Description
Press and hold the “AUTO” button for 2sec, the LED above the button

4.2 AUTO Control Sequence:
The controller is running in “AUTO” mode.
When Mains (Utility) is normal, Mains is on load:
When Mains is normal, both voltage and frequency of Mains are within the range of preset value, the
Mains Normal LED illuminates, the timer for Mains ON delay is activated, when it times out, the MCB
close/open relay closes, the transfer switch switches on Mains, the Mains Aux. Switch’s contact feeds
back the signal to a configurable input on our controller. The MCB closed LED illuminates.
WARNING:
The Mains Normal LED illuminated means that both voltage and
frequency of Mains are within the range of preset values; Mains Normal
LED flashing means either voltage or frequency of Mains are over the
range of preset values; Mains Normal LED does not illuminate means that
the Mains voltage is lower than the measuring range.
Do not assume the Mains is not available if Mains Normal LED does not
illuminate.
Mains fail to load:
If MCB close/open relay is closed, the timer for MCB closing is activated, when it times out, if the
controller does not receive the feed back signal from the Mains Aux. Switch’s contact, then Mains fail to
load is activated.
