Map Pickup LED:    50AFD Zone-n Flash - Hand Reset, 50AFD Zone-n – Hand/self Reset

The overcurrent level can be tested without an arc flash by separately energising or inverting the arc detector
binary input continuously for the duration of the test for the zone being tested.

If the current setting is low, gradually increase current until element operates.

If the current level required is greater than the thermal limit of the relay, apply 0.9x setting, check for no operation,
apply 1.1x setting, check operation.

Optical sensors such as 7XG31 can be tested by application of a suitable light source. Relay instrumentation can
be used to indicate binary input pickup or by the 50AFD Zone-n Flash outputs.
The 7XG31 devices will typically require 10000 lx light level for 1.25ms to trigger. A high powered photographic
flash is the most convenient means of initiating positive sensor operation.
Note that mobile phone or small compact camera flashes may not have sufficient power to cause sensor
operation but may be suitable if held directly against the sensor.

Check correct indication, trip output, alarm contacts, waveform record.
