HOW TO DISMANTLE SYSTEM 2200
Picture 1:
The back panel of the module is
detached from the housing by way
of a screwdriver.
Picture 2:
After this, the back panel can be
pulled out together with the PCB,
but please notice the position of
the PCB as there is a number of
different positions in the house. Do
not pull the wires unnecessarily,
instead pull the PCB.
Switches and jumpers can now be
moved.
When assembling the back plate
and housing, please make sure no
wires are stuck.

hereby declares that the following product:
Type: 2289
Name: Signal calculator
is in conformity with the following directives and standards:
The EMC Directive 2004/108/EC and later amendments
EN 61326-1
For specification of the acceptable EMC performance level, refer to the
electrical specifications for the module.

PEAK-HOLD:
At a deactivated digital input the output value is the greatest input value
registered since the last reset. Activation of the digital input will set the output
value at the present input value (reset).
DELAY:
The delay function transfers the input value to the output according to an
exponential curve (R/C delay), where the time constant of the R/C delay can be
entered.
PID CONTROLLER:
Features the following regulation parameters: XP (proportional band), TI
(integrating time), and TD (differentiating time). The units are selected as XP %,
TI s, and TD s. By selecting TI and TD as 0, the function will be a pure proportional
controller. The regulation can be either direct or inverted. The setpoint can be
selected as an internal or external current / voltage signal.
MANUAL / AUTOMATIC CONTROLLER:
The digital input is used to change between the manual and automatic mode. In
the automatic mode the analogue output follows input A. When changing to the
manual mode the analogue output is fixed and can now be activated up or down
manually. The output holds the manual setting for an unlimited period.
SIGNAL LIMITER:
By the signal limiting function the output follows the input values linearly in the range
between the min. and max. settings. At input signals outside the min. and max.
settings, the output is fixed on either the min. or the max. value. The min. or the
max. value can be set externally by means of the other analogue input.
AVERAGING TRANSMITTER:
The averaging function calculates an accurate average value of the input values
over a set period. Once this period has expired the output will be updated by the
average value. This means that the ouput will typically make a jump at each update.
A stack function can be selected to increase the updates of the output and to
decrease any jumps while still keeping the set averaging period.
SLOPE TRANSMITTER (DI/DT FUNCTION):
The dI/dt function converts the slope of the input over a set period to an analogue
output signal. The min. and max. slope to be converted are entered in % of the
input span. The slope can be selected as either positive or negative. By means
of a pressure transmitter the dI/dt function is suitable for for instance leak
monitoring or flow measurement of substances with a high viscosity grade.

SIGNAL CALCULATOR 2289
• Two analogue inputs
• Multiple functions
• Front-programmable
• 3-digit LED display
• Version with a Pt100 input
• Analogue output
APPLICATION:
Operates as a PID controller with an analogue or a Pt100 input, a manual /
automatic controller, an analogue calculator with a scale function on both inputs,
a sample-hold transmitter, a peak-hold transmitter, a delay transmitter, a signal
limiter, averaging of noisy signals, monitoring of a signal’s slope, or an analogue
multiplexer. •The 2289 Signal Calculator will meet the demands of any process
engineer with an unexpected or special signal processing assignment at hand.
TECHNICAL CHARACTERISTICS:
The unit is built around a microprocessor core with an efficient program operation.
The basic calibration data and the present set-up are saved in an EEPROM
thereby avoiding the loss or change of data at power off. The user interface
consists of a 3-digit display and 3 front function keys. The input and output values,
function, and all parameter selections are entered by means of the user interface.
Both the input signals and the output signal can be inverted.
FUNCTIONS:
ANALOGUE CALCULATOR:
Contains the following calculation functions: addition, subtraction, maximum /
minimum selection, multiplication, division, raising to a power and root extraction.
At raising to a power and root extraction, any of the analogue inputs can be
selected. By means of the scale function the calculation functions can be
executed on differently scaled input signals.
SAMPLE-HOLD:
Activation of the digital input (hold) will set the output value to the present
input value and will hold this value for as long as the digital input is active. At a
deactivated digital input the output value will track the input value.

5.0 APP - Selection of application.
5.1 FUn - Selection of function.
Possible selections are:
001 = Addition of 2 analogue signals (P1*A + P2*B + P3).
002 = Subtraction of 2 analogue signals (P1*A - P2*B + P3) or
(P2*B - P1*A+P3).
003 = Max. selection of 2 analogue signals Max. (P1*A, P2*B) + P3.
004 = Min. selection of 2 analogue signals Min. (P1*A, P2*B) + P3.
005 = Multiplication of 2 analogue signals (P1*A*B) + P3.
006 = Division of 2 analogue signals (P1*A/B) + P3 or (P1*B/A) + P3.
007 = Root extraction / Raising to a power (P1(A or B)P2) + P3.
A and B are the input signal spans for the A and B inputs respectively.
P1 and P2 are the scale factors multiplied on the A and B inputs
respectively. When the scale factors are 1, the input signal is scaled
to its full value. A scale factor of 0.5 will scale the input signal to half
its value. At the multiplication, division, root extraction and power
functions the scale factor must be set as P1. At the root extraction and
raising to a power P2 is the exponent. An exponent of 0.5 will result
in a square root function; an exponent of 2 will raise the input to the
second power.
P3 is a calculation offset set to values between 0 and 1 (0...100%)
and added to the present signal range of the output. If for instance the
output is set to a signal range of 10...20 mA, a P3 of 0.5 will result in
an extra offset of 50% of the output span. This means that the signal
range starts at 15 mA and starts to limit at 20 mA. At most calculations,
the calculation offset must be set to 0, but at complex calculations it
can be used for moving the range of the output signal range.

VDC, the jumper on the PCB must be moved.
Possible selections are:
001 = current output in the range 0...10 mA

obtained. Therefore it is important that the the proportional band Xp,
the integrating time Ti, and the differentiating time Td are adjusted
according to the present application. Before setting the parameter,
the method of regulation direct / inverted must be determined. Direct
controlling results in an increasing output when the process value is >
the setpoint. Inverted controlling results in a decreasing output when
the process value is > the setpoint. Less experienced users may use
the following rule-of-thumb for determining the process parameters:
1. Set Xp at max., Ti and Td at 0 (only proportional controlling).
2. Reduce Xp until the process starts oscillating.
3. Double Xp.
4. Set Ti at max.
5. Reduce Ti until the process starts reoscillating.
6. Double Ti.
7. If the controller is too slow reaching its setpoint, the differential
controller can be activated. The differential function increases the
control signal proportionally to the rise time of the process signal.
Therefore the setting varies according to the process.
012 = Manual / Automatic controller:
The digital input is used to switch between the manual and automatic
mode. A deactivated digital input results in the auto function, where
the value of input A is transferred to the output. An activated digital
input results in the manual function, where the output adopts the value
of input A when activated. Now the output can be activated up or
down manually. The output holds the manual setting for an unlimited
period. The setting is saved at power failure.
013 = Signal limiter:
The output follows the value of the selected analogue input (A or B)
linearly in the range between the min. and max. settings. At input
signals smaller than the min. or greater than the max. settings, the
output is held on the min. or max. value respectively. The min. or max.
value can be set externally via the other analogue input.
014 = Averaging function:
The averaging function reads the input value of the selected A or B
channel every 20 ms and adds up the measurements in a memory.
When the averaging time has expired, the average value is calculated
by dividing the memory value by the number of measurements made,
and the output is then updated by this value. The averaging function
61
When calculating scale factors the input and output signal spans
always have values between 0 and 1. When adding 2 identically scaled
input signals of for instance 4...20 mA, the output would be 8...40 mA
at the same scaling. But as the output follows standard current signals
of 0/4...20 mA, the scaling on the output is double of the scaling on
the inputs. This means that each input must be scaled by only half
the scale of the output. The figures can be calulated according to the
following expression (P1*A + P2*B + P3) = 1, and with this in mind it
will be (0.5*1+0.5*1 + 0) = 1.
When adding 2 differently scaled input signals, the scale factors can
be calculated as follows:
Signal A is 4...20 mA corresponding to a flow of 0...100 m3 / h
Signal B is 4...20 mA corresponding to a flow of 0...150 m3 / h
The output signal of 4...20 mA must correspond to a flow of 0...250 m3 / h
Signal A must be scaled by 100/250 corresponding to a scale factor
P1 of 0.4.
Signal B must be scaled by 150/250 corresponding to a scale factor
P2 of 0.6.
008 = Sample-Hold:
When the digital input is deactivated, the analogue output follows the
selected analogue input (A or B). When the digital input is activated,
the output value is fixed at the value it had when activated until the
digital input is deactivated. The hold value is saved at power failure.
009 = Peak-Hold:
When the digital input is deactivated, the greatest value (the peak
value) of the selected analogue input (A or B) since the latest reset is
held. An activated digital input will reset the peak value to the value
that the input had when activated. By inverting the input and output
signals, the smallest input value is held. The peak value is saved at
power failure.
010 = Time delay:
The output follows the values of the selected input (A or B) averaged
according to an exponential function.
011 = PID controller:
In a correctly tuned PID controller, the constant error will be eliminated.
This means that at a correctly tuned Xp, Ti, and Td, a regulation
accuracy close to what the process value can be measured to can be

has 2 parameter settings, AtI - averaging time, and StS - number
of memories. The averaging time is the time that is averaged. The
number of memories to be selected is (1...14). The time between the
updates of the output is determined by the average time divided by
number of memories (AtI/StS). If AtI/StS is smaller than 20 ms, the
output will be updated every 20 ms.
Example:
With an average time of 10 s and 1 memory, the period between the
updates of the output will be (10/1) = 10 s. The output will typically
make a jump at the update.
If the number of memories is for instance 10, the period between the
updates of the output will be (10/10) = 1 s. Each memory (1…10) will
hold the average value for 1 s. The output is updated every second
by the average value of the 10 memories. This means that the jumps
on the output will be smaller. The 10 memories will be replaced
continously according to the FIFO method (first in, first out).
015 = Slope transmitter (dI / dt function):
The slope transmitter converts the slope (dI) of input A according to a
set period (dt) to an analogue output signal. Each time the set period
(dt) has expired, the input value is read. The latest readout is compared
to the previous, and the difference between these two values is the
slope of the input signal, which is converted to an analogue output
signal. The output is updated each time a period (dt) has expired. The
slope can be selected as either positive or negative. The input signal
can be averaged according to an exponential function so that it can be
applied to noisy signals.
Example:
Minimum slope (dIL) = 0%.
Maximum slope (dIH) = -1%.
Period = 5 seconds.
Analogue output = 4...20 mA.
Result:
Has the input value not been changed within 5 seconds, the output
will be 4 mA. Has the input value decreased by 0.5% after 5 seconds,
the output will be 12 mA. Has the input value decreased by 1% after 5
seconds, the output will be 20 mA.
016 = Analogue multiplexer:
Expression: (P1*A) and (P2*B).
The input (A or B) to be transferred to the output is selected by the
digital input. Input A has been selected when the digital input is
deactivated, and input B has been selected when the digital input
is activated. P1 and P2 are scale factors multiplied on input A or B
respectively. When the scale factor is 1, the input value is scaled to
its full value. A scale factor of 0.5 will scale the input signal to half its
value.
