1 Important
Ht40B is a temperature / process controller intended for the built-in to panel. he format of controller is 96 x 48 mm
(1/8 DIN).
he scope of the controller:
• controlling of stp value,
• controlling Master – Slave (1 controller is supervisory MAS ER, the others are SLAVEs – receive stp value),
• cascade controlling (it is used in systems with long lag times).
he controller can be equipped with 1 input:
• temperature (thermocouples + rtd sensor -Pt100),
• process (0-20mA, 4-20mA, 0-5V, 1-5V, 0-10V),
3 outputs:
• control (heating control),
• auxiliary (cooling control, signalling),
• alarm,
and communication lines:
• RS-232, protocol MODBUS R U,
• EIA-485, protocol MODBUS R U.
he controller is easy to run and operate. he parameters set can be locked and thus preventing from deleting by a user.

output power that is supplied to system.
At manual operation the user adjusts the required output power.
Manual operation
Manual operation is set by double pressing the key . It must be allowed by setting parameter FKEY = A-M . Parameter FKEY
is found in configuration level, menu SYS .
Important:
• When in manual operation the controller can not influence the output power that is set by a user. he behavior of the
system is then fully under users control.
• When in manual operation, Man blinks on lower display.
• he controller remains in the chosen mode of operation even after the power interruption.
• In manual operation the zero output power is set after the power interruption.
• In manual operation the output power is always set in % (0 to 100 for heating, -100 to 0 for cooling, -100 to 100 for
heating and cooling) and even in the case that the output is configured as the ON/OFF output.

L-r = L )
Procedure of starting autotunning:
• Autotunning you can start with parameter Aut = ht (setting parameters for heating) or Aut = CL (setting parameters
for cooling). Parameter Aut you will find in operation level he control output must be set for PID controlling.
• he controller explores the characteristics of system from switching ON/OFF on the output and determines optimal PID
parameters. It can cause an overshoot.
• In the course of autotunning on lower display the information messages ( Aut1 , Aut2 , Aut3 ) blink.
• After the autotunning is finished the parameters are edited and the information messages stop blinking.
Important:
• Parameters Pb1A , It1A , dE1A , are set when 1 set of PID parameters is used ( ALGo = PId ) or the both sets of PID parameters
are used ( ALGo = 2PId ) and the actual set point value is lower than parameter SPId .
• Parameters Pb1b , It1b , dE1b , are set if the actual set point value is higher than parameter SPId when the both sets of PID
parameters are used ( ALGo = 2PId )
Parameters ALGo and SPId are found in configuration level, menu out1 .

6 1 Measurement
he right selection, the installation, the wiring, the location of sensor in the equipment and the corresponding setting of
parameters of the controller has the essential importance for the correct function. Parameters for the configuration of the
measurement input are in configuration level, menu InP1 .
Setting of input sensor
Set the corresponding input sensor in parameter SEn1 . You will find the survey of input sensors in the chapter Technical
parameters, see page 28.
You can set the position of decimal point by parameter dEC1 . For thermal sensors it is possible to display without decimal point
or with 1 decimal point.
Set the calibration of sensor with the parameter CAL1 . he set value is added to process/measured value.
You can set the limit for set point value in configuration level, menu SYS , parameters SP1L and SP1h .
Important:
• hermocouple and R D inputs have the detection of improperly wired sensor. When the sensor is open or broken, the
control output is turned OFF, the alarm output is activated.
Measuring range of process inputs
In configuration level, menu InP1 , you can define the measuring range of the process inputs with parameters rL 1 , rh 1 and
dEC1 .
Example of setting process input:
You want the input signal 4 to 20 mA to be displayed in the range 6.0 to 24.0.
Set dEC1 = 0.0 , rL 1 = 6.0 a rh 1 = 24.0. he distribution between the values 6.0 and 24.0 will be linear.
6 2 Controlling, the control output
You can select in the controller ON/OFF or PID controlling for heating. If PID controlling is set, you can use the autotuning of
PID parameters, see page 9 and the power limit function, see page 17.
he parameters for configuration of the control output 1 are in configuration level, menu out1 .
ON/OFF controlling
ON/OFF control is selected by setting ot1 = ht2 . It is used for less exacting application. It is not possible to achieve zero
hysteresis value on principle. he process value rises and drops about set point value in the characteristic way.

PID controlling
PID control is selected by setting ot1 = ht . It provides the precise control. For the correct function of the controller,
however, it is necessary to set properly PID parameters. Autotunning for setting of PID parameters is described on page 9.
PID parameters have the following meaning:
• Pb proportional band is set in measured units. It is the band about the set point value in which the controller keeps the
temperature.
• It integral factor, in minutes. Integral factor compensates the loss of system. A low integral value causes a fast
integrating action.
• dE derivative factor, in minutes. Derivative responses to fast changes and tries to react against them. he more value is,
the more derivative factor reacts.
If the control output is 2 state (ON/OFF) (relay or SSR), the power is (given in %) transferred to the output with so called pulse
width modulation. In each time cycle (parameter Ct1 , you will find it in configuration level, menu out1 ) the control output is
switched ON once and once OFF. he more the power is necessary, the wider the width of switching is. he output responses
are illustrated in the third part of the drawing.

You can improve the quality of control by limiting of the output power.

is 30%. he output is ON for 3 seconds and
OFF for 7 seconds.
• ime cycle is 10 seconds, the power requested
is 5%. he output is ON for 0,5 second and
OFF for 9,5 seconds.
Important:
• he duration of time cycle has the influence on
the quality of control. he longer the cycle is,
the less the quality of control is.
• If the electromechanical unit (relay, switching
contactor) is used for the control output, the
duration of time cycle must be set longer with
regard to lifetime of switch.

Example how to use the power limit
function:
When rising at set point value the big overshoot occurs.
One of possible solution is the power limit in the vicinity
of set point value. he procedure is the following:
• Find out the power supplied to the stable system.
• Set the switcher S PL on the value by several
o
C less
than set point value.
• Set power limit PLLo to 100%.
• Set power limit PLhI approx. by 10 to 20% higher
than the power supplied to the stable system.

6 3 Alarm
he third output (output 3) is alarm.
he configuration parameters of the output you will find in configuration level, menu out3 , setting of the alarm limits ALLo and
ALhI you will find in operation level or user level.
Setting of alarm output
Set this function with parameter out3 :
• ot3 = oFF , alarm output is turned OFF.
• ot3 = ALPr , alarm limits defined by the absolute value.
• ot3 = ALdE , alarm limits are set as the deviation from stp value SP1.
Important:
• Relay in standby MODE means active alarm.
• When controller is switched OFF, error of sensor, error of controller the alarm is active.
Alarm defined by the absolute value of temperature ot3 = ALPr
Alarm defined by the deviation from stp value ot3 = ALdE
Temporary, permanent(latched) alarm
Alarm can be temporary ( LAt3 = oFF ) or permanent ( LAt3 = on ).
• emporary alarm will turn automatically off when the alarm condition is over.
• Permanent alarm is turned ON even when the alarm condition is over. urn OFF permanent (latched) alarm when the alarm
condition is over by the function AoFF , that is found in user level or operation level. Permanent alarm is also turned off
after the supply voltage interruption.

Silencing of alarm
Active sides of alarm
With parameter SId3 you can choose the active side of alarm:
• SId3 = both , both sides (limits) are active.
• SId3 = hI , only high alarm side (limit) is active.
• SId3 = Lo , only low alarm side (limit) is active.
6 4 System Master – Slave
If the controller is equipped with communication line (EIA-485), it can be set up as MAS ER as well as SLAVE in system
Master – Slave, ie. in system when 1 controller transmits stp value and the other controllers receive this stp value. Slave
controllers can modify this value by difference, parameter dIF .

When power
up alarm is
deactivated
Silencing of alarm can be used to disable
alarm at startup rising to set point value. his
state should not be evaluated as error because
the system is not yet stable. his function is
set with the parameter:
• SIL3 = oFF , function is not active
• SIL3 = on , alarm can be activated
after the process value at startup rising
reached the allowed range for the first
time (between alarm limits ).

Setting of the controller – Master
• In configuration level, menu CoMM , set parameter CoMM = SGnL .
• In operation level, parameter is set L-r = L .
Setting of the controller - Slave
• In configuration level, menu CoMM , set parameter CoMM = Mod , setting of the parameters Addr can remain unchanged.
• In operation level, set parameter L-r = M-S .
• he response to communication error in the reception of stp value you can set in configuration level, menu SYS ,
parameters rtI and rErr .
• he communication error in the reception of stp value can be indicated with the output 2, by setting ot2 = rSP .
If the controller does not receive stp value from communication line, the output 2 will be switched ON.
6 5 Cascade controlling
Cascade controlling is used for system with long lag times, i.e. in systems where the response to the turn ON of action unit is
too (e.g. in muffle furnace, ..). By configuration of 2 controllers as a cascade system you achieve that long lag time will be
divided into 2 parts and thus you improve the quality of control.
Setting of outer-loop controller
• In configuration level, menu CoMM , set parameter CoMM = SGnL .
• In operation level you have to set parameter L-r = L .
Setting of inner-loop controller
• In configuration level, menu CoMM , set parameter CoMM = Mod , setting of parameter Addr can remain unchanged.
• In operation level set parameter L-r = CSCd .
• In operation level set with the parameters CdLo a CdhI the temperature range in which the inner-loop controller will control.
• Error in communication connection of controllers you can indicate with output 2, set ot2 = rSP . If the controller does not
receive the information from communication line, the output 2 will be switched ON.
