Notes:
1. the inputs on the Base Control Module are only used by
this Operation Mode if Fieldwire is selected for one of
the control sources. If Fieldwire is not the Local or
Remote control source, all 4 inputs may be used as
general purpose inputs or can be selected as the
feedback source for the solenoid limit switches.
2. Outputs 2 and 3 may be used as a general purpose
outputs for this Operation Mode.
3. If Fieldwire is the Local control source, Input 3 is the
Remote input. When power is applied to Input 3, the
C445 will be in Remote mode.
4. If fieldwire is the Remote control source and 2-wire
control (default) is selected, Inputs 2 and 3 are unused
by this operation mode. They can be used as general
purpose or selected as the feedback source for the
solenoid limit switches.

5. If 3-wire control is selected along with Fieldwire for
either control source, Input 2 is Permissive.
6. Fusing: Although C445 product listings do not require
fusing on the high impedance line voltage measurement
inputs, it may be necessary to provide overcurrent
protection of the supply leads in accordance with
applicable final installation specific local, state and
national electrical codes.
7 . C445UC... control user interfaces offer 4 additional
24 Vdc digital inputs for general purpose use. Inputs 2
and 3 can be selected as the feedback source for the
solenoid limit switches.
