5. Operation
5.1 General Hints and Tips
IMPORTANT:
Before starting operation, all the controller's parameters should be adjusted to suit
the system requirements.
Wrongly set parameters can lead to serious operational disruptions !
There follows a description of all the stages necessary for programming the various
controller configurations. Depending on the configuration, some parameters are hid-
den.
IMPORTANT:
When designing a control system, you should consider the consequences of a mal-
function. For example, in the case of a temperature control system there is the pos-
sibility of a heating unit not cutting out, leading to the possibility of injuries to persons
or damage to equipment. Protect yourself and your equipment by additional protec-
tive measures.
TIP:
We recommend you to note the values set on the controller before delivery to the
end user. In this way it is possible for you to deliver a pre-programmed controller in
the event of a spare part delivery.
When changing the controller at the end user's establishment, you will then only
need to re-set the actual value correction.
TIP:
In the standard setting, only the setpoint temperature C1 can be directly changed in
the operating level. When programming the different set temperatures, it is therefore
necessary to consider which setpoint temperature must be corrected most frequently
by the end user.
In the extended working level setting, the plant engineer can release further para-
meters of the setting level for the end user to view or modify.
TIP:

The configuration software available as an option can be used to set and update the
temperature controller's parameters. The values measured by the three sensors, the
analogue input and the analogue output control signal can also be transmitted to a
PC.
