Off-service diagnostic methods
17.2.8 Minimum Pickup test
The Minimum Pickup test determines the minimum voltage required to trip or close the circuit breaker.
By using the internal power source of CIBANO 500, the coil supply voltage is increased step by step
through an automated test sequence until the circuit breaker operates.
Note: To perform the Minimum Pickup test, you need a license. Without the license, it is not possible to
start the measurement and Primary Test Manager displays a missing license message. To get the
license, contact your regional OMICRON service center.
Connection
To connect the test object to CIBANO 500:
1. In Primary Test Manager, open the Minimum Pickup test.
2. In the Hardware configuration area, set the hardware configuration.
Often you can leave the cables as already connected in the previous test. Unused sockets can
remain connected.

WARNING
Death or severe injury caused by high voltage or current possible
► Do not connect anything to the circuit breaker under test without grounding the circuit breaker.
► Always ground the circuit breaker on both ends on all phases and close the circuit breaker to
have proper grounding between the interrupters.
