Page 11: Push-Button Description
The initialization sequence is performed by pressing the “SET”-button for 2 seconds, and the AP902 sensor LEDs and BI1/BI2 LEDs start blinking. The unit scans these inputs to see if they are connected and when input is detected the corresponding LEDs are lit up to mark that a connection was found. -

Also the CBFP time can be selected by dipswitch setting according to the requirement of the CBFP function. Dipswitches are located at the back of the unit for easy access. See Figure 3-1 AP902 dipswitches and Table 3-2 AP902 dipswitch setting for details of settings. - Page 13 Refer to chapter 3.5.1 and 6 Refer to chapter 3.5.1 and 6 Scheme select Table 3-2 AP902 dipswitch setting selection The chapter 3.5.1 shows AP902 internal logic and dipswitch selections.

Logic scheme 0 The AP902 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 either select light only mode or arc light + overcurrent mode to trip all circuit breakers. -
Page 15: Non-Volatile Memory
Logic scheme 1 The AP902 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. -

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 AP902 will remain in error mode until the disconnected sensors are repaired. -
Page 18: Application Examples
6.1 MV APPLICATION WITH CURRENT AND LIGHT CONDITION AP902 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. -
Page 19: Circuit Breaker Failure Protection (Cbfp)
Breaker failure function is activated if AP902 detects the presence of light after a set operate time. When AP902 is set to operate on light and current both parameters must persist to activate CBFP. -

Page 27: Testing
10 T ESTING It is recommended that the AP902 unit is tested prior to substation energizing. Testing is carried out by simulating arc light to each sensor and verifying the tripping and LED indication. For arc light simulation a superior camera flash type is used: Canon Speedlite 430EX or equivalent. -
