■
Start-up after turning on power
The bar LEDs 1 to 4 light up in the following sequence during start-up (approx. 4.5 s). The other indi-
cators are all off. The indicators show the same indication between the transmitter and receiver.
■ During normal operation
●
When the interruption is present in the detection zone (one or more beam axis is
blocked.)
The state of bar LEDs No.1 to No. 5 means as follows.
No. 5
: It lights in red when no interruption is present in the top beam axis. (clear)
No. 2 to No. 4 : It does not light when the interruption is present in either the top or bottom beam
axis (blocked). On the other hand, it lights in red when no interruption is present in
both the top and bottom beam axes (clear) and the interruption is present in any
other beam axis. (blocked)
No. 1 : It lights in red when no interruption is present in the bottom beam axis. (clear)
The indicators show the same indication between the transmitter and receiver.
Indication pattern
●
When no interruption is present in the detection zone
The bar LEDs No.1 to No. 5 means as follows. They indicate the number of beam axes with the
amount of receiving light of 140 % or greater. The indicators show the same indication between
the transmitter and receiver.
Indication pattern
For the definition of the amount of receiving light of 100 %, 100 % means a threshold between OSSD-
ON and OSSD-OFF.
In case of around 100 %, the light curtain easily goes to ON state or OFF state due to environmental or
installation factor, such as dust, pollution, angle, vibration or the like.
●
During lockout condition
If the SL-VHS has detected any kind of irregularity, the OSSD (control output) will lock itself in the
OFF state. When this occurs, bar LEDs 1 through 5 will indicate the source of the problem and the
center display light will blink red.
To end the lockout condition, solve the source problem and send reset output or turn the device
off and then back on again. Try the following measures.
Bar LED indicators
When using multiple SL-Vs in series, the SL-VHS which triggers the lockout condition will indicate
using bar LEDs 1-3 while the other SL-VHS will only use bar LED 1.
*1 Blinking cycle of each indicator output may be longer.
*2 All indicators on the transmitter may turn OFF.

Description
The amount of receiving light for all
beam axes are 100 % or more, but
less than 140 %. This state is not
stable for operation.
The amount of
receiving light for all
beam axes are 100
% or more, and that
of any one beam
axis is 140 % or
more. The amount of
receiving light for all
beam axes are 100
% or more, and that
of any two beam
axes are 140 % or
more.
The amount of
receiving light for
almost all beam
axes are 140 % or
more.

Indicators on the transmitter Indicators on the receiver Error name Cause and corrective action
OSSD
error
• OSSD is short-circuited to 0 V or 24 V of
power supply.
• OSSD are short-circuited to each other.
• Unit cable for transmitter is connected to
receiver ---vice versa.
• OSSD is affected by external noise.
Check the connections.
There is a voltage surge affecting the OSSD
due to an inductive load. Use a load with a
surge absorption function.
Too much current is flowing through the
OSSD. Make sure the load does not
consume more current than the OSSD can
handle.
OSSD is broken. Replace the receiver.
EDM error
There is a welded contact on the external
device. Replace the external device.
• The EDM input is not connected to the
external device correctly.
• When the EDM function is not used, the
EDM input and AUX are not connected
correctly.
Check the wiring for the EDM input.

or continually. Replace the power supply,
increase the power supply capacity, or
prepare the power supply dedicated for the
SL-VHS.
