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 DIP-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 1Æ2 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 1Æ2 .
