IMPORTANT

Installer and Users please note:

These instructions should be read carefully and left

with the user of the product for future reference.

Installation

Fix the Quasar HX with the hanging bracket provided. To conform to Health & Safety Regulations, a safety chain must also be employed.

The Quasar HX must be installed by a competent electrician in accordance with the current IEE wiring regulations.

Connect the Quasar HX to the mains supply with the lead provided. The wires are colour-coded as follows:

• Brown = Live (phase)

• Blue = Neutral

• Green/Yellow = Earth

• The Quasar HX must be earthed for safe and reliable operation. The supply must be fitted with an isolating switch, or plug and socket,

and protected by fuse or circuit breaker rated at between 6A and 16A. If the Quasar HX circuit is connected via an MCB then it is recommended that a time-delay MCB is used (Type 3 or Type C to BS3871). This will reduce the possibility of "nuisance tripping" due to the lamp switch-on current.

This symbol means that, in order to reduce the risk of fire,

0.8m

It is also possible to connect the Quasar HX to a switching pack such as the NJD SP10000 but this is not recommended. If connecting via a power pack, ensure that the outputs of the power pack have sufficient capacity to switch the VA rating of the Quasar HX. The Quasar HX must not be connected to a dimming pack or light dimmer. This is unnecessary as the Quasar HX has a built-in dimmer. The Quasar HX is an inductive load.

The Quasar HX is supplied with its handle attached. The handle can be lengthened or shortened by removing it from the unit and attaching it using the higher or lower set of fixing holes.

By removing the handle completely, and re-assembling the other way round, the Quasar HX can be tilted in the opposite direction.

Fix the Quasar HX securely, and fit a safety chain to the loop provided. Tighten the handle fixing screws with the Allen key provided.

the Quasar HX should be installed more than 0.8 metres from any object that it is illuminating.

User Guide Quasar HX

The Quasar HX should be operated with the fan at the lower end and the mirror barrel at the upper end. Operating the other way up may reduce lamp life.

Adjust the hanging bracket until the light beams are in the best position. The Quasar HX may be moved whilst it is operating provided that it is done carefully. The lamp is most vulnerable to mechanical damage immediately after it has been switched off. It is recommended that the Quasar HX is allowed to cool for 5 minutes after switching off before moving.

Changing the lamp.

Disconnect from the mains supply. Slacken the knob on the lamp cover and remove the lamp assembly. Remove the lamp connector and light screen from the back of the lamp. Remove the lamp from its clip, and replace by a new lamp type A1/259 (ANSI Code: ELC). Replace the lamp connector and light screen, re-fit into the unit and tighten the fixing knob.

Changing the fuse

If the fuse blows, replace with a new fuse type 20mm x 5mm 3.15 Amp Anti-surge, High breaking capacity. This type of fuse has a ceramic case. Do not replace with any other type or value of fuse. If the new fuse blows, consult a dealer. The fuse is located in a small drawer beneath the mains inlet connector (remove the mains cable to gain access).

Focusing.

To focus slacken the focusing control on the front of the unit, move forwards or backwards as required, and re-tighten the screw when the best image is obtained.

Cleaning.

The Quasar HX should be cleaned periodically as the light output will become less intense as smoke fluid residues build up on the mirrors and lenses.

Disconnect from the mains supply and remove the cover as follows: Remove the 6 screws at the positions indicated by the arrows using a #2 Pozidriv screwdriver. The top section of the cover can be lifted off vertically to gain access to the optics. Clean the lens and the mirror

using a soft lint-free cloth and methylated spirit, isopropyl alcohol or hi-fi cleaning fluid. Also, make sure that the fan is not becoming obstructed.

Page 4

User Guide Quasar HX

The Quasar HX has a temperature controlled fan, which will only operate when the internal temperature exceeds 50°C. If the fan is

obstructed and the internal temperature exceeds 70°C the lamp brightness will be gradually reduced to prevent heat build-up. If the internal temperature reaches 100°C, the lamp will be turned off. The Quasar also has thermal switch which will cut off all power to the unit if it overheats due to the ventilation being obstructed.

Setting up.

Setting the lamp brightness.

There are 10 lamp settings, allowing the brightness to be set as shown below. Press the SELECT button, until the letter L shows in the left-hand display, with the figure in the right-hand display flashing. Press the

ADJUST button until the correct setting is shown.

The figures in bold correspond to the two settings of other NJD lighting products fitted with a lamp brightness switch. The Quasar HX contains a circuit which adjusts the power to the lamp as the mains voltage varies. Brightness and lamp life will remain constant provided the mains voltage does not vary outside the limits set in BS7697.

In modes where DMX control of the dimmer is available these figures correspond to the full brightness setting of the dimmer. Operating at lower settings of the dimmer with further increase lamp life.

User Guide Quasar HX

Operating modes.

The Quasar HX may be operated in one of four different Modes.

1) Independent or Master/Slave see page 6 The Quasar HX can be set to move to each bass beat, or continuously,

going through a sequence of patterns at random, along with colour and gobo changing. In this mode it can also be enabled and disabled from a remote switch or switching panel.

2) Externally controlled from any DMX controller such as Merlin, IQ-MX80, IQ-MX60 or IQ-MX40. see page 8

The IQ-MX80 has 10 preset programs, 10 user-programmable programs, real-time programming and a joystick. and can control any number of Quasar HXs and Predator HXs arranged as up to 16 channels.

The IQ-MX40 can control 4 channels of Quasar HXs and has a total of 256 selectable functions including fourteen patterns, each with selectable colour/gobo, four different colour/gobo change modes (fill, random, shift and sync), and four different run-sequences of colours and gobos.

The IQ-MX60 includes all the functions of the IQ-MX40, plus two userwritable programs, and a joystick for manual control.

With a programmable DMX controller such as Merlin, up to 32 channels of Quasar HXs can be controlled, there is no limit to the number of Quasar HXs on each channel. The beam can be positioned to an accuracy of 0.7°, and the colour/gobo can be selected.

3) Externally controlled by Midi. see page 11 The mirror movements, colour, gobo, strobe and dimmer can be

controlled from a Midi sequencer.

4) Analogue control from a 0-10V output controller see page 14. 0-10V can be used to directly control the colour, gobo and beam

movement.

Synchronizing other Quasars.

To synchronize other Quasar HXs without a controller, proceed as follows:

• Connect a DMX lead from the DMXout socket on the first Quasar HX to DMXin on the second, from DMXout on the second Quasar HX to DMXin on the third, and so on.

• Connect a terminator to the DMXout socket of the final Quasar HX. A terminator is a 5-pin XLR plug with a 120W resistor connected between pins 2 and 3. Set the other Quasars as follows:

• Set the function to F1 or F3. Use F1 to make the slave units copy the master exactly, or F3 to make them reverse the movement of the barrel

scan.This is useful if two groups of Quasars are mounted facing each other as it means that they all move in the same direction.

To set the function press the SELECT button, until the letter F shows in the left-hand display, with the figure in the right-hand display flashing. Press the ADJUST button until the correct setting is shown.

• Set the DMX address to 001.

To do this, press SELECT until the hundreds digit flashes, and then press ADJUST until it shows 0. Press SELECT until the tens digit flashes, and then press ADJUST until it shows 0. Press SELECT until the units digit flashes, and then press ADJUST until it shows 1.

• If Quasars are being controlled in groups of four, it is possible to obtain colour and gobo changing patterns, whilst the beam movements are synchronized. To do this. set the DMX address as shown below:

Analogue Control.

The Quasar may also be controlled by six 0-10V analogue inputs, To control by 0-10V, set the function to F9, or F10.

F9 = Analogue control of position F10 = Analogue control of speed

The analogue inputs control the Quasar as follows:

Additional Technical information

The DMX system is a high-speed digital data system, which can transmit all the information required for light dimmers, multi-motor lighting effects etc. down a single cable. It was invented in 1986 by the United States Institute of Theater Technicians for the control of dimming theatre lighting, and has since been adapted for the control of intelligent lighting.

The Quasar HX outputs a DMX signal when operating from its own microphone, which can be used to synchronize other Quasar HXs. Up to 32 units that can be connected to the DMX signal, but it is not recommended that the total cable length should exceed 250m.

Each unit connected to the DMX signal is given an address, and it compares this to the data being sent on the DMX cable, so it can determine which data is addressed to it. It then uses this data to move a motor or set a brightness level as required by the controller.

As the DMX system can transmit as much information as 512 analogue control wires down a single cable, it has to transmit very quickly, in fact, at a frequency 12 times higher than the highest audio frequency. Anyone who has used long leads for audio will realize that it is difficult to do without losing the higher frequencies. To make the DMX system work at such high frequencies, it requires special circuitry and special cable. Cable can be designed to pass high frequencies with no loss if it has the correct resistance connected at each end, this resistance is called the characteristic impedance of the cable. DMX cable has a characteristic impedance of 120W. Most good quality low-capacitance screened twisted pair cables will work, but twin individually screened will not. Also, if the cable is split or joined other than end-to-end, the system will stop working.

If making your own leads, it is important to use good quality connectors and make sure that the soldering is of a high standard.

Standards

The Quasar HX complies with the following British and European Standards:

EN55015 - Electromagnetic Compatibility. EN60598 - Electrical Safety Standard for Luminaires.

• Does not start and go through set-up procedure, LED not lit

No mains supply - check mains lead Fuse Blown - check fuse.

• Sets up, but does nothing

10V enable not connected.

• Lamp not lit

Lamp failed - replace lamp. Product has overheated and shut down - check ventilation

• No response to sound

Set to a mode that does not have a sound response - change F settings.

• Erratic response to sound

Music not loud enough.

• Light output dim.

reflector or lens dirty - clean lamp misaligned in reflector. lamp blackened (about to fail) Lamp set to a long life setting - change L setting.

Synchronized mode

• Changes colour when it should move left-right, moves left-right when it should change colour

DMX address on slaves not set correctly - should be 001, 009, 017 or 025

• Movement erratic.

Wrong type of cable - DO NOT use twin individually screened Unterminated DMX line in DMXout XLR socket of final lantern - fit a

terminator to the DMX out socket of the final lantern

• No movement

DMX XLR plug not in socket correctly. - check XLR plugs DMX lead broken or incorrectly wired. - check leads

DMX controlled mode (see also synchronized mode)

• No movement

DMX address set wrongly - check DMX address settings, or see if lantern responds to a different address.

• Lamp off but mirror barrel moving

Lamp failed - replace Lamp dimmer channel set to zero

• Light output dim

Lamp dimmer control set to a low level Lamp set to a long life setting - change L setting.

Portable Appliance Testing

The Quasar HX should be checked for Electrical Safety annually, and if it is hire equipment, before it is hired out. A high-voltage test (at 500V or 1000V) should be carried out between live and earth, and an earth bonding test between the case and the earth connection (at 10A or 16A). Insulation resistance should be greater than 10MW and earth bonding resistance less than 0.1W. A high voltage test may also be carried out between the DMX and analogue inputs and live, if the equipment has passed the live-earth test.

Not all parts of the case are bonded to earth - these are separated from live parts by double insulation.

Do not test high-voltage or earth bonding between DMX or analogue inputs and earth - this will destroy the electronics.

Note: a common cause of failure of the insulation test is the build up of smoke fluid inside the lantern.
