Tabelle 3.1: Device types

The ROD4-3… is an optical, two-dimensional measuring distance sensor. It could also be
referred to as an optical, area radar unit. The device periodically transmits light pulses within
an angular range of 190° via a rotating deflector unit.

If the pulses are incident upon objects or obstacles, the light is reflected and then received
and analysed by the ROD4-3…. From the propagation time of the radiated light and the
current angle of the deflector unit, the ROD4-3… unit calculates the exact coordinates of the
object. If the object or obstacle is located within defined detection fields, 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 field is clear or
upon acknowledgement, depending on the operating mode (software configuration: manual/
automatic).

The ROD4-3… can detect objects with diameters greater than 20mm at a distance of up to

4.0m, even if the surface of the given object is dark. Larger objects are detected in the far
detection field at a distance of up to 50m.

Eight reversible detection field pairs (7 configurable + 1 permanently defined) enable optimal
adaptation to the applications.

Bild 3.1: Measurement ranges and detection fields

The ROD4-3… can be used both on vehicles (mobile object detection for vehicles) as well
as in stationary applications on systems and machines (object detection/measurement). The
long-range and contact-less measurement principle makes the ROD4-3… unit a universally
applicable monitoring device.

3.2 Operating principle

0.36°

Working range

The working range of the ROD4-3… (190°) is divided into 0.36° angular segments (cor­responds to 529 measurement values).

Bild 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, it is reflected and subsequently detected and analysed by the ROD4-3….

Description

Bild 3.3: Operating principle

The ROD4-3… works on the principle of pulse propagation time measurement. The light
pulse propagation time is a direct measurement of the distance to the object.

Reference measurement

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.

Leuze electronic rotoScan ROD4-3... 9

TNT 35/7-24V

Description

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.

Combination of hardware and software

You can configure the ROD4-3… yourself using the supplied RODsoft software. In addition
to the device configuration, the software can also be used to adapt the field pairs to the given
application and to save them in the ROD4-3…

The image of the surroundings generated during the scan process is compared with the
specified detection field contours. If an object violates a detection field for a least one scan
(40ms), a corresponding, user-specific reaction is triggered.

3.3 Special features of the ROD4-3…

• Seven freely configurable near detection fields (up to maximum 30m)

• Seven freely configurable far detection fields (up to maximum 50m)

• Monitoring range up to 190°

• Small construction size (W x D x H: 140mm x 135mm x 155 mm)

•Low weight (2kg)

• Low current consumption (ROD4-30 without heating)

• Two interface types on the X2 SUB-D socket (RS 232 and RS 422)

• Easy-to-use RODsoft configuration software

• Measurement value transmission from distances of up to 65m

• Device plug with configuration memory facilitates simple exchange of devices

3.4 Detection fields / detection field pairs

Eight reversible detection field pairs (7 configurable + 1 permanently defined) enable optimal
adaptation to the applications. A detection field pair is considered to be the combination of
both a near and far detection field. The following designations are used in the RODsoft
configuration software:

Detection field pair x consists of detection_field_near x and detection_field_far x.

The near and far detection fields are represented by different colours in the RODsoft confi­guration software: near = red, far = green.

Detection field pairs 1 … 7 can be freely defined by the user. Detection field pair 8 is perma­nently defined: both detection_field_near 8 as well as detection_field_far 8 are set to zero
here. This means that no area monitoring takes place upon activation of detection field
pair 8.

3.4.1 Changing over between detection field pairs

Attention!

1 or 2 detection field pairs may be simultaneously active and simultaneously monito­red!

Only detection field pairs 1 through 4 are configured

If only detection field pairs 1 through 4 are configured in the RODsoft configuration software,
i.e. it is only possible to start with a field pair between 1 and 4 and it is only possible to chan­geover between a field pair between 1 and 4, then a maximum of 2 detection field pairs may
be simultaneously active and monitored.

Tabelle 3.3: Changeover of the detection field pairs via the control inputs

While changing over between 2 detection field pairs, inadmissible states at the control inputs
are tolerated for a duration of 40ms; after this period the sensor switches to the error state.
The changeover between 2 detection field pairs occurs within a system reaction time of
80ms.

Attention!

Depending on the configuration, output ALARM1, in some cases, also signals device war­nings. This means that a violation of detection_field_far 1 is not uniquely signalled under cer­tain circumstances.
All outputs are switched off during start-up. Outputs ALARM1 and ALARM2 are activated
during configuration.

Notice!

Leuze electronic rotoScan ROD4-3... 13

Description

Operation with 3 detection fields

If only three detection fields are to act on three outputs, only use detection_field_near 1,
detection_field_near 2 and detection_field_far 2 and set the alarm signal type for ALARM1
to "Device warning". The output will then only signal device warnings and is, as a result,
unique.

Operation with 2 detection fields

If only two or fewer independent outputs are needed, 4-field mode is not required and should
be deactivated with the appropriate RODsoft parameter.

Mounting

4 Mounting

The ROD4-3… should be mounted so that the area which is to be monitored is covered by
the corresponding detection 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. If using an enclosure, the entire front cover of the device must,
however, remain unobstructed.

In order for the ROD4-3… to function optimally, it must be mounted in a favourable position.
You should make every effort to observe the following points:

• Position the ROD4-3… in a protected location.

• The mounting location and the electrical supply should be located as close as pos­sible to one another.

• The ROD4-3… is to be mounted so that the area which is to be monitored is comple­tely covered by the detection field.

• The mounting position of the sensor must offer protection from humidity, soiling, as
well as temperatures below 0°C (ROD4-30) or -20 °C (ROD4-36, ROD4-38) and
above 50°C.

• The mounting location is to be selected such that the possibilities for mechanical
damage are minimised. Exposed locations are to be equipped with additional protec­tive guards or loop guards.

• Reinforcements, enclosures, mounting alcoves and other machine elements must not
result in an obstruction in the sensor's field of vision.

• Retro-reflectors or very reflective surfaces, such as certain metals or ceramics, are to
be avoided near the detection fields and at the height of the scanning plane as these
may result in measurement errors.

• To ensure a constant detection height at every point in the detection field, the sensor,
and thus the beam plane, is to be mounted parallel to the reference plane.

• If the sensor is used without start disable or start test with automatic start/restart, a
start warning (optical/acoustic) is to be provided.

• The sensor must not be used as a climbing aid. If there is a risk of this, a suitable, inc­lined (45°) protector is to be mounted.

• If two sensors are used, they should be angled slightly with respect to one another or
be mounted at different heights.

The device dimensions and the reference of the scanning plane to the device edges can be
found in the dimensioned drawing (see figure 9.3 on page 46). Here, the zero point for the
distance measurement is the axis of rotation of the rotating mirror (a in figure 9.3).

5.2 Functions of connection X1

5.2.1 Input circuit

There are two Sub-D connections on the top of the device. At connection X1 with the 15-pin
Sub-D connector, a ready-made cable (KB-ROD4-…) or a cable self-made by the customer
is attached to the solder connections of the connector (connector set KD-ROD4-X1) by
means of soldered connections (see figure 5.5).

Bild 5.2: Inputs of interface X1

Inputs FPS1 … FPS4

With the ROD4-3…, it is possible to work with up to eight detection field pairs. Use inputs
X1-4 (FPS1), X1-6 (FPS2), X1-7 (FPS3) and X1-8 (FPS4) to switch between the detection
field pairs.

Detection field pairs are activated by applying +24VDC (logic: 1) to the appropriate inputs.
If no input is wired, detection field pair 1 is activated.

Notice!

The configuration-dependent changeover of detection field pairs is described in chapter

3.4.1 on page 11.

Attention!

If an inadmissible signal combination (e.g. 1-1-1-1) is applied at inputs FPS1 …FPS4, a
warning is output at output ALARM2 and outputs Fn1/Fn2 are switched off. In addition,

an error is transmitted via the serial interface and stored in the error memory.

off. The vehicle travels around the curve with detection field pair 2 (II) active (). Afterward,
detection field pair 1 (I) is switched back on as well (). Both detection fields (I + II) are
active.
Detection field pair 2 (II) is switched off. The vehicle continues to travel with detection field

5.2.2 Output circuit

The signal outputs are used to control indicator lamps or relays which indicate the device
status. This is switched by a transistor output with open collector set to "active high" (opera­ting voltage).

Bild 5.4: Outputs of interface X1

"Fn1" (X1-11) and "Fn2" (X1-12)

These two semiconductor outputs report violation of the near detection field. X1-11 and
X1-12 = "active high" signals that no object is located in the near detection field. The "low"
state signals the detection of an object in the near detection field (see chapter 3.4 "Detection
fields / detection field pairs").

Attention!

Outputs "Fn1" and "Fn2" are tested alternately. For this purpose, the output signals are re­moved alternately every 20ms for a duration of 100µs. For this reason, the load must de­monstrate lowpass characteristics, limit frequency f

The outputs must not be short-circuited. It is not permissible to connect together the
outputs of two sensors.

g

≤

1kHz.

"ALARM1" (X1-5)

This output is configured via the RODsoft configuration software.

X1-5 = "active high" signals that the device is ready for operation. The "low" output state
signals one of the following states:

1. Possibility: Object detection in the far detection field.

2. Possibility: Device warning, e.g light window contamination, etc.

3. Possibility: Object detection in the far detection field or device warning, e.g. light win-

dow contamination, etc.

4. Possibility: No signalling.

5. Possibility: Device error, e.g. faulty reference measurement.

Notice!

A device error output at alarm output "ALARM2" is also always output at alarm output
"ALARM1", independent of how alarm output "ALARM1" was configured.

26 rotoScan ROD4-3... Leuze electronic

Electrical connection

Notice!

In 4-field mode, output "ALARM1" (X1-5) signals object detection in detection_field_far 1. To
ensure the uniqueness of the signal, you should configure alarm output "ALARM1" so that
only "object detection in the far detection field" is signalled.

"ALARM2" (X1-15)

The "low" output state always signals a device warning or device error, independent of how
output "ALARM1" (X1-5) is configured.

Notice!

A device error output at alarm output "ALARM2" is also always output at alarm output
"ALARM1", independent of how alarm output "ALARM1" was configured.

In 4-field mode, output "ALARM2" (X1-15) signals object detection in detection_field_far 2.

5.2.3 RESTART / resetting the data transmission rate to 57600 baud

The RESTART input X1-2 has, depending on operating status, several functions:

• Release of the restart-disable following object detection in the detection field.

• Release of the start disable following a system start.

The functions are activated by applying +24VDC to input X1-2 of an operationally ready
ROD4-3…. Outputs Fn1 and Fn2 are switched off in the meantime; the display on the sensor
(LED No. 3) illuminates red. A voltage of +24VDC must be applied to the RESTART input
for between 0.12s and 3s.

Restart input X1-2 must be connected to an external, permanently mounted button. X1-2
must not be connected to the rest of the control as, under certain conditions, the application
of a restart pulse could result in an unintended release.

Hardware reset/resetting the data transmission rate to 57600 baud

For this purpose, the ROD4-3… must first be de-energised. By applying +24 VDC for a
duration of 2 … 4s at input X1-2 during the power-on procedure, the data transmission

rate of the RS 232/RS 422 is reset to 57600 baud.

Attention!

Do not interrupt the supply voltage during this reset procedure under any circumstances!

Prematurely interrupting the reset procedure for resetting the data transmission rate can put
the ROD4-3… in an irreversible error state which can only be corrected by the manufacturer!

5.3 Functions of connection X2

At connection X2 (9-pin Sub-D socket), either an RS 232 or 422 interface is available. It is
used to

• configure the ROD4-3…,

• transfer measurement data during scanner operation.

• analyse the coordinates during the configuration
(e.g. for DTS applications).

• diagnose errors and perform troubleshooting.

By default, the connector housing for the X2 9-pin Sub-D connection is delivered with a PG
dummy cable gland. If the connection is not used, this connector housing ensures protection
class IP 65.

We recommend using the prefabricated cable KB-ROD4PC-… (accessory) for configuring
the ROD4-3… For information on fabricating cables yourself, please proceed according to
chapter 5.4.2. After configuring, remount the connector housing with the PG dummy cable
gland.

5.4 Connection

5.4.1 Electrical supply

The ROD4-3… requires a DC voltage of +24 VDC for its electrical supply. The power
consumption is

• for the ROD4-30 (without heating) max. 8W

• for the ROD4-36 and ROD4-38(with heating) max. 50W

plus the load at the outputs (max. 20W).

The power supply must be fed in via an external fuse (e.g. in a switch cabinet) 2.5 A semi
time-lag (ROD4-30) or 4A semi time-lag (ROD4-36, ROD4-38). Furthermore, upstream of
the safeguarding, a constant current of 2.5 A or 4A, respectively, is to be provided to ensure
that the fuse can be tripped in the event of failure.

5.4.2 Fabricating the cable on the sensor side

The delivery contents include three connector housings with screwed cable gland. Two are
required for holding the 9-pin SUB-D-connector and the 15-pin SUB-D-socket (PC and
control cable). One housing serves to protect interface X2 if no data communication is
desired with the PC.

The cable screw fittings can be used with cable diameters from 6.5mm to 10.5mm.

Attention!

Please note that the connector housing of the control cable must be securely screwed to in­terface X1, and the connector housing of cable X2, or the X2 dummy cap (without cable),
must be securely screwed to the ROD4-3… Corresponding threaded pins can be found on
the top side of the sensor housing.

If one of the two connector housings is missing, the ROD4-3… no longer meets protection
class IP 65. The connector assignments can be found in chapter 5.1.

5.4.3 Structure of the connector

Each connector housing consists of the following individual parts:

• Housing with sealing ring and locating pins.

• Cable screw fittings (M16) with dummy plugs.

• Sub-D 9-pin plug or Sub-D 15-pin socket, each with solder connection

Notice!

Information on using the config. connector at connection X1 can be found in chapter 6.3.

TNT 35/7-24V

Electrical connection

5.4.4 Points to be observed when fabricating and laying the cable

• The core cross section of the individual cable strands for connection X1 must be
at least 0.5 mm

• Select a cable outer diameter between 6.5mm and 10 mm.

• Maximum length of the cable for connection X1: 50m.

• Maximum length of the cable for connection X2: 10m (for RS 232).

• Maximum length of the cable for connection X2: 50m (for RS 422, twisted pair).

•Use shielded cable.

• On the switching cabinet side of the system, the cable shielding must only be
connected to PE.

• The cables must not be laid unsecured.

Sensor control cables must not be laid bunched together parallel to the power supply lines
for machines. Inductive interference factors related to high-current-carrying motors are
reduced in this way. Furthermore, the cables are to be routed in such a way that no damage
(e.g. due to crushing) can occur.

As an option, sensor-side prefabricated cables are available in various lengths and for both
interfaces.

With this connection example, the restart-disable is realised by means of the command
device "WA" connected at the RESTART input (X1-2). The device must, in this case, be
configured with the software in such a way that the operating mode "with restart-disable" is

In this example, a detection field changeover between up to 8 detection field contours is
possible via inputs X1-4 (FPS1), X1-6 (FPS2), X1-7 (FPS3) and X1-8 (FPS4) (one near and
one far contour for each). The restart-disable and contactor monitoring are realised via the
RESTART input.

The ROD4-3… is operated in this case in the operating mode "with restart-disable". The
currently active, violated detection field is released by the command device "WA". The relays
K1 and K2 used here have overlapping contacts (make before break) and are operated
directly at the two secure semiconductor outputs Fn1 (X1-11) and Fn2 (X1-12).

6.3 Device configuration with ext. configuration memory / device exchange

The optional connection cable with configuration memory is used for supplemental, perma­nent storage (backup) of the ROD4-3… device configuration in a memory module
(EEPROM) which is integrated in the connector housing.

The ROD4-3… can be connected via the standard X1 connection cable or the connection
cable with integrated configuration memory (see chapter 8.2 "Accessories"). The cable with
configuration memory has the same assignments as the standard connection cable.

If the cable with configuration memory is used, note the position of the slide switch which is
integrated in the connector.

LR

1X

Bild 6.2: Switch in the config. connector

The switch position (see figure 6.2) defines how the configuration memory functions:

• Position "1" - left: the ROD4-3… loads the configuration stored in the configura-

tion memory of the cable when the device is switched on
(standard setting).

• Position "X" - right: the configuration memory of the cable loads the configuration

stored in the ROD4-3… when the device is switched on.

Notice!

The default position of the slide switch is position "1". Position "X" is only necessary in ex­ceptional cases; this is used to copy the sensor configuration to the cable.

TNT 35/7-24V

When the device is switched on, a check is performed to determine whether the configura­tion in the sensor matches that in the configuration memory. If this is the case, the sensor
starts up as usual.

If the configurations do not match, then, depending on the position of the switch in the
connector, the configuration is either transferred from the configuration memory to the
ROD4-3… or vice versa.

Successful transfer is signalled by brief flashing of the two yellow LEDs 2 and 5 on the
ROD4-3…. The configurations stored in the configuration memory and in the ROD4-3… now
match. Afterward, the sensor starts up again as usual.

Commissioning

Notice!

The configuration memory of a ROD4-3… is incompatible with that of a ROD4…/ROD4-2…
and, after used once, cannot be used in the respective device of the other type.

Using the external configuration memory / exchanging devices

If you configure the ROD4-3… with the RODsoft software and save the configuration in the
ROD4-3…, the old configuration in the configuration memory is set to "invalid" and the new
configuration is automatically loaded in the configuration memory of the connection cable
the next time the sensor is started.

In the event of a device failure, disconnect the defective ROD4-3… from power, install the
replacement device and switch the operating voltage back on. The configuration saved in
the configuration memory is now transferred to the new device as described above.

Notice!

You can also use the connection cable with configuration memory to load the same configu­ration in several ROD4-3… devices without having to connect a PC/notebook.

6.4 Screwing down and aligning the device

The ROD4-3… is to be mounted and aligned as described in chapter 4.

6.5 Switching on the device

Once the device is installed, the required device parameters set and the detection fields
defined, the ROD4-3… can be put into operation.

After you have switched on the voltage supply for the ROD4-3…, the red LED illuminates at
first. After the red LED switches off (for free near detection field only), the ROD4-3… is
ready.

8.2.2 BT ROD4 mounting system

The ROD4-3… 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 ROD4-3… be mounted with the aid of the
BT ROD4 mounting system. The advantage of this mounting variant lies in the exchangea­bility of the device. The device can, in this way, be removed from the mounting system and
returned at a later time without readjusting the device.

With the aid of the BT-ROD4 mounting system, pitches of maximum 8° downward or upward
are possible. In addition, the mounting kit allows lateral inclinations of up to ± 4°.

Alarm output ALARM1

Semiconductor output which signals a device warning and error and/or occupancy of
a detection field. The function can be selected in RODsoft via the "alarm signal type".
The output is at pin 5 of interface X1 and is designated in the ROD4 handbook as
ALARM.

Alarm output ALARM2

Semiconductor output which signals a device warning and error.
The output is at pin 15 of interface X1 and is designated in the ROD4 handbook as
WARN.

Start disable

Following device start-up, the restart button must be actuated in order to activate the
outputs.

Start-up test

Following device start-up, the near detection fields must be clear after the start-up
delay period has passed; the outputs are switched off. To activate the outputs, at least
one near detection field must be occupied and then again be cleared.

Start-up delay

Configurable time which must pass before a permanently clear near detection field
activates the corresponding switching output. The start-up delay for far detection
fields is permanently set to 80 ms.

Response time

Time which must pass before a permanent detection field occupancy switches off the
corresponding switching output (separately configurable for near and far detection
fields).

Output start-stop segment, output resolution

Used to configure the measurement value transmission at serial interface X2. The
configuration is made in multiples of 0.36°. A detection range of 180° corresponds to
a start segment of 14*0.36 ° and a stop segment of 514*0.36°. If the output resolution
is > 1*0.36°, the minimum value within the resolution interval is transferred/displayed.
Notice: Monitoring of the detection fields also occurs outside of the configured trans­mission range.

This parameter is permanently stored and is calculated from the maximum radius of
the detection field. Objects are detected if at least the minimum number of consecu­tive scanning beams (multiple of 0.36°) is incident on an object.

Rotational frequency of the scanner deflection mirror = 25Hz.

This parameter can be changed. If the value for the sector size is > 1, objects are
detected if the minimum number of consecutive scanning beams (multiple of 0.36°) is
incident on an object. If the sector size is > 1, the entry for minimum object size is
immaterial.

Serial interface baud rate

Used to configure the transmission rate (9.6 … 687.5 kBit/s) at serial interface X2 of
the sensor. The baud rate is continuously changed in the sensor.

Important notice:
If the baud rate is changed, a PC cannot initially be connected to the sensor via ROD­soft. This must first be adjusted in RODsoft with the Settings –> PC configuration –
> Interface menu command (max. 115200Baud at RS 232). We recommend working
with the factory setting of 57600 Bd.

If the baud rate at X2 is set to a value higher than 115200Baud, a connection is no
longer possible with RODsoft via the RS 232. Resetting to 57600 Bd can then only be
performed via an external connection at pin X1-2 (see chapter 5.2.3 "RESTART /
resetting the data transmission rate to 57600 baud").

Dust suppression

With the introduction of the new ROD4-3… models, considerably more effective dust
suppression was implemented in the devices. With activated dust suppression
(recommended), sensor availability is significantly increased in the event of small par­ticles in the air, such as insects. This also maximises the time which may pass before
cleaning of the front cover becomes necessary.

Dust suppression is implemented globally, i.e. it is used in all detection fields. In the
RODsoft configuration software, 3 parameters determine the function of the dust sup­pression (factory setting: activated):

• the object size (factory setting: 70mm)

• the object speed (factory setting: 1600mm/s)

• the response time (factory setting: 80ms)

Appendix

Object size

This dust suppression parameter defines the maximum size up to which interfering
objects (e.g. particles in the air) should not be detected. Values that are too large pre­vent object detection. Values that are too small increase the sensitivity to interfering
objects. The 'Automatic' setting results in less efficient dust suppression.

Object speed

The object speed specifies the maximum speed of the objects that are to be detected;
if necessary, the speed of the sensor itself is to be taken into account. Values that are
too small prevent object detection. Values that are too large and the value '0 mm/s'
increase the sensitivity to interfering objects.

Comment:

Speed refers not only to the speed at which an object moves toward the sensor
(speed component v
which objects may move in the detection field (speed components v
figure 11.1). As area scanning occurs in the XY plane, speed component v
be detected and evaluated. The maximum object speed can be best optimised

in figure 11.1); it generally refers to the maximum speed with

Response time

Another important parameter is the response time. The longer the selected response
time, the more calculating time is available for the dust-suppression algorithm and,
thus, the more powerful the dust suppression. With a response time < 80ms, only the
object size is evaluated.

Dust suppression is more efficient the:

• greater the selected object size

• lower the selected object speed

• longer the response time

It is a good idea to optimise the values preset ex works (object size: 70mm, object
speed: 1600mm/s, response time: 80ms) for the respective application through
practical tests.

Notice!

Compatibility mode for old ROD4/ROD4-2… models:

•Object size ’automatic’

•Object speed: 0mm/s

Config. connector:If a ConfigPlug with ROD4-3x configuration (with new dust sup-

pression) is plugged into a ROD4/4-2x, the configuration is ac­cepted, but the old dust suppression used!

RODsoft: If a ROD4-3x configuration with new dust suppression is loaded

from a file while a ROD4 or ROD4-2x is plugged in, the new dust
suppression parameters are not displayed. The sensor uses the old
dust suppression following the transfer. The ROD4-3x configuration
becomes a ROD4-2x compatible configuration.

A ROD4-3x configuration can also be loaded if a ROD4/4-2x was
selected. The new dust suppression parameters are not displayed
in this case. The scanner uses the old dust suppression following
the transfer.

Restart

Determines how switching outputs are switched following object detection in a near
detection field in the event of subsequent non-occupancy.

• Manual restart: The restart button must be actuated and start disable must be
active.

• Automatic restart: Following a start-up delay, the outputs are activated.

Angular resolution

Smallest technically possible resolution of the sensor in angular degrees.
