An Event Skipped alarm is also set when the timer relay never turns on during an event because of an interlock
condition.
The alarm is cleared when the relay is next activated for any reason (the next timer event or HAND mode or “acti-
vate with” force on condition).
Output Details
The details for this type of output include the relay on/off state, HOA mode or Interlock status, accumulated on-
time, current cycle on time, relay type and alarms. The current week number and day of the week is displayed
(even if there is no multi-week repetition event programmed). Cycle Time shows the time counting down of the
currently active part of the cycle.
Settings
Press the Settings key view or change the settings related to the relay.
Set point
Enter the sensor process value at which the relay will activate.
Spike Set point
Enter the sensor process value at which the relay will activate during the Spike
Event time.
Deadband
Enter the sensor process value away from the set point at which the relay will
deactivate. The same Deadband is used for the normal Set Point and the Spike Set
Point.
Onset Time
The onset time determines when the duration timer starts. If set to zero, the dura-
tion time starts immediately. If set higher than that, the controller will not start the
duration timer until the spike set point is achieved, or until the onset time is over,
whichever comes first.
Duty Cycle Period
Using a duty cycle helps to prevent overshooting the set point in applications
where the response of the sensor to chemical additions is slow. Specify the amount
of time for the cycle, and the percentage of that cycle time that the relay will be
active. The relay will be off for the rest of the cycle, even if the set point has not
been satisfied.
Enter the length of the Duty Cycle Period in minutes:seconds in this menu. Set the
time to 00:00 if use of a duty cycle is not required.
Duty Cycle
Enter the percentage of the cycle period that the relay will be active. Set the
percentage to 100 if use of a duty cycle is not required.
Event 1 (through 8)
Enter these menus to program spike events via the menus below:
Repetition
Select the time cycle to repeat the event: Daily, 1 Week, 2 Week, 4 Week, or None.
An event means that the output is turned on at the same time of day, for the same
amount of time, and except for the Daily cycle, on the same day of the week.
Week
Only appears if Repetition is longer than 1 Week. Select the week during which
the event will occur.
Day
Only appears if Repetition is longer than Daily. Select the day of the week during
which the event will occur.
Start Time
Enter the time of day to start the event.
Duration
Enter the amount of time that the relay will be on.
Input
Select the sensor to be used by this relay.
Direction
Select the control direction.
