Page 3 of 20 RA – 122 RACK MOUNT ARCHITECTURAL DIMMER OWNERS MANUAL Revision 0.93 09/26/2011 RA-122 UNIT DESCRIPTION POWER REQUIREMENTS The RA-122 consists of a 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. The RA-122 may be controllad by DMX controllers and several types of wall remote stations.

REQUIREMENTS 09/26/2011 THE UNIT WILL NOT OPERATE IN IT'S THREE PHASE CONFIGURATION USING ONLY 2 LINES OF A 3 PHASE 120/208 VAC SUPPLY CIRCUIT. CONNECTIONS Connect the 3 in hot feed lines to the 3 terminals on the input power terminal block (H1, H2, H3).

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 to the power source. The unit should be connected to two hot lines which are NOT the same phase.

The connectors are "hardwired" together so either one can be used for "in" or "out". The RA-122 is supplied with one of several different rear load connection panels.
Page 7 of 20 RA – 122 RACK MOUNT ARCHITECTURAL DIMMER OWNERS MANUAL Revision 0.93 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. 09/26/2011 Smart remote signals to the RA-122 are transmitted over a two twisted pair, shielded, low capacitance cable. One pair carries the RS-485 signal and the other provides a low voltage power and common to the remotes.

Scenes 1 - 7 (stored in the RA-122) may be accessed by simple remotes. A BLACKOUT FUNCTION may also be accessed. A simple remote is any switch which can provide a momentary contact closure that can be applied to a specific pin on the RA-122 CONTROL SIGNALS CONNECTOR (DB25 connector).

The display will show a menu so you can select an existing scene to copy from. The procedure is similar to that for other scenes except the blackout fade time is accessed by selecting SCENE 00 from the SCENE SETUP menu. Factory default fade time is 3 seconds. Blackout fade time may be set between 0.5 and 99.5 seconds.

See the section "Creating and Editing Scenes" for info about programming the scenes. These scenes are grouped according to which type of smart remote can access them. Scenes 1 - 48 are reserved for push button and IR remotes.
Page 14 of 20 RA – 122 RACK MOUNT ARCHITECTURAL DIMMER OWNERS MANUAL Revision 0.93 09/26/2011 EVENT SYSTEM OPERATION SETTING THE INTERNAL CLOCK The RA-122 includes 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 clock must be set to the correct date, time and day of the week in order to operate correctly.
