2.4. Output function
2.4.1. Presence detection
For the presence detection mode, you have to put DIP-switch 7 in "OFF" position. The
output signal for the relay at channel 2 is selected with the help of DIP-switch 8, while a
permanent signal is emitted at relay 1 for channel 1.

2.4.2. Directional detection
(not for all types; see 8. Device categories)
If
DIP-switch 7 is
"ON",
two directional logics will be supported in dependence on D
IP-switch
8.
The directional pulse is mainly used in counting devices, whereas the permanent direction
signal is used for requests in gate- and barrier control units.
In the following, we will explain the function of the directional logic, taking loops 1 and 2 with
direction of motion 1
Æ
2 as an example. The direction signal is emitted by the relay of the
loop that the vehicle crosses first. This means that the signal will be indicated by relay 1 if
the direction of motion is 1
