There are two buttons on AlarmSet menu: alarm concentration and
automatic recovery.
• Alarm concentration: Here you can set the concentration
for triggering a low and high alarm. (Figure 4.33)
• Automatic restoration: Here you can set whether the
alarm relay restores automatically after the alarm is
cleared as well as the corresponding restoration time. The
alarm relay restoration time is the time it takes for the
alarm relay to return to the non-alarm or closed state.
