1.7 Disposal
Dispose of the product properly when it is no longer usable: pyrometers include electrical and electronic
waste and have to be recycled or disposed environmentally friendly or to send to the manufacturer for
disposal.
1.8 Intended Use
The Regulus RD is a programmable PID temperature controller in table housing. It is optimized for use
with one or two Sensortherm pyrometers as temperature sensor. A second pyrometer can be used for a
second measurement point or to enlarge the overall temperature range when using 2 different ranges.
Types RDS and RDK are additionally equipped with a connection of a thermocouple probe type S or K
(Pt10Rh-Pt, temperature range 0-1750°C or NiCr-Ni, temperature range 0-1300°C), types RDSK, RDKK
or RDSS with 2 thermocouples. Selecting a pyrometer and a temperature probe with different tempera-
ture ranges enables e.g. operation of temperature recording with a pyrometer after temperature probe
recording. This enables a temperature control with a very long temperature range.
Operating the Regulus with a temperature sensor of other manufacturers is only possible via the analog
4-20 mA input.
1.9 Scope of Delivery
Regulus program controller in table housing
4 plug connectors for sensors and electrical connections, inputs/outputs and 2 for relays contacts, 1

2 Safety
2.1 General
Any person who is tasked to carry out work with the device must have read and understood the operat-
ing instructions before beginning. Operation and maintenance of the system may only be performed by
trained personnel.
2.2 Electrical Connection
When connecting or when working on the mains voltage, the general safety guidelines are observed,
e.g. when connecting power transformers. Supply voltage can be lethal when touching. Improper instal-
lation can cause serious injury or physical damage. Only qualified personnel are allowed to work with
mains voltage.
2.3 Use of a Pyrometer with Laser Targeting Light
For easy alignment, the pyrometers may be equipped with a laser targeting light, laser class 2 (accord-
ing to IEC 60825-1-3-4) and has a sticker shown on the right. The laser emits a visible red light with a
maximum power of < 1 mW and a wavelength around 650 nm.
Safety precautions:
Never look into the direct or reflected laser beam.
Do not point the laser to anyone.
If laser radiation hits the eye, the eyes must be intentional-
ly closed and the head immediately moved out of the
beam.
2.4 Secure start / Enable Front Panel Start
In factory settings the device is set to secure start (“Enable front panel start”). This means the “controller
start” function of the Regulus can only be activated if an additional push button (must also be connect-
ed) is pressed. The function is helpful to prevent an accidentally controller start after changing a setting.
The button has to be connected to one of the digital inputs and activated via software menu (digital in-
puts). Deactivation is possible but not recommended (see 3.1 Pin Assignment).
2.5 Responsibility of the Operators
If the device is used in the commercial sector the operator is subject to the legal responsibilities for
workplace safety.
In addition to the safety instructions in this manual follow the regulations of safety, accident prevention
and environmental protection.

accidentally start of the controller due to an additional push button which has to be pressed to-
gether with the “Start” button on the controller. A permanent connection of +24 V (pin 31 or 44)
to the desired output deactivates the function (on your own risk, not recommended).

3.1.1 Thermocouple Types -K and -S
Please consider the special characteristics of thermocouples if the device is equipped with correspond-
ing connectors. Thermocouple probes are sensitive against temperature variation. Using a Regulus and
a thermocouple with different device temperatures can induce a failure current that results in a tempera-
ture display different of the effective temperature.
Always ensure that temperatures of thermocouple and Regulus are the same to achieve a correct tem-
perature result. Wait a certain time after storage or transport the Regulus and a thermocouple in differ-
ent temperature environments before correct temperature measurement can be achieved. Depending
on the temperature deviations a wait time of 15 to 60 minutes is recommended.
Reduce interference: Induction systems
may cause interferences to the temperature
measured with a thermocouple. To reduce
this, the inductor and the heated object
must be connected to the earth terminal on
the back of the Regulus with a ground wire
of at least 4 mm².
3.1.2 Digital Inputs
The instrument is equipped with 6 digital inputs to operate the instrument
partially extern. Every input can be assigned to one of these functions (see
Software 5.4 Device configuration).
24 V has to be connected either with a push button or switch to an input to
activate its function (see under 3.1 Connector X3).
Start / Stop controller (push button):
Every trigger starts or stops the controller in turn.
Activate controller (switch):
Controller is active as long as input signal is active (24 V to the desired pin).
Emergency stop (switch):
Controller is active if 24 V is set. Without voltage input controller is deactivated, all outputs will be set
to 0 V or 0 mA (safe condition).
Reset error (push button):
Resets the controller in case of a device error. The controller tries to continue operation.
Program step trigger (push button):
In program mode the next program step can be selected.
Enable front panel start (push button):Front panel can only be done with additionally connected
and pressed push button (see 3.1 Pin Assignment Connector X3). The input for this function can
be selected. Stop function on front panel is always executable.
INFO:
Enable front panel start is a security setting to prevent an accidentally controller start.
Deactivation is possible but not recommended.
External program selection (switch), (only inputs A - E): allows the external selection of the manual
mode or a program. The inputs are binary coded, i.e.:
- With a digital input only a program or "Manual" can be activated. With 2 inputs are 3 programs
available, with 3 inputs 7 programs with 4 inputs and 15 programs with 5 inputs, all 26 programs
are available.
At all combinations not listed, "manual" is activated.

3.1.3 Digital Outputs
The instrument is equipped with 7 digital outputs. Via software every out-
put can be assigned to different functions (see 5.4 Device configuration)
The state of the digital outputs can be adjusted:
NO (normally open): outputs have in active state 24 volts to the pins and
in inactive state 0 V (output max. 100 mA, load min. 300 Ω).
NC (normally closed): outputs have in active state 0 volts to the pins
and in inactive state 24 V (output max. 100 mA, load min. 300 Ω).
Additionally a verification time and hold time in ms can be set (see 5.4 De-
vice configuration):
The verification time defines how long an event is active until the out-
put is activated (for example, the temperature is exceeded).
The hold time defines the time how long the output is hold at least. This feature is useful e.g. if a
PLC error signal requires a signal time of at least 10 ms for a proper recognition.
Selectable Functions
No function
Output is always set to logic 0
Limit value output
If activated a temperature value can be entered from where a contact has to be active (LEDs on the
Regulus show the active state. Additionally outputs A-D are switching the relays). The hysteresis is
the value at how many degree below the limit value the output is switched back. Additionally it can be
selected if the contact is active with exceeding the temperature value or if the contact is inactive (logic
NO or NC).
Message controller active
Output is active if controller is active (in manual mode, program mode or open loop mode).
Message controller ready
Activates the output if a pyrometer or thermocouple is found or the analog input detects a 4 mA signal
(indicates that without connection error the controller is ready to use).
Setpoint limit 1 / Setpoint limit 2
The setpoint limit is a limit temperature above or
below the setpoint temperature that should not
exceeded or to be below. Two setpoints can be
defined. The output is activated if the measured
value exceeds the defined setpoint value. The
output is also activated if the measured value
falls below the defined value. Entry of the set-
point value has to be done relative to the set-
point, positive or negative, e.g. 20°C if the setpoint value is 800°C and the output should be active at
820°C.

Setpoint band
The setpoint band is composed of the 2 setpoint limits and defines a range within the temperature
has to be. The output is activated if the measured value is outside the defined value.
Control of generator
Allows to enter generator-specific settings for shutdown the generator if the control output falls below
a limit value and reclosing (see under 5.4 Device configuration control of generator).
Message error
Output is active in case of an device error (see 6.2.1 Status Messages / Error codes)
Message control successful
Output is active if control process is finished:
- in manual control: if ramp time and/or hold time is finished
- program mode: if the complete program is executed (with all optional replays)
Note: The output signal is not set if a new controller start is faster than an adjusted verification time.
Control of heating process (belongs to "peak detection“, see under 5.4.2 Create Program Se-
quences Peak detection): Activates the output during the verifying period.
State of input A (not selectable on output G): Detects the state of input A and activates the output
accordingly.
3.1.4 Analog Outputs
2 analog outputs are available:
Control output: According to the requirements the control output can be set to
0-20 mA, 4-20 mA, 0-10 V, 0-5 V or 10 V PWM mode.
Actual value output: According to the requirements the actual value output can be set to
0-20 mA, 4-20 mA, 0-10 V, 0-5 V.

4.1 Operation Modes
Different operation modes can be executed with the Regulus (further explanations are to find in the cor-
responding sections of the software descriptions):
Manual mode
In manual mode an actual value and the required PID parameters are set.
Manual mode can be started directly on the device, per remote push button or via software.
Program controlled
When operating as a program controller, the controller starts predefined program sequences created
via software. Up to 26 programs with a maximum of 256 steps each can be created (limitation: pro-
grams + steps max. 990).
A program start can be done via software or directly on the Regulus. Programming itself only can be
done via software SensorTools.
Open loop mode
Starts a control process without feedback from a connected sensor. Anyway, a pyrometer or sensor
can be used to display the current measuring temperature.

5.2 Program Start
Starting the software opens
the main window of the pro-
gram. The Regulus is not con-
nected automatically.
5.2.1 Connecting the Regulus
For successful communication with the Regulus it has to be connected first. The status line on bottom of
the software window shows the current connection status:
Select the computer’s com port the device is connected to. Also a COM port must be
selected when connecting via an USB converter.
Note: Ensure the interface used at the PC is selected on the Regulus. If necessary
change the setting directly at the Regulus, changing via software is not possible (see
6.2 Menu setting <COM Interface > RS).
Press the search button if the com port is unknown. The Regulus will be connected
automatically if the port is found.
Press the connect button to connect the Regulus to the software. All controller set-
tings and programs will be read out and displayed in the software.
The button changes to “Diconnect” when connected. Click to disconnect.
The status line informs about device and connection status.
A detected Regulus shows temperature information, the type of operation mode and a (preset) setpoint.
Follow the instruction to setup the Regulus.
INFO: a Regulus connected to the software has blocked push buttons.
"Keylock" appears when pressing a key.

A Sensortherm pyrometer (digital sampled) is connected via serial interface and the temperature
range is automatically read out.
A Sensortherm pyrometer (analog sampled) is connected via serial interface and analog input, but
the analog output of the pyrometer used as signal transmitter. This connection can be selected if a
very rapid evaluation is necessary which does not work via interface, for example, at long interface
cables or when using high-speed pyrometers.
"Sensor settings" is used to configure pyrometer settings
For analog sampled devices the current output and temperature range must be set. The Regulus
can handle temperature ranges from 0-3300°C, the entered “temperature range” is the range of the
analog output range.
Thermocouples are available depending on the model.
At measurement errors, the temperature curve can be provided with an
offset.
Combine measuring devices:
All connected measuring devices can be combined as a unit and a transfer temperature are defined.
Two measuring devices can measure sequentially, for example, a thermocouple for the lower tem-
perature range and a pyrometer for the higher.
4 combinations are possible (selection A, B, C, D). Then, each selection can then be used for the
measurement process, in program mode even each program can be assigned another combination
(manual mode: see 5.4.1 Start a Control Process in Manual Mode -> “Sensor adjustment”. Pro-
gram mode: 5.4.2 Create Program Sequences setting field = Measuring device selec-
tion). is used to assign 2 connected measuring devices to a selection:
- Component 1 and 2: each selection will be done by the connected measuring devices. However,
component 1 is always defined by the lower temperature range.
Use the arrow key button to swap the measuring devices.
Example: Two sensors are connected, a NiCrNi thermocouple on X10 with a temperature range 0-
1350°C and a pyrometer connected to “X1” with a temperature range of 350-1800°C.
The bar graph shows the complete temperature range, the handover temperatures of both compo-
nents and the resulting hysteresis (temperature difference).
- The handover temperature / hysteresis defines the temperature at which the temperature meas-
urement is hand over from one measuring device to another at increasing or decreasing tempera-
ture. The difference is the hysteresis.
- Upper measuring limit component 1: handover temperature, where component 1 changes to
component 2 when the temperature is increasing.
- Lower measuring limit component 2: handover temperature, where component 2 changes to
component 1 when the temperature is decreasing.
Note: The handover temperature of component 1 has to be higher than of component. 2

5.3.2 Pyrometer Alignment
Precondition of a successful control process is a steady
temperature capturing. Align the pyrometer or sensor to an
area where a control process can be influenced (e.g. to a
faster heated border than a centered alignment).
5.4 Device Configuration
Here basic device settings are made.
Miscellaneous settings
- Setpoint deviation: The setpoint deviation is a global parameter that controls the program flow.
The setpoint level is the maximum deviation between actual value and nominal value to consider a
value as controlled successfully and start the next step.
- Range setpoint input: Defines the temperature range for the analog setpoint (possible range be-
tween 0 and 3300°C). The function is activated in the parameters control window.
- Key lock: To lock or unlock the key functions on the Regulus.
- None: All functions can be changed using the buttons on the unit.
- Active: The buttons on the unit are disabled.
- Menu lock: activates an input field for a 4-digit PIN code, which enables to protect changing of
parameters (PAR key) on the device. If activated, this code must be entered on the device be-
fore parameters with the PAR button can be changed.

Analog outputs (see 3.1.4)
- Measurement temperature (actual value output) / control output: Select the required output for
the connected device.
- PVM interval (period’s time) (only available if 10 V PWM is selected):Select the value corre-
sponding to your connected device.
- Adaptation: the temperature range span can be scaled down in order to adapt it to specific meas-
urement conditions.
Press the test button
to check the functionality of the
analog outputs.
Moving the slide control will set
values for the selected output.
The “On” button will transmit
the test setting to the controller
output, the Regulus shows the
result.
As notification on the Regulus a
blinking “Testfunction” text ap-
pears.
Digital input configuration (see 3.1.2)
Select the desired function in the list box for each (connected) input.
Digital output configuration (see 0)
Select the desired function in the list box for each (connected) output.
Every output has its corresponding settings in the line beside the output function.
- Setpoint: Values can be entered only if “Limit value output” is selected.
- Hysteresis: Only active if “Limit value output” is selected
- Logic: Sets the general functions of the output. NO: “Normally Open” or NC: “Normally Closed”
- Extended settings: Depending on the selection are either available:
Time settings: A verification time and a hold time can be set:
- Verification time: select “immediately” to activate the output function immediately when hap-
pening. A time between 1 and 65535 ms delays the activation accordingly.
- Hold time: A time can set to remain activated output for a desired time.
- None: signal is active as long as the function is active
- Process start: signal is active up to the next start (of a program or manual start)
- Time value between 1 and 65534 ms: signal is active for the entered time.
Reference: for selecting which measurement temperature to be used for the output control (which
pyrometer or which sensor or sensor combination).
Setting control of generator
Note: This output sets the time settings to 0):
- Control value limit: Defines the limit the control
output should be activated (minimum generator
power, if this cannot controlled continuously down
to 0%). Below the set value the control function is
switched off).
- Pick up verification: specifies the time the controller output must reach the control value limit
without interruption, before the output is activated.
- Drop down verification: specifies the time the controller output must be less the control value lim-
it without interruption, before the output is deactivated.
- Start delay: Delays checking the control value limit at a controller start.
- Output activation by control start: Activates the output directly at the control start without check-
ing the pick-up verification and start delay time.

Setting heating control
The output switches at a detected temperature peak (see in 5.4.2 
Peak detection function). Switching back of the output can be de-
layed.
With the Test function digi-
tal inputs and outputs can be checked for er-
rors.
Click on an “Output control” check box to acti-
vate the corresponding output. A green LED
symbol signalizes the activation.
Digital inputs are marked with a green LED
symbol if connected and active.
Activation of the outputs will also activate the
LEDs on the Regulus.
As notification on the Regulus a blinking “Test-
function” text appears.
CAUTION! Using the test function will activate the selected outputs.
All connected systems will start working.
Always pay attention to the security instructions of these systems!
Temperature unit
The temperature can be displayed and entered in °C or °F.
(Changing the mode will not change the entered values, no conversion will be done).
Service functions
To back-up, for printing or restore device parameters or cre-
ate service files for remote diagnosis of problems.
- Create configuration file: A configuration file includes all
device settings made by user. This can be used e.g. to
setup a new pyrometer with the same values and settings
or to save the current status in case of a device replace-
ment.
- Load configuration file: load a previously saved configu-
ration data in the pyrometer.
- Print parameters: Prints the parameters of the currently
connected device.
- Print configuration file: Prints a saved file.
- Factory settings: Resets the device to its factory defaults.
- Create service file: A service file includes all device data
and all software settings made by user. Creating such a file
can be useful if a controller problem can’t be solved and help from our service could be useful.
- Upload service file: Transmitting a (possibly modified) file to the device it was created from.
Serial Interface
For setting the baud rate (not with USB), device address and inter-
face delay (in the case of faulty data transfer).
Note: The serial interface type and the device address can be
changed directly on the Regulus (see 6.2 Menu settings under
<COM Interface>).
Device addresses from 00 to 97 are valid. Addresses 98 and 99 are
with special functions. The global address 99 can be used to com-
municate with every controller, independent of the set device ad-
dress. This allows communication with devices with unknown addresses. The address 98 is a group
address used for RS485 devices in bus operation. With this address devices do not answer, useful to
change parameters of all connected devices at the same time.

Data Collection (buffer mode) (Only available when connected via serial in-
terface. Not with USB, since this always runs with the highest possible speed).
The measurement data transfer from Regulus to the PC can vary depending on the requirements and
computing power. Speed and transferable amount of data are dependent on the baud rate and the
data mode. In the data collection window are shown the amount of measured values determined by
calculation for each baud rate and each mode. When set to "Auto. interval adjustment ", the corre-
sponding values of baud rate selection will be entered automatically in the field on bottom right. When
required, they still can be adjusted manually, for example, if the calculated values still give problems.
USB always works internally with the baud rate 921.6 kBd.
ASCII mode: The Regulus al-
ways transfers separate read-
ings to the software and shows
each in the graph as a pixel. In
addition to the transmission of
measured values, also regularly
status values are transmitted
(limit contacts or active laser
targeting light...), so that meas-
ured values do not always ar-
rive at the same time interval.
For most applications this
speed is sufficient, a modern
PC can transmit every 5 ms a
value at 921 Kbits.
With buffer mode: Measure-
ment data are temporarily
stored in the internal buffer of
the controller and periodically
transferred to the software in
blocks, additional control infor-
mation (I/O states, laser target-
ing active,...) will be transmitted
cyclically. The buffer interval
defines how fast the internal
FIFO buffer of the Regulus is
filled. The shorter the time, the
more data per communication block will be transferred.
An interval time set too fast in relation to the baud rate and computing power leads to buffer over-
flows, which are represented by vertical bars in the graph. A modern PC reaches intervals of about
0.3 ms at 921 Kbits without buffer overflow, at 57 Kbits intervals of approximately 3.6 ms. If buffer
overflows occur, the interval time can be increased, the baud rate can be increased or unnecessary
programs and background services be stopped. A minor impact also has the reduction of the maxi-
mum data records in memory (see under 5.6 Data recording settings).
- Display mode:
- Controller display: In the software window
the actual measured temperature, the setpoint
and the control mode are displayed.
- Sample display: The software settings win-
dow, the temperatures of all sensors and ac-
tual value and setpoint display. This can be
used to display the temperatures of all meas-
uring instrument combinations.

5.4.1 Start a Control Process in Manual Mode
In manual mode, a setpoint temperature and necessary PID
control parameters can be entered directly into the software
or at the Regulus. Starting the process will start to control to
the setpoint temperature with the set parameters. The con-
trol process will be hold until is finished manually or automat-
ically if a hold time is entered which runs if the setpoint value
is reached.
Parameters can be changed during a running control pro-
cess and will be taken over by pressing “Enter” on the key-
board. Invalid values will be automatically corrected to the
next possible value.
Note: all values in this “Control parameters” window can also
be set directly at the Regulus (see 6Device Handling).
INFO: At control process where the temperature is
approached from a temperature higher than the
setpoint temperature should be optimized selecting
this field. If setpoint temperature is reached from
upper temperature the integration sum of PID con-
trol is set to 0. In this case undershooting the set-
point temperature is avoid in the control process.
Control mode : Switching between manual
mode and stored control programs. The mode is displayed once again in the upper display.
Measuring device selection :
To set, which measuring device selection is
used to carry out by the measurement (see
5.3.1 Select / Combine Measuring devices).
General parameters
- Setpoint: Setpoint specification
- Analog setpoint: when activated, the analog input is used to specify the setpoint externally via
voltage input (see under 3, Electrical Connection Connector X3 External Setpoint Settings).
- Ramp time (in 100 ms):The setpoint temperature will be approached by increasing the tempera-
ture with a uniform gradient of the temperature within the entered time.
- Hold time: to hold the reached control output value a hold time can be set. Control process is con-
tinuing automatically after reaching the setpoint temperature and expiring the hold time.
PID parameters
- Xp: The proportional band represents the reciprocal of the gain of the controller (Entering 0.1-
1000%, 0.1 = highest gain, 1000 = lowest gain).
- Ti:The integral time constant represents a kind of smoothing or delay (Note: Ti is a multiple of the
sampling time. Therefore, changes in the sampling time have an impact on this value).
- Td: The derivative time constant slowdowns the rapid rise to prevent overshooting (Note: Td is a
multiple of the sampling time. Therefore, changes in the sampling time have an impact on this val-
ue).
- Sampling time: Select how quick temperature values will be read out of the sensor. Select the pa-
rameter depending on the inertia of the heating process (Note: Ti and Td are a multiple of the
sampling time. Therefore, changes in the sampling effect changes in Ti and Td).

Power adjustments
- P-min: The minimum control output power defines the power which is to the control output at least.
- P-max: The maximum control output limits the power to the entered value.
- P-zsc: Limits the control output power as long as the beginning of the sensor’s or pyrometer’s
temperature (zero scale temperature) range is reached. This is useful to avoid a too fast start of a
heating process because the object temperature is out of the pyrometer’s temperature range.
Threshold values (values in this field are not available directly in the parameters menu of the Regu-
lus):
- Setpoint limit 1 and 2: Activates every selected “setpoint limit” output 1 or 2 (see 0Digital Outputs
and 5.4 Device configuration) if the set temperature is exceeded or falls below. The required tem-
perature has to be set relative to the setpoint temperature (in the control parameter field), not as
absolute value.
- P dynamic: Limits the power, the control output can control suddenly (standard 100%).
AutoTune settings
- The AutoTune target temperature defines the temperature that is used for Xp and Ti determina-
tion. The entry occurs in % and defines the difference between setpoint and actual value (example:
setpoint is 1000°C, the measurement object is cold which means the actual value is the pyrome-
ter’s beginning of temperature range and thus, for example, 500°C, then the target temperature is
750°C at 50% factory setting). Only a value below 100% prevents a temperature exceeding during
P-I-determination and thus a possibly material destruction due to overheating.
- Next start with AutoTune: Starts the AutoTune function prior to the next control start, then imme-
diately the control process starts with the found PI parameters. This also works with an external
control start. The function is only active for one controller start and will be deactivated (unchecked)
with the next control start.
- Controller start always with AutoTune: starts AutoTune prior to every control start, then the con-
trol process directly starts with the found PI parameters (also works with an external controller
start).
The AutoTune function enables to detect automatically useful values for the proportional
band Xp and integral time constant Ti. The function tries to find the values Xp and Ti without over-
shooting the setpoint temperature.
NOTE:
AutoTune usually results in only a guide, their further optimization is necessary then.
Starting the Controller
Press Start to start the control process. Pressing the start button at
the Regulus will also start the procedure in the software.
Press stop to quit the process.
Press the red record button to store temperature and control values to the PC’s hard disc.
Note: Recording can be started simultaneously with controller start if corresponding setting is made
(see Data recording settings under 5.6: under “automatic recording by active control” and if required
“automatic end of recording by inactive control”).
