Activating the Input Channels
All input channels on the analog module are deactivated by default. This state is indicated by
the four yellow LEDs IN1 to IN4 illuminating in sequence. Wire break detection is activated
(parameter bit P3=1). The measuring range is between 4 mA and 20 mA.
Activating an Input Channel
An input channel is activated if an input signal within a range of 1 mA to 23 mA is present. Any
input channels activated remain active after the module is restarted.
Resetting Activated Input Channels
In order to restore the module to its default status, set parameter bit P3 to P3=0 and then to
P3=1. Alternatively, when switching on the module, a signal of < 1 mA must be present at all
input channels for a period of 7 seconds.
