b) connection of a 2- and 3-wire transducer (Iout - output current, Uout - output voltage)
8. IMPORTANT TIPS – using the suppression systems
If an inductive load (e.g. contactor coil, transformer) is connected to the relay contacts, overvoltage and arc appear
often during opening as a result of discharge of energy accumulated in the inductance. Particularly harmful effects
of such overvoltage include reduced life of contactors and relays, destruction of semiconductors (diodes,
thyristors, triacs), damage or disturbance of control and measurement systems, emission of electromagnetic fields
causing interference with local devices. To avoid such effects, the overvoltage must be
reduced to a safe level. The easiest method is connecting a suitable suppression module
directly to the inductive load terminals. Generally, a suitable type of suppression system
should be selected for each inductive load. Modern contactors usually have factory-
installed suitable suppression systems. If they do not, a contactor with a built-in suppression system should be
bought. Temporarily, you can shunt the load using the RC system, e.g. R=47Ω/1W and C=22nF/630V. Connect the
suppression system to the inductive load terminals. This will limit burning of the relays contacts in the controller
and reduce the probability that they will get stuck.

10. SETTING OF THE CONFIGURATION PARAMETERS
All the controller's configuration parameters are saved in a non-volatile (permanent) internal memory.
When the device is switched on for the first time, an error message may be shown in the display due to the lack of
a sensor or the fact that the sensor that is connected or not one that is factory-programmed. In such an event, the
proper sensor or analog signal must be connected and the configuration must be programmed.
There are two parameter configuration methods:
1.
From the film keypad located on the front panel of the device:
- from the mode where the input measurements are displayed in the configuration menu (press the [UP] and
[DOWN] buttons simultaneously for more than 1 second) If parameter 49: Prot = on (password protection
is on) the display will show the message CodE, and then 0000 with the first digit blinking, use the buttons
[UP] or [DOWN] to enter the password (default parameter 48: PASS = 1111 ), to move to successive items
and to approve the code, use the [SET] button
- after entering the main configuration menu (with the message CnF) the upper display shows a mnemonic
name of the submenu (parameter groups: DiSP <-> in1 <-> in2 <-> etc.)
- use the[UP] or [DOWN] button to move to the relevant submenu and then use the [SET] button to approve
selection (the name of the parameter is displayed in the upper display and the value - in the lower display)
- by pressing the [UP] button, you can move to the next parameter, and by pressing the [DOWN] button - to
the previous parameter (e.g. inP <-> FiLt <-> dot <-> etc., the list of the configuration parameters
is presented in Table 10)
- to change the value of the current parameter, press briefly the [SET] button (the parameter blinks
in the edition mode)
- use buttons [UP] or [DOWN] to change the value of the edited parameter
- approve the changed value of the parameter by pressing the [SET] button or cancel it by pressing the [F] or
[UP] and [DOWN] buttons (the latter two must be briefly pressed simultaneously) - by pressing the [UP]
and [DOWN] buttons or the [F] button again, you will return to the main configuration menu (a higher level)
- to exit the configuration: press the [UP] and [DOWN] buttons for a long moment or wait approx. 2 minutes
2.
Use the RS485 or the PRG port (AR955/AR956 programmer) and the ARSOFT-CFG software (chapter 14):
- to connect the controller to a computer port and to start and configure the ARSOFT-CFG application;
- after the connection has been established, the current measured value is displayed in the window
of the software
- setting and viewing of the device parameters is possible in the parameter configuration window
- new parameter values must be approved with the Approve changes button
- the current configuration can be saved in a file or set using values read from a file
NOTE:
!
- before disconnecting the device from a computer, press the Disconnect device button (ARSOFT-CFG)
- in the event of no response:
- in the Program options check the configuration of the port and the MODBUS Address of the device
- make sure that the serial port drivers in the computer have been properly installed for the RS485 converter
or the AR955/AR955 programmer
- disconnect for a few seconds and then reconnect the RS485 converter or the AR956/AR955 programmer
- restart the computer
In the event of indications different than the actual value of the input signal, the ero and the sensitivity of a
sensor can be tuned: parameters 8: cAo1 and 15: cAo2 ( ero), and 9: cAG1 and 16: cALG (sensitivity).
To restore the factory settings, when the power supply is switched on press buttons [UP] and [DOWN] and hold
them until the password menu appears ( CodE ), and then enter the following code 0112. As an alternative, a file
with default configuration can be used in the ARSOFT-WZ1 software.
Do not perform configuration of the device ith the keypad and through the serial interface
(RS485 or AR955/AR956) at the same time.

1 . OUTPUT OPERATION CONFIGURATION
The programmable architecture of the controller enables using it in many fields and applications. Before the
operation of the device starts, it is necessary to set the parameters according to specific requirements (chapter 10).
A detailed description of configuration of the operation of outputs is given in chapters 12.1÷ 12.8. The default
(factory) configuration is the following: outputs 1 is related to input 2 and output 2 is related to input 2, control
mode ON/OFF with hysteresis, output 3 and the analog outputs are switched off (Table 10, Factory settings
column).
1 .1. CHANGING THE OUTPUTS SET VALUES
The simplest way to change the set value for output 1 (parameter 20: SEt1 or 42: HSEt when output 1 is in the
manual mode) is to use the [UP] button or the [DOWN] button. In the case of the other outputs, the quick menu
can be used (chapter 11). As an alternative, it is possible to change the set value in the parameter configuration
mode (using the methods described in chapter 10).
1 . . TYPES OF OUTPUT CHARACTERISTICS
The mode of operation of each output is programmed using parameters 19: Fun1 , 24: Fun2, and 29: Fun3 , chapter
10, Table 10.

14
a) basic operating characteristics of outputs
b) additional operating characteristics of outputs (applies only to outputs 2 and 3)
1 .3. ANALOG OUTPUT
The standard of the output signal is determined by parameter 33: AtYP (chapter 10, Table 10). The analog output
can work in one of the following modes: retransmission of measurement (parameter 34: outA = rEtr ), manual
mode (34: outA = hAnd ) and as an automatic control output (34: FunA = out1 ). In the mode of retransmission of
a selected measurement (32: coSA ) the output signal is proportional to the signal measured in the range set by

15
parameters 35: A-Lo and 36: A-Hi (e.g. 0 mA for the measured value 0 °C when A-Lo = 0 °C, 20 mA for 100 °C
when A-Hi = 100 °C and, as appropriate, 10 mA for the half of the range, i.e. 50°C ).
Manual operation (chapter 12.8) enables smooth change of the output signal in the range of 0-100% with an
increment of 1% and the initial value equal to the last value in the automatic mode (measurement retransmission
or control mode, applies to the controller firmware release starting from u-13, which is displayed when power is
switched on). In the control output mode, the control parameters and their functions are identical as in the case of
output 1 (the applicable parameters are 17: coS1 , 18: Fto1 , 19: Fun1 , 20: SEt1 , 21: H1, PID algorithm and tuning
parameters and process controller parameters). In the control mode, the range of variability of the analog signal is
continuous only for the PID algorithm (chapter 12.4), in the case of ON-OFF control with hysteresis, the output
assumes the limit values (lower or upper, e.g. 0mA or 20mA) without the intermediate values, which may be used
to switch on, e.g. the SSR relay.
1 .4. PID REGULATION
The PID algorithm enables achieving smaller control errors (e.g.
temperature) than the ON-OFF method with hysteresis. However, the
algorithm requires selecting the characteristic parameters for the specific
controlled object (e.g. a furnace). In order to simplify the operation, the
controller is provided with the advanced PID parameter selection
functions described in chapter 12.5. Also, it is always possible to
manually correct the settings (chapter 12.6).
The controller works in the PID mode when the proportionality range
(parameter 38: Pb ) is not a ero value. The location of the proportionality
range Pb in relation to the set value SEt1 is shown in drawings 12.4 a)
and b). The impact of the integrating and differentiating components of
PID control is determined by parameters 39: ti and 40: td . Parameter
41: tc determines the pulsing period for output 1 (P1/SSR1). If the PID
algorithm is implemented by the 0/4÷20 mA or 0/2÷10 V analog output,
the tc parameter is insignificant. Then the output signal may assume
intermediate values from the entire range of variability of the output.
Regardless of the type of the output, the correction of its state always
takes place every 1 s.
The principle of P-type regulation (proportional regulation) for output 1
is shown in figures d) and e) for the analog output figure c).
Fig. 12.4. Principle of the PID regulation:
a) location of the proportionality range Pb in relation to the set value
SEt1 for heating ( Fun1 = inv )
b) location of the proportionality range Pb in relation to the set value
SEt1 for cooling ( Fun1 = dir )
c) state of the 0/4÷20 mA or 0/2÷10 V analog output
d) filling coefficient for output 1 (P1/SSR1)
e) state of output 1 (for the measured value within the proportionality
range)

16
1 .5. AUTOMATIC PID PARAMETER SELECTION
The first step to use the PID parameter selection function is to choose the type of tuning (parameter 37: tunE ,
chapter 10). The tuning is started automatically when the control starts (after the power supply is switched on, and
by pressing the [F] function button, when parameter 50: Func = StSP , chapter 9.1). Moreover, tuning can be
stopped ( oFF ), and then started ( on ) at any time using the t-St function available in the quick menu (chapter
11). During the tuning (when the display shows, alternately with the measured value, the message tvnE ) the set
value must not be changed (20: Set1 or 30: SEt3 when 50: Func = SEt3 ).
The value of parameter 37: tunE determines the selection of the PID parameter selection method:
a) 37: tunE = Auto - automatic selection - the controller continuously checks if there are appropriate conditions
for starting the tuning and tests the object in order to select the proper method. The algorithm continuously
forces operation in the PID mode. The necessary condition for initiating the PID parameter selection procedure
is that the current measured value must be located outside of the insensitivity one defined as the sum of the
values of parameter 38: Pb and 21: H1 in relation to the set value 20: Set1 , as shown in figure 12.5.
Fig. 12.5. Location of the insensitivity
one for heating (19: Fun1 = inv )
and cooling (19: Fun1 = dir )
In order to avoid unnecessary activation of tuning, which may slow down the process, it is recommended to set
the highest possible value of H1, not less than 10÷30% of the range of variability of the process (e.g. the
measured temperature). Testing of the object with temporary switchoff of the output and the tunE message
also takes place in the insensitivity band if sudden changes in the measured value or set value are detected.
The choice of the parameter selection method depends on the nature of the initial conditions. In the case of a
stabili ed controlled value, the run-up (quick) method will be selected; in other cases, the oscillation method
(slower) will be selected.
Automatic selection enables optimum selection of the PID parameters for the current conditions at the object,
without the user's involvement. It is recommended for variable value regulation (disturbance of the conditions
determined during the operation due to the change of, e.g. the set value or the weight of the furnace batch).
b) 37: tunE = StEP – selection of parameters in the run-up phase (response to step function). During
determination of the object's characteristics, the algorithm does not cause any additional delay in reaching the
set value. This method is intended specifically for objects of stabili ed initial value of the controlled value (e.g.
temperature in a cold furnace). In order to avoid disturbing stabili ed initial conditions, before the automatic
tuning is switched on, the power supply of the operating element (e.g. a heater) should be switched off using an
external connector or the control start/stop function should be used (the [F] button). The power supply must be
switched on immediately after the tuning is started, in the output switch-on delay phase. If the power supply is
switched on later, an erroneous analysis of the object and improper selection of PID parameters will result.
c) 37: tunE = oSct – selection of parameters using the oscillation method. The algorithm consists in measuring
the amplitude and the period of oscillation on a slightly lower level (in the case of heating; higher level - in the
case of cooling) than the set value, thus eliminating the risk of exceeding the target value at the object testing
stage. During determination of the object's characteristics, the algorithm causes additional delays in reaching
the set value. This method is intended specifically for objects of unstable initial value of the controlled value (e.g.
temperature in a hot furnace).

17
The algorithms described in items b and c comprise the following steps:
- delay of output switch-on (approx. 15 s); - time for switching on the power supply of the operating element
(heating/cooling power, fan, etc.);
- determination of the object's characteristics;
- calculation and saving in the controller's permanent memory parameters 38: Pb , 39: ti , 40: td and 41: tc
- switching on the regulation with new PID settings;
Programmed interruption of the auto-tuning b or c (with the message Errt ) may take place, if the conditions for
proper operation of the algorithm are not met, such as:
- the initial value is higher than the set value for heating or lower than the set value for cooling;
- the maximum tuning time (4 hours) has been exceeded;
- the process value is changing too fast or too slowly.
It is recommended to restart the automatic tuning b or c after a significant change in the SEt1 threshold or the
controlled object's parameters (e.g. the heating/cooling power, the batch weight, the initial temperature, etc.).
1 .6. PID PARAMETER CORRECTION
The automatic tuning function correctly selects the PID regulation parameters for most processes; however,
sometimes it may be necessary to correct them. Due to the strong correlation between those parameters, only
one parameter should be changed and the impact of the change on the process should be observed:
a) oscillations about the threshold - increase the range of proportionality 38: Pb , increase the integration time 39: ti ,
reduce the differentiation time 40: td , (or change by a half the impulse period of output 1, parameter 41: tc )
b) slow response - decrease the range of proportionality Pb , differentiation times td and integration times ti
c) over-regulation - increase the range of proportionality Pb , differentiation times td and integration times ti
d) instability - increase the integration time ti .
1 .7. PROGRAMMED OPERATING CHARACTERISTICS (RAMPING)
Setting of parameter 43: rAMP (see chapter 10, Table 10) to value MAnv or Auto makes it possible to program the
device as a 4-step process controller, implemented through output 1, acting in accordance with the diagram
shown here (Fig. 12.7). This type of operation can be started both manually at any time (when parameter 43: rAMp
= MAnv or Avto ) and automatically ( rAMp = Avto ) at the time when the control is started (after power supply is
switched on and by using the [F] function button when parameter 50: Func = StSP , chapter 9.1). In order to
manually switch on ( on ) or switch off ( oFF ) the process controller, use the P-St function available in the quick
menu (chapter 11).
Fig. 12.7. Diagram showing the operation of the 4-step process controller

18
The successive steps of the process are shown on any display by messages shown every few seconds, alternately
with the current displayed value:
- Pr-1 - stage 1 - reaching the value of threshold 20: SEt1 with set gradient (44: rAr) - ramping
- Pr-2 - stage 2 - implementation of the 1st holding time 45: th1 on level SEt1 (with hysteresis 21: H1 ), value of
parameter th1 = 0 maintains step Pr-2 permanently
- Pr-1 - stage 3 - reaching the value of threshold 25: SEt2 with full power
- Pr-2 - stage 4 - implementation of the 2nd holding time 46: th2 on level SEt2 (with hysteresis 26: H1 ), value of
parameter th1 = 0 maintains step Pr-2 permanently
- End - end of process (output 1 is switched off permanently)
Moreover, it is possible to relate to the process outputs 2 or 3 when parameter 24: Fun2 or 29: Fun3 is equal to:
rEon - switching the output on after the end of the process (switched off in the course)
rEoF - switching off the output after the end of the process (switched on in the course)
rEP3 - switching on the output for steps Pr-3 and Pr-4
1 .8. MANUAL AND REMOTE CONTROL FUNCTION
The manual mode enables setting the value of the output signal in the entire range of its variability (0-100%), thus
enabling operation in an open regulation loop (no automatic coupling between the measured value and the
output signal). Manual operation is available individually for each output of the controller and is programmed
using parameters 19: Fun1 , 24: Fun2 , 29: Fun2, and 34: Fun3 , chapter 10, Table 10. Also, the outputs can be
configured for quick (unconditional) manual mode controlled by:
- the [F] function button, by programming, as appropriate, parameter 50: Func (chapter 9.1),
- measurement error of the sensor (range exceeded or a defect), when 18: Fto1 , 23: Fto2,
or 28: Fto3 is equal to hAnd
In the case of bi-state outputs (1, 2, 3), the change of the output signal consists in setting the filling coefficient
(using parameter 42: HSEt ) with impulse period defined by parameter 41: tc. The set value of the manual mode
42: HSEt = 0 stands for a permanently switched off output; value 100 stands for a permanently switched on
output. The value can be set directly using the [UP] or [DOWN] button (only in the case of output 1, chapter 12.1)
or using the quick menu (chapter 11), or alternatively, in the parameter configuration mode (from the membrane
keypad or remotely using the RS485 or PRG serial port, chapters 10, 14-16 ).

14. CONNECTING THE CONTROLLER TO A COMPUTER AND AVAILABLE SOFTWARE
It may be useful (or necessary) to connect the controller to a computer in the following situations:
- remote monitoring and recording of current measurement data and process (status of the outputs) control;
- quick configuration of parameters, to include copying of settings to other controllers of the same type
In order to establish communication over long distances, it is necessary to establish a connection in the RS485 standard
with an available port in the computer (directly or using an RS485 converter), as described in chapter 15. Moreover, as a
standard, the controllers are equipped with a PRG port which enables connecting to a computer using an AR955/956
programmer (without galvanic isolation, cable length approx. 1.2 m). Both the programmer and the RS485 converter
require installation of the supplied serial port drivers on the computer. Communication with devices is effected using a
protocol compatible with MODBUS-RTU (chapter 16). The following applications are available (on a CD supplied with the
AR955/956 programmer or to be downloaded from the Internet at www.apar.pl, Download section, for operating
systems Windows Vista/7/8/10):

- creation on the disk of a "cfg" file with the current configuration of the parameters for future
use (copying of configuration)
- the software requires communication with the controller via the RS485
or PRG (AR955/AR956) port
The detailed descriptions of the aforementioned applications can be found in the installation folders.
NOTE:
Before establishing the connection, make sure that the MODBUS address of the device (parameter 51: Addr ) and
the speed of transmission (52: br ) are the same as the settings of the software. Moreover, in the software options,
set the number of the COM serial port in use (in the case of the RS485 converter or the AR955/AR956 programmer
it is the number assigned by the operating system during installation of the drivers).

15. RS485 COMMUNICATION INTERFACE (acc. to EIA RS-485)
It may be useful (or necessary) to connect the controller to a computer in the following situations:
The installation specification for the RS485 interface is the following:
Maximum cable length - 1 km
Maximum number of devices in a RS485 line - 30, in order to increase the number, use RS485/RS485
amplifiers
Termination resistors when the MASTER is at the start of the line (see the figure above):
-at the start of the line - 2 x 820 Ω to the ground and +5 V of the MASTER, and 150 Ω between the lines,
-at the end of the line - 150 Ω between lines,
Termination resistors when the MASTER is in the center of the line:
-at the converter - 2 x 820 Ω, to the ground and +5 V of the converter,
-at both ends of the line - 150 Ω each between lines.
Equipment from different manufacturers that form the RS485 network (e.g. RS485 converters/USB) may have
integrated polari ing and terminating resistors; in such a case there is no need to use external elements.
During configuration of the network, make sure to observe the cable installation recommendations given in
chapter 2.
