Functions
Limit value monitoring
If the shut-off valve is in the blocking state, the amount of the measured pressure change is compared
with the upper pressure change limit value, Pm.15-16, parameter using a comparator. If limit value
monitoring is activated, Pm.0.6, the appropriate error/diagnostic message is output if the limit value is
exceeded.
Monitoring of parameters
The unit pressure, Pm.8.0-8.1, pressure change sample time, Pm.10, and upper pressure change
limit value, Pm.15-16, are checked for permissible values on input. In the event of an error, the
corresponding error message is output if parameterisation error monitoring is activated, Pm.0.7.

User-controlled blocking
If the auto blocking control bit output, Am.0.1, is inactive, the shut-off valve can be controlled
directly with the blocking control bit output, Am.0.0. The pressurise control bit output, Am.0.2, has no
influence on the switching status of the shut-off valve.
