AirSafe 2 is an ambient air dust monitoring device. It is not a safety device. 1.2 Product overview Thousands of electrodynamic sensors from ENVEA Process have proven their worth for measuring dust concentrations in processing systems. AirSafe 2 is a measuring device which can monitor the dust concentration in the ambient air, for example in buildings, production halls, silos, boiler houses and at work stations. -
Page 6: System
1.4 System The AirSafe 2 flow duct measures 500 mm in length and has a diameter of 100 x 100 mm. The integral dust sensor has a 4... 20 mA analog output, a modbus communication port as well as a relay output which switches or trips an alarm if a limit value specified by the customer is exceeded. -

Attention: In case of noisy or possibly damaged fan, please unplug the sensor immediatly from any power source and proceed to cleaning. Contact ENVEA Process or your local dealer in case of need. Please keep the sensor clean from dust accumulation. Inside of air channel can be easily cleaned by removing the grid opposite to the fan. -

4.4 One-Button-Setup 4.4.1 Parameter setup Directly on the sensor the parameter can be changed by using a One-Button-Setup. When Button S1 is pressed all LEDs start blinking on-off simultaneous (1-1-1 to 0-0-0) five times. After this sequence the binary number of the first parameter is lit (0-0-1) for five seconds. -

A – Software connection This software is available for download on our website: https://www.envea.global/solutions/process-optimization/product-software/ Please note, that the COM port attributed to the sensor must be between 1 and 16. When the software start in „direct“ Mode there will be a connection established to the AirSafe 2 at Modbus address #2, ModBus address is selectable. - Page 12 B – System Tab This is where the COM port, Baud rate and sensor address are set: ModBus address for direct sensor communication: 2 • ModBus address for DRC communication: 1 • Communications parameters are also available, as well as language (GER/ENG) and the possibility to save and write sensor parameters into a file.

4.5.1.2 AutoSetup “AutoSetup” starts a search of the alarm value: The sensor searched for the signal level which corresponds to the current dust load. See section sensor manual for a detailed description. 4.5.1.3 Sensor measurement data Dust: the measurement for the dust load ✓... - Page 15 D – Trend Tab The measurement and calculation values of the sensor can be observed here. The sensor’s dust value is always scaled on the left whilst the switch threshold or the relay output, for example, can be visualised on the right. We can show the DUST value on the graph (Dust tick box), the Alarm status (Alarm tick box) and the Threshold level (TRH tick box).

2. Check whether the green LED is flashing or the yellow LED is lit. This indicates a problem with the relay contact. 3. Check whether the red LED flashes during an active measurement. Error code!! If the sensor is still not supplying signals after these checked, contact our agents or ENVEA Process direct. 6.2 Errors Errors can be seen via the software or via LED‘s status. -
