“Activate With” Conditions
“Activate with channels” settings override the relay control, but do not change the operation of the timers or
related bleed control. The biocide timer continues counting biocide add time when the biocide relay is forced on,
and ends at the expected time (biocide event start time plus duration). If the “activate with” condition continues
after the end of the biocide feed time, the relay remains activated.
Alarms
An Event Skipped alarm is set when a second biocide event occurs while one event is still running (either in
prebleed, biocide add or post-biocide add lockout).
An Event Skipped alarm is also set when the biocide add relay never turns on during a biocide add 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
current week number and day of the week is displayed (even if there is no multi-week repetition event pro-
grammed). Cycle Time shows the time counting down of the currently active part of the biocide cycle (pre-bleed,
biocide feed, or post biocide feed lockout of the bleed).
Settings
Touch the Edit icon to view or change the settings related to the relay.
Event 1 (through 10)
Enter these menus to program timer 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.
Bleed
Select the relay to be used for Bleed/Blowdown
Prebleed Time
If lowering the conductivity prior to feeding biocide is desired using a fixed
time instead of a specific conductivity setting, enter the amount of time for the
prebleed. Also may be used to apply a time limit on a conductivity based
prebleed.
Prebleed To
If lowering the conductivity prior to feeding biocide is desired, enter the
conductivity value. If no prebleed is required, or if a time-based prebleed is
preferred, set the conductivity value to 0.
Cond Input
Select the sensor to be used to control the prebleed relay selected above.
Bleed Lockout
Enter the amount of time to lockout bleed after the biocide feed is complete.
Add Last Missed
Select Enabled if the controller should delay start the most recent Biocide cycle
until immediately after an Interlock clears, or Disabled if all Biocide feed should
be skipped if there is an Interlock condition at the time the add was due to start.

or Control Outputs, Alarm Output Mode
Output Details

time, alarms related to this output, current cycle on time, relay type and the current control mode setting.
