Introduction 1

Revision 1.0 - 7-May-02 HUB24 Series Dimmer Operating Manual

1 Introduction

The JANDS HUB24 is a unique combination of dimmer channels, power distribution and isolated DMX splitting, all in one compact and low noise package. The HUB24 is specifically designed for demanding touring and theatre applications and is ideal for shows where a mixture of conventional and automated lights are used.

Especially suitable for live shows, school auditoriums, trade shows and other similar applications, the HUB24 eliminates the usual clutter associated with dimmer racks, power distribution boxes and DMX splitters. The HUB24 also includes the ability to record and playback snapshots and chases without a lighting console.

One HUB24 incorporates:

– 15 Dimmer outputs – 9 Power Distribution outputs – 1 in 2 out opto-isolated DMX splitter

HUB24 dimmers use a chokeless IGBT output topology for reduced weight and low acoustic noise. The unit is primarily cooled by natural convection; small fans will turn on only in extreme circumstances.

The unit monitors the supply current drawn on each phase. If more than a preset limit is drawn from a phase, all the dimmer outputs on that phase are dimmed down until the current is near to the limit. This ensures connector and upstream circuit breaker current ratings are not exceeded for long periods of time.

The HUB24 features microprocessor-based digital control. A menu-driven user interface, consisting of only two buttons, an encoder wheel and a large graphics LCD, enables the user to easily monitor and select all the built-in functions.

The user has the ability to soft patch the channels out of sequence, test selected channels while the remainder of the dimmer stays on-line, download custom dimming curves, capture or build up to eight non-volatile snapshots and chases.

Other functions provided are dimmer “soft” start, bad (soft) neutral detection, monitoring supply voltage, current and other working parameters of the unit.

Control signal connection to the HUB24 is via a standard DMX-512 socket located on the front panel along with DMX through and two opto-isolated DMX outputs. Also located on the front panel are the dimmer and distribution output sockets. The three phase power entry and a cable tray are located on the rear panel.

The unit will “wake-up” in the mode it was last programmed to run - an ideal function for stand alone applications. If no particular mode has been previously defined, the unit looks for DMX control. The user has the ability to set how the HUB24 will respond if DMX control is lost, but in all cases the dimmer outputs will turn off if the DMX signal is not restored within 10 minutes.

The HUB24 range of dimmers have been designed to receive future optional software upgrades to the operating system, without opening the unit.

The HUB24 is convenient to transport due to its solid carry handles, protective transportation bag and built-in cable tray for storage of the three phase cable.

An optional wall bracket allows the HUB24 to be wall-mounted and optional hand-rail mounting brackets allow the HUB24 to be mounted on a catwalk rail.

4 Getting Started

Operating Manual HUB24 Series Dimmer

3 Getting Started

3.1 Positioning the Unit

Correct positioning and adequate ventilation are essential for reliable operation. Ensure the transportation bag or road case is totally removed before use. The HUB24 must be upright when in use, with clearances of 100mm behind, 200mm above and 100mm on each side. The unit’s feet provide air intakes (front, back & 2 sides), these openings must not be obstructed.

See section 6.2 for wall mounting details. See your Jands distributor for other mounting options.

3.2 Connecting power

The three phase cable must be completely removed from the cable tray before applying power to the unit.

The mains supply to the HUB24 dimmers must be protected by upstream circuit breakers or fuses (see sections 8.2.3 & 8.2.4). If the supply cable is damaged, it must be replaced with a cable available from JANDS or its service agents.

The power plug must be connected to an appropriately rated socket outlet. The plug’s retaining lock ring (if present) must be screwed home.

WARNING

DAMAGE MAY OCCUR IF THE RETAINING LOCK RING IS NOT

PROPERLY SECURED.

Ensure adequate mains socket access once the dimmer is installed, to allow for switching the HUB24 on and off.

Turn on the power and check that the three PHASE indicator LEDs are on. Check the large display is on and not showing any faults before connecting any loads. If the PHASE LEDs or the display indicate a fault condition, power down and remedy the fault before trying again. See section 5.5 regarding phase faults.

3.3 Set DMX start channel

The HUB24’s dimmer outputs respond to 15 DMX channels. The first channel can be set anywhere from channel 1 to channel 512, the remaining channels will follow in sequence.

• At the main screen (see section 4.1) press the large button 3 times (to select

Menu1 DMX Settings1-1 Start Channel ).

• Turn the encoder wheel to change the displayed DMX channel.

• Press the large button (now shown as OK) to save the new start channel.

See section 4.2.2 if the dimmer outputs need to respond to out of sequence DMX channels.

Getting Started 5

Revision 1.0 - 7-May-02 HUB24 Series Dimmer Operating Manual

3.4 Connecting loads

Power down the HUB24. Plug in the loads to the Dimmer output sockets. It is recommended that, where practical,

the load on the dimmer outputs be evenly spread across the 15 channels. This will minimise fan noise and make it harder to overload a single phase.

Ensure the load on each dimmer output is greater than the minimum (see section 5.7). Plug in the loads to the Distribution output sockets. Each output must not be loaded

beyond the capacity of its socket.

3.5 Connecting DMX-512

The dimmer input signal should conform to the USITT DMX-512 (1990) specification. See section 8.1 for connector wiring details.

The status of the DMX signal is indicated on the bottom of the display. The DMX input to the HUB24 dimmers connects to the IN socket on the front panel.

The DMX signal may be daisy-chained to the next dimmer via the THRU socket. If the THRU socket is not being used see section 4.2.3 for how to terminate the DMX segment.

The two ISO sockets may be used to start two new fully isolated DMX segments, which may be required for:

• Isolating DMX segments that run to equipment that is powered from different supplies.

• Star DMX network topology.

• Amplifying the DMX signal for extremely long cable runs.

• Driving more than the normal maximum of 32 devices from a console.

3.6 Power-up sequence

When powering up, the following sequence should be used:

1. Power up the control desk.

2. Power up any softpatches and/or DMX receivers.

3. Ensure the dimmer RCDs and circuit breakers are switched on.

4. Power up the dimmers last, preferably one at a time starting from the first

dimmer rack in the DMX loop.

This procedure minimises the risk of lamps and fixtures responding to any false DMX data produced by control desks or ancillary equipment at turn-on (producing the lighting equivalent of an audio “thump”) and prevents damage to lamps, dimmers, and other controlled devices.

Use the reverse procedure when powering down.

4-5 Fault Detect

The HUB24 will detect voltage problems generated by a poor or missing neutral connection. Normally when a fault is detected, all the dimmer outputs are turned off and a “Neutral Earth Fault” warning is displayed, until the fault is removed and a button pressed. See section 5.1.4 for more detail.

In some venues the three phase power supply may be less than ideal, with a “Neutral Earth Fault” warning occurring without the wiring being truly “faulty”. For this reason it is possible (but not recommended) to disable the neutral earth fault detection. ALWAYS check first that the problem is not a dropped neutral in either the three phase socket or plug and ensure the earth connection is good.

WARNING

IF THE NEUTRAL EARTH FAULT DETECTION IS DISABLED,

UNSAFE MAINS SUPPLY WIRING MAY NOT TO BE DETECTED.

Re-enable the neutral earth fault detection before the HUB24 changes venues.

4.4 Download from PC

New operating software, new dimming curves and custom logos can all be downloaded to the HUB24 from a PC. This is done without opening the unit, via the front panel DMX input connector. The following items are required:

• HUB24 dimmer

• PC Download cable

• Jands Dimmer Utility software

• IBM compatible laptop or desktop computer (with Windows95 or later)

The “HUB Download Kit” can be purchased as an accessory; it contains a PC Download cable and the Dimmer Utility software on floppy disk. Alternatively a PC Download cable can be constructed from the diagram in Appendix B and the Dimmer Utility software can be download from the Jands web site: www.jands.com.au

The following procedure assumes the “Jands Dimmer Utility” software is installed on the PC. See Appendix A for instructions on installing and using this software.

To download new software, a dimming curve or a logo to the HUB, perform the following:

1. Switch the power off to the HUB24, at the three phase outlet.

2. Connect the PC Download cable between the computer serial/COM port and the DMX input of the dimmer. Disconnect any DMX terminators.

3. Start the “Jands Dimmer Utility” software on the PC and prepare to download.

4. Press and hold the CANCEL button while turning on power to the HUB24. “Dimmer boot ROM x:xx” will be displayed with a menu.

5. Ensure “Burn Flash” is highlighted and press the large button.

6. Press the large button again to confirm flash burn.

“Start download on PC” will be displayed.

7. On the PC start downloading new software, a curve or a logo. A progress bar will be shown on the PC and “Receiving data” will be displayed on the dimmer. A software download may take up to 2 minutes to complete.

8. When complete, the dimmer checks to see if the new data is valid. If an error is displayed switch the dimmer off and start the procedure again.

9. If there are no errors the menu will be displayed. Turn the encoder wheel to highlight “Main Program” and press the large button to restart the dimmer.

Updating the operating software should be done with the following notes and cautions:

• The dimmer must be Calibrated (refer to sections 4.2.20 and 4.2.21) after downloading new operating software.

• It is recommended that dimmer software not be updated during a tour/show season, unless the currently installed software proves unsatisfactory for normal operation.

• More than one dimmer may be updated at a time using normal DMX cables to link the DMX Thru connector of the first dimmer to the input of the next, etc. In this case steps 4, 5 & 6 must be repeated for each dimmer, before proceeding to step 7.

5.1 Protection

The HUB24 series dimmers feature several types of protection. These can be generally classified as:

• RCD protection

• Output protection

• Thermal protection

• Neutral to Earth Overvoltage protection

5.1.1 RCD protection

The HUB24 protects against earth current faults with two Residual Current Detectors (RCDs). These disconnect all three phases when a very small fault current is detected. Both RCDs should be tested regularly by pressing the test buttons.

The left hand RCD protects the dimmer outputs and right hand RCD protects the power distribution outputs.

Note: The test button will not trip the RCD if the HUB is powered from a single

phase supply.

5.1.2 Output protection

Each of the dimmer circuits are protected by a fast-acting thermal magnetic circuit breaker. These breakers are designed to pass the rated current, but will disconnect the output circuit for any overload condition (the larger the overload, the quicker the disconnection).

There are 3 power distribution circuits, with 3 sockets on each circuit. Each circuit is protected by a fast-acting thermal magnetic circuit breaker.

The breakers protect the dimmer’s output devices from short-circuit loads and faulty wiring looms, and save on expensive dimmer repairs. A tripped circuit breaker indicates a load fault that requires immediate attention.

Fault Diagnostics 21

Revision 1.0 - 7-May-02 HUB24 Series Dimmer Operating Manual

5.1.3 Thermal protection

The HUB24 dimmers primarily use convection cooling, so reducing the air flow to the unit can produce over-heating. The temperature of each of the heatsinks are individually monitored.

If the temperature of a heatsink gets close to maximum the fan on that heatsink will be turned on and a “Fan Activated” warning message is displayed (also placed in the error log). Press either button to acknowledge the warning and restore the display to normal.

If the temperature of a heatsink rises above maximum, all three dimmer channels on that heatsink will be will be shutdown. No indication of this shutdown is displayed. The channels will be restored when the heatsink temperature returns to a lower level.

5.1.4 Neutral – Earth voltage

The HUB24 will detect voltage problems generated by a poor or missing neutral connection. A poor (resistive) neutral connection can cause arcing and overheating of the connector and also allows the phase-to-neutral voltages to vary, causing overvoltage damage to components.

Bad neutral connections account for many lamp and dimmer failures. While the internal electronics of HUB dimmers can tolerate these fault conditions, other equipment run from the same mains supply generally cannot.

If the voltage between the neutral and earth exceeds the allowed maximum, all the dimmer outputs are turned OFF and a “Neutral Earth Fault” warning message is displayed (also placed in the error log). When the neutral-earth voltage condition is removed, press either button to reactivate the dimmer outputs. The outputs will restart according to the previous settings.

Neutral-earth voltages are most commonly caused by poor (resistive) neutral connections or undersized neutral wires in supply cables. Screw terminals in connectors can loosen with use and these should also be checked if this fault occurs.

The Neutral-earth fault detection can be disabled using the Fault Detect menu item (see section 4.2.17).

5.2 Output faults

If a short-circuit lamp or output cable is plugged into a dimmer output, the circuit breaker will disconnect the fault from the dimmer. In nearly all circumstances, it is quick enough to prevent damage to the output devices.

If an output device does fail the symptoms will be the dimmer output at a fixed level (off, half or full) regardless of the control level. If a fault does occur, that channel may be isolated with its circuit breaker.

Note: If a channel is not responding to DMX control, ensure it is not being controlled

by playback or test (see 4.2.24) before suspecting an output device has failed.

5.3 Software exception errors

If a message appears on the display like “ADR ERROR EXCEPTION XXXXXXXX XXXXXXXX” where the Xs represent different characters, write down the complete

message and contact JANDS Service Department or your local JANDS Distributor, giving details of the dimmer’s operating conditions that caused the error. Press either button to restart the dimmer, if the error prevents normal operation a Deep Clear will be required (see section 4.3).

22 Fault Diagnostics

Operating Manual HUB24 Series Dimmer

5.4 DMX faults

Loss of DMX signal will be indicated by “ – NO DMX – ” displayed at the bottom of the main screen. When DMX signal is lost, the dimmer will respond as configured until a new DMX signal is provided, or a Snapshot or Chase function is selected. See section

4.2.4 for configuring “Loss of DMX Signal”. Control consoles, when powered down, may transmit spurious DMX data which can

unintentionally cause dimmer channels to turn on. Because of this, after 10 minutes of no DMX signal the HUB24 will turn off all channels that were under DMX control.

The HUB24 is protected against internal damage from most high voltage faults on any of the DMX lines. Note that the protection circuitry may take up to a minute to reset after a fault is removed from a DMX line.

5.5 Phase fault indication

The three coloured Phase LEDs, located on the left of the display, will light when all three mains phases are present.

Phase A = Red Phase B = White Phase C = Blue

WARNING

IF ONE OR MORE PHASE LEDS ARE OFF, IMMEDIATELY DISCONNECT

POWER TO THE DIMMER AND CHECK THE MAINS SUPPLIES AND

WIRING BEFORE RE-CONNECTING POWER.

5.6 Cold lamp filaments

Cold lamp filaments consume considerably more power than warm filaments. This means that when a lamp is flashed to full, the surge current can be much greater than the rated current for the lamp.

The cold surge current to large lamps may be enough to trip the output circuit breakers. If such nuisance-tripping of the circuit breakers occurs, the filament maybe preheated using the control desk or programming a snapshot.

Preheating is turning a channel on a very small amount (around 1%) which heats the lamp filaments and increases their electrical resistance. The lamp filaments may show a barely perceptible dull red glow. When the lamp is then turned on full, the surge current is much less and the circuit breaker is less likely to trip.

Other advantages of preheating lamps are an increase in lamp life (due to the reduction of thermal shock to the filaments) and a reduction of lamp heat up time (the lamps will flash to full slightly faster).

5.7 Output minimum loads

The HUB24 dimmer outputs will correctly control all resistive and mains-voltage incandescent loads down to 60 watts and transformer-driven incandescent lamps (eg. pinspots and low voltage halogen lamps) down to 100 watts.

The dimmer outputs will also control the speed of most "universal" motors, however some motors will require a lamp plugged in parallel.

Installation 25

Revision 1.0 - 7-May-02 HUB24 Series Dimmer Operating Manual

6 Installation

6.1 Free Standing

The HUB24 is primarily convection cooled, with the main air intake at the bottom and air exhaust at the back and sides - these openings must not be obstructed.

Correct positioning and adequate ventilation are essential. The HUB24 must be in the upright position, standing on its feet. Allow at least 100mm behind, at least 200mm above and at least 100mm on each side of the dimmer.

Allowing for good airflow will serve to further reduce internal dimmer temperatures and will enhance the dimmer’s operational reliability.

6.2 Wall Mounting

The HUB24 may also be wall mounted in non-enclosed spaces. Mounting within cupboards is not recommended.

When wall mounted, allow at least 300mm above and at least 100mm on each side of the dimmer. It should be at least 200mm from the floor to avoid excessive ingr ess of dust and fluff.

Multiple HUB arrays should be spaced vertically with at least 300mm gap between the dimmers and no more than three dimmers high, to avoid excessive heating of the top dimmer. Horizontally there must be at least 150mm space between each dimmer.

The wall mounting bracket is an optional accessory. Place the wall mounting bracket against the wall, orienting it so the tabs are at the top. Mark and drill at least four fixing points and attach the bracket to the wall.

The HUB24 is attached to the pre-mounted bracket as follows:

1. Pull out the three phase cable from the cable tray.

2. While tilting, lift the HUB24 up and insert the tabs through slots in the top of the

rear panel.

3. Pivot down the HUB24 fully onto the bracket, being careful to position the three

phase cable in the cable groove.

4. Lock the HUB24 in place with two M4 screws through the bottom of the bracket.

7 Maintenance

WARNING

DO NOT ALLOW THE ENTRY OF LIQUIDS OF ANY SORT INTO

THE DIMMER CHASSIS.

EXTERNAL CLEANING:

If the front panel requires cleaning, wipe with a mild detergent on a damp soft cloth. DO NOT spray liquids into the chassis. DO NOT use solvents to clean the unit.

INTERNAL CLEANING:

The HUB24 dimmers require no internal maintenance other than periodic inspection for dust build up in the air-paths and on the heatsinks.

If the heatsinks are clogged with dirt or fluff, the dimmer must be disassembled by an authorised Jands service agent and the heatsinks cleaned.

Do not attempt to clean the heatsinks by blowing compressed air through the vent holes in the chassis.

ROUTINE MAINTENANCE:

• Test both RCDs each time the HUB24 is used.

• Inspect the heatsink surfaces for build up of dirt or fluff, which will reduce the

cooling ability of the heatsinks.

Touring dimmers may need a more rigorous maintenance routine, which should also include:

• Inspection of chassis for evidence of impact damage and physical abuse.

• Inspection of output sockets for wear and damage.

• Inspection of mains power cable for wear and damage.

• Electrical checking of ground integrity from power cable to chassis and power cable

to output socket grounds.

• Testing the front panel breakers isolate the outputs when switched off.

Note: The internal battery within the HUB24 will need to be replaced every 4 y ears or

whenever settings are not retained when the power is turned off. This must be done by an authorised Jands service agent.

8.2.3 Normal Three Phase plus Neutral Operation

The HUB24 is normally supplied with a three phase power cable and plug attached, suiting the vast majority of available mains supplies (ie. three phase and neutral).

The incoming mains supply must be protected by upstream circuit breakers or fuses rated at not more than the ‘Upstream protection’ value. This value is specified in the Technical Data and Specification table at the beginning of section 8. The dimmer’s circuit breakers are not rated to correctly clear faults if the supply protection is in excess of this.

The power cable is terminated within the dimmer at the four terminals on one of the RCDs and a chassis earthing stud.

8.2.4 Single Phase Operation

It is possible to supply the HUB with one single phase feed, where three phase mains supply is unavailable. The total current drawn by the HUB is limited by the rating of the neutral conductor in the mains cable.

Max total current 50 Amps. To extend these limits the HUB requires internal rewiring, contact the factory if this

is required.

Revision 1.0 - 7-May-02 HUB24 Series Dimmer Operating Manual

Appendix A Using the Dimmer Utility

The HUB24 and later HP dimmers can have updated operating software downloaded to them. The HUB24 can also have user definable dimming curves and custom logos downloaded to it. This is achieved using a PC Download cable, connected between the PC serial port and the dimmer’s DMX input connector.

Jands Dimmer Utility is a Windows-based custom editor and download application. It provides the following facilities:

• Download HUB24 operating software.

• Download HP12 & HP6 operating software.

• Edit & download dimming curves.

• Edit & download custom logos.

The Dimmer Utility software only sends files to a dimmer. A dimming curve or custom logo cannot be read back from the dimmer in order to make minor changes to it, so it is important to save all curves and logos on the computer as well.

These instructions assume the user has basic experience with Microsoft Windows. For help in this area consult the Windows manual or click Help on the Start menu.
