Special Condition Handling
Overlapping timer events
If a second timer event occurs while the first one is still active, the second event will be ignored. An Event Skipped
alarm will be set.
Interlock Conditions
Interlocks override the relay control, but do not change the operation of the timer control.
A digital input or output interlock condition does not delay the relay activation. The relay activation duration timer
will continue even if the relay is deactivated due to an interlock condition. This will prevent delayed events which
can potentially cause problems in they do not occur at the correct time.
“Activate With” Conditions
“Activate with channels” settings override the relay control, but do not change the operation of the timer control.
The relay activation duration timer continues counting when the timer relay is forced on, and ends at the expected
time (event start time plus duration). If the “activate with” condition continues after the end of the event time, the
relay remains activated.
Alarms
An Event Skipped alarm is set when a second timer event occurs while one event is still running.
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
“activate 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, alarms related to this output, current cycle on time, relay type and the current control mode setting. The cur-
rent 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 timer cycle.
Settings

Event 1 (through 10)
Enter these menus to program timer events via the menus below:
Repetition
Select the time cycle to repeat the event: Hourly, 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.
Events Per Day
Only appears if Repetition is Hourly. Select the number of events per day.
The events occur on the Start Time and then evenly spaced throughout the
day.
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 that will be washed.
Input 2
Select the second sensor, if applicable, that will be washed.
Sensor Mode
Select the effect that the probe wash event will have on any control outputs
that use the sensor(s) being washed. The options are to either Disable the
sensor readings (turn the control output off) or Hold the sensor reading at
the last valid sensor reading prior to the start of the probe wash event.
