L
1
= Distance between the inner sensors (placement symmetrical in relation the ESPE’s
light beams) [m]
v = Velocity of the material (e.g. of the conveyor belt) [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 = Total muting time set [s]
(see section 6.3.2 “Monitoring of the total muting time” on page 51)
L
2
= Distance between the outer sensors (placement symmetrical in relation the ESPE’s
light beams) [m]
L
3
= Length of the material on the conveyor [m]
The material can flow in both directions.
The direction can also be defined as fixed:
– Using the additional signal C1: The signal C1 must always be activated, before both
muting sensors in the first sensor pair (e.g. A1 and A2) are active (see section
“Additional signal C1” on page 49).
– Using the Direction detection function that can be configured in software (page 55ff.).
All types of sensor can be used in this placement.
You can usefully increase the protection against manipulation and safety using the
following configurable functions:
– Sensor test, see page 50 ff.
– Concurrence monitoring, see page 51 ff.
– Monitoring of the total muting time, see page 51 ff.
– End of muting by ESPE, see page 53 ff.
– Sequence monitoring, see page 55 ff.
