Electronic sensors for temperature, pressure, humidity, differential pressure, etc. are also
available in the
DL
version. In this case, the supply and signal transmission takes place via
the
DL bus
.
Up to 9 values from external sensors can be read via the data link.
The values of the electronic sensors can be taken from sensor inputs for further control tasks
(adjustment in the SENSOR menu, transfer of values).
E1 --
The external value 1 is deactivated and faded out in the main level.
E1 11
The
front
number indicates the address of the external sensor. This can be set to
between 1 and 8 on the sensor according to its operating instructions.
The
rear
number indicates the index of the sensor value. Since external sensors
can transmit numerous values the value required from the sensor is defined via
the index.
The setting of the address and index can be taken from the respective data sheets.
Due to the relatively high power requirement, the "
bus load"
must be considered:
The controller UVR 63H delivers the maximum bus load 100%. For example, the electronic
sensor FTS4-50
DL
has a bus load of 25%, therefore up to a max. 4 FTS4-50
DL
can be con-
nected to the DL bus. The bus loads of the electronic sensors are listed in the technical data
of the respective sensors.
