LIGHTRONICS AR1202RTC Architectural Lighting Control Wall Mount Dimmer Owner’s Manual

LIGHTRONICS AR1202RTC Architectural Lighting Control Wall Mount Dimmer

AR1202RTC UNIT DESCRIPTION
The AR1202RTC is a FORWARD PHASE/LEADING EDGE dimmer that consists of an embedded micro-processor. The AR1202RTC has 12 channels of 2.4KW each. The AR1202-6RTC has 6 channels of 2.4KW each. Each dimmer channel is protected by a 20 amp circuit breaker. Heavy duty filtering chokes are used to reduce filament noise. Dimmer channel SCRs exceed a 200% load carrying capacity overhead allowance. The AR1202RTC conforms to UL standards as they apply to industrial control equipment. Product specifications are provided at the end of this manual. The AR1202RTC & AR1202-6RTC will simply be referred to as AR1202 and AR1202-6 in this manual unless there are differences in the models.

EXTERNAL CONTROLS
The AR1202 can communicate with remotely located control equipment in several ways. A USITT DMX512 protocol bus is provided so the unit may be used with any DMX lighting controller. The AR1202 is fully patchable with respect to the DMX bus. The AR1202 may also be controlled by several types of wall mounted smart remote stations. Smart remotes communicate with the AR1202 over LitNet. This is a Lightronics proprietary 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 AR1202. There are several types of smart remote stations. Multiple smart remotes of the same or different types may be daisy chained together. Multiple AR/AB/RA model dimmers and architectural controllers may also be daisy chained together on LitNet. The AR1202 may additionally be controlled by an arrangement of one or more momentary contacts (simple remotes). These contacts may be used to control a specific set of scenes stored in the AR1202. The AR1202 follows a ‘Last Takes Precedence’ hierarchy between DMX and remote operation.

REAL TIME CLOCK EVENT SYSTEM
The AR1202 contains an internal clock and timer subsystem. 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.

POWER REQUIREMENTS
The AR1202 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 power or 120 amps per line if using single phase power. The AR1202-6 input source must be capable of delivering 40 amps per line if using three phase power or 60 amps per line if using single phase power. The AR1202 can operate using only two phases of a three phase power source. However, this is NOT RECOMMENDED, since it causes an unbalanced load at the power feed source. When using three phase power, the AR1202 must be used with a WYE connection power source. A NEUTRAL line and a separate GROUND line are 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 AR1202 is designed to be wall mounted in an equipment room or electrical distribution area. The ambient air in the installation area should be below 86° F. The AR1202 dimming components are cooled by heatsinks on the sides of the unit. These are only on the left side of the AR1202-6. Additional cooling is provided by vents in the front, top and bottom of the AR1202. Provide spacing between the AR1202 and other equipment to allow air flow around the unit (particularly around the finned heat sinks). See “Dimensions and Mounting” 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 electric al codes to determine the proper wire type and methods. The AR1202 operates using either three 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 a single phase unit. THREE PHASE POWER 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 AR1202 in the three 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 of the AR1202 (40 amps for each hot line of the AR1202-6).

THE AR1202 WILL NOT OPERATE IN A THREE PHASE CONFIGURATION FROM TWO LINES OF EITHER A SINGLE OR THREE PHASE SUPPLY CIRCUIT. SEE THE SINGLE PHASE POWER CONNECTIONS FOR INSTRUCTIONS.

CONNECTIONS

• Connect the feed ground to the GROUND lug.
• Connect the feed neutral to the NEUTRAL bus bar.
• Connect the three hot feed lines to the three terminals on the input power terminal block (H1, H2, H3).
• 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.

THREE PHASE POWER CONNECTIONS

WARNING
MAKE CERTAIN POWER IS REMOVED FROM THE FEED CIRCUITS BEFORE YOU BEGIN INSTALLATION.

REQUIREMENTS
The single phase 120V feed circuits must be able to supply 120 amps for each line for the AR1202 (60 amps for each line for the AR1202-6). These wiring instructions are also applicable if the only available feed circuits are two legs of three phase power. This is NOT RECOMMENDED since it causes an unbalanced load at the power source.

CONNECTIONS
There are three terminals on the input power terminal block (H1, H2, H3). When operating the AR1202 on single phase power, the center (H2) terminal is not used. Connect the feed ground to the GROUND lug. Connect the feed neutral to the NEUTRAL bus bar. The wires connected to the right side of the H2 terminal contain color coded sleeves (RED and BLACK). 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. 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.

SINGLE PHASE POWER CONNECTIONS

EXTERNAL CONNECTIONS

LIGHTING LOAD CONNECTIONS
Lighting to be controlled by the AR1202 must be connected to the terminal strip located on the front of the lower separator 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 controllers, 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 CONTROLLER CONNECTIONS

DMX controller signals to the AR1202 should be transmitted over a shielded, twisted pair, low capacitance cable. Most DMX controllers transmit 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 configuration with multiple separate runs without an approved DMX optically isolated splitter.

CAUTION
REMOVE ALL POWER FROM THE AR1202 BEFORE MAKING OR CHANGING DMX CONTROLLER CONNECTIONS.

DMX CONNECTIONS EXAMPLE

SMART REMOTE CONNECTIONS (LitNet)

There are two types of smart remotes (push button and fader) which can be used with the AR1202. There are multiple models of each type. They all connect to LitNet, which is a proprietary RS-485 bus that can be controlled by an AR1202. Additional AR/AB/RA dimmers may also be connected on the same bus and each can serve as a LitNet host. One of them will be set as the master host controller by making UNIT ADDRESS ASSIGNMENTS. Smart remote signals to the AR1202 are transmitted over a shielded, two twisted pair, low capacitance cable. One pair carries the RS-485 signal and the other provides low voltage power and common to the remotes. The LitNet bus should be daisy chained to all of its receiving units. It should NOT be connected in a star configuration with multiple separate runs.Each smart remote has a 4-pin connector with screw down terminals to connect to the LitNet bus. You must get the correct wiring pinout information for each remote unit from its respective owner’s manual.

CAUTION
REMOVE ALL POWER FROM THE AR1202 BEFORE MAKING OR CHANGING SMART REMOTE CONNECTIONS. See the diagram “EXTERNAL CONNECTIONS” and the example below for specific connection information. SMART REMOTES CABLE CONDUCTOR ARRANGEMENT FOR DUAL TWISTED PAIR, SHIELDED CABLE

SMART REMOTE (LitNet) CONNECTIONS EXAMPLE

SIMPLE REMOTE CONNECTIONS

CAUTION
REMOVE ALL POWER FROM THE AR1202 BEFORE MAKING OR CHANGING SIMPLE REMOTE CONNECTIONS. Scenes 1 – 7 (stored in the AR1202) 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 which can be applied to a specific pin on the AR1202 SIMPLE REMOTE CONNECTIONS terminal strip. The SIMPLE REMOTE COMMON is routed to the remote switch. When the switch is operated, the closure brings the common back to the applicable simple remote scene number connection point at the AR1202 terminal strip. Almost any available low voltage wire may be used since these connections are just contact closures. Multiple simple remotes may be used. Additionally, multiple AR1202 units may be chained to one or more simple remotes. See the diagram “EXTERNAL CONNECTIONS” and the example below for specific connection information.

AR1202 UNIT SETUP

• Legacy units will have rectangular push-buttons rather than square push-buttons and may require a previous version of this manual.

AR1202 UNIT SETUP

The AR1202 must be set up (configured) as part of the installation process. This process is done from the AR1202 front panel using five menus described below. SYSTEM SETUP should be done first. It includes setting the System Mode, System ID, and System Power Setup. DIMMER SETUP should be done next. It includes Channel Limiting and Dim/Non-Dim selections. DMX I/O SETUP must be performed if the unit will be used with a DMX controller. This setup assigns (patches) dimmer channels to DMX addresses and can lockout the wall remote stations. SCENE SETUP must be performed to create scene presets to be activated from the remote control stations or by the clock/timer subsystem. EVENT SETUP must be done if the clock/timer subsystem will be used. It includes Setting the Clock and Programming Events.

TOP LEVEL MENUS LAYOUT

USING THE MENU SYSTEM
The MENU (NEXT) button steps through the five display menus. When one of these menus is displayed you can push the ENTER button to access that function. The CLEAR button will return the unit to its normal operating mode and cause the display to show the channel level bar graph. The CLEAR button DOES NOT clear entered values. The arrow buttons are used to set values for menu selections.

There are two additional settings which are used only when it is not possible to provide actual 120/240V Single Phase power and the unit is being powered by two phases of a 120/208V Three Phase source.

• AR 2PhsN: Two Phase 120/208V Power Source Normal Phase Rotation
• AR 2PhsR: Two Phase 120/208V Power Source Reverse Phase Rotation

NOTE: There are other settings available in this menu. These do not apply to the AR1202 dimmer. You may not know in advance if you should use the Normal or Reverse rotation choice for Three Phase or Two Phase power. If this is the case then use NORMAL phase rotation initially. NO damage will occur if the rotation is reversed, but dimming will not occur properly and some channels will appear to be in an on/off mode. This will be apparent when operating the unit. You can then change the setting.

UNIT ADDRESS ASSIGNMENT
When using a single AR1202 system, the unit address MUST BE SET TO 00. One (and only one) of the units in a multiple unit system must be set to address 00. Other units should be assigned in sequential order. This is required for proper smart remote operation.

• Push ENTER. Then push MENU (NEXT). The System ID Set menu will be shown.
• Push ENTER. The display shows the unit address.

Set the desired address by using the ↑ and ↓ buttons. Push ENTER. Then push CLEAR to return to the normal operating mode.

DIMMER CHANNEL SETUP
Individual channels within the AR1202 dimmer can be set for different behaviors. Any channel may be limited to a user selected maximum intensity level. Limiting applies to manual, scene, and DMX operation. Any channel may also be set to run as NON-DIM to act simply in an on/off manner.

CHANNEL LIMITING

• At the AR1202 front panel – push MENU (NEXT) until the Dimmer Setup menu appears on the display.
• Push ENTER. The Channel Limit menu will be shown.

Use the ← and → buttons to select a channel. Then use the ↑ and ↓ buttons to set its limiting DMX value. Push ENTER when finished. The DMX limit range on the menu is between 10 and 255 which corresponds roughly to lighting intensity in between 4% and 100%.

CHANNEL DIMMER/NON-DIM MODE
Each channel can be operated in either a DIMMER mode or a NON-DIM mode. The NON-DIM mode still uses the SCRs in the AR1202 to control power, but operates in more of an on/off manner. Other options are found in this menu but are not widely used.
Push MENU (NEXT) until the Dimmer Setup menu appears on the display.

• Push ENTER. Then push MENU (NEXT). The display will show the menu:

Use the ← and → buttons to select a channel. Then use the ↑ and ↓ buttons to switch between DIMMER and NON-DIM. Push ENTER when finished.

DMX I/O SETUP
DMX I/O Setup consists of two functions, Dimmer channel assignment and Smart Remote lockout.

DIMMER CHANNEL ASSIGNMENT

• Dimmer channel assignment is used to assign individual AR1202 channels (circuits) to a DMX address. Each dimmer channel (1 – 12) can be patched to any of 512 DMX addresses. At the AR1202 front panel – push MENU (NEXT) until the DMX I/O Setup menu appears on the display.
• Push ENTER. The display shows AR1202 dimmer channels on the top line. The currently assigned DMX address is shown on the lower line prefixed by “DMX”.

Use the ← and → buttons to select a dimmer channel. Then use the ↑ and ↓ buttons to assign it to a DMX address. Push ENTER after each channel assignment. Push CLEAR to exit from the menu. It will not clear your settings.

DMX LOCKOUT
You can set any dimmer channel output to ignore DMX signal inputs from a DMX controller by assigning it to DMX address 000. This feature can be used with house lights or other special lighting. The channel will still respond to smart and simple wall remotes but the DMX input signal will be ignored.

SMART REMOTE LOCKOUT
The Smart Remote Lockout function prevents the AR1202 from responding to the smart remote wall stations when a DMX signal is present. Simple remote stations will still function.

NOTE: When feature is active, any active scenes will be turned off once DMX is applied.

• At the AR1202 front panel – push MENU (NEXT) until the DMX I/O Setup menu appears on the display.
• Push ENTER. Then push MENU (NEXT). The display will show the lockout menu.
• Use the ↑ and ↓ buttons to select Yes or No. Push ENTER when the desired state is shown.

CREATING AND EDITING SCENES

• At the AR1202 front panel – push MENU (NEXT) until the Scene Setup menu appears on the display.

• Push ENTER. The display shows the current scene number.

Use the ← and → buttons to select the scene you want to set up and push ENTER. Scene 000 controls blackout fade time. Scene 001 is the first user scene.

There are three ways to create or set up a scene:

1. Set each channel intensity manually (EDIT SCENE).
2. Copy another existing scene (COPY SCENE). You can then edit the results.
3. Record a snapshot of the current channel intensities (RECORD LIVE NOW).

Push MENU (NEXT) to select one of the three methods described above. The display will show the corresponding menu.

TO CREATE A SCENE MANUALLY
Push ENTER when EDIT SCENE is shown. The current dimmer channel number is shown on the display upper left. The current scene number (which was selected in the previous step) is shown on the display upper right. The settings for three dimmer channels are shown on the lower display row.The LEFT channel on the display is the current dimmer channel (the channel which you will set the intensity level for).

Use the ↑ and ↓ buttons to set the channel output intensity. The display shows the intensity setting as a number between 0% and 99%. A 100% setting is indicated by “FL”. A “XX” setting means that the channel will be ignored for the current scene. This is useful when stacking of scenes is desired. Push ENTER after each channel level is set. Use the ← and → buttons to proceed to the next channel to be set up. The lower row of the display will shift to the left. Repeat the channel intensity selection for that channel. Push CLEAR when all the channels for the selected scene are set. This will not clear your scene settings. To setup another scene – repeat the process above using a different scene selection.

TO COPY A SCENE
Push ENTER when COPY SCENE is shown. The display will show a menu so you can select an existing scene to copy from.

Use the ← and → buttons to select a scene. Then push ENTER. The scene will be copied and you will be transferred to the EDIT SCENE menu where you can further adjust the scene settings if desired.

TO RECORD A LIVE SCENE
A scene may be created by recording the current channel intensity levels. Push ENTER when RECORD LIVE NOW is shown. You will be transferred to the EDIT SCENE menu with the current settings. You can adjust these settings as shown above. Push ENTER to record the scene at these values.

SCENE FADE TIME
A fade time may be set individually for each scene. This is the time elapsed between a scene fully active and the next scene fully active. The factory default fade time is 3 seconds. Fade time may be set between .5 and 99.5 seconds and is set from the SCENE SETUP menu (usually as you set channel intensities for the scene).

1. To set a scene fade time – Access the EDIT SCENE menu for the desired scene.
2. Use the ← and → buttons to move BEYOND the last channel (CHANNEL 16) for the scene. The display will indicate the current fade time for the scene.
3. Use the ↑ and ↓ buttons to set the desired fade time. Then push ENTER.
4. Push CLEAR to select another scene for fade time set up.

SCENE BLACKOUT FADE TIME
Fade time for the remote stations blackout function is set as an independent function. 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. To select a fade time – use the ← and → buttons. Push ENTER when the desired time is shown.

OPERATION

MANUAL OPERATION
Individual dimmer channels may be operated from the AR1202 front panel. This is useful during testing and setup operations. Use the ← and → buttons to select a channel. The associated channel on the bar graph display will flash. Use the ↑ and ↓ buttons to set the lighting intensity for the selected channel. Manual operation combines with DMX and remote stations settings but does not lock them out. The CLEAR button will turn off all channels when operating manually.

DMX CONTROLLER OPERATION
If a DMX signal is present when the AR1202 is turned on, it will automatically respond to it. A “D” will be shown in the lower right corner of the LCD display if a valid DMX signal is present. Channel intensity levels will be shown on the bar graph display.

SMART REMOTES OPERATION (LitNet)
The AR1202 can store 100 preset scenes which may be activated by smart remotes. See the section “Creating and Editing Scenes” for information 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. Scenes 51 – 99 are used with fader remotes. If multiple LitNet host units are connected to a smart remote, then each LitNet host will activate its own corresponding scene. For a single dimmer system, when activity on the smart remote bus is sensed by the AR1202, an ‘R’ will be displayed on the screen. If multiple dimmers are connected together, the AR1202 assigned to Unit ID 00 will indicate ‘R’ only when there is activity from a smart remote station. AR1202 dimmers with a Unit ID of 01 or higher show an ‘R’ continuously as long as they have communication with the Unit ID 00 dimmer. Both, push button and fader remotes may be connected to the same smart remote bus.

BUTTON AND IR SMART REMOTES OPERATION
These remotes activate individual scenes within a block of scenes which have been stored in the AR1202. Generally, users only have one scene on at a time. However, scenes can be stacked with the use of ‘XX’ as a setting for channels of each scene that will have a value assigned in other scenes being used together. The remotes are set to specific blocks of scenes to be activated by the remote. You can select which block of scenes will be activated by the remote when ordering the remote or by contacting Lightronics technical support to reprogram. For instance, an AC1109 can be set to control scenes 1-8, 9-16, or other blocks of eight consecutive scenes. There are a total of six scene blocks available covering scenes 1 thru 48. Multiple remotes may be, but are not required to be, set to the same block of scenes. The scene activation buttons will toggle. In other words, a scene will go OFF if you push its button while the scene is active. The OFF button invokes a BLACKOUT for all scenes associated with that remote’s scene block ID. Refer to the smart remote manual for specific information on scene addressing.

FADER SMART REMOTES OPERATION
These remotes activate specific individual scenes which have been stored in the AR1202 on a “pile on” basis. In other words, multiple scenes will merge together in a “greatest of” fashion. This means the intensity of any given channel will go to the highest level of all the scenes which use it. If multiple fader stations are in use in a system, the AR1202 will follow a last takes precedence protocol for common scenes between fader stations. Fader remotes are scene block addressable so you can select which scenes it activates. There are three scene blocks available. Each block includes 16 scenes. The first block starts at scene 51. This refers to the lowest numbered fader on the remote. The other faders on that remote will use the next consecutively numbered scenes (52, 53, 54, etc.). The second and third scene blocks begin at scene 67 and 83 respectively. Multiple remotes of this type may be, but are not required to be, set to the same block of scenes. The OFF button invokes a BLACKOUT for all scenes associated with that remote’s scene block ID. Refer to the fader smart remote owner manual for specific information on setting scene blocks.

SIMPLE REMOTES OPERATION
Scenes 1 – 7 (stored in the AR1202) 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 AR1202  SIMPLE REMOTE UNIT INPUTS terminal strip. Lightronics currently offers an APP01 simple remote. The APP01 is a “center off, single pole, double throw, momentary contact, toggle switch.” It can be used as a simple entrance switch to activate a scene when someone enters/exits an area. Alternative devices such as relays, timers, and motion sensors can be connected to AR1202 dimmers as simple remotes. These are available from a variety of manufacturers. The momentary completion of a circuit path between the simple common terminal and one of the scene terminals will activate the respective scene.

EVENT SYSTEM OPERATION

The AR1202 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 will still operate without AC power for approximately two weeks and does not require a battery. Event settings are retained in non- volatile memory; therefore, they will not be lost if the AR1202 is powered off. An event is used to trigger any one of 100 scenes which have been previously created and stored in the AR1202. Any scene may be used by multiple events. A scene may be set to turn ON, turn OFF, or be ignored by an event. An event may be set to trigger based on a date of the year and a time. This enables scene activation for one time or infrequent occurrences such as holidays. An event may also be set to trigger on a daily or multiple times per day basis. Additionally, specific days of a week can be designated to be used or skipped. This is a more common type of operation where events are triggered on a regular schedule.

EVENT SYSTEM ENABLE
Events programmed in the AR1202 will not trigger unless the event system is set to ON. If the event system is OFF you can still set the clock and program event times and dates but they will never be triggered. Setting events to OFF is used to prevent inadvertent triggers which may have been forgotten about, incorrectly set, or when events are no longer required.

TO CONTROL EVENT TRIGGERING
Push ENTER from the Event Setup menu. The display will show the event system ON/OFF menu.

Use the ↑ and ↓ button to select ON or OFF. Push ENTER when the desired ON/OFF state is shown.

MAKE CERTAIN POWER IS REMOVED FROM THE FEED CIRCUITS BEFORE HANDLING THE UNIT.

The AR1202 has a 1/2 amp, 250V, Type ABC, fast acting fuse on the inside of the cabinet. It provides protection only for the internal electronic control circuitry. It may be replaced ONLY by a fuse of identical type and size. Contact a qualified electrical maintenance person if you suspect this fuse has blown. 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. The best way to prolong the life of your unit is to keep it cool, clean, and dry. It is important that the cooling intake and exit vent holes are clean and unobstructed. Service by other than Lightronics authorized agents may void your warranty.
