Additionally, all the digital inputs that are connected by default are also enabled
with the setting. Default triggering settings are selected depending on the
connected input signal type. Typically all protection START signals are selected to
trigger the disturbance recorded by default.

3.6.3 Functional diagrams
The functional diagrams describe the default input, output, alarm LED and functionto-function connections. The default connections can be viewed and changed with
PCM600 according to the application requirements, if necessary.
The analog channels have fixed connections towards the different function blocks
inside the IED’s standard configuration. Exceptions from this rule are the 12
analog channels available for the disturbance recorder function. These channels are
freely selectable and a part of the disturbance recorder’s parameter settings.
The analog channels are assigned to different functions. The common signal
marked with 3I represents the three phase currents. The signal marked with Io
represents the measured residual current via a summation connection of the phase
current transformers.
3.6.3.1 Functional diagrams for protection
The functional diagrams describe the IED’s protection functionality in detail and
picture the factory set default connections.

Figure 30: Overcurrent protection
Four overcurrent stages are offered for overcurrent and short-circuit protection.
The instantaneous stage (PHIPTOC1) can be blocked by energizing the binary
input 1 (X120:1-2). Two negative sequence overcurrent stages (NSPTOC1 and
NSPTOC2) are offered for phase unbalance protection. The inrush detection
block’s (INRPHAR1) output BLK2H enables either blocking the function or
multiplying the active settings for any of the described protection function blocks.
All operate signals are connected to the Master Trip and to the alarm LEDs. LED 1
is used for overcurrent and LED 4 for negative-sequence overcurrent protection
operate indication. LED 4 is also u | PLC电路板 DSDI110AV1 3BSE018295R1 | | | |
