6.1.2. Mimic Panel
Mimic panel is a diagram, which shows the path of energy flow in the UPS by means of several
LED’s. Definitions of LED states are shown below:
Input mains voltage is OK and rectifier is active
Input mains voltage is OK and rectifier is inactive
Input mains voltage is very close to its upper/lower limit and
rectifier is active
Input mains voltage is not OK
Bypass mains voltage is not OK and output voltage is not
synchronized to the bypass voltage
Bypass mains voltage is not OK
Battery mode is active and battery voltage is OK
UPS is performing battery test and battery voltage is OK
Battery mode is active and battery voltage is close to its lower limit
(energy available in the battery is about to be depleted)
Battery test is active and battery voltage is close to its lower limit
(energy available in the battery is about to be depleted)
Rectifier is active and able to supply whole power required by the
inverter
Load is powered but UPS is overloaded
Load is fed via static bypass line
