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.

RE70-09-R1 User's Manual 4
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. Installation
4.1. Controller installation
Fix the controller to the board with four screw brackets as shown
in the fig. 1. A slot in the panel must have the dimensions 45+0,6 x 45+0,6 mm.
The thickness of the panel material cannot exceed 15 mm.

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,

RE70-09-R1 User's Manual 6
─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,
─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.
Start by using a 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 parameter.
For the Pt100 thermoresistor, choose the t-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 parameter.
Correction of the indicated measured value is determined by the 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
8.1. 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.
Fig. 13. Operation way of the heating type output for the ON-OFF control.
8.2. 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.
8.2.1. 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 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 is hidden.
For a correct realization of the self-tuning function, it is required to set the
parameters sTlo and sTHi. The parameter sTlo 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 sTHi should

RE70-09-R1 User's Manual 14
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.
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 sTlo, sTHi.
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.

RE70-09-R1 User's Manual 15
8.2.2. 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.
9. Alarms
The controller output can be configured as an alarm output. For this, set the
parameter out as one of alarms. Available types of alarms are given on the
figure 14.

the parameter aLdu. Alarm hysteresis, the zone around the set point in which
the input state is not changed is defined by the aLHy parameter.

12. Error signaling
Character messages signaling the incorrect controller operation. Table 11
Error code Reason Procedure
____
Down overflow of the
range limit or lack of RTD
Check, if input signal values are situated in the
appropriate range – if yes, check if check if there is
no short circuit in the thermoresistor or the
thermocouple is connected inversely.
::::
Upper overflow of the
range limit or break in the
sensor circuit
Check, if input signal values are situated in the
appropriate range – if yes, check if there is no break
in the sensor circuit.
eRad
Input discalibrated Connect the controller supply again and if that is not
effective, contact the nearest service shop.
eRee
Configuration parameters
checksum error
Connect the controller supply again and if that is not
effective, contact the nearest service shop.
