3.2.4 Control
Wiring
The control wiring (analog inputs/outputs, digital inputs and relay outputs
is made on the XC1 connector of control board (see location in Figure 3.7,
Section 3.2.3).
There are two configurations for the control board: standard version
(CFW-08 line) and Plus version (CFW-08 Plus line), as shown below:
Figure 3.8 - XC1 control terminal description (standard control board - CFW-08)
Note: NC = Normally Closed Contact, NO = Normally Open Contact
