POSITIP 855

Technical Information

Output "POSITIP ready for operation"

In order to work with the signal "POSITIP is ready for operation" you

must supply 24 V= to pins 23, 24 and 25 (0 V to pin 10).

During normal operation, pin 11 of D-sub connection EXT has

24 V.
If an error occurs which impairs the functioning of POSITIP (such

as a hardware or checksum error), POSITIP switches the output at

pin 11 to high impedance.
