10.9.3 Adjusting PID Settings
ATTENTION
Inappropriate changes to the PID controller settings may have a
negative effect on the fermentation/cultivation process and
cause loss of property.
Therefore, only change factory settings of the PID controller(s),
if you are fully aware of the consequences or after consulting
the manufacturer!
PID control may be configured for parameters
pH
,
pO
2
and
Pump4
(Function
Balanced Feed
). This is done in the editor menu of the
corresponding parameter and therefore described there.
10.10 Alarms – Equipment Alarm Menu
There are two types of alarm that appear in the
Equipment Alarm
menu:
Parameter alarms
Display of deviations from actual values
and setpoints for parameters after a predefined waiting time.
Also see the “Parameter alarms” section.
Equipment errors:
If equipment errors occur repeatedly or
cannot be resolved, inform an authorised INFORS HT service
partner. Also see the fault table in the “Interferences” section.
The
Equipment
Alarm
menu is only available when there are open
or unconfirmed alarms. Otherwise the alarm symbol (a red excla-
mation mark highlighted in white on a red background) is hidden in
the lower screen edge.
