Figure 128: Residual voltage protection function
The MSVPR1_27R-1 function is used to monitor the remanent voltage over a decaying
frequency after power supply is lost, before allowing connection of backup power. It
provides a permissive signal indicating when connecting of backup power can be
completed safely.

Figure 129: Three-phase remnant undervoltage protection function
General pickup and trip signals from all functions are connected to minimum pulse timer
TPGAPC1 for setting the minimum pulse length for the outputs. The output from
TPGAPC1 can be connected to binary outputs. However, these are not connected in the
configuration.
If a new protection function block is added to the configuration, check the
activation logic and add connections.
