The module is tested completely during operation.
The main test routines are:
• Switch-on and switch-off capability
• Crosstalk on the input circuits by walking-zero
• Functions of the input filters
• Correct function of the module
• Short circuit and wire break of the sensor line
The LEDs are not tested.
Figure 2: Connection wiring
* The connections (X4) to (X32) are only used at special cable connectors.
Termination of not used inputs
Figure 3: Resistor circuit for the inputs
Note Not used inputs, which are connected in the HIMA function block HB-
RTE-3, must be terminated with a 10 k
Ω resistor at the input of the
module. Thereby line error messages of the not used input channels
are eliminated (see following scheme).
