Customer-specific table
In this mode, you can use the optionally available setup program (no entry can
be made on the device) to create a customer-specific characteristic line in the
form of a table with up to 20 pairs of resistance/temperature values for the
analog temperature input. NTC and PTC characteristic lines are possible; they
must be monotonous.
Max./min. value memory
This memory stores the minimum and maximum input values. This information
can be used to evaluate whether the connected sensor is designed for the
actually occurring values, for example.
The max./min. value memory can be reset: Operator level / Display / MIN/MAX
RESET / Yes, see "Operator level parameters", page 96ff.
Special controller functions:
The following functions can be activated in this menu:
• Manual mode (activate controller outputs manually) – see chapter 6.10.4
"MANUAL/simulation overview", page 40
• Isolated controller (see below)
• I-proportion switch-off (see below)
Isolated controller
This function is normally deactivated (default settings or "no" selected).
In the deactivated state, the software prevents two controller outputs from
working "against each other". This means that simultaneous dosing of acid
and lye is not possible.
If the controllers are isolated ("yes" selected), both controllers are freely con-
figurable.
I-proportion switch-off
This function is normally deactivated (default settings or "no" selected).
In the deactivated state, the controller operates according to the general con-
troller theory.
If I-proportion switch-off is activated ("yes" selected), the share of the output
level to which the I-proportion is attributed is set to zero when the setpoint
value is reached.
This may beneficial for mutual neutralization (acid and lye dosing possible) in
one treatment tank.
