Dear customer!
Please read the safety instructions and product description carefully before working with
these lights for the first time.
Please follow the separate mounting instructions for ceiling- and wall-mounted lamps, and for
fitting the stand foot and pipe.

1. Safety instructions
Please pay attention to the directions for use when handling the lamp.
Attention:
This device is not suitable for use in hazardous locations.
The lamp is classified as a Group 1 device according to the regulations for EEMP.
Repairs to the lamp and special installation work on the reflector or plug-in socket
should only be carried out by ourselves or a company expressly authorised by ourselves.
The manufacturer is only responsible for the safety of the lamp if repairs and alterations have been carried out by themselves or a company who can guarantee that the
safety regulations have been observed.
The manufacturer is not liable for personal or material damages if the lamp is misappropriately or incorrectly operated or misused.
The lamp body may only be dismantled from the swivel-arm (in reverse order to its assembly) after the assembly locking device has been inserted and tightened since the
arm is under spring tension.
Make sure that the lamp is in perfect working order before use.

2. Operating the lamp Quintaflex
2.1 Checking the lamp Quintaflex with light intensity control
The lamp Quintaflex is optionally equipped with the function of electronic light intensity control. You can
adjust the light intensity at the key pad on the cardan bow.
♦ Voltage measurement and setting
Before using the OT-lamps, a voltage measurement and, if necessary, a voltage setting has to be done.
Only in this way a perfect functioning can be ensured.
If the location of the lamp is changed, the voltage measurement and setting must be repeated.
♦ Voltage measurement at the halogen bulbs
Screw
To measure the voltage proceed as follows:
Mount the lamp to the ceiling or wall attachment.
Switch on the lamp.
In order to make the measurement, remove the
cover.
The cover is fixed with two screws, as shown in the
figure. Loosen the two screws, remove them and
take off the cover.

Measuring points
Measuring points
♦ Voltage setting at the halogen bulbs
The measuring points for checking the voltage are
in the same position at all Quintaflex-lamps.
The measuring points are shown in the figure.
At measuring points 1 + 2 measure the voltage
applied at the halogen bulbs. The lamp is set to
the maximum light intensity.
The AC or DC voltage depends on the external
power supply.
Rated voltage 22,8 – 23,8V.
If the voltage measured is too high or too low, the
value must be adjusted at the power supply.
The setting at the transformer is made by reconnecting the wires on the secondary side.
Measuring points 1+2

♦ Voltage measurement at the control board
Please check, whether the power supply is supplying AC or DC.
Voltage measurement at DC
Pay attention to the polarisation during the installation.
If the light intensity control does not function as desired, the PLUS- and MINUS-pole at the power
supply have to be changed.
Voltage measurement at AC
For installation at AC proceed as described below:
• Preparation
The lamp is already switched on. Set the lamp to
the lowest light intensity
• Measurement
Measure the voltage at measuring points 3 + 4. The
voltage must be less than 40V DC.
If this value is exceeded, reset it as described below:
.
Measuring points
♦ Voltage setting at the control board
Control board
J4 J5
Switch the lamp off.
The position of the control board is shown in the
figure.
Adjust the standard setting by changing the jumpers (see arrow).
Three settings enable you to ideally set your lamp
system (J4 and J5).
J5 J5 J5
J4 J4 J4
J5
J4
Take off one jumper and put it into position as
shown in figure II. or III.
Switch on the lamp. Set the lamp to the lowest
light intensity.
Repeat the voltage measurement at measuring
points 3 + 4.
If the voltage is less than 40V DC, keep the chosen
setting.
I. II. III.
If you measure a voltage in excess of 40V DC, switch off the lamp.
Replace the first jumper to the initial position.
Take off the second jumper and place it back on one of the two pins.
Switch on the lamp again. Finally repeat the voltage measurement. The voltage is now adjusted.
Close the lamp by replacing the cover.

2.2 ON/OFF switch
There are no ON/OFF switches on the lamp head.
The customer must provide a two-pole ON/OFF
switch.
2.3 Positioning
For positioning use sterilizable handle 1.
Handle rail 2 is used for adjusting the lights from
the outside.
The cardan bow 3 is used for convenient, fully cardanic adjustment of the lamp.

In case of low room heights the lamp is delivered
with a central spring arm. The spring arm has only
one joint.
The coupling for the bow of the lamp body is fitted
with a needle bearing. The inner ring 4 of this needle bearing has already been pushed on the axis of
the lamp bow.
Remark:
The instructions mentioned above refer to
ceiling and wall models.

2.4 Light field adjustment
(merging of light fields)
The lamps Quintaflex are equipped with the func-
1
tion of light field realignment.
That means, you can merge the separated light
fields to one spot as shown in the figure.
To activate the light field realignment turn sterilizable handle 1.
