Installation & Adjustments
Installation
The light curtain is configured by the PC program ‘Telco Space Scan Terminal’, described in
the following pages. Before using it, check the power supply complies with electrical data.
1 Mount the transmitter (SST) and receiver (SSR) facing each other and correctly aligned.
2
Wire the sensor according to the wiring diagram.
Notice that the pin 2 on the SSR and the pin 3 on SST (blue wires) must be connected
together to a common GND ( — ).
Make sure the SSR output load does not exceed 100 mA.
3 Check for correct wiring before turning power on.
4 When the power on indicator (green LED) on SSR and SST is on, the system is
operating.
5 The position of the receiver and transmitter must not be changed after power-up. The
light curtain is only intended for static applications.
SST Test Input
The transmitter SST can be externally disabled and enabled via the black control wire for test
purposes. When the transmitter is disabled the action of the receiver corresponds to breaking
all beams.
Indicators
SSR Red LED Status indicator
SSR Yellow LED Detection Indicator
SSR & SST Green LED Power on indicator
Troubleshooting
Probable Reason Corrective Action
1. Symptom: Status indicator (Red LED) on SSR is constant on.
SST has no power. Check supply and supply cable to the SST
SST & SSR white, grey and blue wires are
not connected correctly. Connect the wires.
2. Symptom: Output indicator (Yellow LED) on SSR is flashing.
Severe electrical interference. Separate SSR and SST supply cable from high
voltage cables.
Severe ambient light. Swap position of SSR and SST.
Cross talk from another light curtain or
photo sensor Swap position of SSR and SST.
Cross talk from a nearby HF strip light Swap position of SSR and SST or remove the
strip light.
3. Symptom: Digital outputs do not response when IR beams are obstructed.
One or more beams are blocked or the
rails are out of sensing range.
Remove obstruction or reduce the distance
between the rails.
The test input on SST is activated Remove SST pin 4 (black wire) from ground.
Outputs are not configured for simple
detection of obstructions
If needed factory reset the SSR using the
System Information page in the PC program

1. Start by selecting the RS485 Serial Port and Modbus Set Up and select the correct port to communicate with the SS02. If the port number is not known it is possible to press the Get
Com Port Information. This will list all COM Ports used by the PC. (Full Com port details in Win7, WinXP only basic details are shown ). The RS485 BUS ADDRESS is default 127, but
address can be changed in the menu Function -> System Information.
2. Next press Connect and wait a few seconds before the connection is active.

Status Messages:
Status messages are logged and displayed by choosing this menu item.
Each functions associated with each of these menu items will be described in detail the
following.
Functions -> Overview -> General Setup tab
General Setup:
Right side shows the light curtain and the beam pattern. Unbroken or made beams are indicated by green and broken beams by red. The light curtain is in the setup oriented with the cable entry in the
bottom.
Scan Mode. Parallel or Cross beam selection.
On cross beam mode, the number of actual beams are increased from N straight beams to (3*N)-2 beams giving a more dense beam pattern, with larger detection certainty.
If objects are positioned in the centre, or close to the centre, between transmitter and receiver the measurement resolution is increased to the double, i.e. the crossed beam mode adds an additional
virtual beam between each of the straight beams, in total N-1 extra virtual beams. When crossed beam mode is selected the number of beams is increased to (2*N)-1 in total, which therefore also will
be the new maximum of the analogue output. Be aware that objects has to be taken out of the light curtain when switching from parallel beam mode into crossed beam mode when it is in automatic gain
mode. The reason is that the gain of the crossed beams has to be initialised.
Gain Control:
In the Manual Gain it is possible to set the Manual Gain Level (a fixed gain level). In Automatic Gain mode it is possible to set the excess gain level. In both manual and automatic gain is it possible
to set the Hysteresis level. Keep objects out of the light curtain when switching to automatic gain mode or when adjusting the excess gain level, because the initial setting of each beam requires
information about signal strength for an unbroken beam.
Blanking:
It means to deactivate beams resulting one or more areas in the light curtain where the status of the beams are ignored. Blanking can either be setup by writing directly which beams to be blanked in
the text box. Writing ’12-16, 20’ means that all beams starting from beam no 12 and ending with beam no.16, and beam no. 20 are blanked. When the blanking is written, it shall be transferred to the
light curtain pressing the button Write to Light Curtain, whereby it becomes active. Blanked beams are marked blue as seen below.
Beams can also be blanked by simply reading obstructed beams from the light curtain by pressing the button Measure From Light Curtain, whereby the obstructed and now blanked beams will be
written in the text box. It is not necessary to press Write to Light Curtain for activating the blanking.
Smoothing Function (Minimum Size of Coherent Area):
The Smoothing Function tells the SSR to ignore objects which are smaller than a specific size. If the Smoothing Function is set to 3, any object that interrupts 3 or less adjacent beams will be ignored.
Smoothing can be used, e.g., to ignore interference caused by wood chips while sawing a log.
The effect is obtained by a pre-processing of the beams status where all groups of adjacent broken beams with less than or equal to 3 beams are substituted by made beams.
This smoothing function is carried out after the ‘hole detection’ pre-processing.
Signal OK indicator: when the signal level is sufficient for stable operation of the light curtain the Signal OK indicator will be green. If the Signal OK indicator is off, the gain should be increased or
distance between transmitter and receiver should be decreased. The Signal OK indicator will also go out if there is a loss of synchronisation between the SST02 and the SSR02.
