With the Short Protocol, the Measurement Analysis will be limited to the Measure 1. Notice that the
check box remains disabled (greyed) until the binary transmission and one of the following measures
are selected:
Top Beam (darkness or light)
Bottom Beam (darkness or light)
Middle Beam (darkness or light)
Total Beam (darkness or light)
Total Contiguous Beam (darkness or light)
Number of the Transitions (darkness or light)
When the Output Hold option is enabled and for all of the time the HOLD input remains active
(external TEACH-IN), the PNP/NPN and the analogue output are driven with the maximum detected
value of the Top Beam Dark measure. This option is available in the Remote Programming mode only.
The external TEACH-IN input maintains its functionality in the Local Programming mode.
The icon button placed at bottom on the right of the panel enables the function Stop Scanning. It
interrupts or activates the scanning cycle by means of a voltage applied to the TEACH-IN input: 0VDC
scanning interrupted, 24VDC scanning activated.
When the Stop Scanning function is enabled, the button changes to and all the others functions
associated with the TEACH-IN input are inhibited (remember that the TEACH-IN is a multifunction
input).
During the period of time that the scanning cycle remains stopped, the receiver’s outputs (digital and
analogue) maintain the previous state before the interruption. The transmitter indicates the absence of
the synchronism signal instead.
