General information
GENERAL NOTES
The ST……209 controllers are designed for
general use in deep fryers.
Depending on the existing hardware, up to
four temperature sensors can be connected.
The type, function, offset and weighting of
each sensor can be configured separately
via parameters. Additionally, two analogue
inputs (4...20mA and 0...10V) can be made
available.
The max. six digital inputs can also be con-
figured separately, depending on the hard-
ware installed. Possible functions include:
heater alarm, recipe start, or several basket
functions.
Depending on the hardware, up to six relay
outputs are possible the functions of which
can be configured as required via parame-
ters. Please refer to the specifications of the
hardware installed to ensure that the relays
are not overloaded. Also refer to the circuit
diagram in the corresponding device man-
ual.
All parameters can also be accessed via the
RS485 interface.
CONTROL KEYS
The controller can be equipped with up to 7
control keys.

Key T1: UP
By pressing this key, the parameter
or parameter value is increased. A
further function of the key can be set with
parameter
b1
.
Key T2: DOWN
By pressing this key, the param-
eter or parameter value is de-
creased. A further function of the key can be
set with parameter
b2
.
Key T4: SET
While this key is pressed, the set-
point is indicated. The function of
the key can be set with parameter
b4
(un-
changeable in this case)..
Key T7: Standby
The function of the key can be set
with parameter
b5
. It is preset as
standby key. Thus the unit can be switched
on or off (no mains disconnection).
The controller is generally operated using
the buttons UP, DOWN and SET. The stan-
dard display indicates the actual tempera-
ture value. Press the SET button to switch
over the display to the setpoint temperature.
The setpoint temperature can only be
changed by pressing buttons SET and UP
or SET and DOWN at the same time. While
pressing the buttons, the changing setpoint
temperature is displayed. After changing
the setpoint temperature and releasing the
buttons, the actual temperature is displayed
again. This is the standard setting method.
If you press the STANDBY button during
operation (for at least 3 seconds), the con-
troller is switched off and the message
OFF
will be displayed. To switch on the controller
again, press the STANDBY button again.
In addition to setting the temperature value,
the buttons UP and DOWN can perform oth-
er functions, too. In the case of an alarm, the
DOWN button can be used for acknowledg-
ing the buzzer sound.
PARAMETERISATION
Parameterisation of the cooling controller is
done in the factory or during commissioning
by qualified staff. Wrong or inappropriate pa-
rameterisation can result in malfunction and
damage of the goods.
Parameterisation is possible at any time. The
control operation is not interrupted during
parameterisation, but can have a direct in-
fluence 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
ADR
. will be displayed. Press UP or DOWN
to switch between code words
Adr
,
PA
and
USR
. 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
.
Adr
NETWORK ADDRESS
The code word
Adr
allows you to set a
network address. This is mandatory for the
commissioning of networked systems.
PA
ENTERING A PASSWORD
By selecting code word
PA
, you can enter
a password required for parameterisation.
Once the password has been entered, the
name of the first group of parameters is dis-
played
A--
(alarms). Now, using the but-
tons UP and DOWN you can select any of
the parameter groups quickly.
USr
User level
Some frequently used parameters can be
placed in the user level, so that they can be
accessed more quickly.
A--
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
A0
in parameter group
A--
, 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 parame-
ter group and return to the list of parameter
groups. To quit the list of parameter groups
and return to the standard level, press but-
tons 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 pass-
word for the parameter group like in the case
of activation of the parameterisation level.
