Important safety instructions

When using your lighting equipment, basic safety precautions should always be followed,

including:

1. The fixture should only be used by qualified personnel

2. Read and understand all instructions before using

3. The equipment must not be used by children. Close supervision is necessary when

any fixture is used near children. Do not leave equipment unattended.

4. The fixture and the accessories mounted onto the fixture may heat up to high

temperatures, so please handle with care.

5. Do not operate fixture with a damaged cable or if the fixture has been dropped or

damaged - until it has been examined by a qualified service person.

6. Position the cable so that it will not be tripped over, pulled, or make contact with hot

surfaces.

7. If an extension cable is necessary, a cable with a current rating at least equal to that

of the fixture should be used. Cables rated for less amperage than the appliance may

overheat.

8. Before the fixture is cleaned or serviced or while it is not in use, it must be completely

disconnected (by unplugging the mains cable). Disconnect the fixture from the ballast

unit. Never pull on the cable itself: pull only on the connector housing.

9. Let the fixture cool completely before putting away.

10. To reduce the risk of electric shock, do not immerse this fixture in water or other

liquids. An electric shock could be caused.

11. To reduce the risk of electric shock: take the fixture to a qualified service person

when service or repair work is required. Only original spare parts must be used to

guarantee long-term mechanical and electrical operating safety. Incorrect reassembly

can cause electric shock when the lamp is subsequently used.

12. The use of an accessory attachment not recommended by the manufacturer may

cause a risk of fire, electric shock, or injury to persons.

13. HMI fixtures emit levels of UV radiation similar to daylight . The UV-radiation safety

glass is integrated into the reflector and Softbox adapter attachment. The lamp base

should never be used without a reflector or Softbox adapter attachment.

Attention: Read before starting up

- For safety reasons, always disconnect the lamp base cable from the ballast unit

before opening the fixture for any purpose (e.g. to replace the lamp).

- To ensure maximum service life of the fixture, allow it to heat up for about 3

minutes without interruption. Always heat up with ballast dimmer set to full power.

- Because the unit emits a great deal of heat, the fixture must be located at a safe

distance whenever it is facing toward flammable and/or heat-sensitive surfaces o

objects.

- A hot lamp must never be placed in contact with flammable materials.

- Never use the fixture improperly, and be particularly careful not to obstruct the

natural circulation of air that keeps the fixture cool. Do not cover the reflector o

lamp base vent holes.

- To prevent overheating, never operate the fixture with the barn doors completely o

almost completely closed.

- The fixture is not suitable for use in explosion-hazard areas.

- Do not operate the lamp without a safety glass.

- Like natural daylight, HMI/MSR light contains a certain proportion of UV radiation.

The safety glass reduces the UV content to safe levels for normal operating

distances. When used at close operating distance, limit the exposure time o

unprotected skin.

- A ballast unit is necessary to use the fixture. The ballast unit provides for the

current supply to the fixture.

These fixtures conform to the protection class I, and for this reason may only

be operated on a mains supply with kobold electronic ballast units of

protection class I.

- Protect fixtures and accessories from falling down or out.

1. Start up

1.1 General information

The lamp base without a reflector or Softbox adapter are not provided with a

safety glass. The safety glass is integrated into the reflector or Softbox adapter

and serves to protect equally against broken lamps as well as noxious UV-

radiation. The fixture may therefore never be used without a reflector or Softbox

adapter with an intact safety glass. A cut-off switch is provided to protect the DW

575 and DW 800. Always check for proper function. The fixture is constructed

according to the protection norms IP54 and can be exposed to normal rain.

However the lamp should not be exposed to splash water.

Note: When using the Softbox adapter (bare bulb) with Softboxes or lanterns,

there is no weatherproof protection.

1.2 Starting up

1) Remove reflector

2) Insert lamp into lamp base

3) Mount Open Face reflector, PAR reflector or Softbox adapter.

4) Connect lamp base cable to the lamp base and secure it by tightening the cap

screw nut.

5) Connect lamp base cable to the electronic ballast unit and secure it by

tightening the cap screw nut.

6) Connect electronic ballast unit to the earthed/grounded mains socket.

7) Set the power switch on the ballast unit to ON.

8) Press green button of electronic ballast unit or lamp base; the fixture is

switched on and operational.

9) Press red button of electronic ballast unit or lamp base; the fixture is switched

off.

Occasionally a lamp may fail to trigger; if this happens, switch the fixture or ballast

unit OFF and then ON again.

Optimum colour temperature will be reached in about 3 – 5 minutes

To ensure maximum service life of the lamp, allow it to heat up for about 3 minutes

without interruption. Always heat up with ballast dimmer set to full power.

Make sure the ventilation slots on the fixture and the ballast unit are unobstructed.

1.3 Power regulation

When the fixture is used with a kobold ballast unit, it is equipped with electronic

output dimming. This dimming function allows light output to be reduced

continuously down to about 60%. Please note that depending on the type of lamp

used, colour temperature may change with output. kobold ballast units are

equipped with an electronic control of the heating up process. It controls during the

heating up process automatically on full power until the operating temperature is

achieved.

1.4 Remote control ON/OFF

Remote control (on): The ballast units are supplied with an active remote control

mode. The function is as follows: If the operating fixture becomes switched off due

to an interruption of the mains supply, it will turn on again, as soon as the mains

supply begins to function.

Remote control (off): If the fixture should not be switched on automatically when

the current comes back, this function can be activated on the ballast unit by re-

plugging the contact bridge into another socket. The contact bridge is situated on a

printed circuit board in the inside of the unit, and may only be moved by a

specialist.

2. Operation of the lamp

2.1 Mounting and dismounting the reflectors and Softbox adapter

Before mounting the reflector or Softbox adapter, the knurled screw of the locking

mechanism (8) must be loosened by turning it counter-clockwise. A reflector or

Softbox adapter is now inserted with the marking towards the top by introducing

the 3 pins into the corresponding slots (11) and turning the reflector clockwise until

the pin (9) snaps into the locking position.

By tightening the knurled screw (8) the reflector or Softbox adapter are securely

locked. For safety reasons the knurled screw must always be well tightened.

Before taking off the reflector or Softbox adapter, the knurled screw of the locking

mechanism must be loosened by turning it counter-clockwise. By pulling the

mechanism backwards, away from the reflector, the locking mechanism is

loosened and the reflector or Softbox adapter can be turned counter-clockwise to

be removed.

2.2 Mounting and dismounting the accessories to the Open Face reflector

4-leaf barn door: Before mounting the barn door, completely loosen the knurled

knob on the locking (20) mechanism. Place the movable roller (21) on the reflector

edge (15), push down to compress the spring in the mechanism and slide the

remaining two rollers over the reflector edge. To ensure that the three rollers have

a secure hold on the reflector edge, rotate the 4-leaf barn door. Now that all 3

rollers are secured, tighten the knurled knob (20). For safety reasons, the knurled

screw must be tight during operation of this light at all times.

Conversion filter/ diffusion filter: The filter slot is part of the 4-leaf barn door.

Turn the 4-leaf barn door until the flap of the filter slot (18) is at the top. Open the

flap of the filter by the handle, insert it completely into the filter slot (18) moving it

45° sideways until the filter handle corresponds with the safety hole of the grip at

the corner of the barn door. For safety reasons check that the slot flap is

completely closed.

2.3 Mounting and dismounting the accessoires to the PAR reflector

4-leaf barn door: Unlock and flip up the top barn door claw (17) by pushing in the

marked direction. The 4-leaf barn door for the PAR reflector can now be inserted

from above in the outer fixed groove of the three lower barn door claws.

Lower the top barn door claw until it engages and locks. To ensure that the barn

door is securely fitted, rotate the barn door.

PAR lens, Fresnel lens: Unlock and flip up the top barndoor claw (17) by pushing

in the marked direction. Select a PAR or Fresnel lens and insert from above in the

inner fixed groove of the three lower barn door claws. Lower the top barn door

claw until it engages and locks. To ensure that the barn door and lens are securely

fitted, rotate the barn door.

Scrim ring: Unlock and flip up the top barn door claw (17) by pushing in the

marked direction. The scrim ring can now be inserted from above (behind the 4-

leaf barn door) in the outer fixed groove of the barn door claws. Lower the top barn

door claw until it engages and locks. To ensure that the barn door and lens are

securely fitted, rotate the barn door.

2.4 Focusing

Use the rotary knob (3) on the rear of the lamp base to adjust the focus; note the

corresponding flood and spot symbols on the lamp base indicating the adjustment

directions. By using the lamp base with an Open Face or a PAR reflector with a

mounted Fresnel lens, the complete focus range can be used. By using the lamp

base with a PAR reflector with or without mounted PAR lenses, be aware that only

a part of the focus range can be used.

Note: Gel filters can also be used instead of mounted glass filters. Attachment

clips (19) for these are located on the two wide door leafs.

2.5 Inserting or replacing a lamp

Before replacing the lamp “attention hot lamp”, switch the ballast unit OFF and

disconnect the fixture from the ballast unit.

- Remove accessories including 4-leaf barn door (see section 2.2-3)

- Unlock reflector

- Carefully pull out the reflector

- Carefully insert the lamp into the ceramic socket, align the two pins with the

holes in the socket and push it in all the way. The two spring clamps (10)on the

lamp socket must engage the lamp’s ceramic base. Be careful not to tilt or jam

the lamp while inserting it, and handle the lamp only by the base in order to

keep the quartz glass free of fingerprints. Any fingerprints or other marks on the

quartz glass must be immediately removed with a clean cloth moistened with

solvent or alcohol. No warranty or replacement obligation applies to lamps that

have been damaged by improper insertion.

- Before mounting the reflector or Softbox adapter check that the safety glass is

intact. Safety glasses which are scratched or otherwise damaged must always

be replaced.

- Carefully reinsert the reflector (see chapter 2.1) or Softbox adapter back into the

lamp base; push it smoothly and exert only minimal force.

Lamps of different manufacturers are subject of a certain tolerance. To adjust the

lamps in the optimal position (spot) to the reflector, the lamp can be adjusted with

the setting screw (5).

Attention! The safety glass provides protection in the event of a lamp

exploding, and UV radiation. Never use the fixture without an

intact safety glass.
