(4)
Handheld test device

Voltage supply
The handheld test device is supplied by a 110 - 125 V AC network.
9.4.5
Operation
The status test begins after the voltage supply has been connected. The various components and parameters of the trip unit are queried. If
the status test has been completed successfully, the "ETU STATUS" LED will light up continuously.
If it has not been completed successfully, the "ETU STATUS" LED will flash. The type of flashing indicates what type of fault is present.
The status test can be repeated any time by pressing the "START" button for at least three seconds.
It is also possible to test a trip unit that is already activated, i.e. one that is supplied by an external voltage source. However, it must be taken
into account that the "ETU STATUS" LED may briefly flash twice when the status test result is displayed, even if there have not been any
faults. As a precaution, the status test should be repeated without external voltage supply.
NOTE
Observe the connecting sequence.
Malfunctions and incorrect test results may result if the sequence is not observed.
