The alarm is normally OFF if upper- andlower-limit values of hysteresis overlap.Set value: 5 upper- and lower-limit alarm with standby sequence. For the above upper- and lower-limit alarm:• In cases 1 and 2, the alarm is normally OFF if upper- and lower-limit values of hysteresis overlap.• In case 3, the alarm is normally OFF.Cases 1 and 2 example:Publication 900-UM003C-EN-E - January 2004
