Figure 525: Frequency protection function
General start and operate signals from all functions are connected to minimum pulse
timer TPGAPC for setting the minimum pulse length for the outputs. The output from
TPGAPC 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.
