Battery Voltage Monitoring
Parameter 221
Batt.undervolt.
U < 00.0V
Battery voltage monitoring: Threshold value 9.5 to 30.0 V
If the measured value falls below this threshold value for at least the delay time
(Parameter 222), the following alarm class is issued.
Issuing of class F1 alarm
Parameter 222
Batt.undervolt.
delay 00s
Battery undervoltage delay 0 to 99 s
For the control unit to recognize a battery undervoltage fault condition, the thre-
shold value configured in Parameter 221 must be exceeded without interruption for
t
his period of time.
Note: Regardless of the configured battery voltage monitoring threshold, readiness
for operation is withdrawn and an alarm message is issued if the power supply vol-
tage falls below 9 Vdc or if the power supply voltage falls below 11 Vdc during the
start sequence.
Time Of Active Horn
Parameter 223
Horn self reset
0000s
Horn acknowledgment after 1 to 9.999 s
The horn (centralized alarm) will remain active for the time configured and then
