Description of Adash 3600-MAIN
Adash 3600-MAIN is the main module of the Adash 3600 system. This module performs its own
measurements and evaluation of vibration signals. It also controls other modules of the Adash 3600
system.
Vibration Sensor
The Adash 3600-MAIN module is equipped with one input for the connection of a vibration sensor
with ICP supply. The used sensor must be an accelerometer (acceleration sensor). Its nominal
sensitivity must be programmed during the unit configuration via the Adash 3600 Setup program.
The sensor is connected to the +ICP and -ICP terminal connectors of the Adash 3600-MAIN unit.
If the single channel basic Adash 3600 set is extended with one or more Adash 3600-MPX modules to
achieve a multi-channel set, then the nominal sensitivity must be programmed for each connected
vibration sensor.
The sensors are connected to the +ICP and -ICP inputs of the Adash 3600-MPX module.
Signal Paths
The analogue signal from the vibration sensor (accelerometer) is conditioned prior to its conversion to
the digital form: - by filtration via an adequate frequency filter
- by integration or envelope modulator.
The method of the measured signal conditioning is determined by the selection of a suitable signal
path.
The Adash 3600-MAIN module has four signal paths for vibration measurement:
Signal Result Frequency Signal
path unit band conditioning
-----------------------------------------------------------------------------------------------------
LF [mm/s] 10 – 1000 Hz integration
HF [g] 5 - 16 kHz none
LIN [g] 0.8 Hz – 16 kHz none
ENV [g] 5 - 16 kHz envelope modulator
All parameters, incl. the signal path, are assigned to the measurement during the system configuration
via the Adash 3600 Setup program.
Binary (process) inputs
Some machine works permanently without often changes of working conditions, but works of some
machine is changed quite often. If machine works without changes, then the way of measuring of
vibration is without changes too. But if working condition of the machine is often changed, then way of
