and thus in the interference of analog signals. In this case,

only ground the cable at one end.

X Do not lay signal lines parallel to power cables.

X Connect inductive loads to be switched via the easy

outputs to a separate power feed, or use a suppressor

circuit for motors and valves. If loads such as motors,

solenoid valves or contactors are operated with easy via

the same power feed, switching may give rise to

interference on the analog input signals.

The following circuits contain examples of applications for

analog value processing.

Setpoint potentiometer

Figure 19: Setpoint potentiometer

Use a potentiometer with a resistance of F 1kO, e.g.

1kO,0.25W.

Ensure that the reference potential is connected. Connect

the 0 V of the power supply unit for the different setpoint

potentiometers and sensors shown in the examples to the

0 V terminal of the easy power feed.
