The valve remains open for the programmed time (0 to
60s) after the start-up signal (ϑ) has been deactivated

11.8.4 Running time selection
Parameter A041
Parameter A041 = 0: Off; checking the positions for
minimum/maximum capacity. A signal that the posi-
tions for minimum and maximum capacity have been
reached is returned and monitored with a timeout time
of max. 250s. When the position has been reached, the
BCU will initiate the next program step.
Parameter A041 = 1: On; for approaching the positions
for minimum/maximum capacity. The running time
set using parameterA042 is activated for approaching
these positions, see page91 (Running time). After
this time has elapsed, the BCU will initiate the next pro-
gram step.
Parameter A041 = 2: On; for approaching the position
for maximum capacity. The running time set using pa-
rameterA042 is activated for approaching the position
for maximum capacity, see page91 (Running time).
After this time has elapsed, the BCU will initiate the next
program step. Approaching the position for minimum
capacity is signalled and monitored.
Parameter A041 = 3: On; for approaching the position
for minimum capacity. No signal is returned that the
position for minimum capacity has been reached. The
running time set using parameterA042 is activated for
approaching the position for minimum capacity, see
page91 (Running time). After this time has elapsed,
the BCU will initiate the next program step. Approach-
ing the position for maximum capacity is signalled and
monitored.
