Function Description

The test programs shown in
device you are using is capable of single-pole tripping.
The output alarms mentioned must be allocated to the relevant command relays that are used for controlling
the circuit breaker coils.
The test is started using the operator panel on the front of the device or using the PC with DIGSI. The proce-

of an open-close test cycle. The set times are those stated in Section
Duration" and "Circuit Breaker Test".
Where the circuit breaker auxiliary contacts indicate the status of the circuit breaker or of its poles to the
device via binary inputs, the test cycle can only be initiated if the circuit breaker is closed.
The information regarding the position of the circuit breakers is not automatically derived from the position
logic according to the above section. For the circuit breaker test function (auto recloser) there are separate
binary inputs for the switching status feedback of the circuit breaker position. These must be taken into
consideration when allocating the binary inputs as mentioned in the previous section.
The alarms of the device show the respective state of the test sequence.
