1 Important
Ht40B is a temperature / process controller intended for the built-in to panel. The format of controller is 96 x 48 mm
(1/8 DIN).
The scope of the controller:
• controlling of stp value,
• controlling Master – Slave (1 controller is supervisory MASTER, the others are SLAVEs – receive stp value),
• cascade controlling (it is used in systems with long lag times).
The 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 RTU,
• EIA-485, protocol MODBUS RTU.
The controller is easy to run and operate. The parameters set can be locked and thus preventing from deleting by a user.
User manual for the controller Ht40B is divided into the particular chapters. When you install and put it into operation we
recommend proceeding in the following way:

6.1 Measurement
The 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
. The 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:
• Thermocouple and RTD 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. The 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.
The 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. The 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. The 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. The more the power is necessary, the wider the width of switching is. The output responses
are illustrated in the third part of the drawing.

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

Example of pulse width modulation of

OFF for 7 seconds.
• Time cycle is 10 seconds, the power requested
is 5%. The output is ON for 0,5 second and
OFF for 9,5 seconds.
Important:
• The duration of time cycle has the influence on
the quality of control. The 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.

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. The procedure is the following:
• Find out the power supplied to the stable system.
• Set the switcher
S PL
on the value by several oC less
than set point value.
• Set power limit
PLLo
to 100%.
• Set power limit

approx. by 10 to 20% higher
than the power supplied to the stable system.

6.3 Alarm
The third output (output 3) is alarm.
The configuration parameters of the output you will find in configuration level, menu
out3
, setting of the alarm limits

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
).
• Temporary alarm will turn automatically off when the alarm condition is over.
• Permanent alarm is turned ON even when the alarm condition is over. Turn 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.

6.4 System Master – Slave
If the controller is equipped with communication line (EIA-485), it can be set up as MASTER 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

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.

9 Installation
The controller is designed to be mounted to the panel cutout. Slide the controller into the cutout and fix it with 2 flanges that are
supplied with the controller. The installation requires the access to the back of the panel.
Mounting dimmensions
• Width x height x overall length: 48 x 96 x 121 mm (including terminal board).
• Behind panel length: 114 mm ((including terminal board).
• Cutout in the panel: 44 x 91 mm.
• The thickness of panel: 1,5 to 10 mm.
Mounting
• Make the panel cutout 44 x 91 mm.
• Slide the controller into the panel cutout.
• Insert the flanges for holding into the holes upward and downward or on both sides of the controller.
• Tighten the screws firmly on the flanges.
The controller is now installed, before wiring we recommend to read thoroughly the chapter on the possible sources of
interference and principals for installation.
Wiring of the controller begins on page 24.
9.1 Principals for installation, the sources of interference
There are many possible sources of interference in environment of the controller. Among the most harmful sources of
interference are the following:
• Equipment with inductive load, e.g. electromotors, winding of relays and breakers, … .
• Thyristors and other semiconductor equipment
• Welding devices.
• Wires carrying high currents.
• Fluorescent lightings and neon lights.
9.2 Reduction of influence of interference
Making a design of system, try to observe these guidelines:
• All wires of power supply voltage and power wires carrying high currents must be lead separately from signal leads (e.g.
thermocouple lead wire, communication lines). Minimum distance between these types of wires should not be smaller than
30 cm.
• If signal and power wires cross each other it is suitable for them to be crossed in right angle.
• From the beginning try to find the possible sources of interference and keep the wires away from them.
• Do not install relays and breakers very close to the controller.
• Do not use supply voltage for the controller also for supplying inductive and phase angle control equipment.
• Twisted and shielded wires should be used for signal leads. Shielding should be earthed several times.
When necessary the uninterruptible power sources (UPS) could be used.
24
10 Wiring
To avoid potential electric shock, use safety practices laid down by national standards when wiring and connecting this
unit to a power source. Failure to do so could result in such damage, and / or injury. The wiring must be done only by
the authorized person.
If there is any default of the device could cause damage, the equipment with the controller must be fitted with the
independent protection unit (thermal cut-out).
Supply voltage
Before you connect the unit to a supply power source, check the level of supply voltage.
The controller is intended for use in industrial or in laboratory equipment.

11 Putting into operation
The initial set-up can be done only by the qualified and authorized person. The wrong set-up can cause serious damage.
When you power the controller up for the first time, you must enter the most necessary data to the controller for its problemfree operation:
• Type of sensor, position of decimal point
• Operational range of set point value
• Set-up for the control output
11.1 Guidelines
Let`s suppose that the controller is installed in the panel and you have just power it up for the first time. Parameters of initial
operation are the following:
•
