Mimic Indications
Six LEDs are mounted on a single line diagram to represent the various UPS power paths. These LEDs, which are annotated in figure7, show the current UPS operational status and should be interpreted as detailed below.
LSI - Input supply OK / Rectifier operative: This led illuminates when the input isolator (I1) is closed, the input supply is within 20% of nominal voltage, and the rectifier is operative.
LS2 - Battery volts OK:
This led illuminates when the battery circuit breaker is closed and the battery voltage is within the UPS operating range - 320V- 432V nominal. (330V - 445V* nominal for the 80 to 125 kVA Models).
LS3 - Bypass supply OK:
This led illuminates when the static bypass supply in within 10% of its nominal voltage and the static bypass isolator is closed.
LS4 - Inverter-output OK:
This led illuminates when the inverter is operating and its output is within a preset acceptable voltage window.
* - In case of battery on boost, this voltage can go upto 475V.
