General
²
Make sure that the HEALTHY LED (Green) on the front fascia lights up. This is how the device indicates
that it is properly functioning and that no failures have been observed during self-monitoring.
²
Make sure that the LEDs on the front fascia present a plausible image of the actual state of the device.
For example, after the tripping of a protection function, the device has fault indications (if configured)
and a fault record for this purpose.
²
Press the LED test key. All LEDs must light up. Stored LED displays are reset and only those states
currently indicated by the device are shown.
²
Read the operational measured values and compare them to the actual measurands to control the analog
inputs. To do this, enter a reference quantity into the device using secondary test equipment. This is how
you check the proper operation of the analog section of devices.
²
Read the operational indications. You can do this directly on the device or following a clearly arranged
procedure using Reydisp Evolution. Make sure that they do not contain inputs about failures of the
device, of measurands or other implausible information. If the protection equipment has picked up or
disabled an error, you can verify this through the fault record and the fault log. This is how the protection
equipment demonstrates its correct operation in the operating state. Additional protection-function tests
can be omitted.
