What does EALM message mean on Sensitron Gas Detectors display?
The EALM message on the display indicates that the detector's power supply is outside the specified range of 12VDC to 27VDC. To resolve this, check the power supply at the + and – terminals of the detector.
What to do if EI2C message appears on Sensitron SMART 3 display?
The EI2C message indicates a communication failure between the sensor head and the SMART 3 microprocessor base. First, ensure the detector is not installed in an environment with operating temperatures exceeding 60°C, and relocate it if necessary. If the problem persists, replace the sensor head with a new one.
Why EBCH message appears on Sensitron SMART 3 Gas Detectors display?
The EBCH message appears because the dip-switches (1 & 8) for restoring default data are in the wrong position. Refer to the technical manual of the detector for instructions on how to set the dip-switches to the correct position.
What does EAMP message mean on Sensitron SMART 3 display?
The EAMP message indicates that the SMART base does not recognize the serial number of the connected sensor head, potentially because the heads between two detectors have been swapped. Verify that the serial number on the head matches the serial number label on the detector.
How to fix three horizontal lines on Sensitron Gas Detectors display?
Three horizontal lines on the display indicate a zero-value drift. Ensure you are in a clean air environment and perform a zero calibration.
What to do if EE2P message appears on Sensitron SMART 3 Gas Detectors display?
The EE2P message indicates an anomaly in the detector's internal E2Prom memory. Perform a reset operation using the access code 459.
What does EFLS message mean on Sensitron SMART 3 display?
The EFLS message indicates an anomaly in the detector's internal Flash memory. Perform a reset operation using the access code 459.
What to do if ERAM message appears on Sensitron Gas Detectors display?
The ERAM message indicates an anomaly in the detector's internal RAM memory. Perform a reset operation using the access code 459.
