1.3.4. Trip and drop-off timing
Now we can measure trip time: as the DC voltage is removed
when we start the test, we have only one value.
Press ON and pre-adjust the nominal voltage VN. Select
OFF+TIME: as the relay trips, test goes OFF; pressing the
multi-function knob tripping values can be saved. The TRIP
LED (43) turns on and parameters at trip are displayed until
ON or ON+TIME are selected. Confirm save results pressing
the multi-function knob, and proceed with other test voltage,
until all points to be tested are measured.
Now we can measure the drop-off timing. First thing, select
the NO (or NC) level for the relay reset contact:
Timer start/stop > STOP > EXT > Clean (Voltage) > NC
(NO) ESC
Now, press ON+TIME: as the relay resets, pressing the multi-
function knob drop-off values can be saved. Confirm save
results pressing the multi-function knob, and proceed.
