Parameters of the sensor supply

4.2.2.1

Supplied channels

With this parameter, you specify whether and which internal sensor supply supplies which
channel groups. The choice taken applies to the entire channel group (CH0-3, 4-7, 8-11,
12-15).
The following options are available, for example:
Parameter assignment:
Left-hand module side
Sensor supply 0 Sensor supply 1
supplies chan- supplies chan-
nels ... nels
...
0 to 3 4 to 7
0 to 7 -
0 to 3 4 to 7
0 to 7 -
0 to 15 -
You can also supply the sensors by means of an external sensor supply (parameter "None").
The selection of an internal sensor supply is required for using the short-circuit test.

4.2.2.2

Short-circuit test activated

Here you enable the short-circuit detection for the channels of the F-module for which one of
the internal sensor supplies is set ("Supplied channels").
The short-circuit test is always possible when you are using simple switches that do not have
their own power supply. For switches with their own power supply, for example, 3/4-wire
proximity switches or optical sensors with OSSD (Output Signal Switching Device) outputs,
you must adapt the "Startup time of sensors after short-circuit test" parameter to match the
sensor in use.
