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. 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 arc light fiber optic loop
sensors if in use.
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) signal is utilized verify the BO1 signal activation by
status change of relevant input where binary output signal is connected or by
measuring the signal output voltage. Note that BO1 signal is a non-latched
type.
7) If binary output signal is utilized verify that BO1 LED is lit.
8) Press SET push-button to reset all indications and latches.
9) If binary input BI2 is utilized for master trip activate the corresponding binary
input and verify that trip has occurred by repeating 4 and 5.
10) Press SET push-button to reset all indications and latches.
11) Repeat the testing procedure for all sensors.
