2-10. PSDI
To use the F3SG-SR in PSDI mode (initiation of cyclic operation by a presence sensing device),
you must configure an appropriate circuit between the F3SG-SR and the machine. For details
about PSDI, refer to OSHA 1910.217, IEC 61496-1, and other relevant standards and
regulations.
2-10-1. Overview
PSDI (Presence Sensing Device Initiation) is the function that F3SG-SR judges the unblocked/blocked
state of the detection zone and operates the machine cyclically (repeatedly). Operations of two-hand
push button switches are made unnecessary majorly on press machines, so operator’s burden can be
reduced and machine availability can be improved.
The following two types of PSDI can be realized without using controllers.
• Single break
The press machine of manual loading and automatic unloading is restarted in this mode by blocking of
the light curtain and unblocking after that.
• Double break
The press machine of manual loading and manual unloading is restarted in this mode after blocking
and unblocking of the light curtain is repeated twice.
