• Install light strips
• Perform automatic calibration cycle (see chapter 4.4)
• System is now ready.
The light strips are synchronised via an optical synchronisation beam (state on delivery:
beam 1 - on cable edge).
The state on delivery is defined by
• signal output
1 x switching output over entire measurement field length (black wire, pin 4)
1 x warning output (yellow wire, pin 2)
• switching function
00, 01: light switching,
02, 03: dark switching (inverted to light switching)
• analysis function
00, 02: parallel beam method (only opposing receiver diodes are analysed).
01, 03: parallel/diagonal beam method (opposing as well as the next higher receiver
diodes are analysed).
The VARIO B can be reconfigured for special applications.

Configuration software
The VARIOSoft 3.1 configuration software can be used to change the functionality of the
VARIO B light curtain. The software functions under the Windows® 95/98/2000/NT/XP operating systems.
VARIOSoft 3.1 configuration window:
Configurations can be stored on the hard disk using the File: Save button. Saved configurations can be imported using the File -> Configuration menu item or the File: Load button.
The connected receiver bar can be activated and deactivated using the Power X button.
In general, parameters are changed in the white fields. Changed values are indicated by
italic text with a yellow field background.
Attention!
After entering numeric values, you must confirm the entry with <Return>.
After completing changes to the parameters, this configuration is transferred to the light
curtain system by clicking the Data: PC to VARIO button.
Attention!
Please note that only the data of the column above the button are transferred. These settings are retained even after the system is switched off.
Use the 1 Normal operation button to switch the light curtain to the normal detection state.

Parameters
Synchronisation beam
Specifies the position of the optical synchronisation beam.
Attention!
If the synchronisation beam is interrupted, both switching outputs are activated
automatically!
Input option:
first beam
last beam
Default:
first beam (connector/cable end)
Attention!
If the synchronisation setting is changed, this parameter must also be changed on the transmitter bar! To do this, connect the black pin (pin 4 on the connector) to terminal KL6 of the
VB-Int-232 interface module; the configuration routine is performed in a manner analogous
to that for the receiver bar.
Max defect tolerance
Definition of the maximum tolerable noisy or defective receive signals before the system
switches to fault mode (flashing LEDs).
Attention!
A signal is also marked as defective if it is interrupted for longer than the
set "warning time"!
Input option:
0 to 255
Default:
4
Relative threshold warn
Definition of the signal threshold as a %; if, while in the "non-interruption state", the value
falls below the value set here, soiling is indicated. The setting is made numerically in the
range from 0 … 255, whereby value ’255’ corresponds to 100% of the calibration threshold.
Input option:
0 to 255 (0 … 100%)
Default:
147 (58%)
Warn signal delay [s]
Definition of the response time in s for the warning function.
10
Input option:
0 to 255
Default:
60

Input option:
0 to 255 (0 … 100%)
Default:
85 (33%)
Output hold time [ms]
Artificial extension of the output signal in ms.
Input option:

0:
Complete measurement field length is detection range, warning function is 2nd output.
>2: Warning output becomes switching output for 2nd range.
Attention!
If the synchronisation beam is interrupted, both switching outputs are activated
automatically!
Input option:
0 to 255 (only max. present beams)
Default:
0
Output interface
Assignment of the signal outputs to physical pins.
Input option:
Sig bl / Warn ye
Sig ye / Warn bl
Sig bl / Warn: off
Sig ye / inv Sig: bl
Default:

P_plus_D-analysis
Default:
corresponding to delivery option
Switching output function
Definition of the signal function:
Light switching: Signal active if measurement field is not uninterrupted.
Dark switching: Signal active if measurement field is interrupted (at least 1 beam).
Switching behaviour corresponding to the PNP or NPN signal definitions.
Attention!
Mode Dark switching corresponds to the inverse of the light switching signal!
Input option:
light switching
dark switching
Default:
corresponding to delivery option
Beam settings
Definition of the beams to be ignored (blanking). Beams which are not present are not taken
into account.
Attention!
The synchronisation beam cannot be deactivated!

The transmitter and receiver bars must be aligned with each other with an accuracy of
about 10°.
Do not place any mechanical load on the bars or bend them, etc.
Be careful during horizontal mounting, as liquids may be detected on the front cover
as if they were objects. If they remain there for a long time, they may penetrate the bar
and damage the electronics. Increased risk of soiling.
Protect the cable from being crushed and from exposure to strong electromagnetic
effects.
Strong extraneous light effect (caused for example by strobe lights, direct sunshine)
on the receiver bar should be avoided.
Prevent optical sensors (for example other light curtains, photoelectric sensors) from
affecting each other by positioning them appropriately or blocking them from each
other, etc.
There must be no reflecting surfaces near the light curtain. Otherwise objects may not
be detected due to the reflection.

Bars must only be connected while there is no voltage in the system.
Avoid ground loops; all bars must have the same grounding potential.
A potential difference of 60V between the bar housing and the supply voltage must
not be exceeded.
Insulate unused wires.

Mounting with alignment of the light curtain
Connection of the light curtain cable to the terminals provided for that purpose
Connect the yellow wire of the cable to the bridge to the +24VDC terminal
Keep the monitoring area free, especially beam 1
Turn on the 24VDC supply voltage
Disconnect the bridge between the yellow wire and +24VDC as long as the light curtain is still connected to the supply voltage
=> The upper LED (LED1) at the receiver flashes once indicating that data are being
saved
Check the functionality of the light curtain in the entire monitoring area using an
opaque object.
The calibration (items 3 to 6, yellow wire) is important for adapting the light curtain to the
specific application. You should, therefore, perform the calibration for availability following a
change to the application.
Notice!
Note that the monitoring area, especially beam 1 (the first beam starting from the side of the
connection cable) is free.
