WARNING!
Refer to 9 Appendix: General Certification Information before installation and operation.
Failure to follow this warning can result in serious personal injury or death.
The S5000 Series gas monitor is factory calibrated and shipped with the most common default options to minimize set up
effort. Using sensors, the device tests the ambient air and triggers an alarm as soon as the gas exceeds a specific
concentration level.
4.1 Startup
4.1.1 Initial Startup
The first time the S5000 is powered on, the following will appear on the display:
• S5000
• Software Version No.
• Sensor Warm-up
• Wait
The S5000 will remain in Start-up mode in which the fault relay is de-energized and the analog output is 3.5mA by default. The
time the S5000 stays in Start-up mode depends on the sensor. See 4.1.2 Sensor Warm Up Times for details on the startup
times of each S5000 sensor. If a dual sensor configuration is deployed, each sensor is able to exit warm up independently.
A full calibration is recommended after onehour of a sensor being installed, powered up, and acclimated to the environmental
conditions. See 5 Calibration for calibration details.
4.1.2 Sensor Warm Up Times
WARNING!
For optimal sensor performance, allow sensors 24 hours (72 hours for ETO) to acclimate to application conditions before
performing an initial calibration
Failure to follow this warning can result in serious personal injury or death.

Carbon monoxide and ethylene oxide sensors, gas codes D10, D11, D12, D14, and D71 may require initial warm-up periods
longer than 30 minutes. If the 30-minute warm up is over, the sensor may show a positive reading that exceeds alarm levels. In
the event of a short-term power outage, the warm-up time will be significantly less. See the table below to estimate required
warm-up time.
