General information
The unit is made of a service board and a separate power board which are linked with a ribbon
cable. Both parts form a complete installation unit. All outputs and inputs are connected on the
back of the power board. The unit fulfils the function of a temperature controller with timer function
and is cut to the use with deep-fryers.
On the front of the unit has a 4-digit 7-segment LED display, 6 keys and 6 LEDs. 3 LEDs identify
the selected temperature setpoint relevant for the regulation (“temperature 1, 2, 3”), 1 LED shows
the status of the timer (“time 1”) and the remaining 2 LEDs indicate the heating mode (“TURBO”)
and the present status of the control output (“HEAT”). During the timer expires the LED “time 1”
flashes, during careful heating the LED “TURBO” flashes. If the LED “TURBO” is off the unit
regulates with PID characteristics and approaches the setpoint preventing extreme oscillating. If
the LED “TURBO” lights up permanently thermostatic regulation and therefore the utmost heat
supply is active.
A temperature sensor is connected to measure the actual value. Be means of parameter it is
possible to select among Pt100, Pt1000 and PTC as sensor type without circuitry adaptations. Two
switching inputs – if available – permit the start of the timer with an external switching key and the
activation of a setpoint reduction, which is indicated by a flashing point on the right side of the
display. The function of the switching inputs can be deactivated with parameters.
The output relays are two change-over contacts. The functions “heating”, “control contact 2” or
“alarm” can be assigned to each output, even the deactivation of a output is possible.
The controller has the possibility of a particularly careful heating in case the deep fryer fat is not yet
melted. This retarded heating process (Melt-function) is always activated after switching no the unit
and ends if an adjustable limit value below the setpoint is reached. If the fat is evidently melted you
can switch to accelerated heating by pressing the “TURBO” key even before the limit value is
reached. During cooling the turbo-mode remains active until the temperature falls below 50 °C.
Then the reloading of solid fat is assumed and the controller switches back to reduced heating
automatically. The reduced heating mode can be deactivated.
Two adjustable limit values provide a temperature alarm relative to the control setpoint. Boundary
and range alarm as well as relative and absolute limit values are possible.
In these alarm cases the control process continues. An internal buzzer provides an
acknowledgeable alarm signal..
An operating time recording monitors the fat temperature and counts the operating hours with
actual values above an adjustable limit value. An alarm message can be activated or a regulation
blocking takes place (if activated) to force replacing the deep fryer fat. A reset is only possible in
alarm or blocking condition, in addition temperature must fall below a further adjustable limit value.
If a regular exchange of the fat is guaranteed otherwise, an unconditional reset of the fat operating
time can be enabled by means of parameters.
