The Anti-Heeling System AH2000 & AH2000i can work in conjunction with the stability control system and the valve remote control system for bilge and ballast valve control, the precision heeling sensor, mounted athwart to the ship's direction and supplies the heeling angle signal to the master PLC.
The master CPU is housed in a flush mounting box (600 X 600 X 300mm). The front panel of the anti- heeling system includes hardwired selector switch for mode selection and lamp test for manual operation and a mimic panel.
The ballast pump starts only if it get the signal that both resp. valves (BW170V and BW173V, or BW171V and BW172V) are open. These valves will be controlled by means of master PLC or thru Central Vessel Management System / ICSS.
By pumping from:
Starboard to Portside - Valve BW170V and BW173V is Open. Valve BW171V and BW172V is Close.
Portside to Starboard - Valve BW171V and BW172V is Open. Valve BW170V and BW173V is Close.
Anti-heeling control system is only "Enabled" when the pump starter is in "Operation mode “.
Failure of such will render the system "Not operational"
