Controller for cooling applications – programming instruction
PARAMETERISATION
Parameterisation of the cooling controller is done in the
factory or during commissioning of a cold store by
qualified staff. Wrong or inappropriate parameterisation
can result in malfunction and damage of the
refrigerated goods. Parameter setting is possible only
after entering one or more passwords. In the following
list of parameters, all parameters of a complex cooling
controller are listed. Please note, however, that the
parameters listed are only available in controller designs
where the relevant hardware (outputs, inputs, sensors
and internal clock) is available.
Parameterisation is possible at any time. The control
operation is not interrupted during parameterisation,
but can have a direct influence on it. If no button is
pressed for 2 minutes, the operation is stopped and the
actual value is displayed again.
To activate parameterisation mode, press buttons UP
and DOWN at the same time. After approx. 3 seconds,
the code word will be displayed.
Press UP or DOWN to switch between code words ,
,and . All other settings / value
specifications in parameter setting mode are performed
using the default value setting method, i.e. pressing
buttons SET and UP / DOWN at the same time.
NETWORK ADDRESS
Under code word you can set a network address.
This is required for commissioning networked systems.
ENTERING A PASSWORD
By selecting code word you can enter a password
required for parameterisation. Once the password has
been entered , the name of the first group of
parameters is displayed (alarms). Now, using the
buttons UP and DOWN you can select any of the
parameter groups quickly.
PRE-DESIGNED PARAMETER SETS
With this parameter (by selecting code word and
entering password ), you can set up pre-defined data
sets. The data sets are provided by Störk-Tronic. If a
new data set is loaded, all previously set parameters will
be overwritten. After that, they can be edited as
required.
USER LEVEL
By selecting code word and entering the correct
password , a list with some predefined parameters
is opened. These parameters are:
, , , , , , , and .
ALARMS
Once you have selected a parameter group, it will
normally be sufficient if you press the button SET (
will be displayed) and then release the button again.
Now, the first parameter of the group will be displayed
(parameter in parameter group , for example).
Using the buttons UP and DOWN you can scroll the
parameter group and change certain parameter values
using the default value setting method. Press buttons
UP and DOWN at the same time to quit any parameter
group and return to the list of parameter groups. To quit
the list of parameter groups and return to the standard
level, press buttons UP and DOWN at the same time.
In some cases, certain parameter groups may be
protected by a password. In this case, you will have to
enter a specific password for the parameter group like
in the case of activation of the parameterisation level.
