Monitoring or warning of this gas. Triggering of protective measures:<br \/>\n&#8211; Technical: The increase in concentration is counteracted (fan; shutdowns&#8230;.).<br \/>\n&#8211; Organizational: Visual and acoustic messages.<\/p>\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"text-align: left;\">\n<p>The <strong>ExDetector HC200<\/strong> sensor can be programmed in two operating modes:<\/p>\n<p>\u25cf <strong>Standalone mode<\/strong><br \/>\nThe integrated alarm evaluation is switched on. Two alarm levels with switch-off hysteresis can be stored in the programming. Alarm level 1 is designed as a pre-alarm and is a non-memory NC contact. Alarm level 2 (main alarm) switches a latching NC contact. After falling below this alarm threshold, the alarm is maintained and must be acknowledged via the reset input. A fault signaling contact signals malfunction and overrange. In addition, the measured value is output as a 4 &#8230; 20 mA signal for further processing.<\/p>\n<p>\u25cf <strong>Transmitter CL<\/strong><br \/>\nIf the alarm evaluation functionality is not required, the sensor can be operated with the integrated CL option. In this case, the sensor supplies the measured gas concentration in the form of a 4 &#8230; 20 mA signal for further processing in an alarm center; the alarm switching contacts are not activated<br \/>\n.<\/p>\n<p>Operating parameters are programmed and the measuring element adjusted via the optionally available, also explosion-proof, control unit.
