4. Basic functions

 Securing the ﬁ xture

The lamphead must be fastened at its stirrup (9) in a standing or hanging position. The spigot (8) must be inserted into the

husk of a matching stand or a matching holding device and must be clampt in and secured there.

 Rotation and tilt

The lamphead can be rotated after the screw at the stand or holding device has been loosened. In order to change the tilt,

loosen the tilt lock (10). After rotating or tilting the lamphead, the screws or lock levers must be tightened again.

 Adjusting the beam angle

The beam angle can be continuously adjusted by turning the focus knob (13). When you do this the entire lens unit is moved out

of or into the lamphead housing.

This mechanism protects the ﬁ xture in two ways:

· A predetermined breaking point prevents damage at the lamphead if the focus knob is turned with too much torque.

· A self-impeding gear prevents that the position of the lens unit changes while the lamphead is operated in a tilted position.

 Using accessories for light design

Accessories for light design, such as a barndoor or ﬁ lter holders, can be inserted into the holding brackets on the front of the

lamphead. To do this proceed as follows:

· Firmly press the button at the side of the top latch; the top latch ﬂ ips upwards.

· Insert the accessory from the upside into the holding brackets, until the safety catch (12) engages. Slightly tilt the safety catch

with your ﬁ nger for support.

· Close the top latch (11) and make sure that the hook of the top latch engages in the holding ring of the accessory.

 DMX interface

The lamphead is equipped with an RDM/DMX interface with a waterproof input socket. The not waterproof DMX distributor box

which is mounted at this socket has one DMX in and out and has the purpose of looping the DMX line throuhg to the next

lamphead. It can be removed after loosening the ﬁ xing screw.

 USB interface

The lamphead is also equipped with a USB interface with a mini USB slot, which can be used for updating the ﬁ xture's

internal ﬁ rmware, for adjusting operating parameters and for service purposes. The service tool "LSeries Manager" allows you to

conﬁ gure your lamphead via this interface, you can download the LSeries Manager from the ARRI homepage free of charge.

 Turning on and operation

After you have turned on the power switch (or after connecting to mains power for lampheads without a power switch) the

lamphead will need a short start-up time before it lights up. The lamphead will operate with the previously used setting. It can

now be controlled via the DMX interface or the on-board control.

CAUTION! Hight beam intensity ! Do not look into the ligth emission aperture of the lamphead.
