Basic
The Basic and Basic+ gas detection units are used for monitoring and warning of hazardous gas concentrations. They can be used for detecting commonly used refrigerants.The Basic and Basic+ gas detection units are intended to be connected to a central system like Gas Detection Controller Unit, or a PLC, by either Analog or RS485 open Modbus communications. The central system converts the alarm signal from the Basic unit to activation of alarm devices.The gas detection units come with a factory default, 2-step alarm set-up ready for use. The integrated software enables the user to configure two individual alarm ranges. Alarm 1, a pre-alarm indicating the gas level has passed a predefined threshold 1, and - if the gas level passes predefined threshold 2 - the final alarm 2.
Features and benefits
- Digital, factory configured and pre-calibrated gas detectors for plug-and-play installation (no adjustment required)
- Easy configuration via intuitive user-interface; helps simplify operator handling and minimize risk of operational, settings and calibration errors
- Flexible connection - by either Analog or RS485 open Modbus communications
- Fieldbus wiring - connect and power up to 96 sensors, wire length max. 900 meter per segment; expansion modules permit additional segments
- Automatic self-diagnostics to ensure correct communication and operation
- Sensor seal cap to prevent premature exposure during installation
- Digital user interface ensures higher sensor accuracy and reduced risk of false alarms due to temperature compensated sensors
- Password protected alarm settings allowing authorized access only
- LED status signals and alarms along with Buzzer & Light option for local audio and visual alarms (Basic+)
- On-board acknowledge button to reset alarms and to verify the that no gas leaks are present
