Technical Specification of Adash 3600-MAIN
Inputs: - 1 for vibration measurement (accelerometer with ICP supply)
- 4 binary for definition of machine state (run, coast down, run up, ...) and for
external trigger
- 1 DC for DC value of operational quantity (power, machine speed,
temperature,...)
Outputs: - 1 analogue AC buffered signal from the vibration sensor (output short-
circuiting will not effect the signal measured by the unit)
- 4 relays with change-over contacts (~250 V / 0.4 A, 100 W):
- OK unit
- OK state (no critical value exceeded)
- Alert limit exceeded
- Danger limit exceeded
- 2 current loops 4 – 20 mA, galvanically separated:
- vibration power by ISO 2372 via signal path LF
- bearings condition measured via the selected signal path HF, LIN,
ENV
Data processing: - vibration power measurement by ISO 2372 - LF (mm/s in 10 – 1000 Hz
band)
- bearings condition measurement
- HF (g in 5 – 16 kHz band)
- LIN (g in 0.8 Hz – 16 kHz band)
- ENV (g envelope analysis - HFE in 5 – 16 kHz band)
- time signal and signal spectrum via LF, HF, LIN and ENV signal paths
Signal conditioning: - integration
- envelope modulation in 5 – 16 kHz band
Sampling frequency: - 4 kHz for vibration power measurement by ISO 2372
- 40 kHz for bearing condition measurement
Limits: - Alert and Danger
(The limits are set up for each measured quantity separately: various limit
values can be set up for various machine operating states defined by binary
channels. Various limit levels can be set up according to the operational
quantity value defined by the level of DC input.)
Trigger: - auto (free run)
- external trigger
Measurement interval: - approx. 750 ms (for measurements of static values only)
Interface: - serial RS-485 for communication between the modules of the set
- serial RS-232 via the Adash 3600-COM module
Protection: - IP20
Temperature range: - -10 °C to +50 °C
Supply: - 5 V / 0.5 A DC
Dimensions: - 106 x 90 x 58 mm
Weight: - 275 g
Mounting: - DIN rail
Unit setting: - using the Adash 3600 Setup program from PC via serial interface RS-232
