Figure 241: Operating effect of the BLOCK input when the selected blocking mode is
“Freeze timer”
If the BLOCK input is activated when the trip timer is running, as described in Figure 223,
the timer is frozen during the time BLOCK remains active. If the timer input is not active
longer than specified by the Reset delay time setting, the trip timer is reset in the same way
as described in Figure 221, regardless of the BLOCK input.
The selected blocking mode is “Freeze timer”.
