b) connecting 2- and 3-lead transmitter (Iout - current, Uout – output voltage)
8. IMPORTANT TIPS – u ing the uppre ion y tem
!
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. o avoid such
effects, the overvoltage must be reduced to a safe level. he 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. emporarily, 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. his will limit burning of the relays contacts in the controller
and reduce the probability that they will get stuck.

Function button [F] (unavailable in AR602) and binary input BIN perform the same function programmable by
parameter 34: Func (section 10). he binary input cooperates with the bistable signal, i.e. the received signal
(voltage or switch) must be of durable character (on/off type). In addition, the [F] is inactive when the BIN is active
(short-circuit or voltage <0.8V). Starting and stopping of the function is signalled by relevant message on the
bottom display (described in able 9.1).

10. SETTING THE CONFIGURATION PARAMETERS
All configuration parameters are stored in a non-volatile internal memory. When the controller is switched on for
the first time, an error message may appear indicating that there is no sensor or that the sensor is different than
programmed. Connect the right sensor or perform the configuration programming.
here are two methods of parameter configuration:
1 Using the keypad on the front panel:
−from the measurement display mode go to the configuration menu (simultaneously press [UP] and
[DOWN] buttons for longer than 1 s). If the parameter 33: PPro = on (password protection on), the display
will show the message CodE and then 0000 with the first digit flashing. Use the [UP] or [DOWN] buttons
to enter the access password (default parameter 32: PASS = 1111 ). Use the [SET] button to go to
successive positions and to approve the code;
−after entering the configuration menu (with the ConF message) the main display shows the mnemonic
name of the parameter (inP <-> FiLt <-> dot <->, etc.), and the bottom one its value;
−use the [UP] button to go to the next parameter, and the [DOWN] button to return to the previous
parameter (the list of all parameters is given in table 10);
−to change the value of selected parameter, briefly press [SET] (flashing in the edit mode);
−change the value of parameter using [UP] or [DOWN] buttons;
−confirm new value by pressing [SET] or cancel: [UP] and [DOWN] (press simultaneously briefly) and the
display will again show the parameter name;
− to exit the configuration menu: press [UP] and [DOWN] simultaneously for a longer time. he controller will
exit the configuration menu automatically after about 2 min. of inactivity.
2 Via the RS485 port or PRG (AR955 programming device) and the ARSOF -WZ1 application (section 14):
- connect the controller to the computer, start and configure the ARSOF -WZ1 application
- when the connection is made, the program window will show the current measured value
- setting and viewing of parameters is possible in the parameter configuration window
- press the Accept Change button to approve new values
- current configuration can be saved in a file or set using the values read from the file
- file with ready configuration can also be created using the ARSOF -WZ4 application (section 14)

11
NOTE:
!
- before disconnecting the controller from the computer press the Di connect Device button (ARSOF -WZ1)
- if the program does not respond:
-in Program Option check the port configuration and the MODBUS device addre
-make sure that the serial port drivers in the computer have been correctly installed for the
RS485 converter or the AR955 programming device
-disconnect the RS485 converter or the AR955 programming device for a few seconds and then

12. OUTPUTS CONFIGURATION
Programmable architecture of the controller allows it to be used in many fields and applications. Before using the
device, its parameters need to be customized (section 10). he detailed description of outputs configuration is
given in sections 12.1 ÷ 12.8. he default factory configuration is as follows: outputs 1 and 2 are in the ON-OFF
mode with hysteresis, output 3 and analogue outputs are off ( able 10, Default settings column).
12.1. CHANGING THE OUTPUTS SET VALUES
In the measurement mode the top display shows the measured value and the bottom one the output 1 set value
(parameter 9: SEt1 or 26: HSEt when the controller is in manual mode). he easiest way to change the set value is
to use the [UP] or [DOWN] buttons. Quick access menu (section 11) can be used for other outputs. As an
alternative, the modification of each set value is available in the parameter configuration mode, using methods
described in section 10.

15
12.2. TYPES OF OUTPUT CHARACTERISTICS
ype of operation of each output is programmed using the parameters 8: out1, 12: out2, and 15: out3,
section 10, able 10.
a) basic outputs characteristics curves
b) additional outputs characteristics curves (only for outputs 2 and 3)
NOTE: * H3 is constant and equals 0.2°C (2 units), not subject to configuration

16
12.3. ANALOGUE OUTPUT
he output signal standard is determined by parameter 17: AtYP (section 10, able 10). he analogue output can
be used in one of the following modes: measurement retransmission (parameter 18: outA = rEtr), manual (18:
outA = hAnd) and as an automatic control output (18: outA = cont).
In the measurement retransmission mode, the output signal is proportional to the signal measured in the range
set by parameters 19: A-Lo and 20: A-Hi (e.g. 0mA for the measured value 0 °C when A-Lo = 0°C , 20mA for 100 °C
when = 100°C, and correspondingly 10mA for the half range, i.e. 50°C ) . In other words, in the retransmission
mode the output converts the input signal to the output signal (in the A-Lo ÷ A-Hi range). Manual mode (section
12.8) allows a smooth conversion of the input signal into the output signal in the 0 ÷ 100% range with 1%
increment and initial value equal to the last value in automatic mode (measurement retransmission or control).
In the automatic control mode, the parameters and functions are identical as for output 1 (applicable are 7: Fto1 ,
8: ovt1 , 9: SEt1 , 10: H1 , algorithm and PID tuning parameters and the process control).
In the control mode, the analogue signal variation range is continuous only for the PID algorithm (within the
proportionality range, section 12.4), in case of the ON-OFF mode with hysteresis the output has the extreme
values (low or high value, e.g. 0mA or 20mA), with no intermediate values.
12.4. PID CONTROL
he PID algorithm gives smaller control errors (e.g. temperature) than the
ON-OFF method with hysteresis. However, this algorithm requires the
selection of typical parameters for a given controlled facility (e.g. a
furnace). o simplify the use, the controller is equipped with advanced
functions of selecting the PID parameters which are described in section
12.5. In addition, it is always possible to correct the settings manually
(section 12.6).
he controller operates in the PID mode when the proportionality range
(parameter 22: Pb) is non-zero. Relation between the proportionality
range Pb and the set value SEt1 is shown in figures 12.4 a) and b). he
impact of the integration and differentiation is defined by the
parameters 23: and 24: . he parameter 25: determines the
pulsing period for output 1 (P1/SSR1). When the PID algorithm is effected
by the 0/4÷20mA or 0/2÷10V analogue output, the parameter is
irrelevant. In that case, the output signal can have any intermediate value
from the entire output variability range.
Regardless of the output type, the output status is always adjusted
every 1s.
he principle of operation of the P type (proportional) control for output
1 is shown in figures d), e), for analogue output in figure c).
Fig. 12.4. PID control - principle of operation:
a) Relation between the proportionality range Pb and the set value
SEt1 for heating (ovt1 = inv)
b) Relation between the proportionality range Pb and the set value
SEt1 for cooling (ovt1 = dir)
c) status of analogue output 0/4÷20 mA or 0/2÷10V
d) filling ratio for output 1 (P1/SSR1)
e) status of output 1 for measured value within the proportionality range

17
12.5. AUTOMATIC SELECTION OF PID PARAMETERS
he first step to use the function of PID parameters selection is to choose the type of tuning (parameter 21: tunE,
section 10). he tuning will start automatically with start of control (after powering up, and also by pressing the
button [F], or by binary input BIN when parameter 34: Func = StSP, section 9.1). in addition, the tuning can be
stopped (oFF), and then restarted (on) at any time by using the function t-St available in the quick access menu
(section 11). When the tuning is in progress (i.e. when the display alternately shows the set value and the tvnE
message) the set value should not be changed (9: Set1 or 16: SEt3 when 34: Func = SEt3).
Value of parameter 21: tvnE determines the method of selecting the PID parameters:
a) 21: tunE = Auto - automatic selection – the controller continuously checks if there are conditions to start the
tuning and tests the facility to find a suitable method. he algorithm incessantly enforces the PID mode
operation. he necessary condition to initiate the PID parameters selection is the measured value being out of
the insensitiveness zone which is defined as the sum of parameter 22: Pb and 10: H1 in relation to set value 9:
Set1, as in figure 12.5.
Fig.12.5. Insensitiveness zone for
heating (8: ovt1 = inv) and
cooling (8: ovt1 = dir)
o avoid an unnecessary start of tuning, which may delay the process, it is recommended to set the H1 relatively
high, at least at 10÷30% of the process variability range (e.g. measured temperature variability range). he
facility testing with temporary output off and the tvnE message takes place also in the insensitiveness zone if
rapid changes of measured or set value are detected.
he method of parameters selection depends on the initial conditions. he fast step method will be used in case
of stabilized controlled value, otherwise the slower oscillation method will be applied.
he automatic selection ensures optimum PID parameters for current conditions in the facility, without the
user’s intervention. It is recommended for variable value control (disturbance of set conditions during operation
by modification of e.g. the set value or the furnace batch).
b) 21: tunE = StEP – selection of parameters in the step stage (response to step function). While determining the
characteristics of the object, the algorithm does not cause an additional delay in reaching the set value. his
method is dedicated to facilities with stabilized initial controlled value (e.g. temperature in a cold furnace). In
order not to disturb the stabilized initial conditions, before starting the autotuning, turn off the actuator’s (e.g.
the heater) power supply using an external switch, or use the control start/stop function [F] button or BIN
input). urn on the power supply again immediately after the autotuning starts, during the output activation
delay phase. If the power supply is turned on later, the facility analysis will be incorrect and consequently the
PID parameters will not be selected correctly.
c) 21: tunE = oSct – selection of parameters using the oscillation method. he 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 set value in order to eliminate the danger that the target value will be exceeded
during the facility test stage. While determining the characteristics of the object, the algorithm causes an
additional delay in reaching the set value. his method is dedicated to facilities with unstable initial controlled
value (e.g. temperature in a hot furnace).
he algorithms from b and c comprise the following stages:
-output activation delay (about 15s) – time to power up the actuator (heating/cooling power, fan, etc.);
-determination of the facility characteristic curve;
-determination and saving in the controller’s non-volatile memory of parameters: 22: Pb , 23: ti , 24: td
and 25: tc
-activation of control with new PID settings.

18
he program can discontinue the autotuning b or c (with the Errt message) if the conditions for correct
algorithm operation are not met:
-initial value is higher than the set value for heating or lower for cooling;
-maximum autotuning duration (4 hours) has been exceeded;
-process value changes too quickly or too slowly.
It is recommended to perform the autotuning b or c after a significant change of the SEt1 threshold or the
controlled facility parameters (e.g. heating/cooling power, charge, initial temperature, etc.).
12.6. ADJUSTMENT OF PID PARAMETERS
he autotuning function correctly selects the PID control parameters for most processes, but sometimes the
parameters need adjustment. Due to a strong interdependence of these parameters, adjust only one of them and
observe the impact on the process:
a) oscillation around the threshold – increase the proportionality range 22: Pb, increase integration time 23: ti,
decrease differentiation time 24: td, (possibly reduce the output 1 pulsing time by half, parameter 25: tc);
b) slow response - reduce the proportionality range Pb, differentiation time td and integration time ti;
c) overshoot - increase the proportionality range Pb, differentiation time and integration time ti
d) instability – increase the integration time ti.
12.7. PROGRAMMABLE CHARACTERISTICS (RAMPING)
Setting of parameter 27: rAMP (see section 10, able 10) to MAnv or Auto allows to program the device as a 4-
step process controller, implemented by output 1, according to the diagram in presented fig. 12.7. his mode of
operation can be started manually at any time
(when parameter 27: rAMp = MAnv or Avto) and
automatically (rAMp = Avto) when the control
process begins (after powering up, and also using
the [F] button or BIN binary input when parameter
34: Func = StSP, section 9.1). o manually turn the
process controller on (on) or off (oFF)use the P-St
function available in the quick access menu
(section 11).
F
Fig.12.7. 4-step process controller operation diagram
Successive process stages are signalled by the messages displayed alternately with the set value (Set1 or Set2):
- Pr-1 - stage 1 – reaching the value of threshold 9: Set1 with the set gradient (28: rAr)) - ramping
- Pr-2 - stage 2 – implementation of the 1
st
hold time 29: at the Set1 level (with hysteresis 10: H1),
the value of parameter th1 = 0 keeps permanently the stage Pr-2
- Pr-3 - stage 3 – reaching the value of threshold 13: Set2 at full power
- Pr-4 - stage 4 - implementation of the 2
nd
hold time 30: th2 at the Set2 (with hysteresis 14: H2 )
the value of parameter th2 = 0 keeps permanently the stage Pr-4
- End - end of process (output 1 permanently off)
In addition, it is possible to assign the output 2 or 3 to the process when parameter 12: out2 or 15: out3 equals:
rEon - output on after process end (off during the process)
rEoF - output off after process end (on during the process)
rEP3 - output on for stages Pr-3 and Pr-4
Operation in the process control mode precludes the PID autotuning and PID adjustment.

12.8. MANUAL AND REMOTE CONTROL OPTION
he manual mode allows to set the output signal over its whole range (0 ÷ 100% ), and consequently the enables
the open control loop operation (no automatic relationship between the measured value and the output signal).
he manual mode is available independently for each controller output and is programmable by the parameters
8: out1, 12: out2,15: out3 and 18: outA section 10, able 10. In addition, output can be configured for a quick
(unconditional) manual mode controlled by:
- the function button [F] or binary input BIN, by suitably programming the parameter 34: Func (section 9.1),
- sensor measuring errors (exceeding the range or failure), when 7: Fto1 or 11: Fto2 is equal to hAnd
In case of switching outputs (1, 2, 3), the change of output signal involves setting the filling ratio (using the
parameter 26: HSEt ) with pulsing period defined by parameter 25: tc he manual mode set value 26: HSEt = 0
means that the output is permanently off, value 100 means it is permanently on. his value can be set using the
[UP] and [DOWN] buttons (only for output 1, section 12.1) or the quick access menu (section 11), and alternatively
in the parameter configuration mode (from keypad or remotely via the RS485 serial port or PRG, sections 10, 14 ÷
16 ).

14. CONNECTING TO THE PC AND AVAILABLE SOFTWARE
Connecting the controller to the PC can be useful (or necessary) in the following situations:
−remote monitoring and recording of current measurement data and process control (outputs status);
−quick configuration of parameters, including copying the settings to other controllers of the same type.
In order to establish a long range communication, set up the connection in the RS485 standard with port available in the
computer (directly or by means of the RS485 converter), according to the description in section 15.

In addition, the controllers as a standard are equipped with PRG ports which allow to connect to the PC via the AR955
programming device (without galvanic isolation, cable length 1.2m). o use both the programming device and the RS485
port, the supplied serial port drivers must be installed on the computer.

baudrate (37: br ) are identical to the settings of computer program. In addition, set in the program options the
number of the COM serial port (for the RS485 converter or AR955 programming device it is the number given by
the operating system during installation of the drivers).

RS485/RS485 amplifiers. ermination resistors when MAS ER
is at the beginning of the line (see fig. above):
- at the beginning of the line: 2 x 820Ω to frame and to +5V of the MAS ER and 150Ω between lines,
- at the end of the line: 150Ω between lines.
ermination resistors when MAS ER is in the middle of the line:
- at the converter: 2 x 820Ω to frame and to +5V of the converter,
- at both ends of the line: 150Ω between lines.
Devices from different manufacturers forming a network 485 (eg converters RS485/USB) may have a built-in
termination resistors, and then there is no need for external components.
