The 2 x 20 character LCD simplifies the communication with the UPS and provides the necessary monitoring
information about the UPS. The menu driven LCD enables the access to the:
• Even register (event log)
• Show measurements such as U, I, f, P, Q, S, load %, battery runtime and others
• Perform commands like start-up and shut-down of UPS and others
• Load transfer from INVERTER to BYPASS and vice-versa
• Diagnosis (SERVICE MODE)
• Adjustments and testing
6.5.1 LED Indicators
The mimic diagram serves to indicate the general status of the UPS. The LED-indicators show the power flow
status and in the event of mains failure or load transfer from inverter to bypass and vice-versa. The corresponding
LED-indicators will change colors from green (normal) to red (warning).
The LEDs LINE 1 (rectifier) and LINE 2 (bypass) indicate the availability of the mains power supply.
The LEDs INVERTER and BYPASS if green indicate which of the two is supplying power to the critical load. When
the battery is supplying the load due to mains failure the LED-indicator BATTERY is flashing.
The LED-indicator ALARM is a visual indication of any internal or external alarm condition. At the same time an
audible alarm will be activated.
