-
ing this device without inspection or in an error condition can result in death or serious injury.
Check list (Daily inspection)

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 dangerous parts of the machine.
□
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 / 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 reinspect.
□
It should be possible to detect the test rod (ø25mm for
SF4B-H□C□
or ø45mm for
SF4B-A□C□
)
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) when the test rod is moved at a speed of 1,600mm/sec.
The OSSD indicator (red) of the receiver and the operation indicator (red) of the emitter continue
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 tes-
trod 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 receiver (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 / 2) must turn OFF when the emission halt input / reset input wire (pink)
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 reinspect.
□
Be sure to check the operation of the muting function before its use. Furthermore, check the state
of the muting indicator (cleanliness or brightness, etc.)
