5.6.2 Additional Configurable digital inputs.
The controller XC645D is provided with 3 additional configurable digital inputs, one of them can
operate also as probe. Their functions are set by the parameter iF05, iF07 and iF08 respectively.
They can be used for liquid level monitoring, activate the energy saving function or silence mode
from a external devices.
The digital input connection is explain in the following table

5.7 HP – LP Pressure switches connection
!!!WARNING: controller is provided with both free voltage digital inputs, and main voltage
inputs.!!!!
The main voltage inputs are designed for HP and LP pressure switches.
The low pressure switch has to be connected to the terminal 44 (line)and 45 (common)
The high pressure switch has to be connected to the terminal 45 (common) and 46 (line)
as shown on the following wiring diagram.
NOTE: the main voltage is related to the voltage supply of
the controllers.
Models at 115V or 230V the inputs operate at 115 or 230V.
Models at 24V the inputs operate at 24V.
5.8 Analog output connection
The controller supply up to 2 analog outputs, terminals, kind of output and functionality are shown
in the following table
