6.4.4.2 The System Indication of ‘PMS Limitation’ Signals
The PMS limitation signal is delivered from external equipment which can control the thruster, and has higher priority
compared to NAVIS NavDP 4000 . This equipment may be for instance the vessel’s power management system. If this
signal has come, the thruster command signal is limited by the external equipment, so that it may be the feedback signal
differs much from the command signal set by
NAVIS NavDP 4000 . This situation is not interpreted as a failure.
The following elements indicates when the signal is obtained:
– bus becomes red-colored on the power mimic diagram and the inscription ‘PMS Limitation’ is indicated above the
bus (Figure 6.45)
– the power limited thruster indicator becomes yellow (Figure 6.46)
– power limited thruster symbols become yellow on the Power mimic diagram (Figure 6.47)
When the signal is lost this indicator disappears and the bus becomes blue-colored.
