Alarm Delays

• Delays can be set for the alarm outputs. ON and OFF delays can be set separately for alarms 1, 2, 3,
and 4. The ON and OFF delays for alarms 1, 2, 3, and 4 also apply to the individual SUB1, SUB2,
SUB3, and SUB4 indicators and to communications status. The alarm ON delays will also function
when power is turned ON or when moving from the Initial Setting Level to Operation Level (e.g., to
software resets). All outputs will turn OFF and the OFF delays will not function when moving to the
Initial Setting Level or when an alarm is output for an A/D converter error.
Operation of Alarm ON and OFF Delays (for an Upper-limit Alarm)
• The alarm will not turn ON if the time that the alarm is ON is equal to or less than the ON delay set
time. Also, the alarm will not turn OFF if the time that the alarm is OFF is equal to or less than the
OFF delay set time.
• If an alarm turns OFF and then back ON during the ON delay time, the time will be remeasured
from the last time the alarm turns ON. Also, if an alarm turns ON and then back OFF during the
OFF delay time, the time will be remeasured from the last time the alarm turns OFF.
