    LED will remain as blinking status. This means that SF relay will energize and the error led will turn off. If one or more of the sensors are disconnected the healthy sensors remain in use and unit remains operational accordingly. The AP901S will remain in error mode until the disconnected sensors are repaired.

  • Page 27: Application Examples

    OUBLE USBAR APPLICATION WITH CURRENT AND LIGHT CONDITION AP901S may be applied requiring both overcurrent and arc light conditions for trip. In this case tripping is performed only if both conditions are fulfilled simultaneously. Typically the overcurrent condition is obtained from the AP910 unit or monitored by NP900 Series protection relays also (e.g.

    T1, T2 RIP RELAYS The AP901S unit has integrated trip relays T1 and T2 for tripping of the circuit-breakers. T1 and T2 relays are normally open type (NO). Trip relay T4 is a common trip relay that operates anytime T1 or T2 relay operates and can be used either for tripping one more disconnecting device or for trip alarm to local or remote monitoring and alarming system.
