Description
A
Battery-Mode is pushed
System is operated for 10 sec. in back-up operation
B
System
lights up
A malfunction of NSV has occurred or the NSV 401 output displays a short circuit
lights up with Output Power
The NSV 401 is overloaded
C
Output Power
lights up
The display bar indicates the load at the NSV 401 output
does not light up
No load present at the output
D
Battery low
lights up in mains operation
NSV 401 charges the battery bank, the LED turns off when an adequate charge level has
been reached
lights up in back-up operation Remaining battery charge has dropped below a defined critical level
E
A.V.R. active
(Automatic Vol
-
tage Regulator)
lights up
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
F
Battery-Mode lights up
The NSV 401 runs in back-up operation (AC power supply not present or beyond the tole
-
rance range). If necessary, the required power will be obtained from the battery bank
G
Mains OK
lights up
The NSV 401 runs in mains operation
does not light up
Mains voltage beyond the tolerance range, no mains voltage is present at the input (defec-
tive fuse or power failure)
flashes
Mains voltage is present, but no request from the actuator module
H

lights up green
Battery bank OK
lights up red
Battery bank not connected or too high/low impendance of the battery circuit
flashes red
System in back-up operation
flashes green / red
Battery test

polarity
lights up (signal sounds)
The battery bank has not been connected with correct polarity, change the polarity
J
Battery Test
The button (J) must be pressed and held for 3s to initiate the test.
The battery LED (H) indicates the test mode (quickly changes between
red and green).
Duration of test approximately 15s --> After the manual test start,
internal resistance is measured and the result is indicated by the battery
LED (H):
lights up red = Ri <10 mW or Ri >210 mW
flashes green = 10 mW < Ri < 210 mW
(The number of flashes indicate the RI value)

Functions:
•
The NSV 401 is an emergency power supply for 230 V AC D+H SHEV
systems. In combination with the AM 230, the NSV 401 supplies the
connected SHEV drives with mains voltage. In case of power failure they
are supplied with 230 V AC for 7 minutes (When the retriggering function
is switched on after approx. 30 minutes) by the system's battery bank
(72 hr. standby).
• Any ventilation units connected to the system may not be supplied by the
NSV 401.
•
True sinusoidal voltage at the output of the NSV 401
• Marginal distortion factor
•
The parallel circuit of several NSV 401 is prohibited
•
72 hr. standby without power supply
