11 (39 BUTTON DESCRIPTION AP901 contains one single push-button (SET) that can be used for all operational functions of the unit. The push-button is utilized for auto-configuration of the system (see chapter 3.3.1) and for resetting the indicators and latched output relays.
12 (39 IPSWITCH SETTINGS AP901 functionality such as tripping logic is configured using dipswitch settings. Different trip schemes can be easily programmed by selecting the appropriate dipswitch positions. This gives users the flexibility to change settings dependent on application. Tripping may be selected based on arc light only or arc light and current thresholds (or other tripping criteria such as undervoltage, or similar).

Logic scheme 0 The AP901 logic scheme 0 can be not only applied as stand-alone arc protection unit, but also widely used as non-selective outgoing feeder compartment protection. Depend on this scheme, user can select either light only mode or arc light + overcurrent mode to trip all circuit breakers.
Page 15
Logic scheme 1 The AP901 logic scheme I is mainly utilized in selective arc protection solution. The fiber sensor S1 monitors the outgoing feeder cable compartment. The fiber sensor S2 monitors the corresponding feeder breaker compartment and busbar compartment. Trip contact T1 is responsible for tripping circuit breaker of the outgoing feeder.

If one or more of the sensors are disconnected the healthy sensors remain in use and unit remains operational accordingly. The AP901 will remain in error mode until the disconnected sensors are repaired.
ICE representative for a solution to your particular application. APPLICATION WITH CURRENT AND LIGHT CONDITION AP901 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 and the trip relay will be activated in 7ms.

Synchronous Generator (PMSG) is applied with a converter cabinet and LV/MV transformer. The AP901 is equipped with four point sensor channels and each channel may have up to three sensors (type AS01) connected in series allowing for up to 12 point sensors. Additionally one fiber optic loop sensor channel is available as an option.

Breaker failure function is activated if AP901 detects the presence of light after a set operate time. When AP901 is set to operate on light and current both parameters must persist to activate CBFP. Breaker failure can be set to operate either on 100ms or 150ms delay (see chapter 3.5).
25 (39 UTPUTS 7.1.1 T RIP RELAYS The AP901 unit has integrated trip relays T1 and T2 for tripping of the circuit-breakers. T1 and T2 relays are normally open type (NO). 7.1.2 T RIP RELAYS T3 relay output may act either as an electronic lock-out relay or as a trip relay. This option must be specified when ordering.
AS02) may be connected to each channel. AP901 has an option of one fiber optic loop sensor channel with transceiver and receiver (Tx, Rx). When the fiber optic loop sensor is connected to the unit one end is connected to Tx and another to Rx.

10.4 T ESTING ARC FLASH PROTECTION UNIT OPERATION TIME The AP901 operation time test is not required at commissioning as it is performed by the manufacturer as a type test and routine production test. Refer to routine test reports sent with AP901 unit and consult your nearest ICE representative for type test reports.
