UPS: MKD 700 – 3000 VA RT (XL) UPS Device Description
By-pass mode (BY-PASS MODE): The device is in
by-pass mode, i.e. the UPS output (the load) is fed
directly by the power supply. During this operation
mode, the UPS scarcely carries out a protective or
support function. An acoustic signal is given during
this operation mode (Beep every 2 minutes).
Power-saving mode (ECO MODE): The device is
permanently in static by-pass mode. The protective
functions are limited but the UPS support functions
remain intact. If the power supply is instable, the
UPS switches to the inverter mode. The switchover
time is to be considered here. The ECO-MODE can
be set via the parameter settings or the software
application.
Converter mode (CONVERTER MODE): The
converter mode can be set via the parameter
settings or the software application. An adaption of
voltage and frequency for specific loads which
deviate from the power supply can occur here. The
inverter is always in operation during this operation
mode. Mind that the UPS output is loaded to a
maximum of 80%.
Test mode (TESTING MODE): When the test mode
is initiated, the UPS switches to the inverter mode
for approximately 10 seconds and performs a
battery bank test.
Warning mode (WARNING MODE): In the event of
an irregular state occurring in the UPS, e.g. the
temperature is too high, the UPS issues a warning.
This must be taken seriously, and corrective actions
should be taken even if the UPS still possess full
functional capability for a significant time.
An acoustic signal is given during this operation
mode (beep every second).
