The time of ON-delay alarm or timer function
[Description]
ON-delay alarm
•With this function, the alarm relay is closed after the pre-
determined delay time. (See operation q shown in the
figure below.)
• In case the cause of the alarm is solved within the delay
time, the alarm relay is not closed. (See operation e shown
in the figure below.)
•The alarm relay is opened regardless of this parameter.
(See operation w shown in the figure below.)
• In case the alarm is set to OFF during standby, the ON-
delay operation performs again when returning to RUN.
•When the delay time is changed during ON-delay opera-
tion, the alarm is activated in the changed delay time.
Timer function
•When the ON-delay timer is selected (ALMn = 32), the re-
lay is closed in the set time after DI input is set to ON. While
the DI input stays OFF, the timer cannot be activated.
• When the OFF-delay timer is selected (ALMn = 33),
the timer cannot be activated while the DI input is set to
ON. The relay is closed in the set time after DI input is
set to OFF.
• When the ON/OFF-delay timer is selected (ALMn = 34),
the timer is activated while the DI input stays either ON
or OFF.
•The timer display function shows the remaining time of
timers 1, 2 and 3.
•The set time is counted down while the ON or OFF timer is
activated.
•
While the ON timer is activated, the alarm relay is closed
when the remaining time is 0. While the OFF timer is acti-
vated, the alarm relay is opened when the remaining time is 0.
