. SAFETY RULES
Before using the device, please read this manual carefully, and:
a) in order to avoid electric shock or damage to the device mechanical and electrical assembly
should be commissioned to qualified personnel
b) before turning on the power, make sure that all cables have been connected correctly
c) before modifying cable connections, disconnect the voltage connected to the device
d) ensure proper working conditions, compliant with the technical data of the device (chapter 4, supply voltage,
humidity, temperature, etc.), do not expose the device to direct and strong influence of heat radiation
2. ASSEMBLY RECOMMENDATIONS
The device has been designed to provide an adequate level of resistance to most of the disturbances that can
occur in industrial and home environments. In environments with an unknown level of interference, it is
recommended to use the following measures to prevent any possible disruption of the device's operation:
a) do not supply power to the device from the same lines as large capacity devices without proper mains filters
b) use shielding of power, sensor and signal wires, and screen-grounding
should be single-point, made as close as possible to the device
c) avoid laying measuring (signal) wires in the immediate vicinity and parallel to
power and supply cables
d) it is recommended to twist signal wires in pairs or use a ready UTP wire
e) Use the same cables for resistance sensors in a -wire connection
f) avoid the proximity of remotely controlled devices, electromagnetic meters, high power loads,
loads with phase or group power control and other devices generating large impulse noise
g) ground or neutralize the metal rails on which the rail devices are mounted
Before starting working with the device, remove the protective foil of the LED display.

7.1. FUNCTION KEYS AND BINARY INPUT
Independent function keys [F] (not available in the AR602.B) and [SET] as well as the BIN binary input are used to
quickly run the programmed functions (with parameters 64: Fun F, 66: FunS and 65: Funb , described in chapter 8).
The BIN digital input cooperates with a bistable signal, i.e. the supplied signal (voltage or switch) must be
permanent (on/off type, active level: short-circuit or < 0.8V). Moreover, BIN has priority higher than the [F] and
[SET] keys. Activating or stopping the function is signaled by appropriate messages on the lower display
(described in Table 8 and chapter 10). The action for [F] and [SET] is performed only in the mode with
measurement display (after holding time> 1.5 sec), for BIN - always (in every operating state).
8. SETTING CONFIGURATION PARAMETERS

CodE will appear on display, followed by 0000 with the first digit flashing, with the [UP] or [DOWN] key
enter the access password (default parameter 70: PASS = 1111), to move to the next positions
and confirm the code use the [SET]key, to cancel the changes use the [UP]+[DOWN] or [F]keys,
- after entering the main configuration menu (with the message ConF ) the upper line shows
the mnemonic name of the submenu (parameter groups: inCo <->out1<-> out2 <-> etc.), the bottom line is
dimmed or displays none (no module, depending on the hardware version of the controller),
- use the [UP] or [DOWN] keys to select the appropriate submenu, and then press [SET] to confirm
the selection (the name of the parameter is now visible on the upper line and the value on the lower line of the
display),
- the [UP] key takes you to the next parameter, [DOWN] to the previous one (eg: inP <-> LirE <-> cJtE <-> etc.,
only parameters compatible with the hardware version are available, a summary list in Table 8),
- to change the value of the current parameter, briefly press the [SET] key (flashing in edit mode),
- use the combination of [UP], [DOWN] and [SET] keys to change the value of the edited parameter
(with a step of changes x1 or x10 or load the default value of a parameter, description of the function in chapter 7,
points b and c),
- confirm the changed value of the parameter with the [SET] key or cancel it with the [F] or [UP]+[DOWN] keys,
- pressing [UP]+[DOWN] or [F] again causes the return to the main configuration menu (one level up),
- exit from configuration: long press of [UP]+[DOWN] keys or automatically after approx. 2 minutes of inactivity
2. Remotely through the USB port, RS485 or Ethernet and the ARSOFT-CFG computer program (chapter 11):
- connect the controller to the computer port, run and configure the ARSOFT-CFG application,
- after establishing the connection, the program displays the current measurement, the icon [Tx/Rx] signals
transmission (chapter 7, point d)
- setting and viewing device parameters are available in the parameter configuration window
- new parameter values must be confirmed with the Approve changes key
- the current configuration can be saved to a file or set with values read from the file
NOTICE:
- before disconnecting the device from the computer, use the Disconnect the device (ARSOFT-CFG) key
- in the absence of a response:
- check the settings in Edit of configuration (Connection type, COM Port, MODBUS address of the device, etc.)
- for USB, check whether the drivers for the serial port in the computer have been correctly installed (see section 11)
- disconnect for a few seconds and reconnect the regulator or the RS485 converter to the USB port of the
computer
- restart the ARSOFT-CFG and/or the computer
If there is a discrepancy between the indications and the actual value of the input signal, it is possible to tune the
zero and sensitivity to a given sensor: parameters 7: cALo (zero) and 8: cALG (sensitivity).
In order to restore the factory settings, press the [UP] and [DOWN] keys during start until the password entry
menu appears (CodE ), and then enter the code 0112. Alternatively, you can use the file with the default
configuration in the ARSOFT-CFG program.

(3) - for FiLt = 1 the response time is 0.25 second, for FiLt = 20 at least s. Higher degree of filtration

used in the content of the published MQTT message (chapter 11.1) and by the DHCP client (when 77: EtMo = Auto).
9. OUTPUT OPERATION CONFIGURATION
Programmable architecture of the controller allows its use in many fields and applications. Before starting the
device operation, set the parameters to individual needs (such as control algorithms 9/16/2 : ctY1/2/3 , types of
control/alarms 10/17/24: Fun1/2/3 , setpoints 11/18/25: SEt1/ 2 / 3 and other described in Table 8, chapter 8). If
there is a need to start the control for a specific time (timer function), you should additionally use the possibilities
offered by the program control (chapter 9.6).
A detailed description of configuration of the operation of outputs is included in chapters 9.1÷9.7.
The default (factory) configuration is as follows: outputs 1, 2 and (alarm for AR602.B) in the heating control
mode (ON-OFF algorithm with hysteresis), the analog output is disabled (Table 8, factory settings column).
9.1. CHANGE OF SETPOINTS FOR OUTPUTS. QUICK ACCESS MENU.
In the measurement display mode (PV), the bottom line shows the setpoint SP for the selected output or the
bargraph or it can be blanked (selection with parameter 7 : dibo , chapter 8). The easiest way to change the SP
setpoint visible in this mode is to use the combination of the [DOWN], [UP] and [SET] keys described in chapter 7
(with a step of x1 or x10). All SP setpoints (i.e. parameters 11/18/25: SEt1/2/3 and optionally 67: HSEt - when the
output is in manual mode) are available in the quick access menu and in the parameter configuration mode (ways
of changes are described in chapter 8). The quick access menu is entered by pressing the [SET] key, without the
need to enter the password. Optionally, to disable fast SP changes (with the message bLoc), you can use
parameter 68: bSEt (Table 8). Exit from the menu takes place after long pressing the [DOWN] + [UP] keys or
automatically after 7 seconds of inactivity.
9.2. ANALOG OUTPUT (mA/V)
The standard of the output signal is set by parameter 0: AtYP (chapter 8, Table 8, point III). The analog output can
be programmed (with parameter 1: FunA) to work in one of the following modes: retransmission of the PV meas-
urement or setpoint SP and as a control output associated with the parameters of the selected output 1, 2 or .
In the measurement or setpoint retransmission mode , the output signal is proportional to the PV or SP signal
within the range set with parameters 2: ArLo and : ArHi (e.g. 0mA for the measured value 0°C when ArLo =
0°C, 20mA for 100°C when ArHi = 100°C and respectively 10mA for the half of the range, i.e. 50°C ). In other words,
!

18
the output operating in the retransmission mode enables the conversion of the input signal to the output signal
(in the range ArLo ÷ ArHi ). In the control output mode, the control parameters and functions are the same as for
the related output 1/2/ , but the variability range of the analog signal is continuous (0 ÷ 100%) only for the PID
algorithm (chapter 9.3) and manual operation, for the control of ON-OFF type with hysteresis, the output has
extreme values (bottom or upper value, e.g. 0mA = 0% = OFF or 20mA = 100% = ON) without intermediate values,
which can be used e.g. to activate the SSR relay.
The values of the output signal (mA/V) can be presented in the form of a bargraph on the bottom line of the
display (parameter 7 : dibo = bArA) or read from the level of MODBUS-RTU/TCP and MQTT protocols, chapter 11.
Moreover, it is possible to correct (calibrate) the range of changes of the output signal (parameters 4: cbot and
5: ctoP).
9.3. PID CONTROL
The PID algorithm makes it possible to obtain smaller temperature
control errors than the ON-OFF method with hysteresis. However,
this algorithm requires selection of parameters characteristic for a
specific regulation object (eg a furnace). In order to simplify the
handling, the controller is equipped with advanced functions of PID
parameter selection, described in chapter 9.4. In addition, it is always
possible to manually adjust the settings (chapter 9.5).
The PID control for a given control output is active when one of the
three sets of PID parameters is selected (with the parameter
ctY1/2/3 , description in chapter 8, Table 8, point II, or with the
parameter PSE1/2/3, point V), i.e. PiD1/2/3.
The position of the proportional band Pb (Pb1/2/3, Table 8, point IV)
in relation to the setpoint SP (SEt1/2/3) is shown in Figures 9. a)
and b). The parameters ti1/2/3and td1/2/3 are responsible for the
influence of the integral and derivative element of the PID control.
The parameter PEr1/2/3 sets the pulse period Tc for the P/SSR
output (it is also the time of its status update), while oPF1/2/3 the
available power used for selecting PID parameters. If the PID
algorithm is implemented by the 0/4 ÷ 20mA or 0/2 ÷ 10V analog
output, the Tc period is irrelevant. The mA/V output signal is then
updated every 1 s and it can adopt intermediate values from the
entire range of output variability (0÷100%).
The principle of operation of the P-type control (proportional
control) for the P/SSR output is shown in figures d), e) for the analog
output, figure c).

9. . AUTOMATIC SELECTION OF PID PARAMETERS
In order to use the PID parameter selection function for a given control output (1/2/ ), first select the PID
parameters set (using the method described in chapter 9.3) to which the calculated data will be saved, and then
set the type of auto-tuning (with the parameter tvn1/2/3 description in chapter 8, Table 8, point IV). The auto-
tuning is activated at the start of the control (automatically after switching the supply on or manually using the
[F], [SET] function keys or the BIN binary input programmed as the start/stop of outputs operation, chapter 7.1).
Autotuning is performed independently for each of the outputs with the maximum available power (defined by
the parameter oPF1/2/3 Table 8, point II) and is signaled by cyclic messages tun1/2/3 (for the StEP method ) or
tuo1/2/3 (for oSct) or flashing of the upper right dot during the object analysis for Auto (chapter 7, point d).
The value of the parameter 6/40/44: tvn1/2/3 determines the choice of the PID parameter selection method:
a) tvn1/2/3 = Auto (continuous mode, smart logic) - the controller continuously checks whether there are
conditions for starting the tuning and tests the object in order to select the appropriate method. The algorithm
continuously forces operating in the PID mode. The necessary condition to initiate the PID parameter selection
procedure is the location of the PV current measured value outside the dead band defined as the sum of the
parameters value of the Pb proportional band and the associated hysteresis H in relation to the SP setpoint , as
in figures 9.4.
Fig.9.4.
Location of the deadband for the type of
heating type control (Fvn1/2/3 = indH)
and cooling type control (Fvn1/2/3 = dirC)
In order to avoid unnecessary activation of tuning, which may delay the course of the process, it is
recommended to set the hysteresis H to the highest possible value, not less than 10 ÷ 0% of the process value
variation range (e.g. measured temperature). Testing of the object with the short disactivation of the output and
the flashing of the upper right dot also takes place in the dead band in case of detecting sudden changes of the
measured value PV or the setpoint SP. The choice of the parameter selection method depends on the nature of
the initial conditions. For a stabilized controlled quantity, the step response method (fast) will be selected,
otherwise the oscillation (longer) method will be activated.
Automatic selection (continuous mode) enables the optimal selection of PID parameters for the current
conditions on the site, without user intervention. It is recommended for variable value control (disturbance of
set conditions during operation by modification of e.g. the setpoint SP or the furnace batch).
b) tvn1/2/3 = StEP (step response method, fast)- selection of parameters in the step stage (response to step-
forcing function). While determining the characteristics of the object, the algorithm does not cause an
additional delay in reaching the setpoint SP. This method is dedicated to facilities with stabilized initial
controlled value (e.g. temperature in a cold furnace). In order not to disturb the initial conditions, before starting
the auto-tuning, turn off the power supply of the actuator (eg heater) with an external switch or use the control
start/stop function (keys [F], [SET] or BIN input). The power supply should be switched on immediately after
starting the tuning, in the delay phase of switching on the output. Turning on the power at a later stage will
result in an incorrect analysis of the object and, as a result, incorrect selection of PID parameters.
c) tvn1/2/3 = oSct (oscillation method, longer)- selection of parameters using the oscillation method. The
algorithm involves the measurement of the oscillation amplitude and period at a slightly lower level (for heating
or a slightly higher level for cooling) than the setpoint SP in order to eliminate the danger that the target value
will be exceeded during the object test stage. While determining the characteristics of the object, the algorithm
causes additional delays in reaching the setpoint. This method is dedicated to objects with unstable initial
controlled value (e.g. temperature in a hot furnace).
The algorithms from subpoints b and c consist of the following stages:
- delay in activating the output (approx.15 seconds - time for switching on the power of the actuator, i.e. heating/
cooling power, fan, etc.) and determining the characteristics of the object,

20
- calculation and permanent saving of parameters (Pb, Ti, Td to the selected PID and Tc set, i.e. PEr1/2/3 , chapter
8),
- switching on the control for a given output with new PID settings
The program can discontinue the autotuning b or c (with the EtP1/2/3 message) in the following situations:
- the initial value of PV is higher than the setpoint SP for heating or lower than the setpoint for cooling,
- the SP setpoint has been changed or the measured value of the PV process changes too quickly or too slowly,
- the maximum tuning time (4 hours) has been exceeded
It is recommended to restart the autotuning b or c after a significant change in the SP threshold or the
parameters of the control object (eg heating/cooling power, batch mass, initial temperature, etc.).
Autotuning does not work in program control (process controller) and valve control (servo) mode.
9.5. CORRECTION OF PID PARAMETERS
The autotuning function correctly selects the PID regulation parameters for most processes, but sometimes it may
be necessary to correct them. Due to the strong interdependence of these parameters (described in chapters 9.3
and 8, Table 8), only one of them should be changed and the impact on the process should be observed:
a) oscillation around the threshold - increase the proportional band Pb, increase the integration time Ti , decrease
differentiation time Td , (or reduce the pulse period of the output by half, parameter Tc )
b) slow response - reduce the Pb proportional band, Td differentiation time and Ti integration time
c) overshoot - increase the Pb proportional band, Td differentiation time and Ti integration time
d) instability - increase the integration time Ti.
9.6. PROGRAMMED WORK CHARACTERISTICS. SAMPLE CONFIGURATION.
The controller allows you to create a control program (process controller) consisting of a maximum of 6 segments
( stages configured with the parameters described in chapter 8, Table 8, point V). Each stage (1/2/ ) operates in
accordance with the control parameters of the assigned setpoint SP (1/2/ ), description in Table 8, point II.
A program can be assigned to any of the control outputs (1/2/ ) with parameter 9/16/2 : ctY1/2/3 set to the value
PrGc. Additionally, it is possible to define an auxiliary output ( PrGA ), which can be useful for signaling the
operating status for individual program stages as well as for switching on additional devices (fans, additional
heating sections, etc.) with the manual operation option (when parameter 52/57/62/6 : ASt/1/2/3/E = hAnd).
The program starts at the moment of starting the control (automatically after switching on the power or manually
using the [F], [SET] function keys or the BIN binary input programmed as the start/stop of outputs, chapter 7.1)
and is always performed from the beginning (1st stage/segment). Successive stages of the process (1/2/ ) are
signaled by the messages Pr-1/2/3 appearing every few seconds, alternately with the current setpoint SP (or other
programmed parameter 7 : dibo) and optionally with the remaining stage time (in hh: mm format with m or 00:
ss unit when time<1min, without unit). During the countdown, the upper right dot flashes (chapter 7, point d). The
program ends with message PEnd and switching off the control output.
Diagram of an exemplary program configuration
Fig.9.6. Diagram of a sample program
consisting of 4 segments for the heatingtype
control (Fvn1/2/3 = indH) is presented in the
diagram on the right. At the start of the process
(control) , the initial setpoint for segment 1 is the
current measured value (PV0, e.g. 25°C), target
setpoint SPC = Set1 , which is achieved with the
rate (slope) N1 = GrA1 (e.g. 25°C/ min). After
reaching the SPC value and control at this level by the T2 time set for the 2nd segment = tiM1, the move to the rd
section takes place, for which the cooling function with the speed N =GrA2 is provided
(e.g. -10°C/min) up to SPK level = Set2. During cooling, an auxiliary output can be used to switch on e.g. a fan. The
program is stopped (with switching off the control output) after reaching the SPK and going to the 4th segment.
