Description
Input Over
Voltage Warning
During operation, the Charge Controller continuously monitors
the input voltage. If the voltage exceeds 137 Vdc (± 1 V) for one
second, the Charge Controller displays an Input Over Voltage
Warning. The warning clears itself when the voltage falls to
134 Vdc for 1 second.
Input Over
Voltage Fault
During operation, the Charge Controller continuously monitors
the input voltage. If the voltage exceeds 142 Vdc (± 1 V), the
XW SCC instantly registers an Input Over Voltage Fault. The
detection circuitry is faster than breakers or fuses, and they will
not trip or blow when a fault occurs. The fault clears itself when
the voltage falls to 140 Vdc for 5 seconds.
Battery Over
Voltage Fault
Battery Over Voltage Fault appears when the battery voltage
becomes abnormally high and the XW SCC stops charging to
protect the batteries. The fault occurs when battery voltage rises
above the nominal voltage plus:
•
4.5 V per 12 V (for example, above 33 V in a 24 V system)
for 1 second.
•
5.5 V per 12 V for 20 milliseconds.
The fault clears when battery voltage falls to the nominal
voltage plus 3.5 V per 12 V for 10 seconds.
