4.4 Range reduction
In addition to selecting the suitable transmission channels (see chapter 4.3 „Transmission channel
changeover“), the range reduction also serves to prevent mutual interference of adjacent safety sensors.
Activating the function reduces the light power of the transmitter so that around half of the nominal range
is reached.
Reducing range:
 Wire pin 4 (see chapter 7.1 „Pin assignment transmitter and receiver“).
The wiring of pin 4 determines the transmitting power and thereby the range.
4.5 Scan mode
The safety sensor features three scan modes (see table 4.2). Depending on the operating mode selected
(see table 4.1), a certain scan mode is automatically set.
Table 4.2: Activation and characteristics of the three scan modes of the safety sensor
Faulty function due to incorrect transmission channel!
Select the same transmission channel on the transmitter and corresponding receiver.
WARNING
Impairment of the protective function due to incorrect transmitting power!
The light power emitted from the transmitter is reduced through a single channel and without safety-rele-
vant monitoring.
 Do not use this configuration option for safety purposes.
 Note that the distance to reflective surfaces must always be selected so that no reflection bypass can
occur even at maximum transmitting power. (see chapter 6.1.4 „Minimum distance to reflective
surfaces“)
Only after an interruption of the protective field continues for several consecutive scans are the
OSSDs and thereby the downstream machine switched off. As a result, selecting the scan mode
can increase the availability (tolerance) at the expense of the response time - particularly in the
case of EMC disturbances, light physical shocks, brief protective field violations due to falling ob-
jects and the like.
Activation OSSD behavior Remarks
SingleScan Selection of operat-
ing mode 1, 2 or 3/
FG2
Switch-off directly after
every protective field vio-
lation detected
Fastest scan mode with shortest
response time
DoubleScan Selection of operat-
ing mode 3 / FG1
Switch-off in the case of
protective field violations
in two consecutive scans
Depending on the number of beams in
the protective field, a certain tolerance
time towards malfunctions exists. The
response time doubles compared to
SingleScan mode.
MaxiScan Selection of operat-
ing mode 4 or 6
Switch-off in the case of
protective field violations
in several consecutive
scans
The number of tolerable protective field
violations (MultiScan factor) is deter-
mined by the receiver to be the maxi-
mum possible value depending on the
number of beams, so that the maximum
response time is 99 ms (fixed value).
