LCN-SHS
Installation guide
Local Control Network - building controls in perfection
P-connection:
Here you can connect for example, the 4-way binary sensor (LCN-BT4H/-BU4L), the
current sensor (LCN-BS4) and the relay blocks (LCN-R8H/-R4M2H/-R2H. The LCN-
BT4H/BU4L and LCN-BS4 will be detected automatically. The LCN-R8H has to be
activated first with the LCN-P or LCN-PRO .
Notes about the sensor technology:
The module monitors overloads and short circuits (T-, I-, P-port) on its sensor technology.
Should the module be short circuited on its periphery, due to wiring errors, it will switch off
the power supply from the sensor for 4 seconds by itself. If 2 further tests show the same
error, it will switch off for 8s + 30s and a status message will be sent to the bus:
“
module reports overload/short circuit periphery.
”,
apart from that the red LED will flash cyclic, as long as the sensor technology is
switched off.
In this case check the connected sensor technology and the wiring.
The LCN-SHS module stays accessible and operational even after these errors!
