The RBW actuator reports that it has reached the posi-
tion for maximum capacity via a signal to terminal 51.
The actuator reports that it has reached the position
for minimum capacity via a signal to terminal 52. The
simultaneous activation of terminals 51 and 52 results
in a fault lock-out of the BCU.
If parameter 41 = 0, the system monitors the movement
to the positions for maximum and minimum capac-
ity with a timeout time of 255 s. Reaching the relevant
position immediately triggers the program continue
switch conditions. If reaching the position is not sig-
nalled within the timeout time of 255 s, a safety shut-
down of the BCU will be performed. A fault message (A
or A ) will be displayed, see page 51 (Fault signal-
ling).
If parameter 41 = 1, the system does not monitor

whether the positions for minimum and maximum
capacity are reached. In this case, a running time of
up to 250 s must be defined using parameter 42, see
page 84 (Running time). The program continue
switch conditions are then controlled dependent on
this time.
If a fault occurs, the actuator is moved to the position

for minimum capacity.
