Output Configurations
A label on the outside of the sensor lid shows the configuration of the outputs at the
time of product delivery. The sensors/controllers are supplied from the factory (unless
otherwise ordered) with 0...10VDC linear outputs for Out(1) and OUT2. OUT4 is an
open collector output (see
Table II
). If different output configurations are needed for
the application, these have to be reconfigured before the unit is powered up. Default
values are 0-10 V.

Jumper top position provides 0Vdc or 0mA start point for Out(1), OUT2
(0-20mA or 0-10V).
Jumper bottom position provides 2Vdc or 4mA start point for Out(1), OUT2
(4-20mA or 2-10V).

Option Network Adapter for Connection to RS-485-Network
The network adapter to RS-485-network can be mounted on the PCB.
The green
LED flashes every time the adapter answers calls from the network master.
The adapter is put on the UART connector with all five pins connected
. All five
pins of the UART must be connected. The adapter should be mounted with the RS-
485 terminal facing the other terminals and the LED facing the display.
