The SPOTWASH-3048 is a moving head rotating
around two axes (pan / tilt) . It is used for effect illu-
mination, e . g . in function rooms or on small stages .
The moving head is a combination of a spotlight
(equipped with a white 30 W LED to produce a
narrow, hard-edged light beam and a gobo wheel
to project light patterns) and a washer (equipped
with six 8 W RGBW LEDs to produce a wide, soft-
edged light beam) .
The unit is designed for operation via a DMX
light controller (10 or 17 DMX control channels);
however, it can also be operated without a con-
troller, either independently or in combination with
multiple SPOTWASH-3048 (master /slave mode) .
4 Setting Up / Installation
•
To prevent heat accumulation inside the unit,
always position the unit so that sufficient air cir-
culation will be ensured during operation . Never
cover the air vents of the housing .
•
Always keep a minimum distance of 50 cm to
the illuminated surface .
Set up the unit on a solid, flat surface . Alternatively,
install it upside down on a lighting stand system
(e . g . crossbar) by means of the mounting bracket
(8) provided: Use the two hexagon socket screws to
fasten the bracket to the centre of the base plate,
and then use a suitable support (e . g . C hook) to
install it on the lighting stand system .
WARNING Install the unit safely and expertly .
When the unit is installed at a
place where people may walk or
sit under it, additionally secure it:
Screw the eyebolt (7) provided
into the threaded hole of the base
plate . Then attach a safety rope to
the eyebolt so that the maximum
falling distance of the unit will not
exceed 20 cm .

5 Control Connections
The SPOTWASH-3048 is equipped with 3-pole XLR
control connections (4): a DMX input (DMX IN) and
a DMX output (DMX OUT) .
The units to be controlled are connected in a chain
to the unit sending the control signals . For connec-
tion, use special cables for DMX signal transmission
(e . g . cables of the CDMXN series) . For a total cable
length exceeding 150 m or when controlling more
than 32 units, it is generally recommended to insert
a DMX level matching amplifier (e . g . SR-103DMX) .
5.1 Connection to a DMX controller
To connect multiple DMX-controlled units to a DMX
light controller (fig . 4), proceed as follows:
1) Connect the DMX output of the controller to
the DMX input of the first DMX-controlled unit .
2) Connect the DMX output of the first DMX-con-
trolled unit to the DMX input of the second
DMX-controlled unit . Proceed in the same way
to connect the output of the second unit to the
input of the third unit etc . until all DMX-con-
trolled units have been connected in a chain .
3) To eliminate interference in signal transmission,
in case of long cables or a multitude of units
connected in series, terminate the DMX output
of the last DMX unit in the chain with a 120 Ω
resistor (> 0 .3 W): Connect a DMX terminating
plug (e . g . DLT-123) to the output jack .
5.2 Master /slave mode
Synchronous operation of multiple SPOTWASH-3048
with the same show program is also possible with-
out a DMX controller . The first unit (master) will
control the other units (slaves) . Connect the units in
a chain according to chapter 5 .1; however, do not
connect the DMX input of the master unit (fig . 5) .
