The positions for maximum capacity and ignition
capacity can be set using the actuator. Terminal 51
checks whether the position for maximum capacity has
been reached. Terminal 52 checks the position for igni-
tion capacity. If the position is not reached within the
timeout time of 255 s, a safety shut-down of the BCU
will be performed. A fault message (A
, A or A ) will be
displayed, see page 51 (Fault signalling).
If a controller enable is active, the control system is
enabled for operation via the outputs at terminals 53
and 55.
