Battery
The button
must be pressed and held for 3s to initiate the test.
Test
The battery LED
indicates the test mode (quickly changes between red and green)
OK
duration of test approximately 15s --> After the manual test start, internal
resistance is measured and the result is indicated by the battery LED
OK

NSV 401
System is operated for 10 sec. in back-up operation
A malfunction of NSV has occurred or the NSV 401 output displays a short circuit
The NSV 401 is overloaded
The display bar indicates the load at the NSV 401 output
No load present at the output
NSV 401 charges the battery bank, the LED turns off when an adequate charge level has been
Undervoltage or overvoltage is detected on the supply network. The NSV 401 reduces /
increases the output voltage by approximately 13% in order to protect the devices
The NSV 401 runs in back-up operation (AC power supply not present or beyond the
tolerance range). If necessary, the required power (max. 3,200V AC & 2000W) can be
obtained from the battery bank
The NSV 401 runs in mains operation
Mains voltage beyond the tolerance range, no mains voltage is present at the input
(defective fuse or power failure)
Mains voltage is present, but the NSV 401 is deactivated
Battery bank OK
Battery bank not connected or too high/low impendance of the battery circuit
System in back-up operation
Battery test
The battery bank has not been connected with correct polarity, change the polarity
OK
Ri <10 mW or Ri > 210 mW
10 mW < Ri < 210 mW
(Ri the number of flashes indicates the value)
