Ideal for: offshore platforms, offshore wind farms, bridges

The NOMAN 300 (Normal Operations Monitor Aids to Navigation) is designed to monitor an aids to navigation (AtoN) system and provide a contact closure for an out-of-tolerance condition.

Features:

• Customizable monitoring system for multi light platforms
• Battery monitor for checking the light system and sound signal system batteries
• Additional sensing circuits to check the DC current of the sound signal system for normal current drain
• Form “A” contacts for common alarm standards; other alarm contacts optional
• The navigation light monitoring sections of the NOMAN consists of a PLC that monitors the status contact of either LED flashers or incandescent lampchangers
• The light monitor circuit is a microprocessor-based system which checks each lantern’s status contact for low voltage or low impedance when the lantern timer is on or for high voltage when the timer is in eclipse
• DC current for sound signal is routed through the monitor circuit and checked for proper current level by a hall effect sensor
