ESTING
It is recommended that the AP901S 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 uses a superior camera flash type: Canon Speedlite 430EX or
equivalent. For testing of non-latched signals and CBFP function use Mini Maglite 2 CELL AAA
or equivalent type of flashlight. Check that camera flash or flashlight has fully charged battery
when testing.

ARRYING OUT TESTING IN LIGHT ONLY MODE
1)
Check that the dipswitch setting positions are in accordance to your application
2)
Activate the camera flash within 20cm (12 inches) of the AS01 sensor.
3)
Verify that the corresponding sensor channel indication LED status is changed to
ON.
4)
Verify the relay output(s) activation(s) by checking the circuit breaker status or by
monitoring trip contact status. The circuit breaker should open or contacts operate.
Note: A best practice is to operate the circuit breaker at testing.
5)
Verify that the corresponding relay output(s) LED(s) indication status is changed
to ON
6)
If binary output (BO1, BO2 and BO3) signals are utilized verify the BO signal
activation by status change of relevant input where binary output signal is
connected or by measuring the signal output voltage. Note that BO signal is a non-
latched type.
7)
If binary output signals are utilized verify that binary output LEDs are lit.
8)
Press SET push-button to reset all indications and latches.
