5.1.5.3 Switch to the pressurise state
If the auto blocking timer has expired, status = UP, the blocked shut-off valve can only be switched to
the pressurise state under user control. There are the following options for switching:
–
Edge-controlled: positive signal edge at the pressurise control bit output, Am.0.2. Detection of
a rising edge resets the timer to the RESET status once only. Automatically-controlled blocking
remains active.
–
Level-controlled: deactivation of the auto blocking control bit output,Am.0.1. The timer remains in
the RESET status for as long as this output is deactivated. If the auto blocking control bit output is
reactivated, automatically-controlled blocking is active again.
When the timer is reset and the locking control bit output, Am.0.0, is deactivated, the shut-off valve
switches to the pressurise state.
