CONFIGURATION OF DELAY TIMES ON THE CONTACTS PORT
Another configuration inserts a relay switching delay of approximately 8s from the
activation of the command signal. The delay may be useful for filtering brief unwanted
signals such as sudden mains blackouts, switching to bypass due to distorting loads,
etc. The default configuration and the association between the signals and jumpers are
shown in Table 2. The delay is active when the jumper is closed.
