1. APPLICATION
The RE60 controller controls the temperature in objects through
turning on and off the electrical controlling device according to
the defined setting by the controller. It cooperates directly with RTD
and TC.
It is destined for the temperature control in telecommunication
cabinets in food and drying industries and everywhere, where there
is the necessity to stabilize the temperature changes.
The controller has one output destined for the control and two alarm
outputs.

electrical measuring automation instruments acc. to EN 61010-1
standard requirements concerning the resistance against electro-
magnetic noise acc. to EN 61000-6-2 standard and emission
of electromagnetic noise occurring in the industrial environment
acc. to EN 61000-6-4 standard.

one must remember to connect it before the connection of the
instrument to the mains.
- When working on live instruments, the applicable national regulations
for the prevention of accidents must be observed.
- The electrical installation must be carried out according to the
appropriate regulations (cable cross-sections, fuses, PE connection).
Additional information can be obtained from the users manual.
- The documentation contains information about installation in
compliance with EMC (shielding, grounding, filters and cables).
These notes must be observed for all CE-marked products.

responsible for the compliance with the required limit values
demanded by the EMC legislation.
5. Operation
- Measuring systems including RE60 controllers must be equipped
with protection devices according to the corresponding standard
and regulations for prevention of accidents.
- After the instrument has been disconnected from the supply
voltage, live components and power connections must not be
touched immediately because capacitors can be charged.
- The housing must be closed during operation.
6. Maintenance and servicing.
- Please observe the manufacturers documentation and read all
product-specific safety and application notes in this users manual.
- Before taking the meter housing out, one must turn the supply off.
- The removal of the instrument housing during the warranty
contract period may cause its cancellation.
When unpacking the controller, please check whether the type
and version code on the data plate correspond to the order.

3.4. Installation recommendations
In order to obtain a full fastness against electromagnetic noise in
an environment with unknown noise level, it is recommended to
observe 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,
- apply metallic shields in the shape of tubes or braids to conduct
supplying wires,
- 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 as above,
- all shields should be one-side earthed or connected to the protective
wire, the nearest possible to the controller,
- apply the general principle, that wires leading different signals
should be led at the maximal distance between them (no less
than 30 cm), and the crossing of these group of wires made
at right angle (90o).

4. STARTING TO WORK
After connecting the supply, what is signalled by the green diode,
the controller displays the type and program version.
After ca three seconds, the controller transits to the control acc. to
set parameters. The controller displays the measured value, the
set point and annunciators of connected outputs.
The on-off control algorythm with hysteresis 2oC is set by the
manufacturer.
A character message informing about abnormalities can be shown
on the display (tab. 2).
Change of the set point
The entry into the set point change mode follows after pressing the
or push-button. The way to change the set point is shown
on the fig. 5. If the set point is not accepted within 30 seconds from
the last pressure of the or push-button, the controller
transits automatically into the normal working mode without the
introduction of a new set point.

5. PROGRAMMING OF CONTROLLER PARAMETERS
5.1. Diagram of the controller menu
The controller service is presented on the fig.6. after pressing and
holding the push-button during at least 2 seconds, the pro-
gramming of parameters is possible. The transition between para-
meters is carried out by means of and push-buttons.
Some parameters can be invisible - it depends on the choice of the
control algorythm or the alarm configuration. The table 1 includes
the description of parameters. The return to the normal working
mode follows after pressing the push-button or automatically
after 30 seconds from the last push-button pressure.

6. CONTROL
6.1. On-Off control
When a high precision of the temperature control is not required,
especially for objects with a high time-constant and a small delay,
one can apply the on-off control with hysteresis. Advantages of this
control way are the simplicity and reliability, however its defect is
the oscillation formation, even at small hysteresis values.

6.2. PID control
When we want to obtain a better accuracy of the temperature con-
trol, one must apply the PID algorythm. The controller tuning to the
object consists on setting the value of the proportional element,
integrating and differentiating elements, and the output pulse repe-
tition period.
6.2.1. Selection of PID settings by the object
identification method
One must read out the object delay time To and the maximal
temperature accretion speed from the dependence:
Vmax =
Calculate the PID settings acc. to the given equations:
