1. APPLICATION
Controller PCE-RE01 is designed to control temperature. It cooperates
directly with resistance-type sensors Pt100, Pt1000 and NTC.
The controller has one output for on-off control and one output for alarm
signalling. The on-off control employs the PID or on-off algorithm. For the
on-off control, the minimum on and off times for the output may be set.
The control output has a changeover contact and allows for the direct
control of low-power objects.
An innovative SMART PID algorithm is implemented in the controller.
In addition, the controller has a binary input to control the controller’s fun-
ctions and an internal sound signalling device.
2. CONTROLLER SET
The delivered controller set is composed of:
1. controller......................................... 1 piece
4. holding clips ...................................... 4 pieces

3. BASIC REQUIREMENTS, OPERATIONAL
SAFETY
In the safety service scope, the controller meets to requirements of the
EN 61010-1 standard.
Observations Concerning the Operational Safety:
•The assembly and installation of electrical connections shall be
performedbyapersonqualiedfortheassemblyofelectricaldevices.
•Check if the connections are made correctly before powering on the
controller.
•Power off the controller and disconnect measuring circuits before
removing the controller’s housing.
•The removal of the controller’s housing during the validity of the war-
rantyagreementnulliestheagreement.
•The devices is designed for installation and use in industrial, electro-
magnetic environmental conditions.
• Theinstallationshouldbettedwithaswitchorcircuit-breakerlocated
near the device, easily accessible to the operator and with appropriate
marking.
4. INSTALLATION
4.1. Controller Installation
Attach the controller to the board with four screw mounts
in line with Fig. 1. The hole in the board should be 71+0.7 x 29+0.6 mm.
The board material may be up to 15 mm thick.

Fig. 2. Controller dimensions.
The controller’s dimensions are shown on Fig. 2.

4.2. Electrical Connections
The controller has two disconnectable strips with screw terminals.
One strip allows for the connection of power supply and output
with a wire up to 2.5 mm2in size and the other strip for the connection
of input signals with a wire up to 1.5 mm2in size.
Fig. 3. View of the controller’s connection strips.
4.3. Installation recommendations
To obtain full resistance to electromagnetic interference,
observe the following rules:
•do not power the controller from the mains near equipment genera-
ting impulse interference and do not use common earthing circuits
for them,
• uselinelters,
•measuring signal input wires should be screened twisted pairs and
wires for resistance sensor in three-wire systems formed by screened
twisted wires with the same length, size and resistance,
•all the screens should be earthed or connected to a protective cable,
on one side, as close to the controller as possible,
•follow the general principle that wires which transmit different signals
should run as far from each other as possible (no less than 30 cm)
and bundles should cross each other at the angle of 90o.

Description of the controller
Power on
Once powered on, the controller performs a display test, shows re01,
software version and then the measured value.
The display may show a sign message on irregularities (see Table no. 13).
The on-off control algorithm with hysteresis 2.0°C is factory set.
Change of the set point
To display the set point, press or , the dot for the last
digit lights up then. To change the set point, press again or
(Fig.5).Thedotashestosignalthestartofchange.Accept
the new set point with within 30 seconds from the last pressed
or ; otherwise the controller changes over to display
the measured value with the previously set-up set point.

6.1. Programming of controller parameters
Press and hold for approx. 2 seconds to enter
the programming matrix. The programming matrix may be protected
with an access code. If a wrong code is inserted, one may only view
the settings without changing them.
Fig. 7 shows the navigation matrix in the programming mode.
To go from one level to another, use or and to select
a level, use . Once the level is selected or are
used to navigate among parameters. In order to change the parameter
setting, follow point Change of the setting. To exit the selected level,
go from parameter to parameter u til the symbol [. . .] appears
and press . To exit the programming matrix for the normal
operation mode, go from level to level until the symbol [. . .] appears and
press .
Some parameters of the controller may be hidden,
depending on the current conguration. The parameters are
described in Table no. 1. 30 seconds from the last button pressed,
the device returns automatically to the normal operation mode.

the control signal h = 0%, Yfl > 50%, the control signal h = 100%.
11) Function available only for direct control dir - cooling. Manual
or automatic operation of the defrost function will take place only when
the measured PV value is lower than the value that causes the end
of the defrost (Dsp parameter) and the cooling cycle is completed
(i.e. the measured PV value reaches the SP setpoint).
12) Defrosting continues until the PV measured value reaches

will end after the time set by Dtim parameter.

7. CONTROLLER INPUTS AND OUTPUTS
7.1. Measuring Input
The measurement input is a source of the measured value
used in the control or for the alarm. Depending on the design, Pt100,
Pt1000 or NTC sensors may be connected to the input.
First, use the parameter unit to set the displayed temperature unit.
A change of the unit sets factory settings for parameters whose ranges
are different for Celsius and Fahrenheit degrees.
The input signal range is set with the parameter iNty.
An additional parameter is the decimal point position which determines
the display format of the measured and set points. It is set with the para-
meter dp. The measured value indication is adjusted with the parameter
shif. For the Pt100 sensor, one may also set the line resistance with
the parameter r-li.
7.2. Binary input
To set the function of the binary input, use the parameter bNin.
The following functions of the binary input are available:
•no function – the status of the binary input does not affect
the controller’s operation,
•control stop – the control is interrupted, the control output operates
as if the sensor were damaged, the alarm operates independently,
•alarm reset – resetting the alarm memory,
•output control – direct control of inputs (the output status depends
of the input status or may be reversed),
•keyboard lock – push-buttons locked in the normal operation mode.
•defrost – defrost function is switched on
7.3. Outputs
The controller has two outputs. Control may only use output 1. Both
outputs may be used for alarms and control through the binary input.
