6 Connecting the logger and installing it on-site
6.1 Connecting sensors to the logger
Depending on its configuration, the following peripheral and measuring devices can be
connected to a logger:
•
up to 4 sensors can be attached and the data can be logged (e.g. pressure, flow)
•
up to 2 alarm-triggering devices (e.g. a light barrier) can be connected to the
switching inputs
•
up to 2 devices (e.g. signal lamp, pump) can be connected to the switching outputs
and can be triggered in the case of an alarm
•
one hose can be directly connected to the internal pressure sensors
Depending on the type of sensors / alarm devices connected, the appropriate parameter
values have to be provided to the logger using the
SebaDataView-3 software. Please
refer to the according chapter in order to get a detailed description of the necessary
configuration steps (see page 51).
External sensors connected cannot be supplied by the data logger. They need a
separate power supply.
6.1.1 Fixed channel allocations
The internal pressure sensors P1 and P2 are always linked to measuring channel
1 and 3. If your logger is equipped with internal pressure sensors, the respective
channels are in use and must not be connected to external sensors.
Due to the internal wiring of the logger, current loops can only be connected to the
channels 2 and 4.
Corresponding to these conventions, the following channel allocations apply:
Channel 1 Channel 2 Channel 3 Channel 4
Internal pressure sensor P1
X
Internal pressure sensor P2 X
First current loop
X
Second current loop X
Please pay attention to this assignment both when connecting sensors as well as when
selecting the measuring channels when programming the logger.
