Mci with
bypass contactor
input controlled
soft start
electRical connections and WiRing
By means of the built-in auxiliary
contact (23-24) the bypass function is
easily achieved (see wiring diagram
below).
No heat is generated by the MCI.
As the contactor always switches in
no-load condition it can be selected
on the basis of the thermal current
(AC-1).
(Contacts 13-14 are not applicable with
MCI 25C)
When control voltage is applied to
A1 - A2, the MCI soft starter will start
the motor according to the settings
of the ramp-up time and initial torque adjustments. When the control voltage
is switched OFF, the motor will switch
off instantaneously.
