When this error message appears, replace the sensor board.
Sensor # Sensor Missing
If no gas sensor is present on the sensor board, this error message will appear on the display.
Verify that there is a sensor on the sensor board and that it is fully seated in its socket. If not,
place the sensor firmly into the socket. If the issue persists, the sensor detection switch may
need to be replaced.
Sensor # Calibration Invalid
When a sensor board does not have zero and span values saved in memory, this error will be
shown. This is often due to damaged or corrupted memory.
Replace the sensor board to correct the error.
Relay Board # Communication Loss
This error message means that the panel is unable to communicate with the indicated relay
board and attempts to reestablish communication have failed. Once the panel is able to
communicate with the relay board again, the error message will clear. As the relay board is
without a control signal during this error state, all relays on the board will default to their normal
position.
The most common reason for this error message is improper wiring. Another reason is that the
relay board is addressed incorrectly, either matching the designation of another relay board or
being set to an inactive address.
SD Card Error – Insert SD Card
If there is no microSD card present in the control panel, this message will appear. The panel
will not be able to record data without a microSD card.
Inserting a microSD card will clear the message. If the error message does not clear, try a
different microSD card. If the error message still does not clear, replace the SBC on the back
of the display.
SD Card Error – Replace SD Card
The control panel will display this error message if it is not able to write data to the microSD
card. This could be the result of a corrupted block of memory on the card or too many write
operations being performed over the lifespan of the card.
Replace the microSD card to clear the error.
