Function
The profile controller operates with three microcontrollers (1) which supervise
the program sequence, control action, operation and display.
Included are EPROMS as read-only memory (2) and RAMs as read/write memory (3). The user programs are held in a non-volatile flash EPROM (4).
Version LPF-200 includes a real-time clock (5).
Inputs such as configuration, operation etc. are made using 24 keys on the
LPF-100 (6), and more conveniently using 38 keys on LPF-200 (6), in part the
inputs can also be made from a PC through the SETUP interface (7).
All the relevant values are shown on the LPF-100 on 17-place 7-segment displays and 25 LEDs (8), on the LPF-200 on 30-place 7-segment displays (8) in
two colours together with 35 LEDs.
The data exchange between process unit and operating unit takes place in the
case of the compact unit via the 78kbaud LON interface DC (9), and with separate units via the 78 kbaud LON transceiver FTT-10 (10).
The analogue values of the transducers (11) are processed and digitised in
ASIC circuits (12).
Four external inputs (13) are available for remote operation and inhibition of instrument functions.
12 or 24 relay outputs (14) with contact protection circuit are provided.
On the compact unit the supply for the instrument is obtained from a switchmode supply (15). In the split version the operating unit incorporates an additional power supply (15) which must be connected up separately.

Installation notes
- The choice of cable, the installation and the electrical connection of the instrument must meet the requirements of VDE 0100 “Regulations on the Installation of Power Circuits with nominal voltages below 1000V” or the appropriate local regulations.
- Work on the instrument must only be carried out to the extent described
and, like the electrical connection, only by properly qualified personnel.
- Isolate the unit on line and neutral from the supply if there may be contact
with live parts during work.
- The external fuse of the supply should not be rated above 10 A (slow).
The load circuit should be fused for the maximum relay current in order to
prevent welding of the output relay contacts in case of an external shortcircuit.
- Electromagnetic compatibility conforms to the Standards and Regulations
specified under Technical Data. Setup interface and inputs are not isolated,
v Data Sheet.
- The instrument is not suitable for installation in hazardous areas.
- Input, output and supply lines should be run separately and not parallel to
each other.
- Sensor and interface lines should be screened and twisted together.
Do not run them close to current-carrying components or cables.
Temperature probes should have the screen grounded at one end at the
instrument terminal TE; the LON interface should be grounded at both ends
(at each unit).
- If there is no technical earth in the installation, connect terminal TE on the
instrument to the potential earth (PE).
- Do not loop the earth connections, i.e. do not run them from one instrument
to another; run them singly, e.g. to earth terminals on the rail (short leads!)
- Do not connect any further loads (relays) to the supply terminals of the
instrument.
- Apart from unsatisfactory installation, incorrect settings on the instrument
(setpoint, data at configuration level) may interfere with the proper operation of the controlled process or result in damage. Provision should therefore always be made for safety devices independent of the instrument, e.g.
overpressure valves or temperature limiters/monitors. Setting up must be
restricted to properly qualified personnel. Please observe the appropriate
safety regulations in this connection. Adaptation (self-optimisation) cannot
be expected to handle all possible control loops so that there is theoretically a possibility of setting unstable parameters. The final process value
should therefore be checked for its stability.
- Setup interface and inputs are not isolated.
- If any inputs are carrying a voltage, the corresponding connectors have to
be pulled off before the setup operation.

Connection of Series mTRON instruments
The profile controller can be looped into a network with modules of the
JUMO mTRON automation system. When there is a separate operating unit,
there are two “nodes” which have to be wired up as described below.
The connections are on the back of the unit. A screened twisted pair is used as
transmission line in the JUMO mTRON automation system; it has to meet the
following specification:
Characteristic impedance 100 — 120Ω, capacitance approx. 60pF/m.
The connection can be made as line, ring or star structure (free topology).
Relay module
Line structure
20
The physical bus ends are provided at both ends with a termination resistance
of 100 Ohm which is activated by a switch on the module.
At a data rate of 78 Kbaud this results in a typical network of 2700m.

5.1
Profile programs
Up to 99 profile programs (1—99) with up to 99 segments can be programmed
for chamber temperature and humidity, a freely assigned extra temperature
and various cooking processes.
5.1.1 Setpoints and segment times
Each segment carries a process step (e.g. “B”) with the setpoints for the temperatures, the cooking process and the segment time. In addition it is possible
to input operating functions separately for each segment. The limit comparators are active throughout the entire profile program.
5.1.2 Operating functions
Activated operating functions can be used to control fans, flaps and valves. An
operating function can have only one status during a segment, and/or one pulsing action if this is configured.
v Section 6.1.3 “Switching action of the operating functions”
The number of operating functions and their assignment depends on the instrument version.

5.1.3 Step-on conditions
Stepping on to the next segment during the profile run depends on several
conditions which are laid down when the profile program is input. These stepon conditions can be combined with each other. The start of the next segment
is initiated by the first step-on condition to fulfill the step-on requirements.
The profile steps on when...
- the set segment time has elapsed;
- the set core temperature has been reached;
- the set F-value or C-value has been reached;
- if F-value or C-value setpoint has been programmed together with the core
temperature setpoint, when both setpoints have been reached;
- if an external input has been configured so that it initiates stepping on to
the next segment; v Section 6.1.11 “Logic inputs”
- when the key c on the operating unit is pressed.
H
De-activating the step-on conditions:
Input (- - -) for setpoint or core with the Skey,
input (0 0 0) for segment time, F or C .
5.1.4 Process steps
The equipment manufacturer normally pre-defines up to 99 process steps in
the profile controller. During input of the profile program, each profile segment
must have a process step assigned to it consisting of chamber temperature,
humidity, core temperature, delta value, final F-value, final C-value, segment
time and operating functions. The more important processes are marked as
letters on the number keypad (e.g. “B”). Additional processes up to No. 99 can
be input through the number keys.
The process steps contain setpoints and operating functions.
A process step must be selected for each profile segment and also for manual
operation.

5.1.5 Delta cooking
Delta cooking is possible both during heating and during cooling. The temperature difference (delta value) can be selected.
Heating
Fig. A:
Here the chamber temperature setpoint is raised by 20°C parallel to the actual
core temperature until the desired chamber temperature is reached. The core
temperature then rises up to the set core temperature setpoint and the controller then switches to the next profile segment.
Cooling

If the chamber temperature setpoint is below the core temperature setpoint,
cooling takes place in a similar manner.

5.1.6 F-value cooking
The calculation of the F-value (bactericidal factor) is based on the time during
which a temperature acts on the product and is derived from a table for
10°C
F
cooking.
70°C
The subscript value 70°C is the reference temperature. At a core temperature
of 70°C and an action time of 1 min the product reaches an F-value of 1.
The superscript value 10°C (= time-temperature relationship of bactericidal
action) means that every temperature increase by 10°C increases the F-value
10fold.
The F-value is calculated at a core temperature between 55°C and 95°C. During input of the profile program, final F-values of 0—9999 can be input as setpoint. The display must first be switched over to “F”.

The F-value is also calculated in the background during standard cooking.
In automatic operation the current F-value can be called up by pressing the Fkey.
After the end of the profile the final F-value reached can be called up
by pressing the F key.
Calculation of the F-value starts as soon as the core temperature has exceeded 55°C.
31
5 Features
5.1.7 C-value cooking
The calculation of the C-value (reduction in cooking damage) is based on the
time during which a temperature acts on the product and is derived from a
table for C 38°C cooking.
100°C
The subscript value 100°C is the reference temperature. At a chamber temperature of 100°C and an action time of 1 min a C-value of 1 is reached.
The superscript value 38°C is the z-value (= time-temperature relationship of
the bactericidal factor) and means that every temperature increase of 38°C
increases the C-value 10fold.
The C-value is calculated for a product ambient temperature (= chamber temperature) between 55°C and 100°C. During input of the profile program, final
C-values of 0—9999 can be input as setpoint. The display must first be switched over to “C”.

5 Features
5.1.8 Humidifying by pulse-pause control
The relative humidity in the chamber can be controlled automatically, or alternatively can be set through an adjustable pulse-pause ratio.
The selection is made by switching over with the key % or P when the
profile program is being input. Switch-over is also possible while the process
is running. The pause time in seconds is input directly on switching over, separately for each segment. The pulse time is input as a fixed value through the
coding function (Cd 03).

5.1.9 Extra temperature
The transducer for additional tasks, such as monitoring or controlling a smoke
generator or for controlling an afterburner, can be connected to input 4.
Pressing the key Z switches the display of actual values and setpoints from
chamber temperature to the extra temperature.
Configuration and programming are the same as for the chamber temperature;
alternatively a fixed value can be set through the coding function (Cd 45 and
Cd 46).
v Section 6.1.6. “Controller configuration”
5.1.10 Repeat cycles
Repeat cycles for certain segments can be input during the input of the profile
program. If the segments 2 to 5 have to be repeated twice in the profile, the
start segment for the repeat (segment 2) is input under segment 5, together
with the number of repeats (2x).
As a result the profile runs a total of 3 times through segments 2 to 5.

Action on supply interruption
There are several possibilities for the action after interruption of the supply during automatic operation; they can be set at the configuration level.
v Section 6.1.1. “General instrument data”
Continue
The instrument automatically continues the profile program at the point where
it was interrupted.
Profile abort
The instrument aborts automatic operation and returns to the basic status.
Stop
After the supply has been restored the profile program stops at the point where it was interrupted. The LED in key A is flashing.
h Abort automatic operation with A, or
h continue automatic operation with E
Continue
at xx%
The value of the difference xx can be adjusted at the configuration level.
If, following a supply failure, the difference of the chamber temperature before
and after the supply failure is less than or equal to the value xx%, the profile
program continues automatically.
If the difference is larger, the instrument acts for “stop”, i.e. there is a manual
decision on profile program abort or continuation.
h Abort automatic operation with A, or
h continue automatic operation with E
5.3
Real-time clock (LPF-200)
The profile controller LPF-200 incorporates a real-time clock. In the basic
status it indicates the clock time (hours:minutes). It can be used to start the
profile program at a certain point of time (day, moth, year, clock time). If the
controller is disconnected from the supply, the clock continues to operate, typically for 8 days.

Explanation
Starting self-optimisation
H
The controller must be in manual operation with
setpoints appropriate to practical conditions.
For each controller the display shows 0 0 0
(top display is flashing).
One of the controllers has to be selected for self-optimisation.
h Select controller
h Input 001 for the required controller
h Enter with E
Self-optimisation starts immediately after entering.
If a controller is configured with a special function, such as
psychrometric humidity, ratio or difference, self-optimisation of
this controller must not run at the same time as that of other
controllers.
Recommendation: optimise first the chamber temperature, let
it stabilise at a reasonable value, and then optimise the humidity controller.
The profile program number display shows “t”.

6.1.9 Limit comparators
6 limit comparators can be used for comparison between all analogue process
parameters inside the controller, and for monitoring against a set limit. Either a
process value or a setpoint can be selected for the first value in the comparison; only a setpoint can be selected for the second value (Cd 70, 71). The
particular function is selected only with Cd 72. Relays are automatically assigned as outputs to the selected limit comparators.
v Section 4.2 “Arrangement of the relay outputs”
H
The limit comparator is switched off if 000 is input for the first
value in the comparison (Cd 70).
Comparator
(2 analogue
values)
The difference between 2 analogue values can be used e.g. to realise an advance or follow-on contact. The relay pulls in when the difference between the
first and second value in the comparison exceeds the lower limit (Cd 73).
Settings of the upper limit are not permitted at this function.

The switching action of the relay is reversed.

Replacement
value
In case of overrange or underrange through a pobe break the limit comparator
can no longer operate correctly.
The controller then uses a so-called replacement value (Cd 76) which defines
the switching action of the limit comparator to ON or OFF.
Limit
comparator
inactive time
The inactive time (Cd 77) is a time interval during which the old status of a limit
comparator is retained unchanged.
In case of a sudden change in setpoint the difference between setpoint and
process value is very large initially so that a limit comparator would immediately respond. If this is undesirable, the limit comparator can be set inactive for a
period of time until the process value approaches the setpoint (Cd 78).
Delta value
for inactive
time
This value sets the amount of the difference above which a setpoint step
makes the limit comparator inactive.

8 Self-optimisation
General note
The self-optimisation function (SO) is purely a software function and is incorporated in the controller. SO employs a special procedure to analyse the response of the control loop to steps in control output.
Using the control loop response (process value) an extensive computing algorithm determines the controller parameters for a PID controller and stores
them. If a double-setpoint controller has to be optimised, the algorithm determines two separate proportional bands (Xp1 and Xp2). In case of a switching
double-setpoint controller the switching cycle time Cy2 is also calculated.
The SO procedure can be repeated as often as desired.
H
Process value
far away from
setpoint
79
v SO can be activated through Cd 08 aktiviert. With cascade control,
the controller of the inner control loop has to be optimised first.
(v Section 6.1.1. “General instrument data”)
SO operates according to two different procedures which are selected automatically depending on the dynamic state of the process value and its distance from the setpoint at the start of SO. SO can be performed starting from
any dynamic course of the process value. If process value and setpoint are far
apart when SO is activated, a switching line is determined and the controlled
variable is made to perform a forced oscillation about this line during the selfoptimisation procedure.
8 Self-optimisation
Process value
close to
setpoint
If there is only a small deviation between setpoint and process value, e.g.
when the control loop has stabilised, a forced oscillation is produced about
the setpoint. Using the recorded process loop data of the forced oscillation,
the calculation determines the controller parameters Tn, Tv, Xp1, Xp2, Cy1,
Cy2 and also the optimum filter time constant for this control loop for filtering
the process value.
SO is then successfully concluded.
H
If after stabilisation a switching controller exhibits permanent process
value oscillations in synchronism with the switching action, it is recommended to reduce Cy further.
