3.1
Mounting and alignment
An optical data transmission system, consisting of 2 ISD 300 devices, involves mounting each of the
devices on mutually opposing, plane-parallel, flat and usually vertical walls with unobstructed view of
the opposing ISD 300.
Make certain that, at the minimum operating distance Amin the optical axes of the devices are aligned
with one another within ± Amin • 0.01 to ensure that the transmission/reception beams of the two devices lie within the opening angle. This also applies for rotary transmission.
Note
The opening angle (angle of radiation) of the optics is ± 0.5 ° to the optical axis! The horizontal and vertical adjustment angles of the fine alignment with the adjustment screws is
± 6 ° for each. The optical transmission path between the ISD 300 should not be interrupted.
If interruptions cannot be avoided, be sure to read the notice in chapter 5.4.
Therefore, pay close attention when selecting a suitable mounting location!
Attention!
When laying out a mobile arrangement for a ISD 300, pay particular attention that the alignment of the devices relative to one another remains unchanged over the transmission path.
The transmission can be interrupted by jolts, vibrations or inclination of the mobile device
due to irregularities in the floor or path.
Ensure adequate track stability.

Arrangement of adjacent transmission systems
To prevent mutual interference of adjacent transmission systems, the following measures should be
taken in addition to exact alignment:
• With a frequency-offset arrangement, the distance between two parallel transmission paths must
not be less 500 mm.
• With arrangements using identical frequencies, the distance between two parallel transmission
paths must be at least 500 mm + tan (0.5°) x sensing distance.

Electrical connection
Attention!
Connection of the device and maintenance work while under voltage must only be carried
out by a qualified electrician.
If faults cannot be corrected, the device should be removed from operation and protected
against possible use.
Before connecting the device, be sure that the supply voltage agrees with the value printed
on the nameplate.
The power supply unit used to power the ISD 300 must have protected electrical separation
by way of a safety transformer with double insulation according to EN 60742 (equivalent
IEC 60742).
Be sure that the earthing conductor is connected correctly. Error-free operation is guaranteed only when the device is properly earthed.
Described in this section is the electrical connection of the supply voltage, the input and the output.
These connections and their functions are identical for all device variants.
The connection of the respective bus system is described in the following chapters.
To establish the electrical connections, you must first remove the red housing top with the optics. To
do this, loosen the three housing hex screws. The housing top is now only electrically connected to
the base by means of a connector. Carefully pull the housing top straight forward without skewing.

3.3.1 Supply voltage
Connect the supply voltage, including the earth lead, to the spring terminals labelled Vin, GND and
PE (see figure 3.4).
Note
The connection terminals Vin, GND and PE are provided twice to simplify wiring through the
supply voltage to other devices.
The earth lead can alternatively be connected at the screw terminal in the housing base
(max. core diameter 2.5 mm2)
If you would like to wire through the supply voltage, you should replace the filler plugs on the
right side of the housing base with an M16 x 1.5 screwed cable gland and guide the continuing supply voltage cable through this gland. In this way the housing seal is ensured (Protection Class IP 65).
The housing top can be removed and replaced while under voltage.

4.2.1 Baud rate conversion
Through the use of an optical transmission system, the bus is divided into two segments. Different
baud rates can be used in the physically separated segments. The ISD 300s then function as baud
rate converters. During baud rate conversion, it must be ensured that the bandwidth of the segment
with the lower baud rate is adequate for processing the incoming data.
4.2.2 Sorting (switch S4.1)
With the aid of switch S4.1, sorting of the internal memory can be activated and deactivated. If sorting
is deactivated (switch S4.1 = OFF), CAN frames are handled according to the FIFO principle (First-InFirst-Out).
If sorting is active (switch S4.1 = ON), CAN frames are sorted according to their priority. The messages with the highest priority in memory are processed first.
4.2.3 Signal delay
The typical delay of a message from one optical data transmitter to the opposing optical data transmitter is (calculated with 10% stuffing bits):
Number of bits in the telegram x 1.1 x ( 0.5µs + TBit ) + 45µs
Note!
The maximum delay is dependent on various factors (bus loading, history, message
priority, ... ).
TNT 35/7-24V
Attention!
Due to the delay of the messages, it is possible, for example, that the initialisation time
(starting up the system) increases with CANopen.

Changing the operating mode
AUT –> MAN Press the operating mode button for more than 2 seconds.
Only the device on which the button was pressed switches to the “Manual” operating
mode (MAN LED illuminates).
MAN –> ADJ Press the operating mode button on one of the two devices.
Both devices switch to the “Adjust” operating mode (both ADJ LEDs illuminate) when
both were previously in the “Manual” operating mode.
MAN –> AUT Press the operating mode button for more than 2 seconds.
Only the device on which the button was pressed switches to the “Automatic” operating
mode (AUT LED illuminates).
Note!
To switch to the “Adjust” (ADJ) operating mode, both devices in a transmission path must
first be in the “Manual” (MAN) operating mode. It is not possible to switch directly from the
“Automatic” to the “Adjust” operating mode or vice versa.
5.3
Initial commissioning
5.3.1 Switch on device / function check
After applying the operating voltage, the ISD 300 first performs a self-test. If the self-test is successfully completed, the PWR or UL LED illuminates continuously and the ISD 300 switches to the “Automatic” operating mode. If the connection to the opposing device exists, data can be transmitted
immediately.

Operating Instruction ISD 300

TNT 35/7-24V
ADJ –> MAN Press the operating mode button on one of the two devices.
Both devices switch to the “Manual” operating mode (both MAN LEDs illuminate).
Commissioning / Operation (all device models)
If the PWR or UL LED flashes after switching on, there are two possible causes: either a hardware
error has occurred or the transmitter/receiver unit has switched off via the switching input IN.
If the PWR or UL LED remains off after switching on, there is either no voltage supply present (check
connections and voltage) or a hardware error has occurred.
5.3.2 Fine adjustment
If you have mounted and switched on the two ISD 300s of a given optical transmission path and they
are both in the “Automatic” operating mode, you can perform the fine adjustment of the devices relative to one another with the aid of the three alignment screws.
Note!
Note that “alignment” refers to the transmitter beam being positioned as accurately as possible on the opposing receiver.
At the maximum sensing distance, the bar graph does not show end-scale deflection even
with optimal alignment!
The ISD 300 is fast and easy to adjust finely. The optimisation of the alignment between the two
devices of one transmission path can be performed by just one person. Use the following descriptive
steps as a set of numbered instructions:
1.
2.
3.
4.

Both devices are located close to one another (> 1 m). Ideally, the bar graphs of both devices
display maximum end-scale deflection.
Switch both devices to “Manual” (MAN) by pressing the button for a relatively long time (> 2 s).
Data transmission remains active, only the internal cut-off threshold is changed to the warning
threshold (yellow LEDs).
While in the “Manual” operating mode, move until data transmission of the ISD 300 is interrupted. The devices are not yet optimally aligned with one another.
Briefly press the button to switch both devices to the “Adjust” operating mode (ADJ). Data
transmission remains interrupted.
The devices can now be individually aligned. The result of the alignment can be read directly in
the bar graph.
When both devices are aligned, briefly pressing the button on one of the devices is enough to
switch both back to the “Manual” operating mode (MAN). Data transmission is again active; the
vehicle can continue its path. If data transmission is interrupted again, repeat steps 3 through 6.
If the data transmission and the alignment are OK through the end of the path of motion, switch
both devices back to the “Automatic” (AUT) operating mode by pressing the button for a relatively long time (> 2 s). The optical data transceiver is now ready for operation.

Commissioning / Operation (all device models)
5.4
Operation
In running operation (“Automatic” operating mode) the ISD operates maintenance-free. Only the glass
optics need to be cleaned occasionally in the event of soiling. This can be checked by analysing the
switching output OUT WARN (with the INTERBUS fibre optic cable model, a peripheral error message
is also available). If the output is set, soiling of the ISD 300’s glass optics is often the cause (see chapter 6 “Maintenance”).
It must still be ensured that the light beam is not interrupted at any time.
Attention!
If, during operation of the ISD 300, the light beam is interrupted or one of the two devices is
switched off, the effect of the interruption on the entire network is equivalent to the interruption of a data line!
TNT 35/7-24V
In the event of an interruption (light beam interruption or switched voltage-free), the ISD 300
switches off the network to a non-interacting state. The system reactions in the event of an
interruption are to be defined together with the supplier of the PLC.

Maintenance
Generally, the ISD 300 does not require maintenance.
Care during operation:
It is advisable to clean the transmitter and receiver lenses (optical interface) and housing (heat dissipation) at regular intervals (especially in extreme industrial conditions with dust or humidity).
To do so, use a soft, lint-free cloth with a mild water-soluble detergent, if necessary.
