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.

4.2. 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 mm2,
the second strip enables input signal connections by a wire of 1,5 mm2.

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.

Switching a supply on
After powering on, the controller performs the display test, displays re70
text, software version and the measured value.
Display may also show an error message (see table 11).
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.
