ESTING ARC FLASH PROTECTION UNIT OPERATION TIME
The AP902 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 AP902 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 Canon
Speedlite 430EX or equivalent input for initializing the flash and configure a
relay test set timer to be started simultaneously with flash.
3)
connect AP902 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 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.
