SPER1C1-AAJ ABB Trip Circuit Supervision Relay new
The operation indicators of the earth-fault relay module are the red operation code of the display and the TRIP indicator that indicates operation.When the SPER1C1-AAJ side protection stage ∆I01> starts,the red operation code 1 is lit on the display.Operation of the stage is indicated by the codenumber 2. Start and operation of the SPER1C1-AAJ side protection stage ∆I02> are indicated by the red operation codes 4 and 5 respectively. The codes indicating start and operation remain lit until reset. Should the circuit-breaker failure protection have operated, the operation indicator A remains lit until the operation indicators are reset.When an operate signal is issued by a HV or LV side protection stage of the earth-fault relay module the TRIP indicator is lit, provided the concerned operate signal is linked to a heavyduty output relay TS1, TS2, TS3 or TS4 via a switch of switchgroup SGR2 or SGR5. Should the red operation code 2 or 5 be indicated on the display the TRIP indicator still being dark, the operate signal is not linked to one of the heavyduty output relays

Selection of the blocking signals for the operation of HV side stage ∆I01>. When the switch is in position 1, and the blocking signal linked to the concerned switch is activated, the operation of the stage is blocked.SGB3/1…8 Selection of the blocking signals for the operation of SPER1C1-AAJ side stage ∆I02>. When the switch is in position 1, and the blocking signal linked to the concerned switch is activated, the operation of the stage is blocked.SGB4/1…3 Switching between main and second setting values.When an external control signal is used, the main setting values are effective when the signal is active. When the signal is not active the second settings are effective.When SGB4/1…3 = 0, an external control signal cannot be used to switch between the settings. Then the push-buttons on the front panel or a command over the serial bus have to be used.When SGB4/1…3 = 1, the actual setting values (main settings or second settings) depend entirely on the status of the control signal.

The pushdown storage contains the five latest values recorded (n)…(n-4). Each new value is stored in the first location (n) in the storage and pushes all the previous items one step forward (n-1). When a sixth item is stored the oldest item (n-4) of the storage will be lost.The most recently stored values (n) are available in the main registers. At a maximum four of the previous values are in the subregisters. The leftmost digit indicates the address of the storage location and the other three digits the numerical value of the parameter stored.
