Self-Diagnosis Function; Interlock Function - Panasonic SF4D Series Instruction Manual

Functions
3-1 Self-Diagnosis Function (Common for all cables)
The device includes a self-diagnosis function.
Self-diagnosis is executed when the power is turned ON and periodically during operation.
If an abnormality is detected, the device is immediately put in the lockout state and the control
output (OSSD 1 / 2) is fixed in the OFF state.
Refer to "Chapter 5 Troubleshooting" to remove the cause of the problem.
3-2 Interlock Function (8-core cable, 12-core cable)
The interlock function prevents the control output (OSSD 1 / 2) from automatically turning ON
when the device is in the light-receiving state.
With manual reset selected and the control output (OSSD 1 / 2) in the OFF state (interlock
state), execute a reset in the light-receiving state to turn ON the control output (OSSD 1 / 2).
Manual reset / automatic reset can be selected by means of the connection of the interlock set-
ting input wire (pale purple) when the power is turned ON.

which provides a clear view of the entire danger zone.
● When using the device with auto-reset, use a safety relay unit or other device to prevent auto-
matic restart of the system after safety output shutoff. (EN 60204-1)
