5.7 Parameter levels
The operation of the controller is carried out in different operating levels:
Auf The display permanently shows the temperature as currently measured.
The “SET“ button can be used to display and, in conjunction with the arrow buttons,
to change target temperatures that have been set. See parameter [d6] for how to
adjust the function of the SET button.
NB: Target temperatures can be changed here only if the button lock [C99] is set to
'0' in the programming level.
The plant engineering company has the ability to share the customer additional pa-
rameter setting level to view or to change. The setting for this can be found in the
parameters [d6, d7, d8].
The programming level contains the parameters which the end user must be able to
adjust during subsequent operation.
Configuration level
[P parameters]
The configuration level is used for programming the basic functions of the controller.
As subsequent interference by the end user (after configuration) can result in dan-
gerous changes that are not immediately apparent, access to the configuration level
is made more difficult by means of coding (level codes).
Option level
[H parameters]
The option level is used to programme additional controller functions such as deter-
mination of alarms, functions of digital inputs, button functions, etc..
This is where the controller hardware is configured.
(Number and type of sensor inputs, determination of analogue input and output, in-
terface monitoring speed, etc.)
Working level
... is for everyday operation by the end user.
Programming level
... for setting the regulatory parameters (C-parameter).
Configuration level + Option level
... for setting the basic functions
and programming of additional settings (P- / H- parameter).
Hardware configuration
... for configuration of controller hardware (D- parameter).
