The control panel does not communi-
cate with one or more connected
units.
This error may occur:
• when a connected unit is removed
or replaced,
• due to a brief error in the power
supply of a connected unit,
• due to incorrect cabling,
• due to a fault.
1. Check whether all connected units are provided with
mains supply.
2. Check whether the dummy plug on terminal X535 of the
last connected unit is present.
3. Check the control cables:
• are they correctly connected and free of breaks?
• are they stretched out or rolled up in a bifilar coil?
• are they shielded from magnetic fields?
4. Check the fuses.
5. Check the wiring between the control panel and connec-
tions X530 and X535 and X60 in the unit.
6. Reset the system if the error message does not automat-
ically disappear.
E2
There are units connected that have an
invalid or unknown unit code, or an
invalid combination of unit types.
Check and compare the unit types on the type plate. The
units must have the same battery type and preferably the
same capacity.
The control panel software is outdated. Check the version number of the software via
menu > Maintenance > Status
.
The control panel does have power but
is not communicating with any unit.
1. Check the control cables:
• are they properly connected and fully intact?
• are they stretched out or rolled up in a bifilar coil?
• are they shielded from magnetic fields?
