The device is provided
with a built-in phase-moni-
toring function for the
mains supply. In the event
of a mains interruption
(failure of a fuse or mains
phase) the unit switches
o
ff
after a delay (approx.
60 ms).
If the voltage supply returns
within 5 s, the device automati-
cally switches itself back on.
In the case3of mains interrup-
tions over 10 sec. the error
message
“
Line fault
”
appears. A
startup attempt takes place ap-
proximately every 60 sec. until
all three mains phases are
available.
