KEYENCE SL-V Series - Manual (Page 6)

6 SL-V-IM-E
 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 display is the same for the transmitter and the 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 display is the same for the transmitter and the
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-V detects an error, the OSSD keeps the OFF-state (Lockout condition). Bar LEDs 1
through 5 indicate the cause of the problem and the center indicator blinks in red.
Additionally, the number of pulses output from state information output 2 indicates the cause of
the problem. In order to terminate the lockout condition, you must perform the reset operation
(reset input) or restore the power to the SL-V after removing the cause of that problem.
Bar LED indicators and the identified number of pulses on state information output 2
When using multiple SL-Vs in series, the SL-V which triggers the lockout condition will indicate using
Bar LEDs 1-3 while the other SL-Vs will only use Bar LED 1.
*1 Blinking cycle of each indicator and the pulse output time of state information output may be longer.
*2 All indicators on the transmitter may turn OFF.
*3 This error occurs only when it is set that the muting lamp error causes lock out condition.

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.

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.
3
