Configuration, Operating Mode, and Blocking of the Output
Relays (Function Group OUTP)
The P631 has output relays for the output of binary signals. The binary signal
assignment is freely configurable by the user.
Configuration of the Output Relays
One binary signal can be assigned to each output relay. The same binary signal
can be assigned to several output relays by configuration.
Operating Mode of the Output Relays
The user can set an operating mode for each output relay that determines
whether the output relay operates in a normally open arrangement (NO) or
normally closed arrangement (NC) and whether it operates in latching mode.
Depending on the selected operating mode, latching can be disabled, either
manually using a setting parameter or by an appropriately configured binary
signal input at the start of a new fault, signalized by the onset of a general
starting, or of a new system disturbance.
Blocking the Output Relays
The P631 offers the option of blocking all output relays via a setting parameter or
by way of an appropriately configured binary signal input. The output relays are
likewise blocked if the device is disabled via appropriately configured binary
inputs.
In these cases the relays are treated according to their set operating mode, i.e.
relays in a normally open arrangement (NO) are not triggered, whereas relays in
a normally closed arrangement (NC) are triggered.
This does not apply to the relays associated with the signals SFMON: Warning
(relay) or MAIN: Blocked/faulty. Self-monitoring alarms are thus correctly
indicated.
If the self-monitoring detects a serious hardware fault (see error messages in
, which will lead to a blocking of the protection), all
output relays are reset regardless of the set operating mode or signal
configuration.
