If additional nominal values or aggregate buttons
(e.g. FC-value, Delta temperature, optional
regulators)
have been enabled, the relevant nominal and actual values are displayed in operating
mode and can be changed transiently.
Be aware
If you change a nominal value while a step is running, then this value applies only for the
duration of the current step. The value is not saved and is only valid until the step ends. If
you want to save nominal values permanently you have to change them in
„Programming
mode
“ p.21.
8.1.1 Aggregate and relay display
On the status bar all relays and their states are shown.
8.1.2 Aggregate modules
If aggregate modules have been enabled, you can influence them. Types of modules available,
options for entering values and the unit scale in which these values are entered, all depend on
the configuration and are determined by the manufacturer. Please ask your service technician
for further information.
Be aware
These changes are only valid in the current step. They are not permanently saved and only
apply until the end of the step!
8.1.3 Optional control loops
The nominal values of the optional control loops
(if configured by a service technician) can be
pre-set individually in the program steps.
If additional control loops or additional sensors have been configured for the process that is
currently in operation, they will be displayed together with their current temperature values
(actual values).
8.2 Switching into a different step
In order to switch into a different step, two conditions must be fulfilled in the configuration:
There must be at least one step activated in a program under number of steps. (Please ask
your service technician about this.)
Prog.no must be enabled on the status bar, this ensures that the information for the current
program and step are shown during operation.
(Setting up the status bar, please see next item 8.3)
