Version 1.2 Smartrack User Manual One thermal sensor is provided for each power device, and constantly feeds back temperature status information to the central processor (CPU). The CPU uses this information to decide when it is necessary to switch on the fan for any given power assembly.
3. Getting started – what’s in the box 3.1. Smartrack Smartrack systems are shipped broken down into racks and power assemblies (up to three per rack). Please check carefully to verify that you have everything you need before starting the installation.
Version 1.2 Smartrack User Manual 3.1.2 Power assemblies Power assemblies are packed individually, and are of two main types – basic or modular. Basic power assemblies come with the power devices permanently mounted on a single heatsink on the front of the assembly.
Smartrack User Manual ETC Ltd 4. Installation Smartracks are intended for mounting either against a wall, back to back in an island formation or in a flightcase. This section deals with wallmount or island installation – see the next section for information on flightcasing.
Version 1.2 Smartrack User Manual We recommend using a large cable duct running across the top of a bank of Smartracks, carrying power and load wiring. Alternatively, power wires may be run in from below, and load wires from above, or vice versa.

Smartrack User Manual 4.6. Load wiring All load wiring enters the Smartrack(s) by either the top or bottom load entry port in the large centre section of the rack. Smartrack is primarily designed for load wiring with single core cables in cableways, but may also be wired with three core or multicore cables.
4.8. Signal wiring Smartrack uses the international digital dimmer standard USITT DMX512 (1990) to receive dimmer drive signals from a controller. DMX wiring requires twisted pair and overall screen cable (Belden 9841 or equivalent), rated for RS485.
4.9.2 Connecting load wiring Carry out the following steps for each power assembly. If the wires are correctly laid in the back of the Smartrack, they should line up well with the load terminals on the face of the power assembly.

4.10 Smartrack door The door mounts on the left side of the rack, and supports all the rack electronics. Mounting the Smartrack door is the last part of the installation procedure. 4.10.1 Mounting the door Remove the door from its packaging.
Screen (ground) 4.10.4 Connecting power assembly signal looms Using the flat ribbon cable clips mounted inside the Smartrack, run the rib- bon cable from the top power assembly around the top of the rack, and terminate to the top position on the Smartrack CPU. Fold any excess cable flat inside one of the cable clips.
Fit the blanking plate(s) in position, then replace and tighten the M3 washers and nuts. Note: if Smartrack is only partially populated with power assemblies, then blanking plugs must be fitted to unused outputs of the CPU board. These are supplied with the power assembly blanking plate 2000A1500.
4.10.8 Fitting dimmer number strips Self adhesive numbering strips are provided to give smart and permanent identification of dimmer numbers on the front of the rack. Each Smartrack is provided with one sheet containing the numbers 1–240. Spare sheets and higher numbers are available from ETC, under the following part num-...
Version 1.2 Smartrack User Manual 5. Commissioning and configuration 5.1. Switching on a) For the first switch-on only, first set all MCBs and RCDs (if fitted) to the off (down) position. b) Switch on power to the rack, and check that the three yellow power supply LEDs L1, L2 and L3 are on, indicating that power from all three phases is reaching the power supply section.
DMX bad data LED (red) – indicated with a – on if DMX data is missing or corrupted, in which case it will be ignored by Smartrack. If red LED flashing, DMX signal has been lost. It is not necessary to receive DMX at this stage in the commissioning process, so, providing the system’s DMX source is not on, a red DMX indicator is fine.
5.5. Using offline mode There are two levels of access to Smartrack’s control panel, which is normally safeguarded from accidental operation. The first level is used for dimmer testing, plus changes to dimmer addressing, profiles and response speed. The second level –...
(dependent on choke type), plus an average cable loss – say 3V rms (dependent on installation), the highest voltage that can be deliv- ered to the lamp will be around 233V. But by setting the Smartrack refer- ence voltage to 227V, the dimmers will regulate to provide a constant 220V at the lamp, even though supply voltage may fluctuate at any level above 227V.
5.6. Testing dimmer circuits with the rotary potentiometer Using the rotary pot on the control panel, you can test any or all of the dimmers in a Smartrack, without requiring external dimmer drive signals (DMX). This is the next stage of commissioning: a) Check that the level pot is turned anticlockwise (off position).
In order to guarantee correct performance of DMX512, the end of the line must be terminated with a resistor. This is done in Smartrack by setting the jumper J6 to the T(erminated) position, in the last rack only in the DMX512 chain.
Smartrack, and achieve consistent fade results or safe non-dim operation. Smartrack is shipped with the factory default IES Square Law profile set for all dimmers, which results in linear light output in relation to DMX control input, for most types of filament lamps.
Smartrack User Manual ETC Ltd 5.8.2 Smartrack standard profiles Display Profile Name Characteristics IES Square Law Default setting for most lighting require- ments – provides linear light output in relation to DMX512 level for most lighting loads. ‘S’ Law Used for some early thyristor dimmers in theatre applications.
Smartrack does not regulate non-dim or hot profiles, so by setting the non- dims at the rack, a full output wave-form can be guaranteed for sensitive loads.
The response speed is the time taken for a dimmer to ramp to a new level received via DMX. Response speed is measured in milliseconds, and should not be confused with current risetime, measured in microseconds. Smartrack offers a range of four response speeds, which are appropriate for different lighting tasks.
DMX levels will be implemented gently. If power is lost while this temporary response time is being used, the next time Smartrack is switched on it will retain a 2 second response speed, and show 02 in the display window.
6.1. Accessing the control panel Smartrack's control panel is normally disabled, to prevent unauthorised access, which could have potentially disastrous results. When the enter LED is off, the control panel is disabled. To access control panel user mode: a) Press enter for three seconds.
LED is now lit. In dimmer mode, when using the keys, note that Smartrack limits the range of dimmer numbers displayed to the dimmers in the rack, plus ALL, where all dimmers in the rack may be tested, or have profile and speed settings changed.
Smartrack User Manual ETC Ltd You can flash through the rack by setting the rotary pot to a level, then using the key repeatedly, to advance to the next dimmer. When you do this, the previously used dimmer will go out, and only the currently select- ed dimmer will be set to the level on the pot.
When ‘Dim-ALL’ is selected, the profile or speed displayed is for the first dimmer only. 6.4. Offline mode Smartrack's offline mode is intended for installers and service engineers, and has a separate security level to user mode. In offline mode, all dimmer levels received via DMX512 are set temporarily to zero.
Smartrack User Manual ETC Ltd 6.4.1 Checking line voltage From the offline menu, select AC and press enter. The display alternates between L2 and the present rms voltage found on the phase two supply to the rack, eg 220. To exit, press enter. The display returns to the AC menu header, press , until the offline menu header –...
In average conditions of use, cleaning should be carried out on an annual basis. a) Using a vacuum cleaner with a soft furniture nozzle, clean the outside of the Smartrack enclosure. Then use a damp or spirit-soaked rag to remove grease or stains.
7.4. Control fuse ratings 1.6amp (T) 20mm 7.5. Battery replacement It will be necessary to replace the battery on the Smartrack CPU which supports configuration settings at approximately ten year intervals. This work should be carried out by an authorised ETC service representative.
Smartrack User Manual 8. Technical support In the event of difficulty during the installation, commissioning or active life of your ETC dimming products, technical support is available at no charge, either from your ETC authorised service agent, or from ETC direct.
Many local authorities and safety conscious employers are now insisting that earth leakage protection be fitted to all professional lighting dimming systems. When ordering Smartrack, you can specify Residual Current Device (RCD) pro- tection as a factory fitted item. If not supplied as original equipment, RCDs may be easily retrofitted to Smartracks in service.
