SYSTEM DESCRIPTION
Function description
T ype 1150 is a process and progr am controller with up to four controller or program channels. The instrument is built to the format 144 mm x 130 mm for a standard 92 mm x 92 mm panel cut-out and a mounting depth of 170 mm.
The display is a 5" color screen with 27 colors. The lay out of the screen templates can be individually adapted and adjusted. Two freely configurable screen templates make it possible to customiz e the placing of texts, process values, background pictures and icons.
A maximum of 4 analog inputs and 6 logic inputs are available, as well as six expansion slots for switched or analog outputs.
A setup program is available for direct configuration via a PC. Linearizations for the usual transmitter outputs are stored within the instrument, four customer-specific linearization tables can be programmed.
A math and logic module can be used to adapt the instrument to a very wide range of control tasks. A serial interface RS422/485 or Profibus-DP can be used to integrate the instrument into a data network. Modules can be retrofitted quite simply by the user. The electrical connection is made at the back of the instrument, via plug-in screw terminals.

INSTALLATION, COMMISSIONING AND MAINTENANCE
General notes
ATTENTION!
This device should only be installed or repaired by qualified personel using the correct tools!
Always disconnect the power this device before servicing or changing signal connections!
Failure or interf erence may result from contamination, short circuit, voltage interruption or faulty/missing wiring termination.
Check for loose or improper electrical connections or under voltage if unit does not power up.
Location and climatic conditions
The conditions at the location must meet the requirements specified in the technical data.
The ambient temperature at the location should be - 5 to + 50 °C with a relative humidity below 75%
Close mounting
Minimum spacing of panel cut-outs horizontal min. 54 mm vertical min. 54 mm
Assembly
From the bac k, fit the seal that is supplied onto the instrument. Insert the instrument from the front into the panel cut-out.
18 - 1150
From behind the panel, slide the mounting brac kets into the guides on the sides of the housing. The flat faces of the mounting brackets must lie against the housing.

Installation
INSTALLATION, COMMISSIONING AND MAINTENANCE
ATTENTION!
The choice of cable - the installation and the electrical connection must conform to the requirements of VDE 0100 “Regulations on the Installation of P ower Circuits with Nominal V oltages below 1000 V” or the appropriate local regulations.
The electrical connection may only be carried out by properly qualified personnel.
The instrument must be disconnected/isolated electrically incase of accidental contact with live parts.
A current-limiting resistor interrupts the supply circuit in the event of a short-circuit. Ho we v er , the load must be fused for the maximum relay current to prevent the contacts of the output relay from becoming welded in the event of a short-circuit.
Electromagnetic compatibility conforms to the standards and regulations cited in the technical data (see Chapter Technical data).
Run input, output and supply cables separately and not parallel to one another .
All input and output signal cables must be shielded twisted pairs to prevent crosstalk, electrical noise and interferences.
The shield of all transmission lines must be connected on the instrument side to potential earth.
The PE terminal on the instrument must be connected to earth ground. This cab le must ha ve at least the same conductor cross-section as used for the supply cables. Grounding and earthing leads must be wired in a star configuration to a common earth point that is connected to the protective earth of the electrical supply . Do not loop earth or ground connections, i.e . do not run them from one instrument to another.
Please observe the relevant safety regulations and electrical installation codes for your area.
Do not connect any additional loads to the supply terminals of the instrument.
The instrument is not suitable for use in areas with an explosion hazard (Ex areas).
In addition to faulty installation, incorrect programming/configuration of the controller (setpoint, data of the parameter and configuration levels, internal alterations) can also interfere with the correct operation of dependent processes, or even cause damage. Safety devices should always be provided that are independent of the controller (such as overpressure valves or temperature monitors/limiters) and only capable of adjustment by authorized personnel.
Since adaptation (self-optimization) cannot be expected to handle all possible control loops, an unstable process parameterization is theoretically possible. The stability of the actual value derived from the self­tune should therefore be checked.
The measurement inputs of the controller must not exceed a maximum potential of 30 V A C or 50 V DC against PE.

Operating „program controller/generator“
If the instrument is configured as a program controller/generator, progr ams hav e to be created first, by using the internal program editor or the setup program.
Program editor
General
50 programs with up to 99 segments can be programmed; a total of 1000 segments can be implemented. Programs are created by programming setpoints and segment times, segment by segment. Furthermore, the states of the control contacts 1 — 8 and the active parameter set can be defined for
each segment. The setpoint profiles can be output either as a ramp or a step (configurable). Output as a ramp has been chosen for the following diagrams.
Tolerance band
To monitor the process value, a tolerance band can be applied around the setpoint profile f or each segment.
If the upper or lower limit is infringed, a tolerance band signal is generated, which is internally processed or produced via an output.

CONFIGURATION
Parameters and functions at the configuration level
General
The following applies to the representation of parameters and functions at the configuration level: The parameter is not displayed or cannot be selected if
the instrument features do not permit the function assigned to the parameter . Example:
Output 3 cannot be configured if no output 3 is available in the instrument.
the parameter is irrelevant to the function that has been configured. Example:
Analog input 1 is configured to “Pt100”, which means that displa y start and end for standard signals cannot be selected.
NOTE
Some parameters are only available for a fixed-setpoint controller (with or without ramp function) or a program controller/generator . For fixedsetpoint controllers , these parameters and settings are marked by a superscript “F” (e.g. rampF), for program controllers /generators by a “P”.

(See below for explanation)
NOTE
As opposed to all the other settings, entry of the start and end value is linked to the latest measurement at the input concerned.
As a rule, these values cannot be adopted by another instrument.
Customized recalibration
A signal is processed electronically (conversion, linearization …) to produce a measured value via the analog inputs of the controller. This measured v alue enters into the computations of the controller and can be visualized on the displays (measured value = displayed value).
This fixed relationship can be modified if required, i.e. the position and the slope of the measurement characteristic can be altered.
Procedure
Apply two measurement points ((1), (3)), one after another , to the controller; they should be as f ar apart as possible.
At these measurement points, enter the required display v alue (start value, end value) in the controller. A reference instrument is most convenient for determining the measured values M1 and M2.
Measurement conditions must remain stable during programming.

NOTE
If recalibration is carried out without a reference instrument, the offset must be taken into account when moving to measurement point (3).
To cancel recalibration, the start and end values have to be prog rammed to the same v alue. This automatically sets the start value to 0 and the end value to 1.
Any subsequent recalibration will otherwise be based on the corrected characteristic.

Functions are assigned here to the logic signals of the logic inputs, limit comparators and logic functions (formula).
In addition, the functions for control contacts, tolerance band signal and program end signal are defined for program controllers/generators.
In the case of the fixed-setpoint controller , the ramp end signals can ha v e functions assigned.
The functions are arranged in two groups:
Edge-triggered functions
The logic function reacts to switch-on edges. The following functions are edge-triggered:

Combined logic functions
The functions are implemented through the combination of up to four control variables.
Any control variable can be selected. The states Z1 to Z4 are assigned to the control variables in descending order of the control variables (see list on the right).
Example: The process value is to be selected via a logic
input and the state of one limit comparator. This results in the following assignment:
Z1 - logic input 1 Z2 - limit comparator 1
Setpoint/process value switching
Setpoint Process value Z2 Z1

1 = contact closed / ON
NOTE
If switching between two setpoints or two process values is required, only one logic function has to be configured.
If more than two logic functions are configured to setpoint switching or process value switching, only the first two (see list “Control variable - State”) are significant.

C-level control is used for the control of carbon in the atmosphere of a gas coking furnace. The C-level is determined through the o xygen measurement with a zircon dioxide sensor and measurement of the sensor temperature.
C-level control is an extra.
C-level calculation
The calculations of the controller are based on the following:
E = 0.0992 T { -lg (PCO) + 1.995 + 0,15 Cp + lg(Cp) } mVK + 816.1 mV
E - e.m.f. of the zircon dioxide sensor T - sensor temperature in K Pco- partial pressure CO in percentage of volume Cp- carbon level
Sequence control
Operation using a zircon dioxide sensor is subject to a fix ed time schedule . The sensor has to be “flushed” at regular intervals (cycle time) to ensure faultfree measurement.
During flushing and the subsequent recovery time, the controller is in manual mode. The latest measurement is stored. The a v erage value of the most recent outputs is produced.
During flushing, the output variable logic 1 is “1” The flushing procedure can be controlled b y linking it to an output.

Self-optimization
Oscillation method
Self-optimization SO establishes the optimum controller parameters for PID or PI controllers. Depending on the controller type, the following controller parameters can be defined: Reset time (Tn), derivative time (Tv), proportional band (Xp), cycle time (Cy), filter time constant (dF) The controller selects one of two procedures (a or b), depending on the size of the control deviation:
a) SO in start-up phase b) SO at setpoint
Start of SO Start of SO
Switching line
Step response method
This type of optimization involves determining the control parameters through an output step that is applied to the process. First a steady output is produced until the process value is “steady” (constant). Afterwards, an output step (step size - user defined), which can be defined by the user, is automatically applied to the process. The resulting response of the process v alue is used to calculate the control parameters.
Self-optimization establishes the optimum control parameters for PID or PI controllers, in accordance with the selected control structure.
Depending on the controller type, the following control parameters can be defined: Reset time (Tn), derivative time (Tv), proportional band (Xp), cycle time (Cy), filter time constant (dF) Optimization can be started from any system status and can be repeated as often as is required. The controller outputs (analog, relay, solid-state), the steady output and the step size (min. 10%) have to
be defined.
Principal applications of the step response method
Optimization instantly after “power on”, during the start-up phase considerable time savings, setting: steady output = 0 %.
The process does not readily permit oscillations (e.g. highly insulated furnaces with small losses, long oscillation period)
Process value must not exceed setpoint. If the output (with stabilized setpoint) is known, an overshoot can be avoided through the following adjustment: steady output + step size <= output in stabilized condition

OPTIMIZATION
NOTE
With output type “solid-state”, the cycle time during optimization is reduced to 8 x the sampling time.
With the “relay” output type, care has to be taken that the process value is not influenced by the switching cycle time, otherwise optimization cannot be completed successfully.
Solution: Reduce the cycle time Cy, until the process value is no longer influenced. (Manual mode can be used for the adjustment!)

Check of the optimization
The optimum adaptation of the controller to the process can be checked b y recording the start-up phase with the control loop closed. The diagr ams below indicate possible adjustment errors and how these can be corrected.
The control response of a third-order control loop of a PID controller is shown as an example. Howe ver , the procedure for adjusting the controller parameters can also be applied to other control loops.
