1. Application
The RE70 controller is destined for the temperature control. Controller works directly with
the resistance sensors or thermoelectric sensors.
The controller is equipped with one output that allows for dual-point control and alert
signalization. Dual-point control is based on the PID or ON/OFF algorithm. Relay output is
equipped with a switchable contact and allows for indirect control of the low-power objects.
The innovative SMART PID algorithm has been implemented in the controller.

3. Basic requirements, operational safety
In terms of operational safety the controller meets the requirements of the EN 61010-1
standard.
Comments concerning safety:
•Assembly and installation of the electrical connections should conducted only by
people authorised to perform assembly of electric devices.
•Always check the state of connections before turning the controller on.
•Prior to taking the controller housing off, always turn the supply off and disconnect
measuring circuits.
•Removal of the controller housing during the warranty period voids the warranty.
•The device is designed to installation and usage in the industrial electromagnetic
environment.
•The installation should have a switch or a circuit-breaker installed. This switch should
be located near the device, easy accessible by the operator and suitably marked.

4.3. Recommendations for installation
To achieve full electromagnetic resistance of the controller, it is necessary to follow the
rules described below:
do not supply the controller from the network in the proximity of devices generating
high pulse noises and do not apply common earthing circuits,
apply network filters,
wires leading measuring signals should be twisted in pairs, and for resistance
sensors in 3-wire connection, twisted of wires of the same length, cross-section and
resistance, and led in a shield,
all shields should be one-side earthed or connected to the protection wire, the
nearest possible to the controller,

RE70-09 User's Manual 6
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°.

7. Inputs and outputs of the controller
7.1. Inputs
Input is the source of the measured value used for control or for alarms. The input is
universal and the sensors Pt100, Pt1000 or thermocouples can be connected to it.

RE70-09 User's Manual 11
Start by using a unit
unitunit
unit parameter to set the temperature display unit. Unit change
resets the value to the factory settings, with a different value ranges for Celsius and
Fahrenheit scale.
Input signal is selected with a iNty

iNty parameter.
For the Pt100 thermoresistor, choose the t

lili
li connection type - 2-wire or 3-wire. In
the 3-wire Pt100 connection, resistance compensation is automatic.
For thermocouples, a cold terminal compensation is automatic.
Position of the decimal point is a additional parameter that determines display format of
measured value and set point; it is set by the dp
dpdp
dp parameter. Correction of the indicated
measured value is determined by the shif
shifshif
shif parameter.
7.1. Output
The controller has one output. It is possible to choose the following output options: on-off
control, proportional control (PID) or alert. It is necessary to set the pulse period for the
proportional control.
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
7.1. ON-OFF algorithm
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.
Disadvantage of this method is the occurrence of oscillations, even at small hysteresis
values.

7.2. Innovative SMART PID algorithm
When high precision of the temperature control is necessary, it is recommended to use
PID algorithm. Innovative SMART PID algorithm ensures increased precision in the
extended range of the control object classes.
Tuning of the controller to object is achieved by automatically selected PID parameters
using the self-tuning function or manual setting the value of the proportional element, integral
element and derivative element.
7.2.1. Self-tuning
The controller has the function to select PID settings. In most cases these settings
ensure an optimal control.
To begin the self-tuning, transit to the tune
tunetune
tune message (acc. to the fig. 10) and hold down
the button @ during at least 2 sec. If the control algorithm is set on ON-OFF or the self-
tuning function is locked, then the tune message tune
tunetune
tune is hidden.
For a correct realization of the self-tuning function, it is required to set the parameters
s lo
s los lo
s lo and s Hi
s His Hi
s Hi. The parameter s lo
s los lo
s lo should be set on the value corresponding to the
measured value at the switched off control. For object temperature control, you can set 0ºC.
The parameter s Hi
s His Hi
s Hi should be set on the value corresponding to the maximum measured
value when the control is switched on the full power.
The flickering AT symbol informs about the activity of the self-tuning function. The
duration of self-tuning depends on dynamic object properties and can last maximally 10
hours. During self-tuning or directly after it, over-regulations can occur and because of this,
one must set a smaller set point if possible.
The self-tuning is composed of following stages:
self-tuning process
- calculation of PID settings and stored
them in the non-volatile memory
- start control with new PID settings
- enter to manual mode
- the error code is on the display until
confirmation
self-tuning
ended
with success
YES
NO
The self-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 self-tuning experiment does not end with success, then an error code will be displayed,
acc. to the table 4.

RE70-09 User's Manual 13
Error codes for self-tuning function Table 4
Error code Reason Procedure
eS01 P or PD control was selected. One must choose PI, PID control, i.e. the TI unit
must be higher than zero.
eS02 The set point is incorrect. Change temperature set point or the
parameters s lo, s Hi.
eS03 The button @ was pressed.
eS04 The maximal self-tuning duration time has
been exceeded. Check, if the temperature sensor is correctly
situated, if the set point value is not set too
higher for the given object.
eS05 The waiting time of switching has been
exceeded.
eS06 The input range limit has been exceeded. Take note of the way to connect the sensor. Do
not allow that the overflow results in exceeding
of the input range limit.
eS20 Very non-linear object, enabling to obtain
correct values of PID parameters, or an
interference has occurred.
Carry out the self-tuning again. If that does not
help, choose PID parameters manually.
7.2.2. Proceeding in case of a 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) Free jump response:
−decrease the proportional band,
−decrease the integral and derivative time.
b) Over-regulations
−increase the proportional band,
−increase the derivative time,
c) Oscillations
−increase the proportional band,
−increase integral time,
−decrease the derivative time,
d) Instability
−increase the integral time.
