Blocking mode is the setting that determines how all blocking signals to the device will
behave.
- Blocking Inactive Mode: When this selection is activated, the guards in the device are not
blocked.
- Freeze Counting Mode: When a blocking signal is received to the device, the guards keep
the time counted up to that time and continue to count when the blockage is removed.
- Reset Count Mode: When a blocking signal is received to the device, the time counted by
the guards is reset and starts from the beginning when the signal disappears.
- Resume Count Mode: When a blocking signal is received to the device, the guards continue
to count the duration but do not create a Trip. When the blocking signal is removed and
expires, they form an opening immediately.
