The functional diagrams describe the default input, output, programmable LED, and function-to-function connections of default configuration. The default connections can be viewed and changed with PCM600 according to the application requirements, if necessary.
The analog channels, measurements from CTs and VTs have fixed connections towards the different function blocks inside the relay's default 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 phase currents to the relay are fed from Rogowski or combi sensors. The residual current to the relay is fed from either residually connected CTs, an external core balance CT, neutral CT or internally calculated. The phase voltages to the relay are fed from combi sensors. The residual voltage is internally calculated.
The relay offers six different setting groups which can be set based on individual needs. Each group can be activated or deactivated using the setting group settings available in the relay.
There are 16 programmable push buttons offered in the front panel of the unit. The relay offers six different setting groups which can be set based on individual needs. Each group can then be activated or deactivated by using a programmable button. In addition to this, the programmable button can also be used, for example, for the manual trigger of disturbance recorder, enabling/disabling the autoreclosing function, circuit breaker control interlocking bypass or master trip lockout reset.
