Warning
: Please pay attention to the signal type of the sensor when connecting the sensor.
Connecting the sensor with the wrong signal type can damage the amplifier and the sensor.
The measured values are issued in digits (16 bit signed integer format) with leading signs (see page
6 in brackets).
If the SI-RS485 is adjusted to a specific sensor, the output value will be stated on the test certificate.
If the SI-RS485 is not adjusted to a specific sensor, the output values are adjusted as stated on page 6.
In this case, the output values are adjusted with a high-precise reference.
The evaluation occurs by the VS3 software which contains following functions:
•
Configuration possibilities for the VS3
•
Storage of sensor-related scaling and adjustment data
•
Display for the presentation of measured data
(actual value, tare value, minimal value and maximal value)
•
Presentation of the measured data in a diagram
•
Storage of measured data in CSV-format (output configurable)
•
Storage of the diagram in BMP-format (output size adjustable)
•
Print-out of the diagram (output size defined)
•
Presentation of the sensor information
The communication protocol is described in document no. 090110, “A flexible command set for digital
sensors and interfaces” which states how to activate the SI-RS485 through own software.
4.2 Safe and Correct Use
Warning
: Observe the correct sensor adjustment.
Consider the correct VS3 configuration.
Choose a significant file identification/prefix when storing measured data.
Fasten housing, ground, connect power supply, protect from splash water and do not pull
the cable.
5 Technical Details
5.1 Configuration of the Connections
There is no maintainable connection inside the SI-RS485 housing. The connection of the power sup-
ply unit occurs on the side of the housing. The sensors and the digital interface can be connected
through sockets as well.
5.2 Adjustment of the Second-Order Low Pass Filter for each Sensor
Channel
5.2.1. Changing via VS3
If a SI-RS485 was connected, the software offers this option in the tab for measurement adjustments.
