C – DRC Tab
If a suitable DIN Rail DRC is found, the DRC can be configured here:
•
ModBus address saved in the DRC
•
Baud rate between PC and DRC
•
Calibration of the 4 ... 20 mA output
•
ModBus addresses of any sensors
The sensors are registered with their ModBus addresses in fields Sensor #1, #2, #3.
If a zero is entered, the sensor is not scanned.
5. Maintenance
Maintenance work is restricted to cleaning any accumulated particles off the probe and the insulation
section using a cloth or dry and clean pressured air.
Max pressure is 80 Pa for standard version and
200 Pa for EX version.
Grid on both end can be removed using the proper tools to facilitate the cleaning process.
Attention: On EX version, DO NOT remove the grid on fan side.
This is designed to prevent accumulated material resulting in bridge formation against the earthed
environment since this has a significantly adverse effect on the measurement. The other aim is to
prevent the probe becoming encased with accumulated material.
No maintenance work is required in the sensor housing or on the field electronics. For any other
maintenance, please contact ENVEA Process first and follow our instructions.
