What to do if De Nora Capital Controls CHLORALERT 17CA3000 Gas Detectors show calibration-related events?
If your De Nora Gas Detectors are showing calibration-related events like 'Fail Zero Cal' or 'Fail Span Cal', you can: 1. Check the sensor housing for dust or contaminants that might be blocking the gas flow. 2. Replace the sensor.
How to fix moisture in De Nora Gas Detectors sensor housing?
To address moisture inside the sensor housing of your De Nora Gas Detectors, ensure the sensor housing cover is correctly oriented.
What to do if keypad inactive on De Nora Capital Controls CHLORALERT 17CA3000 Gas Detectors?
If the keypad on your De Nora Gas Detectors is inactive, remove the receiver and make sure the keypad ribbon cable is securely attached to the PCB header.
Why is there no power or LCD display on De Nora Capital Controls CHLORALERT 17CA3000 Gas Detectors?
If your De Nora Gas Detectors have no power or the LCD display is not working, check for AC power at the receiver. If there's no power, check for AC power at TB1. If power is present at TB1, inspect the power fuses.
What to do if De Nora Capital Controls CHLORALERT 17CA3000 show sensor-related events?
If your De Nora Gas Detectors display sensor-related events such as 'Bad sensor id', 'Bad sensor', 'Bad k-value', 'Fail sensor check', 'Bad gen schk', 'Bad id schk', or 'Over range', here’s what you can do: 1. Inspect the sensor housing for any dust or contaminants that might be obstructing gas flow. 2. Verify all interconnection wiring for loose or missing connections. 3. Measure the voltage between terminals 3 and 4. It should be between 12 and 15 VDC. If there's no voltage at the sensor, inspect the corresponding terminals at the Receiver Sensor Interface terminal block TB3. 4. Check the voltage polarity at the Sensor. Terminal 4 should be positive relative to terminal 3. 5. Within 40 seconds after initiating the Sensor Check, measure the voltage across the gas generator. If it ex...
