2-6-2 Operation Test

1. Turn ON the power supply unit of this device.
2. Check that the fault indicator (yellow) of ST4-C11 or the fault display (red)
of ST4-C12EX is OFF.
● In case the following error occurs, refer to "Chapter 5 Troubleshooting,"
and report the symptoms to the maintenance in charge.
• When using ST4-C11: The fault indicator (yellow) lights up or blinks
• When using ST4-C12EX: An error is indicated on the fault display (red).
3. When using ST4-A□V, turn the emission amount adjuster on the emitter of
ST4-A□V to the position of MAX. side.
4. Check that ST4-A□ is in the light beam received condition.
5. Check that the beam interruption indicators (red) on the emitter and re-
ceiver of ST4-A□ light up by interrupting the light beam between the emitter
and the receiver of ST4-A□ by hand, etc. Also, check that the control output
indicator (green) on the controller is OFF.
● In case that even if the light beam between the emitter and the receiver of
ST4-A□ is interrupted, the beam interruption indicator (red) on the emit-
ter / receiver on ST4-A□ does not light up, or the control output indicator
(green) on the controller does not turn OFF, refer to "Chapter 5 Trouble-
shooting" and report the symptoms to the maintenance in charge.
<Reference>
If the indicators show reception of the light beam even though the beam is interrupted
by hand, etc., check whether there is any reflective object or extraneous light near
this device or not.

Emission amount adjuster
The emission amount adjuster of ST4-A□V is used to reduce the beam
emission from ST4-A□V, and prevent the influence against other sensors.
Do not use the emission amount adjuster of ST4-A□V in order to
prevent the reflective surfaces.
If it is used in such purpose and adjust the emission amount ad-
juster to the MAX. side, the emission amount will increase and this
may affect the sensing performance. Hence the sensor will be in
undetectable state, resulting in death or serious injury.
To prevent reflective surfaces, refer to "2-3-2 Influence of Reflective Surfaces."
