A low signal on terminal "6"
• The energy available is outside of the permissible range of tolerance to be ready
for use.
This can be caused by the following:
• The Energy storage solution is in charging mode and is not yet ready to use.
• Power failure.
• The Energy storage solution is faulty.
The following illustration shows this in detail (

Check whether the power has failed.
If the power has not failed:
Wait for about 10 seconds, until the energy storage has been charged (if extension
modules are connected, the waiting period increases accordingly).
After about 10 seconds, the signal will change from low to high.
