ESTING THE
CBFP
FUNCTION
Circuit breaker failure function is tested by leaving light signal and second trip criteria signal
(e.g. overcurrent) if applicable active for above set CBFP time of either 100 or 150ms. Trip
relay T2 and binary output BO1 shall be active after set time delay.

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.
However, if it is deemed necessary a site timing test may be conducted using below
instructions.
1) Use a calibrated relay test set
2) Connect an output from the relay test set to camera flash type Metz 20B1 or
equivalent input for initializing the flash and configure a relay test set timer to be
started simultaneously with flash.
3) connect AP901 trip output T1,T2, T3 or T4 to relay test set input and configure the
input to stop the timer
4) Place camera flash to maximum 20cm (12 inch) distance of the AS01 or arc light
fiber optic loop sensors.
5) Initiate flash and timer using relay test set output.
6) Read the measured time between simulated arc and trip contact operation.
7) Subtract the digital input delay of the relay test set from the final measured time if
applicable. For specific test instructions consult the manufacturer of the relay test
set.
