Omron F3SG series User Manual page 105

In case configured as Blanking Disable, if an interrupting object gets smaller than the setting value, the
floating blanking function is canceled. That is, the entire detection zone of F3SG-RA works as the
normal detection zone.
If Temporalily Disable Monitoring by Wiring is configured, the monitoring function can be temporarily
disabled during operation by hard wiring of muting input A and muting input B. For details, see below.
If Temporalily Disable Monitoring by Wiring is configured, muting function cannot be used.
 Temporalily Disable Monitoring by External Wiring
If Temporalily Disable Monitoring by Wiring is configured, the floating blanking monitoring function can
be temporarily disabled during operation by hard wiring of muting input A and muting input B of a
receiver.
The blanking monitoring function is disabled for a period of T2 by turning muting input A from OFF to
ON and muting input B from ON to OFF within an input time difference T1 (4s) using a limit switch, etc.
Inputs of muting input A and muting input B must be redundant inputs of different kinds such as a
combination of N.O. contact and N.C. contact types.
(In case of a PNP output photoelectric sensor, use one output as Light-ON and the other as Dark-ON
operation)
The user can use this function only when the F3SG-RA is used as a one segment system and the
function is enabled by the Configuration Tool. The function cannot be enabled when the F3SG-RA is in
the cascade connection.

T1: Muting input limit (fixed to 4 s)
The maximum value of an input time difference between muting input A/B.
Configured as 4 s.
T2: Monitoring Temporarily Disabled Time Limit
A time limit to disable blanking monitoring. When this time period passed, the
blanking monitoring function is enabled, and lockout occurs if the blanked beam is
unblocked. The factory default setting is 10 s (configurable).
T3 Maximum allowable muting signal interruption (fixed to 0.1 s)
Maximum duration of a signal interruption allowed in Muting inputs A and B. This is
set at 0.1 s.
T3 (0.1 s) or less
T1 (4 s) or less
T3 (0.1 s) or less
