When the cursor is on one of the alarm modes press ENT to change
the numerical values associated with that alarm. Select from the
values of 25, 50, 100, 150, 200, 300, and 400. These values are the
range from the set point that will trigger an alarm. Press the ENT
again to move to the next set ORP item.
Alarm defaults: Min: 400 / Max: 750.
The controller has factory defaults which will issue alarms when
these values are exceeded.

Use arrow keys to cycle these selections.
If the lockout time is greater than 10 the lockout function is active.
The controller will then “lock out” output after the selected time has
elapsed without the controller having reached its nominated set
point for ORP. This is a safety feature to prevent overdosage in
case of sensor failure.
