L
1
< 200 mm; Minimum distance between the light beams on the ESPE and the
detection by the muting sensors [m]
v = Velocity of the material (e.g. of the conveyor) [m/s]
t
d
= Input delay of the UE403 or the sens:Control device [s]
(see the operating instructions of the UE403 or sens:Control device)
t
res
= Response time M4000 [s]
(see section 13.1 “Data sheet” on page 115)
t = Muting hold time set [s] (with End of muting by ESPE function activated) or total
muting time set [s]
(see section 6.3.2 “Monitoring of the total muting time” on page 51)
L
2
= Length of the material on the conveyor [m]
L
3
= Maximum distance between C1 and the detection line of the sensor which is closest
to the ESPE [m]
Only material flow out of the hazardous area is possible.
Position the two muting sensors at the side of the hazardous area.
This placement is suitable for through-beam photoelectric switches and photoelectric
reflex switches.
Avoid mutual interference between the sensors.
If you activate the Exit monitoring function, you must either activate the End of muting
by ESPE function of configure the Total muting time.
The functions Direction detection and Sequence monitoring can not be configured.
You can usefully increase the protection against manipulation and safety using the
following configurable functions:
– Sensor test, see page 50ff.
– Concurrence monitoring, see page 51ff.
– Monitoring of the total muting time, see page 51ff.
