4.5 Alarm
Delays
•
■ Alarm Delays
• Delays can be set for the alarm outputs. ON and OFF delays can be
set separately for alarms 1 and 2. The ON and OFF delays for
alarms 1 and 2 also apply to the individual ALM1 and ALM2
indicators. The alarm ON delays will also function when the power is
turned ON.
● 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.
