NOTE!
In order to use the digital inputs as "active low", remove the jumper between XC1:11 and 12 and
install it between XC1:12 and 13.

Figure 3.20 - Connector XC1 and DIP-switches for selecting the signal type of the analog inputs and outputs
The analog inputs and outputs are factory set to operate in the range from 0 to 10 V; this setting may be
changed by using DIP-switch S1.

Parameters related to the analog inputs and outputs (AI1, AI2, AO1, and AO2) shall be programmed according
to the DIP-switches settings and desired values.
Follow instructions below for the proper installation of the control wiring:
1. Wire gauge: 0.5 mm² (20 AWG) to 1.5 mm² (14 AWG).
2. Maximum tightening torque: 0.50 N.m (4.50 lbf.in).
3. Use shielded cables for the connections in XC1 and run the cables separated from the remaining circuits
(power, 110 V / 220 Vac control, etc.), as presented in
. If control cables must
cross other cables, it must be done perpendicularly among them, keeping a minimum of 5 cm (1.9 in) distance
at the crossing point.
