Page 5: General Description
VDC (DC Voltage) SEC 3000 The SEC 3000 toxic gas detector is a microprocessor based intelligent gas detector that continuously monitors toxic gases and vapors ideally suited for use in harsh environments. The SEC 3000 is a stand-alone device providing a continuous 4 to 20 mA output. -
Page 6: Operation Installation And Startup
The first step in the installation process is to establish a mounting location for the SEC 3000. Select a location that is typical of the atmosphere to be monitored or close to the anticipated source of a dangerous gas. - Page 7 The detector continuously checks for system faults or initiation of calibration and automatically changes to the appropriate mode. The 4 to 20 mA output of the SEC 3000 is a non-isolated current source. Current Output and Corresponding Status Current Output Status.

Page 8: Calibration
The electronics will automatically adjust the sensor’s signal to the new zero reference level. During the zero calibration routine, the current output of the SEC 3000 will briefly go to 2.2 mA. Although this can be accomplished manually, installation of a switch (contact closure) can accomplish the zeroing procedure. -
Page 9: Maintenance
V. MAINTENANCE The SEC 3000 does not normally require routine maintenance other than calibration. The only consumable item on the SEC 3000 is the sensing element. The toxic gas sensing element will typically last for 2 years of operation. -
