• Difference from the previous version of the software :
0.1s format is added in timer modes.
The controller has 5 outputs / three discrete and two analog /
•Discrete outputs K1 and K2 are control outputs of temperature
controllers.
•The discrete output K3 output is programmed as a timer or alarm in the
System Parameters section
•Analog outputs are retransmitting input variables.
Timer has 2 main modes:
•as an independent from input variables. In this mode the timer is started
by front ;
•depending on whether the measured parameter has reached the
controller setting.In this mode, the timer starts and works until at the
control input has a active level.
Each of the main modes has two sub-modes of work which define timer output:
•The output is switched on during counting
•Output is activated after the expiry of the count.

4. OPERATION
Display Basic parameters used in the device:
SP Set Point
Zоn Zone proportional zone or hysteresis in ON/OFF control
PV Process variable input parameter
Ahi Alarm Hi upper alarm limit
ALО Alarm Lo lower alarm limit
In operational mode, the upper display shows the value of Channel 1, while the
lower display shows the value of Channel 2. Green LED s indicate whether the
corresponding output is active, respectively, the top for Channel 1 and the bottom for
Channel 2.
4.1. TEMPERATURE CONTROLLER SET TINGS
To access programming mode, press and hold the SET button for more than 5 seconds (while
the button is pressed, the display shows the values of the two set points. If the button is
released before the time expires, the entry into the mode does not take place).
In programming mode, the lower display displays the parameter name and the upper
display its value. Editing the values is done with the DOWN and UP buttons, and passing
on to the next parameter with the SET button.
Name Description Values
SP 1 Channel 1 Set point Within the range of change
of the input parameter
SP 2 Channel 2 Set point Within the range of change
of the input parameter
4.2. ALARM OUTPUT
Permitted by the SrEG parameter from the Hidden System Parameters section.
When the value of PV for some channel goes over (falls below) the upper (lower) alarm
limit, it is triggered and "ALL" message appears periodically on the channel display.
The alarm output is common to both channels and it is triggered regardless of
which channel is in an alarm situation. On the corresponding display alternating "ALL" and
the measured value are displayed.

4.3. TIMER - MODES OF OPERATION
Permitted by the SrEG parameter from the Hidden System Parameters section.
The timer section can work independently of the rest of the controller (from the
measured value) by starting / stopping with buttons or on the pulse front at the "Start timer"
input or it works depending on the measured value as the timer starts when the assigned
value is reached(selected by the SrEG parameter).
●MODE 1 - The timer works independently of the controller
Starting from digital input Start timer / start on front /
A button is used to manually start.
MODE 1.1: The timer is started by activating the GND level at the Start timer input
( pressing an external button,for example), with which the timer output is activated and
begins to decrease the set time. The timer output is active until the time has elapsed or the
external button is pressed again.
The red LED blinks until the time has elapsed.
MODE 1. 2 : ТThe timer is started by pressing an external button. The red LED flashes
until the set time elapses. After that, the output activates (indicated by a permanently
illuminated red LED) and remains active until pressing the external button or by a power
failure.
●MODE 2 - The timer starts depending on whether the measured value (PV) has
reached the controller (SP) setting .
The Start timer input must have a GND-level enable.
A switch is used for manual permission.
MODE 2 .1: The timer starts when the starting conditions are reached and an active
level at Start timer (permission from an external switch), which activates the timer output
and the set time starts to count down. The timer output is active until the time elapses or until
disabled by the external key. The red LED flashes until the time runs out. A new start is only
possible afterwards prohibition and re authorization by the external switch.
MODE 2 . 2 : The timer starts when the starting conditions are reached and an active
level at Start timer (permission from an external switch). The red LED flashes until the set
time elapses. After that, the output activates (indicated by a permanently illuminated red
LED) and remains active until disabled by the external key or by a power failure. A new start
is only possible afterwards prohibition and re authorization by the external switch .
In the above two modes, when feeding the supply voltage, if enabled from the external switch
and the startup conditions are present, the timer restarts!

6. ANALOG INPUTS CONNECTIONS
For the sake of good functioning, it's important that the probes are located on a
suitable place in the environment, in which the temperature regulation will take place.
6.1 Resistive sensors connection (Pt100 or others)
The sensors can be connected via a two wire or three wire line. The connection of
two wire sensors to a three wire line follows the diagram shown in FIG. 6, while between
terminals 1 and 2 and terminals 5 and 6 of the controller, cable bridges are placed (short
circuited).
At longer distances between sensor and controller, it's recommended to use a three
wire line because it compensates the measurement error of the temperature due to the
additional resistance introduced by the connecting wires. Connecting three wire sensors to
the controller is done according to the scheme shown on FIG. 2 as to terminals 1 and 2 and
terminals 5 and 6 of the controller connect the cables connected to the short circuit in the
sensor.
Figure 1 Figure 2
6.2 Thermocouple connection
When connecting a sensor type thermocouple, care must be taken about the polarity
of the sensor. If polarity is inverthed, the device's readings will be incorrect.
When working with thermocouples, it is necessary to use a compensation cable,
corresponding to the type of thermocouple used (Figure 3).

9. SYSTEM PARAMETERS
The system parameter programming mode is accessed by pressing buttons UP and DOWN
simultaneously for more than 5 seconds.
In the mode, the parameter's name is shown on the lower display. With buttons DOWN
and UP the desired parameter is selected, and with SET button, on the upper display, the
parameter's value is displayed.
Editing the values is done with the DOWN and UP buttons and the switching to the next
parameter with the SET button.

10. CONSUMER SETTING OF OFFSET ON ANALOG CHANNELS
In this mode, users can freely enter a programmable value, which will always be added to
the measurement ("offset"). This is used when there's a discrepancy between the value
displayed by the device and measured with another reference instrument.
To authorize the user offset of the readings of both channels, it is necessary to power on
the device while the DOWN button is pressed.
In this case, values are added (subtracted when with minus sign) to channel readings.
Assigning each separate offset is done the way, as is setting the setpoint SP of each
channel in normal work mode.
Caution – the device does not display previously made changes!
Changing with extreme caution can lead to incorrect operation of the unit!
Offset mode is available only until the next shut down.
11. RECOMMENDATION AGAINST EMI (Electromagnetic Interference)
•Recommendations for use of connecting wires
- Wires that carry a similar type of signals can be packed together, but if the signals
are different, the wires must be separated to prevent electromagnetic interaction.
When there have to be crossed wires with different signal types this must be done at
an angle of 90 degrees and a long distance.
Wires, which carry weak signals and wires connecting the sensors to the controller
must not be near contactors, motors, generators, radios and wires, which carry large currents.
•Noise suppression using the built-in in the controller filter
If the input parameter fluctuates and is not stable it is necessary to reduce the filter
coefficient Fr 1 or Fr2. As lower the value, the heavier the filter and slowly change the input
parameter.
If the process variable on the display jumps periodically for short intervals, it is
necessary to increase the parameter tJ 1 ot tJ2. When increasing this parameter, the device
reacts slower at an unexpected “jump’’ in the input, but ignores the short term interference.

12. HIDDEN SYSTEM PARAMETERS
USED ONLY BY SERVICE SPECIALIST
WRONG SETTINGS MAY LEAD TO THE INCORRECT FUNCTION OF THE DEVICE
Hidden system parameters are “visible’’ only until the next shut down.
To access hidden system parameters, it’s needed to feed the power supply while holding
and pressing the UP button. In this case, in the list of system parameters, after End, the
following ones appear:
Name Description Values
Fr 1 Filter coefficient for Channel 1
0 128 units
A lower value corresponds to a
“heavier” filter of the input variable
tJ 1 Waiting time before a filter jump for
Channel 1 0 128 seconds
JP 1 Filter rebound threshold of Channel 1
0 .. 255 units of input
When changing the input variable to a
value greater than the preset and
maintaining the new state for a time
greater than tJ 1, the filter bounces
and takes the new value directly.
Fr 2 Filter coefficient for Channel 2
0 128 units
A lower value corresponds to a
“heavier” filter of the input variable
tJ 2
Waiting time before a filter jump for
Channel 2 when changing the input
variable with a value greater than JP 2.
0 128 seconds
JP 2 Filter rebound threshold of Channel 2
0 .. 255 units of input
When changing the input variable
to a value greater than the preset and
maintaining the new state for a time
greater than tJ 2, the filter bounces
and takes the new value directly.
