CONFIGURATION FROM 2 LINES OF EITHER A SINGLE OR 3 PHASE SUPPLY CIRCUIT.
Connect the 3 in hot feed lines to the 3 terminals on the input power terminal block (H1, H2, H3).
Connect the feed neutral to the NEUTRAL bus bar.
Connect the feed ground to the GROUND lug.
HIGH VOLTAGE CIRCUITRY IS EXPOSED WHEN THE CABINET DOOR IS OPEN. DO NOT ALLOW THE UNIT TO OPERATE OR HAVE POWER APPLIED TO IT WHILE THE DOOR IS OPEN.
See the section SYSTEM POWER SETUP for operation using 3 phase connections.

SINGLE PHASE POWER CONNECTIONS
WARNING
MAKE CERTAIN POWER IS REMOVED
FROM THE FEED CIRCUITS
BEFORE YOU BEGIN INSTALLATION.
REQUIREMENTS
The RA-122 can operate as a single phase unit using using only 2 phases of a 3 phase power source. This is NOT RECOMMENDED since it causes an unbalanced load at the power source.
The feed circuit must be able to supply 120 Amps for each line.
CONNECTIONS
There are three terminals on the input power terminal block (H1, H2, H3). When operating the AR-1202 on single phase power, the center (H2) terminal is not used.
The wires connected to the left side of the H2 terminal contain color coded sleeves (RED and BLUE). These wires must be moved and distributed to the H1 and H3 terminals. Remove the wires from the H2 terminal and connect them to H1 and H3 such that the sleeve color matches the wire colors on H1 and H3.
Connect the feed neutral to the NEUTRAL bus bar.
Connect the feed ground to the GROUND lug.
HIGH VOLTAGE CIRCUITRY IS EXPOSED WHEN THE CABINET DOOR IS OPEN. DO NOT ALLOW THE UNIT TO OPERATE OR HAVE POWER APPLIED TO IT WHILE THE DOOR IS OPEN.

LIGHTING LOAD CONNECTIONS
Lighting to be controlled by the AR-1202 must be connected to the terminal strip located on the front of the lower seperator panel of the cabinet. The lowest number dimmer channel output connection is on the left. See the EXTERNAL CONNECTIONS DIAGRAM. Above. The load connections terminal strip is shown as CHANNEL OUTPUT CONNECTIONS in the diagram.
CONTROL SIGNAL CONNECTIONS
Terminal strips are provided for connection to DMX consoles, smart remotes, and simple remote stations. Specific wiring connection point information for all external control signals is shown in the EXTERNAL CONNECTIONS diagram above.

DMX CONSOLE CONNECTIONS
DMX console signals to the AR-1202 should be transmitted over a twisted pair, shielded, low capacitance cable. A DMX console transmits from a female, 5 Pin XLR Connector.
See the EXTERNAL CONNECTIONS and the example below for specific connection information.
DMX TERMINATION
A DMX bus should be terminated (only) at the last receiving device on the chain. This is done by connecting a 120 ohm, 1/4 watt resistor across the DMX DATA - and DMX DATA + lines.
A DMX bus should be daisy chained to all its receiving units. It should NOT be connected in a star arrangement with multiple "home runs".
CAUTION
REMOVE ALL POWER FROM THE AR-1202 BEFORE MAKING OR CHANGING DMX CONSOLE CONNECTIONS.
