ERR31
Alarm on the external display - MMIGRS2
If the communication to the display is not carried out correctly, it
will send an “ERR31” error notification.
This may be caused by the displayed wires H to R not being
installed, or that there have been interruptions in data
communication during the time when the display retrieves the
basic information from the controller.
Once the terminations have been inspected, you should then
check the software version of the external display. This is done by
holding down the Enter key and the X key for 5 seconds, until the
Bios menu appears.
Next, press the X key and read off the software version in the
bottom right corner. The software version must be 1.13 or newer.
Once the display’s software version has been checked, check the
display’s settings as follows:
1. Hold the Enter key and the X key down for 5 seconds, until the
Bios menu appears.
2. Select the “MCX selection” menu
- Select the “Clear UI” line and press Enter
- Select the “Autodetect” line and press Enter
3. Press the X key to return to the Bios menu
4. Select the “COM selection” menu
- Select the “CAN” line and press Enter
5. Press the X key to return to the Bios menu
6. Select the “Start up mode” menu
- Select the “Remote application” line and press Enter
7. Press the X key to return to the Bios menu
8. Select the “CAN” menu
- Select the “Baudrate” line and check that it is 50K
- Select the “Node ID” line and check that it is 126
9. Press the X key to return to the Bios menu
10. Select the “Application” menu and press Enter.
The display will once again retrieve data from the controller.
This process will take about 5 minutes.
