1. APPLICATION
The RE23 controller is destined to a programming control of temperature
and other physical quantities e.g. pressure, humidity, level, flow.
The measured value, the set value parameters of the realized program
or the output signal are displayed on two displays. The measuring input
is universal for RTD, TC or for linear standard signals. The controller
has one output enabling the heating or cooling type control. The manual
control is also possible.

3. PREPARING THE CONTROLLER TO WORK
3.1. Safety
The RE23 controller fulfils requirements related to the safety of electrical measuring instruments for automatics acc. to the EN 61010-1 standard, requirements related to the resistance against electromagnetic
interference acc. to the EN 61000-6-2 standard, and electromagnetic
interference emission occurring in industrial environment acc. to the
EN 61000-6-4 standard.
3.2. Installing the controller in the panel
Fix the controller in the panel by means of two screw holders acc. to
the fig.1.
The hole in the panel should have 45+0,6 x 45+0,6 mm dimensions.
The tickness of the material for panel execution cannot exceed 15 mm.

When connecting the supply, one must remember that an automatic
cut-off or a switch should be installed near the device, easily accessible
for the operator and suitably marked.
3.4. INSTALLATION RECOMMENDATIONS
The RE23 controller fulfils requirements concerning the fastness against
electromagnetic interference occurring in the industrial environment acc.
to obligatory standards.
In order to obtain a full immunity of the controller against electromagnetic interference in an unknown environment interference
level it is recommended to observe following principles:
- do not supply the controller from the network near devices generating
high impulse interference and do not use common earthing circuits
with them.
- apply network filters,
- apply metallic shields in the shape of tubes or braided screens to
conduct supplying wires,
- wires supplying the measuring signal should be twisted in pairs, and
for resistance thermometers in a 3-wire connection, twisted from wires
of the same length, cross-section and resistance, and led in a shield as above,
- all screens should be one side earthed, and led the nearest possible
to the controller, - apply the general principle that wires leading different signals should
be led the farthest possible between them (not less than 30 cm), and
their crossing executed at a right angle.
4. STARTING TO WORK
After the correct installation and connecting to the power, the controller
carries out the display test, displays the controller type on the upper
display and the program version on the lower display.
Next, the measured value is displayed on the upper display or a message informing about abnormalities (table 6), and the set point of the
controlled quantity on the lower display.
The index 1 informs about the controller output state:
■ when lighting - output is switched on,
■ when blanking - output is switched off
The index P informs about the programmed working mode of the controller:
■ when lighting, that the control is switched on acc. the program,
■ when flickering, that means the control has been disabled by the operator, but the program is not finished,
■ when blanking, that means the control is disabled because of the program.
Termination or the controller has been programmed in the constant valued control mode.
The index
informs about the manual working mode of the control:
■ when lighting - the manual control is switched on,
■ when blanking - the automatic control is switched on

5.2. Configuration parameters
The description of the configuration parameters is included in the table
1. The return to the normal working mode follows after the simultaneous
pressure of
and
push-buttons or automatically after 30
sec. since the last push-button pressure. Some parameters can be invisible - that depends on the current controller configuration.
The access to configuration parameters can be secured by a password.
If the security code is set (seCU parameter is higher than zero), one
must give it. During its setting, the codeinscription is displayed in the
lower display. If the value is not given or is erroneous, the read only
inscription appears on he displays and the user will only be able to
review parameter values. The introduction of the security code is shown
on the fig. 7. The programmer menu has its own seCpcode. Principles
of its operation are identical as for theseCU code.

5.3. Change of settings
The change of the parameter setting begins after pressing the
push-button. One can carry out the setting choice by means of
and
push-buttons, and accept it by the
push-button.
The cancellation of change follows after the simultaneous pressure
of
and
push-buttons or automatically after 30 seconds
since the last push-button pressure.
The way to change the setting is shown in the fig.10.

5.5. Controller programming
in the programmed working mode
The controller controls the object acc. to the set point changing in time in
accordance with the assigned function, named the program.
The program is composed maximally of 9 segments. For each segment,
one must give the duration time and the 4 set point on the segment
end. The segment time and the set point equals 0 mean the end of the
program.
Moreover, one must define:
• the number of cycles, that is how many times the cycle is to be repeated,
• the way of the program beginning: from the measured value or from
the value defined in the next parameter,
• the set point on the program beginning,
• the controller behaviour after the program termination: switch the output off or continue acc. to the last set point.

After defining the set point program, one must start the control from the
beginning, pressing simultaneously
and
push-buttons.
The lighting index P means that the control is realized acc. to the set
point calculated from the program.
The program will start acc. to the Strt parameter setting:
■ the value sp0 means, that the initial set point value is the setting of the sp0 parameter,
■ the pU0 value means, that the initial set point value is the value measured in the moment of the program start.
The realized program can be stopped by pressing simultaneously
and
push-buttons. The flickering index P means, that
the control is stopped (the control output is disabled). The continuation
of the stopped program follows after the renewed pressing of
and
push-buttons. The stopped program can be started from
the beginning by pressing simultaneously
and
push-
buttons.
Parameters of the realized program can be displayed on the lower display by pressing the
push-button.
Instead of the current set point, following parameters are displayed:
■ n - number of the currently performed segment,
■ t - time which elapses since the beginning of the actually performed segment [in minutes]. For times higher than 999 minutes, the oldest digit is displayed alternately with the symbol t
■ l - number of program cycles which still remains to perform. The number 0 means the program termination.
After the program termination, the controller carries on in accordance
with the End parameter setting:
■ the off value means, that the control is ended, the control output is disabled, the P index is blank. On the lower display instead of the segment number the message End is displayed. The controller
waits for a renewed program start since the beginning, by
and
push-buttons.
24
■ the cont value means, that the control is continued acc. to the last
set point in the program without the time count down. The P index is still lighting, the number of cycles to do is equal 0. On the lower display instead of the segment number, the message
cont is displayed. The control can be disabled by a simultaneous pressure of and
, push-buttons, or restart the program from the beginning by
and
push-buttons.
6. INPUT AND OUTPUT OF THE CONTROLLER
6.1. measuring input
The controller has one measuring input, which one can connect different
types of sensors or standard signals to.
The choice of the input signal is carried out by the inpt parameter.
For different types of inputs, depending on the option code, one must
give additional parameters.
For the Pt100 resistance thermometer, one must choose the kind of
connection. In a three-wire connection, the line resistance compensation goes on
automatically.
In a two-wire connection, one can give additionally the line resistance.
For thermocouples, one must give the way of temperature compensation of cold ends - automatic or manual, and at manual compensation
- the temperature of cold ends.
For linear inputs, one must give the indication for the lower and upper
threshold of the analog input.
The additional parameter is the number of digits after the decimal point,
the rEso parameter. For temperature sensors, it defines whether the
measured temperature and the set point temperature is to be shown
with a place after the decimal point.
For linear inputs, it defines the resolution which the measured value and
values of some parameters are shown with.
The correction of the measured value indications is carried out by the
shif parameter.
25
6.2. OUTPUT
The controller has one output, which it is possible to choose the onoff or PID control in. For the PIDl control, one must additionally set
the pulse repetition period.The pulse repetition period is the time which
expires between successive switches of the output during the proportional control.
The length of the pulse repetition period must be chosen depending on
dynamic properties of the object and suitably to the output device
For quick-acting processes, it is recommended to apply SSR relays.
The relay output is used to control contactors in slow-acting processes.
The use of a high pulse repetition period to control quick-acting processes
can give unwanted effects in the shape of oscillations.
Theoretically, the smaller the pulse repetition period, the better the
control, but for the relay output, it should be as high as possible in order
to extend the relay life.

7. CONTROL ALGORYTHMS
7.1. ON-OFF CONTROL
To select the ON-OFF control, one must set the parameter pb=0. Next,
set the hysteresis value - Hy. The action of the output on heating (fig.12)
is set by the parameter out=inu, and on cooling, by the parameter
out=dir.
Fig.12. Operation way of the heating type output.
7.2. PID CONTROL
The choice of PID control algorithm or also PI, PD or P control algorythm consists on a suitable setting of parameter values - proportional
band (pb), integrating element (ti) and differentiating element (td).
The switching of the giving element off, consists on setting the parameter on zero. The operation way of the heating type output is chosen by
setting the parameter out1=inu, and the cooling type by setting the
parameter out=dir. The successive parameter to set is the pulse
repetition period of the output (to).
27
8. ADDITIONAL FUNCTIONS
8.1. DISPLAY OF THE CONTROL SIGNAL
After pressing the
push-button, the value of the control signal
(0...100%) appears on the display. On the first digit, the mark h is
displayed. The return to the normal operation follows after the double
push-button.
pressure of the
8.2. MANUAL CONTROL
The manual control gives the possibility, among other things, to identify
and test the object or control it after the sensor damage.
The entry into the manual control mode follows after holding down the push-button when displaying the control signal. The manual
control is signaled by the pulsation of the measured value.
The controller breaks the automatic control and begins the manual
control of the output.
The value of the control signal is displayed on the lower display, preceded
by the symbol h.
and
push-buttons serve to change the control signal.
The exit to the normal working mode follows after the simultaneous
pressure of
and
push-buttons.
After setting the ON-OFF control on the output (parameter pb = 0), one
can set the control signal on 0% or 100% of power, however when the
Pb parameter is greater than zero, the control signal can be set on any
value from the 0...100% range.
28
8.3. controller behaviour after
the sensor damage
It is possible to configure the output state after the sensor damage:
­­■ at output configuration for proportional control (pb>0) the control signal value is defined by the oIflparameter,
­­ at output configuration for the ON-OFF control (pb=0), the output
■
will be disabled, at output operation as heating, or enabled - at output operation as cooling.
8.4. Manufacturer’s settings
One can restore manufacturer’s settings, during the supply switching
on, holding
and
push-buttons till the moment when the
inscription fabr appears in the upper display.
29
9. selection of PID parameter settings
9.1. Automatic choice of settings
The controller has the function of the automatic PID setting selection.
These settings ensure in the most of cases the optimal control.
To begin the autotuning, one must transit to the tune position (acc. to
the fig.7) and hold the
push buton during at least 2 sec. If the
proportional band is equal zero or the aTfn parameter is set on off
or the tsp parameter is set on pr9 then it will not be possible to begin
the autotuning.
The flickering upper display informs about the activity of the autotuning
function. The autotuning duration depends on the dynamic properties of
the object and can last maximally 10 hours. During the autoadaptation
or directly after it, overshoots can appear and for this reason, one must
set a lower set point, if it is possible. After the autotuning termination,
calculated PID settings are stored in the non-volatile memory and the
process control with new settings begins.
The autotuning process may not begin or be broken without the calculation of PID settings, if:
– the control deviation is lower than 6.5 % of the range (splH-spll)
– the time of the object preliminary stabilization or the admissible autotuning duration will be exceeded,
– a decay of the controller supply occurs,
– the
push-button has been pressed,
– calculated parameter values are beyond the range.
In such cases the control with previous PID settings will begin.
30

to a unitary jump.
9.2. manual selection of settings
Set the on-off control with a minimal hysteresis. Set the set point as to
we can observe the run of the measured value as in the fig.13.
One must read out the delay time To and the maximal temperature
accretion rate from the object characteristic presenting the controlled
value in the function of time, from the dependence:
Vmax =
∆PV max
∆t
Calculate PID settings acc. to following formulas:
Pb = 1.1 • Vmax • T0
- proportional band
ti = 2.4 • T0
- integration time constant
td = 0.4 • T0
- differentiation time constant
31
9.3. correction of settings
Since PID parameters interact between them, one must introduce
changes only of one parameter. The best is to choose parameters
changing the value into a twice greater or twice smaller one.
During changes, one should be guided by following principles:
a) Slow jump answer:
– decrease the proportional band,
– decrease the integration and differentiation time.
b) Overshoots:
– increase the proportional band,
– increase the differentiation time.
c) Oscillations:
– increase the proportional band,
– increase the integration time,
– decrease the differentiation time.
d) Instability:
– increase the integration time.
