Drive lever control unit
51
Read this manual carefully before starting any work!
This is particularly applicable to the chapter “General Safety Instructions”
and the respective safety instructions in the chapters.
Start ready = NC
Requirements for the signal „Start ready“:
At this input pin (B2) a TRUE signal (high level) can only be applied by the drive lever control if the drive
lever control unit:
S does not request a gearbox direction
(drive lever control unit requests neither gearbox forwards or gearbox reverse)
AND
S there is no drive lever request
(output towards MAN Marine electronics: drive lever position = 0 %, corresponds to power signal = 4 mA)
AND
S it is ensured that an active command transfer to an operator's stand that is assigned to the drive lever
control unit has occurred
The signal is used:
- in the classified system for local-remote switching
- in the non-classified system for start blocking
→ Hence this input pin must not be permanently set to TRUE signal (high level)!
Requirements for the signal „Throttle fail“:
The input pin X9/B5 “Throttle fail” serves for monitoring the functionality of the external drive lever control unit.
For local-remote switching for classified systems, on the part of the external drive lever control it must be
ensured that the input pin X9/B5 “Throttle fail” is set to FALSE signal (low level) if an implausible state is
present between gearbox control and feedback.
→ set to Low Signal, due to open circuit monitoring!
High level = everything OK
Low level/open = alarm
