CC9 Board
Figure 3.13 - Dip switch position for
(0 to 10) V or (0 to 20) mA/(4 to 20) mA selection
As a default the analogue inputs are selected as (0 to 10) V. This can be
changed using the dip switch S1 on the control board.

Related Parameters: P221, P222, P234 to P240.
During the signal and control wire installation you must follow these
guidelines:
1) Cable Cross Section: 0.5 mm² (20 AWG) to 1.5 mm² (14 AWG );
2) Max. Torque: 0.50 N.m (4.50 lbf.in);
3) XC1 wiring must be connected with shielded cables and installed
separately from other wiring (power, control at 110 V/220 Vac, etc.),
according to table 3.8.

Table 3.8 - Wiring separation distances
If the crossing of these cables is unavoidable, install them perpendicular,
maintaining a minimum separation distance of 5 cm (2 in) at the crossing
point.
