F3237 HIMA 984323702-8 Fold Input Module

Description:

The module is automatically tested completely during operation. The main
test routines are:
- Switch on and switch off cability
- Crosstalk of the input circuits by walking 0 test
- Function of the input filters
- Correct function of the module
- Short circuit and wire break of the sensor line
Function of LEDs are not tested.
Appertaining softw. building block: HB-RTE-. (for current version refer to
the description of the operating system).

Proximity switches outside the DIN 19234 standard

Different proximity switches are not according to the DIN 19234 standard.
E. g. the proximity switch type NJ 5 - 30GK - S1N of the P&F company delivers a very low current in the non-damped state. This effects the reaction
of the line break supervision of the F 3237 module
Nevertheless to guarantee a correct function also in this case it is possible
to increase the output current of the proximity switch to 170 µA in the nondamped state by switching in parallel a resistor of 47 kΩ.
There are no limitations concerning the using in fail safe circuits because
a break of the resistor would be signalled like a line break. Also a real line
break will be detected as before.
