2.13 Identifying a faulty module (Variant 2)
Important:
-
The number of modules must always be adapted in the Web Interface (Installation Config) as soon as
modules are added or removed from the system.
-
Please perform a visual check of the communication pins according to step 2.11 for each module.
1. Build the Battery-Box with only 3 Modules (+ Base and BCU). Adjust module amount in the Web Interface under
Installation Config. Note: The module amount must be adjusted whenever the number of modules is changed.
2. Check status:
Note:
The battery status is OK when battery is on (Air Switch up and WIFI available) & no errors are shown (Web
Interface: Current Alarm). Otherwise, the battery status is NOT OK.
OK:
Add one module at a time, adjust module number in web interface and check again. If battery status turns to
“NOT OK”, then the defect module is identified to be the one that has been added newly.
NOT OK:
The defect module is probably one of the 3 modules in the tower. Take one of the spare modules and exchange
each of the 3 modules with the spare module one at a time. Check the battery status after each step. If battery
status turns to “OK”, the defect module is the one that was exchanged.
3. If the defective module is found, it may be replaced by a new replacement module. Please contact
EFT-Systems.
