2.Model Dependent Operations of Louvers driven by DC Stepping
Motor
NFC model:
These are the only models with two independent louvers:
x
the horizontal louver which is driven by an AC motor, and
x
the vertical louver which is driven by a DC stepping motor
Since the RC2 or RC3 can support only one louver, the user must use a RC4 or RC1
to control the operation of the two louvers of a NFC. If RC2/RC3 is used, only the
vertical louver is controllable, the AC motor is always stopped.
