2 Description of Function
The GC 335 is an active infrared triangulation scanner.
The GC 335 has been designed for detection traveling on the door leaf.
2.1 Principle of Operation
Any objects entering the protected area will be detected by the infrared beams and will cause the relay
outputs to be switched off.
The beam spot produced by the infrared beam on the ground is approx. 1,1 cm x 8,3 cm in size (at a
mounting height of approx. 2 m).
The angle of the two lens systems can be modified by an adjustment mechanism. A detection range
(detection height of objects) of up to a maximum of 2.50 m can be set. The sensing range of the device
is set to maximum at the factory. The device has been fitted with an optical adjusting tool.
The sensor reacts to objects in the detection range largely independently of the surface color and struc-
ture. Reflecting and very dark objects are detected as well.
Several sensors can be operated in a master and slave combination in order to be able to adapt the
area protected to the prevailing conditions.
By means of a six-pole screw terminal the master module is connected to the door control. The slave
modules are connected to and supplied by the master module by means of flat cables. The master
module and the slave modules are located in an aluminum profile together.
3 Installation and initial Operation
3.1 Installation Check List
3.1.1 Installation of Aluminum Section
1. Push the module holder (c) into the aluminum profile (b) and position the module holder at the
points where the modules will be mounted later.
2. Drill the fastening holes in the middle between the module holders (in Fig. 3.1 grayed surface).
Make sure that no chips remain in the aluminum section.
Seal the borehole when fastening in such a way that no dripping water can penetrate.
Mechanical information which may facilitate the positioning of screws:
Figure 3.1 Mounting the aluminum section
3. Only use screws with a flat head to fasten the aluminum section, and mount the aluminum section
(b) at the intended mounting height (maximum 2.50 m).
The intended use of GC 335 is to secure automatic swinging door in keeping with
German standard DIN 18650 / EN 16005. If used as intended, the sensor shall influ-
ence the door movement through the safe door control only and not by direct inter-
vention as only the entirety of safe door control and sensor constitute a protective
device of Category 2 EN 954/1.
The modification of the construction/ arrangement of the installation without consul-
tation with the manufacturer could lead to dangerous situations.

3.1.2 Installation of the Module
1. Set the transmitters of the modules identically at all modules to be used (cf. Figure 3.3). -> For
this purpose, push the transmitter adjustment always in direction of the flat conductor cable
(the flat conductor cable side is opposite the closing edge).
2. Connect all required flat conductor cables to the modules prior to the installation of the modules.
3. Please make sure that the master module is always located on the hinge plate side.
4. Connect the terminal screw (i) of the master module to the transition cable of the door control.
5. Place the modules between the module holders (c). Subsequently use the screw M2.5 (h) to
screw down to the module holder (cf. Figure 1.1).
6. Use nippers to cut the configuration bridge (j) out of the PCB of the last module (last slave module
or individual master module) (cf. Chapter 5).
7. Set the angle of inclination and the detection range in keeping with Chapter 3.2.
8. Place the housing orifice (a).
9. Subsequently screw down the end caps.
10. Finally, check the detection range for each beam.
3.2 Setting the monitoring Beam - closing Edge
Set the transmitting or receiving beam upright in order to secure the closing edge as best as possible.
Figure 3.2 Explanation of the monitoring beam setting at the closing edge
Use two lock position to set a monitoring edge flush on the left or right side of the transmitter (cf. Figure
3.3.).
Figure 3.3 Setting the monitoring beam to the closing edge
In the factory default setting, all transmitter modules are preset to position 1 and the sensing range to
maximum. Position 1 means that the transmitter is straight and the closing edge is on the left (cf. Figure
3.2 left).
Make sure that the transmitters are all set identical in case of several slave modules (identical lock po-
sition of the transmitter) ! The master module has to have the same transmitter setting as well.
The transition cable to the door control can be passed through the end cap by
means of a cable bushing.
If you use the accessories "GC 335 Ergänzungskit IP54", please fix a double-faced
scotch tape between the profile and the mounting surface. This avoids the intrusion
of water through the drills of the sensor profile.

3.3 Optical Setting of the Sensor
You can swivel the detection field away from the door or towards the door by setting the angle of incli-
nation. The angle of inclination can be varied continuously from 0° to + 25°.
Use the handle on the chassis metal to set the angle of inclination.
For the adjustment of the angle of inclination use the M3 screw (g) at the top of the module holder.
Figure 3.4 Setting the angle of inclination
Use the detection range screw (f) to adjust the detection range.
By turning the detection range screw (f) with a screwdriver and the displacement of the receiver lens
caused, the detection range can be set.
An optical adjustment tool (LED green / red (p)) facilitates the exact adjustment of the detection range
over the ground.
If the sensor is not used for protection in keeping with German standard DIN 18650 /
EN 16005, a higher adjustment (no more than 80 cm) is possible.
Figure 3.5 Adjustment of the detection range
LED display:
LED red: Lens has been detected.
LED green: Free protected area and the sensor sees the ground.
Use the optional calibration tool (test card and square) for adjustment.
Detection range adjustment of the Sensor:
1. Use the chassis lever to set the module to the first marking line on the module holder (cf.
Illustration 6.3), and use the M3 screw to fasten (g).
2. Turn the detection range screw (f) counterclockwise until the overturn protection is activated
(slight "clicking" noise). Now the maximum detection range has been set.
3. Now use the test card and place it on the test specimen in such a way that it lays 12,5 cm above
the ground.
4. Turn the detection range screw clockwise until the LED display just switches from red to green (if
necessary turn back to red and then clockwise to just into green).
The detection range adjustment is thus completed.
If used as a means of protection in keeping with German standard DIN 18650 /
EN 16005, the angle of inclination and the detection range have to be adjusted as
follows:
0˚
25˚
EN

Angle of Inclination of the Sensor:
5. Lay the test card on the ground with the marking parallel to the door.
6. Rest the test specimen to the marking on the side of the door (cf. Figure
3.6).
7. The sensor points down vertically.
8. Use the chassis lever to swivel the sensor forward until it detects the test
specimen raised by 20 cm (LED = red).
9. Swivel the sensor further to the front until it just sees the ground again (LED
switches from red to green).
10. Now use the M3 screw (g) to attach the module to the module holder. The
angle of inclination has now been set.
This setting is now completed.
Checking the Detection range adjustment
11. Use the test card to check the detection range adjustment once again.
Figure 3.6Positioning the test specimen
4 Detection Field
Depending on the requirement and the door width, a master module can be supplemented with up to
seven slave modules.
We recommend to adjust the straight transmitting / receiving beam of the corresponding sensor mod-
ule no further than 10 cm away from the closing edge.
.Figure 4.1 renders information on the installation for different door leaf widths.
Figure 4.1 Detection field
The wider the door leaf is, the more slave modules are required.
For the operation as a safety sensor in keeping with German standard 
DIN 18650 / EN 16005, the detection range has to be set to approx. 
12,5 cm ±1 cm over the ground.
The following sensor characteristics do not conform to the safety regulations outlined in
the EC declaration of conformity:
- The distance between the modules and the main locking edge is greater than 10 cm.
- Gaps are left between the modules.
- The right/left adjustment position of the modules is not aligned with the main locking 
edge.
- The modules are set to a sensing height greater than 20 cm above ground level.

9 Disposal, Repair, Maintenance
9.1 Disposal
Dispose of the useless device in keeping with the applicable national legal regulations.
For example, take the sensor to a pertinent collection point for electronic waste.
9.2 Repair
Defective device may be repaired by the manufacturer only.
9.3 Servicing
Observe the applicable national regulations for servicing.
The sensor is maintenance-free by and large.
Nonetheless, check the technical safety of the sensor system in regular intervals, watching out for dam-
age of the housing in particular.
If it has to be assumed that a safe operation is no longer possible, the sensor system has to be shut
down and secured against unintentional operation.
Check the sensor for soiling occasionally. In order to clean the sensor, use a dry or moist soft cloth to
wipe across the sensor in regular intervals. This action will ensure an optimal function.
The housing is made of plastic. For this reason avoid contact with acetone and detergents containing
solvents.
