1.3.1. Fixed blanking
Fixed blanking function partly voids detection zone of a light curtain. Entrance of an object
into the invalid detection zone does not change output status. When the fixed blanking func-
tion is valid, the blanking indicator is lit on a receiver.
[Direction for setting]
1) This function is set with the F39-MC11 setting console.
2) The fixed blanking function is made valid.
3) The blanked beams are selected.
(There are two methods of the selection, teaching and manual.)
Note 1: When a blanked beam gets in the light reception state, the blanking function stops
not only for the light reception beam but also for all beams automatically. After the
power is restored, the fixed blanking function gets available with the previous setting.
Note 2: There is no limit for the number of fixed blanked beams.
Note 3: The fixed blanking function is set invalid when the F3SN is shipped.
Note 4: Series connection
The validity of the fixed blanking depends on the setting of the 1CH sensor, which is
the closest to power supply. Regarding the selection of the blanked beams, the setting
is applied to each channel sensor.
Therefore, when you want to select blanked beams only on 2CH sensor and 3CH
sensor, please set as follows:
- 1CH sensor:
Fixed blanking function = “Valid”, and
Blanked beam is not selected.
- 2CH, 3CH sensor Fixed blanking function = “Valid”, and
Blanked beam are selected.
Note 5: When the fixed blanking function is valid, the “Outermost beam monitoring mode” of
the auxiliary output is not available.
