Check list (Daily inspection)
Check column
□ 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.
□ 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 opera-
tion, remove its cause and reinspect.
The test rod (SF4C-F□: ø14mm, SF4C-H□: ø25mm) moving 1,600 mm/sec. or less can be detected at
three positions, directly in front of the emitter (A), midway between the emitter and the receiver (B), and di-
rectly in front of the receiver (C) 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 test
rod (SF4C-F□: ø14mm, SF4C-H□: ø25mm) 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 test input / reset input wire (pink) is open
□ (for manual reset: connected to 0V or +V). At this time, the effect of external noise can be inspect-
ed. 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 lamp (cleanliness or brightness etc.)
