Quick Answer
CHECK_CO_SHUTDOWN_SENSORS: Check CO shutdown sensors daily, after every fuel tank refill, and before each use to ensure proper operation and safety.
Checking Sensor Integrity
To ensure the reliability of CO shutdown sensors, inspect them daily for dust, moisture, and debris accumulation. Remove any obstructions, and gently clean the sensor area with a soft brush or cloth. For extreme environments or heavy usage, clean the sensors weekly.
Monitoring Sensor Response
Verify the CO shutdown sensor’s response to high carbon monoxide concentrations by placing the sensor near the generator’s exhaust. Introduce a small amount of fuel and ignite the generator to produce a low, steady CO level. Observe the sensor’s response and adjust or replace it if it fails to trigger the shutdown within the specified time frame (usually 1-2 minutes).
Sensor Calibration and Replacement
Calibrate CO shutdown sensors annually or as recommended by the manufacturer. When replacing sensors, ensure the new unit is compatible with the generator and follow the manufacturer’s instructions for installation and programming. Replace sensors that have been exposed to extreme temperatures, moisture, or physical damage, and always follow the recommended replacement schedule (typically every 2-5 years, depending on usage and manufacturer recommendations).
