Laser
If the functionality is not ensured, the error output is immediately activated. The laser output
power and the rotational speed of the mirror are continuously monitored by the built-in
control system to ensure that the requirements of laser protection class I are satisfied.
A reference measurement cyclically controls the measurement function. The following functions are checked on each rotation of the mirror by means of a test object located inside of
the device:
• optical systems (e.g. transmitter and receiver)
• hardware, software, etc.
Window monitoring
A total of six light axes monitor the degree of soiling of the window. During this procedure,
the results are compared with two reference sensors. Moreover, these reference sensors
are used for temperature compensation and ageing monitoring.
Monitored processing
The processing of measurement values in the rotoScan ROD 4… is monitored by a separate component, i.e. errors in program execution are detected immediately and appropriate
protective measures initiated.
Software test
The entire system is tested when first switched on and during operation.

• Only objects that are in clear view of the sensor can be detected.
• Objects such as glass panes and mirrors that do not reflect light back to the sensor
cannot be safely recognised.
• The response time must be considered when working with fast-moving objects.
• Objects with reflectivities of at least 1.8% (e.g. black cord) can be reliably detected by
the ROD 4/ROD 4-06 in the respective detection areas.
The ROD 4-08 detects objects with a luminosity coefficient of at least 6%.

Device types
Four programmable detection zone pairs make possible an optimal adaptation to the applications. A detection zone pair is considered to be the combination of both an internal and an
external detection zone. Inner and outer detection zones each have a different colour
display.
The ROD 4… unit can be used for mobile (driverless transportation systems, side-tracking
skates, …) as well as for stationary applications (projection control, …).
The long-range and contact-less measurement principle makes the ROD 4… unit a universally applicable monitoring device.

TNT 35/7-24V
The ROD 4… device is an optical distance sensor. It could also be considered an optical,
area radar unit. The device periodically transmits light pulses within a working field of 190°.
If the pulses are incident upon an obstacle or a person, the light is reflected and received
and analysed by the ROD 4…. From the propagation time of the radiated light, the ROD 4…
unit calculates the exact co-ordinates of the "seen" objects. If the obstacle or person is
located within a defined area, a stop function is executed. In this case, the semiconductor
switch outputs are switched off within the system reaction time. The stop function is automatically reset once the detection area is clear or upon acknowledgement, depending on the
operating mode.
The ROD 4… can detect persons or objects with diameters greater than 20mm at a distance
of up to 4.0m, even when the surface of the given object is dark. Larger objects are detected
at distances of up to 50m.

Operating principle
The working range of the ROD 4… (190°) is divided into 0.36° angular segments.
0.36°
Working range
Figure 3.2: Working range and angular resolution
Bundled light pulses are generated by a laser diode with coupled transmission optics. These
light pulses are reflected by a rotating mirror in such a way that a light pulse is emitted every
40ms in all angular segments (scanning rate: 25scans/s). If the light pulse is incident upon
an object or person, it is reflected and subsequently detected and analysed by the ROD 4….

Description
Figure 3.3: Operating principle
The ROD 4… unit works on the principle of pulse propagation time measurement. The light
pulse propagation time is a direct measurement of the distance to the object.
Combination of hardware and software
The ROD 4… can be programmed using the supplied software. In addition to the device
configuration, the software can also be used to adapt the detection area pairs to the given
application and to save the same in the ROD 4….
The image of the surroundings generated during the scan process is compared with the
specified detection area contours. If an object or person violates a detection area for a least
one scan (40ms), a corresponding, user-specific reaction is triggered.
Application examples
The following examples can be considered typical areas of application for the ROD 4….
Side-tracking skate
To prevent damage to the vehicle and the load being transferred, the ROD 4… can be used
for the following tasks:
• Projection control on the left and right sides of the vehicle.
• Objects located in the transportation path must be recognised in time to prevent damage to the vehicle or to the load.
This task is reliably solved using ROD 4….

Mounting location
Mounting
The ROD 4… unit should be mounted so that the area which is to be monitored is covered
by the corresponding sensor safety field.
Attention!
Because of the optical scanning principle, only objects with good reflective properties are
detected directly in front of the sensor window. Physical damage to the sensor (e.g. due to
collision or climbing on) should be prevented by using a protective enclosure.
In order for the ROD 4… to function optimally, it must be mounted in a favourable position.
You should make every effort to observe the following points:

Notice!
Under certain circumstances, a larger measurement inaccuracy can occur with strongly reflective backgrounds such as retro-reflectors (size: 100x100mm).

Mounting dimensions
The ROD 4… can be fastened using the holes on the rear of the device. No mounting kit is
necessary in this case.
It is, however, recommended that the ROD 4… be mounted with the aid of the BT-ROD-4
mounting kit. The advantage of this mounting variant lies in the exchangeability of the
device. The device can, in this way, be removed from the mounting kit and returned at a later
time without readjusting the device.
With the aid of the BT-ROD 4 mounting kit, pitches of maximum 8° downward or upward are
possible. In addition, the mounting kit allows lateral inclinations of up to ±4°.

Connecting the rotoScan ROD 4…
For its electrical supply, the ROD 4… requires a DC voltage of 24V with a power of 10W
plus the load at the outputs. The power supply must be protected using a 2.5A semi-timelag fuse in the switch cabinet.
To configure the scanner, connect control cable (X1) to the power supply and the interface
cable (X2) to the PC or laptop. Before commissioning the system, please check the pin
assignments, the wiring, the supply voltage and the safeguarding. In spite of the scanner's
robust housing and fittings, which include various internal safety mechanisms, damages
resulting from misconnection remain possible.

• Loosely position the button at the intended position.
• Switch on the voltage supply of the ROD 4… which has been configured for the application.
• Violate the active inner detection area, e.g. by entering it. The violation is indicated by
the following status display (see also Chapter 10.1):
Red LED illuminated:
outputs OSSD1 and OSSD2 disabled
Yellow LED with continuous light:

detection area pairs.
•
•
•
•
•
Detection area pair 1 (X1-4) is the active, primary detection area
The +24VDC supply voltage is applied to detection area pair 2 (X1-6)
In this state both detection area pairs are active
Detection area pair 1 (X1-4) is switched off within one second
In this state detection area pair 2 (X1-6) is active
The following situation would be possible with a DTS application:
The vehicle enters an intersection area while detection area pair 1 is switched on (!). To
prevent objects from coming into danger, detection area pair 2 is switched on before the
curve ("). Detection area pair 1 is switched off within one second. The vehicle travels
around the curve with detection area pair 2 active (#). Afterward, detection area pair 2 is
again switched off and detection area pair 1 activated. The vehicle continues to travel with
detection area pair 1 active ($).
Notice!
The duration for the changeover between detection area pairs is limited to maximum 1s.

Notice!
When configuring the switching on or switching off of detection area pairs, make certain that
the ROD 4… changes over within the response time.
Attention!
If no detection area pair or more than two detection areas are selected by you, ROD 4… reports an error via X1-5 and the corresponding LED in the display field.
"RESTART"
The RESTART input X1-2 has, depending on operating status, several functions:
• Enable restart after a detection area violation.
• New-start after correcting a device error.
• A high signal of at least 3 s and maximum 6 s duration triggers a RESET.
This input must be set from a separate button and may not be connected to the rest of the
control system in order to prevent unintentional enabling of the system. The restart button
must be positioned so that it cannot be activated by a person standing in a safety field.

Notice!
The rotoScan ROD 4 uses two different types of messages at the "Alarm" output:
Warning message - Information for the user indicating that a non-critical device error has
been detected (e.g. window contamination).
Error message - System has detected a critical device error and switches off the semiconductor outputs OSSD1 and OSSD2.
