206 Troubleshooting guide
Manual Energy Storage Inverter ESI-S
In general the occurrence of transient faults is no problem for the proper operation of
the energy storage inverter. Only when an error becomes ‘critical’, a problem may exist.
If ‘ACK. FAULT’ is present on the ESI-Manager display, look at the ‘Armed’ indicator (By
default mapped to the 4
th
digital output of the ESI-Manager) to know whether the
inverter will restart automatically after clearance of the problem or not.
‘Armed’ indicator ON: The inverter waits for the problem to disappear and then restarts
automatically (unless the user acknowledges the fault).
‘Armed’ indicator OFF: The inverter is permanently stopped and the customer has to
solve the problem, acknowledge the fault and restart the inverter manually.

11.4 Troubleshooting guide
11.4.1 Verification of the ESI-Manager status and the system LEDs
As a first phase of troubleshooting make a record of the information provided by the
ESI-Manager:
−
‘ACK. FAULT’ message present of not
−
Inverter event log information messages
−
Alarm horn on or not?
−
Status of the digital output contact monitor
The most recent messages are shown first in the event log.
