In addition to setting the temperature value, the
buttons
UP
and
DOWN
perform other functions, too.
Pressing the
UP
for 3 seconds will trigger a non-
standard defrosting operation of the refrigerating
plant. In the case of an alarm (with buzzer triggered),
the
DOWN
button can be used for acknowledging the
buzzer sound.
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.
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.
