Ineffective Control Lockout
The Bluelab pH Controller continually checks to ensure that dosing is having an effect.
It will go into lockout if 15 dosing cycles do not move the pH value by at least 0.1 pH in
the desired direction. This is called the ineffective control lockout, and is enabled by
default, but can be disabled via Edenic.
The Bluelab pH Controller will indicate it is in ineffective control lockout by flashing the
display and displaying ‘HELP Ineffective Control’.
IMPORTANT
The ineffective control lockout is useful to stop dosing if pH solution tanks have
emptied, or a hose has fallen out of a reservoir, for example.
However for a batch dosing system where fresh water is being added to the
reservoir at the same time as dosing is occurring, it may be better to disable this
feature.
