1. APPLICATION
The RE62 controller is destined to control the temperature and other physical quantities (pressure, humidity, level, etc.) in plastics, food, dehydration industries and other where there is a need to stabilize the changes of the measured value. The measuring input is universal for the thermoresistors, thermocouples or standard linear signals.
The controller allows dual-point control based on the PID or ON/OFF algorithm and alert signalization. The controller can be equipped with the relay outputs, continuous output and 24 V DC power output depending on the version.
The innovative SMART PID algorithm has been implemented in the controller.
All values and the configuration parameters of the controller are available via an optional RS485 communication interface.
The output signals are galvanically isolated from the input signals and power supply.

4.3. Installation Recommendations
In order to obtain full noise immunity of the controller, it is recommended to observe the following principles:
do not supply the controller from the network, in the proximity of devices generating high pulse noise and do not apply common earthing circuits,
apply network filters, wires leading measuring signal should be twisted in pairs and for
the resistance sensors in the 3-wire connection they should use twisted wires of exactly the same length, diameter and resistivity protected by shielding, all shields should be one-side earthed or connected to the protection wire, the nearest possible to the controller, as a rule of thumb, wires transmitting different signals should be spaced as far as it is possible (at least 30 cm) and should be crossed only at the right angle of 90°.

The individual characteristic enables the conversion of the measuring value to the displayed value. It is used to visualize the measurements of non-electrical quantities using the non-electrical transducers of the standard quantities. A conversion is done by approximation with a straight line through the points which are the characteristic parameters (Figure 9).

7. INPUTS AND OUTPUTS OF THE CONTROLLER
7.1 Measuring inputs
Measuring input is the source of the measuring value used for control and alarms.
Measuring input is a universal input capable of accommodating various sensors or standard signals. Input signal is selected with a TYPE parameter in INPUT menu. Position of the decimal point that determines measuring value and set point is set through the DOT POINT parameter. The individual characteristics can be set for the linear inputs (USER CHAR.X1.Y2 parameters) to convert the value of the measuring signal to the measuring value according to the user’s needs (Fig. 9). Correction of the indicated measuring value is done through the COMPENSATION parameter.
7.2 Outputs
The controller has a maximum of three outputs. Each of them can be set for control or alarm.
For the proportional control (with the exception of the analog outputs) a pulse period is also set. Pulse period is a time between two subsequent input engagements during proportional control. Pulse period length should be adjusted for the dynamic properties of the object and characteristics of the output device. It is recommended to use SSR transmitter for quick processes. Relay output is used for a contactor control in the slow-changing processes. Long pulse periods for quick-change processes may cause unnecessary oscillation. In theory, the shorter pulse period is, the better the control, however for the relay output a period should be as large, as possible to optimize lifespan of the relay.

8. CONTROL
8.1 ON-OFF control When high accuracy of a temperature control is not required,
especially for the high time constant and small delay, it is possible to use ON-OFF control with hysteresis. The advantages of this method of control are simplicity and reliability. Disadvantage, however, are the oscillations even at low hysteresis values.

8.2 SMART PID algorithm
When high precision of the temperature control is necessary, it is recommended to use PID algorithm. SMART PID algorithm used, ensures increased precision in the extended range of the control object classes.
Tuning of the controller to object is achieved by manual setting of the proportional term, derivation term or difference term or automatically by auto-tuning function.
8.2.1 Auto-tuning
The controller has the function to select PID settings. These settings ensure the optimal control in most cases.
To begin the auto-tuning, move to the auto-tuning message
RE62-09C-R1
22
User’s manual
(acc. to the Fig. 7) and hold down the button
for at least 2
seconds. If the control algorithm is set to ON-OFF or the auto-tuning function is locked, then the auto-tuning message is hidden. For a correct realization of the auto-tuning function, it is required to set the parameters SELFTUNE MIN and SELFTUNE MAX. The parameter SELFTUNE MIN should be set to the value corresponding to the measuring value at the control switched off. For object temperature control, you can set 0 ºC. The parameter SELFTUNE MAX should be set on the value corresponding to the maximum measuring value when the control is switched on the full power.
The duration of auto-tuning depends on dynamic object properties and can last maximally 10 hours. During auto-tuning or directly after it, over-regulations can occur and because of this set a smaller set point if possible.
The auto-tuning is composed of following stages:
auto-tuning process
– calculation of PID settings and storage them in the non-volatile memory – start of the PID control with new settings
auto-tuning successfully completed
– transition to the manual working mode – displaying an error code which needs to be confirmed
The auto-tuning process will be stopped without counting PID settings, if a supply decay occurs or the button will be pressed .
In this case, the control with current PID settings will be started. If the auto-tuning does not end with success, then an error code
will be displayed acc. to the Table 4.

8.2.2 Proceeding in case of an unsatisfactory PID control It is recommended to choose PID parameters, changing the
value in a twice higher or twice less. During the change, one must respect following principles. a) oscillations
– increase the proportional band – increase the integral time – decrease the derivative time b) over-regulations – increase the proportional band – increase the integral time – increase the derivative time c) instability – decrease the proportional band – decrease the derivative time

can be changed or disabled by the parameter MENU TIMEOUT.
10.2 Manual control
The entry to the manual control mode follows after holding the
button down
during the control signal display. The controller
interrupts the automatic control and begins the manual control of the
output. The buttons
and are used for changing the control
signal. The exit to the normal work mode follows after pressing the
button
.
10.3 Signal retransmission
Continuous output may be used for retransmission of the selected value, e.g. for registering object temperature or copying set point in multi-zone furnaces.
Signal retransmission is possible if the output 1 is a continuous type of output. Start a retransmission configuration by setting the parameter FUNCTION 1 to RETR. Additionally, it is necessary to set upper and lower limit of the signal to be retransmitted (LOW THRESHOLD and UP THRESHOLD). Selection of the signal to be retransmitted is done by the parameter FUNCTION in RETRANSMIT. menu. It is possible to manually set the signal on the continuous output by entering the values in MANUAL VALUE menu.

10.4 Digital filter
You can change the time constant of the digital filter if the measuring value is unstable. When using this feature, use the lowest filter time constant value that allows for the stable measuring value. When the time constant is too high, it may cause the control to become unstable. The time constant may be set from 0.5 to 20 seconds.
10.5 User unit (optional) RE62 controller can display the unit of the measuring value
defined by the user. eCon software should be used to edit and save the unit. The unit can be saved via the optional communication interface RS-485.
The image of the measuring value units uses 18×24 points of a display. This area is divided into 3 lines and each line on the 18 vertical lines with 8 points. One byte of data corresponds to each line, in which the value of 1 in a given field corresponds to turning on a given point on the display, the value 0 – turning off a given point on the display. The definition of the entire image creates a string of 54 bytes stored in 16-bit registers from the address 4500 of the controller. The 8-bit values of the lines in the 16-bit registers are arranged as shown in Figure 11.

10.6. Default settings
Factory settings can be restored by pressing and holding the , buttons within 1 second after switching the power on. Once the start logo appears, the buttons should be released. Restoring factory settings will be confirmed with an appropriate message (SET DEFAULT).
10.7. Detection of sensor failure
In the event of sensor failure manifesting itself in exceeding the lower or upper measuring range (shorting or opening of the measuring line), it is possible to react accordingly to the alarm output. To do this, set the SENSOR ERROR value as a function of the corresponding controller output. When a failure occurs, the selected output will be activated and the alarm icon will be visible on the display. After the failure ceases, the selected output will be released, and the icon signaling the alarm, depending on the option of alarm memory, will be turned off or will flash until the alarm is manually reset.
