Inspection item
Dangerous parts of the machine cannot be reached without passing through the sensing area
of this device.
Some part of operator’s body remains in the sensing area when operation is done with dan-
gerous parts.
The calculated safety distance has been maintained or exceeded during installation.
There is no damage to the safety guard or protective structure.
There is no defect, fold, or damage in the wiring.
The corresponding connectors have been connected securely.
No dirt or scratches exist on the light emitting surface.
The test rod is not deformed or defective.
The operation indicator (green) of the emitter and the OSSD indicator (green) of the receiver
light up when no object is present in the sensing area. The control output (OSSD 1, OSSD 2)
is in ON status.
At this time, the effect of external noise can be inspected. In case external noise affects the
operation, remove its cause and re-inspect.
The test rod can be detected at three positions, directly in front of the emitter (A), midway
between the emitter and the receiver (B), and directly in front of the receiver (C).
The OSSD indicator (red) of the receiver and the operation indicator (red) of the emitter con-
tinue to light up as long as the test rod is present in the sensing area from (A) to (C).
With the machine in the operating condition, the dangerous parts operate normally when no
object is present in the sensing area.
With the machine in the operating condition, the dangerous parts stop immediately when the
test rod is inserted into the sensing area at any of the three positions, directly in front of the
emitter (A), midway between the emitter and the receiver (B), and directly in front of the re-
ceiver (C).
The dangerous parts remain stopped as long as the test rod is present in the sensing area.
The dangerous parts stop immediately when the power supply of this device is turned OFF.
The control output (OSSD 1, OSSD 2) must turn OFF when the emission halt input / reset
input line is open (for manual reset: connected to 0V, +V). At this time, the effect of external
noise can be inspected. In case external noise affects the operation, remove its cause and
re-inspect.
Be sure to check the operation of the muting function before its use. Furthermore, check the
state of the muting lamp (cleanliness or brightness etc.)
Be sure to inspect the following items prior to operation and confirm that there is no error.
Operating this device without inspection or in an error condition can result in serious injury or
death.
