Design, function and parameterisation
The device is designed as a complete built-in unit and for rear installation. The new capacity keypad enables
a smooth glass front and makes the device particularly suitable for applications with a high degree of soiling.
All inputs and outputs are connected from the rear side. The device is as a temperature controller with timer
functions and is designed for use with deep fryers.
The front of the device is provided with a three-digit and a four-digit display, eight control buttons and twelve
LEDs. Five LEDs indicate the reference temperature selected for the control operation ("TEMPERATURE 1,
2, 3, 4, 5"), five LEDs indicate the time selected for the timer ("TIME 1, 2, 3, 4, 5") and another one indicates
the current status of the control output ("HEAT"). The LED at the Melt/Turbo button signals the selected
operating status. If it is on, gentle heating is activated. This behaviour can be reversed with parameter P17.
For determination of the actual temperature, a temperature sensor type Pt100 or a thermocouple is
connected. Two switching inputs enable external starting and stopping of the timer and connection of an
overtemperature signal contact. In case of overtemperature "UEb" or "Hot" will flash on the display and the
controller will be turned off. Function of the switching inputs can be deactivated via the parameterisation.
Four make-contacts and one change-over contact are provided as output relays. Via the parameterisation,
you can select function Heat Thermostat 1 or Heat PID, you can also deactivate the output. Output K2
performs the basic function Cool Thermostat 2 and can be used for a release function. Output K3 controls
lowering of the basket, output K4 controls raising of the basket. This also applies in the case of a temporary
stop of the timer. Output K7 is assigned to the limit value alarm.
The controller features a gentle heating function which is activated as long as the frying fat is still congealed.
This slow heating process (melt function) is active each time the system is turned on and will be deactivated
as soon as an adjustable temperature threshold below the selected fat temperature is reached. Via the
"TURBO" button, accelerated heating can be activated before the threshold is reached if the fat has melted
visibly. After cooling, turbo mode will remain active at first. As soon as the temperature drops below 50 °C, it
is assumed that unmelted fat is reloaded and the controller activates the melt function automatically.
You can also enter a variable frying time. Taking a parameterisable weighing factor into account, the time of
the started timer is increased or reduced dynamically, depending on the control deviation.
A threshold couple which can be adjusted during parameterisation, enables a temperature alarm, referred to
the actual value. Both relative and absolute thresholds can be selected. If these alarms are triggered, the
control operation is continued. An internal buzzer enables an acknowledgeable warning signal.
Parameterisation mode can be activated by pressing the Temperature Up and Temperature Down buttons
simultaneously for 3 seconds. Parameter "P1" appears in the display. Use the Up and Down buttons to scroll
through the parameters. To access higher parameters quickly, scroll backwards using the Down button.
Press the Melt-Turbo button to activate the value of the current parameter, the digit which can be changed
will be flashing. Use the temperature selection button to select other digits. Once, you return to "P1",... the
changed value is saved. Now, you can return to normal mode by pressing Up+Down. After 60 seconds, the
controller returns to normal mode automatically without saving any changes.
