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. 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.

4.2. Electrical connections
The controller has two separate connectors with screw terminals. One strip enables the
connection of the supply and outputs by a wire of 2,5 mm
2
, the second strip enables input
signal connections by a wire of 1,5 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,
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°.

The ON-OFF control algorithm with hysteresis given in the table 2 is set by the defaults.
Change of the set point
Set point is displayed after ? or > buttons are pressed, this is accompanied by SP
diode switching on. To change the set point, press ? or > buttons again (fig. 9). The
beginning of the change is signaled by pulsing dot symbol on the display. New set point must
be accepted with a @ button within 30 seconds after the ? or > button have been
pressed, otherwise regulator will display set point with previously set point.

6.1. Programming Controller Parameters
Pressing and holding down during ca 2 seconds the button @ causes the entry to the
programming matrix. The programming matrix can be protected by an access code. In case
when giving a wrong value of the code, it is only possible to see settings through - without
possibility of changes.
Fig. 11 presents the transition matrix in the programming mode. The transition between
levels is carrying out by using the buttons ? or > and the level selection by using the
button @ . After selecting the level, the transition between parameters is carried out by
using the buttons ? or > . In order to change the parameter setting proceed acc. to the
section 6.3. In order to exit from the selected level, transit between parameters until appears
the symbol [. . .] and press the button @ . In order to exit from the programming matrix to
the normal working mode, transit between levels until appears the symbol [. . .] and press the
button @ .
Some controller parameters can be invisible – it depends on the current configuration.
The description of parameters shows the table 1. The return to the normal working mode
follows automatically after 30 seconds since the last button pressure.

6.3. Setting Change
The change of parameter setting begins after pressing the button @ during the display
of the parameter name. The setting selection is carried out through the buttons ? and >
and accepted by the button @ . The change cancellation follows after the simultaneous
pressure of the buttons ? and > or after 30 seconds since the last button pressure. The
way to change the setting is shown on the fig. 12.

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.
