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 tempera­ture 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 operat­ing 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 instal­lation 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 (accord­ing 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 in­puts). 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.

3.1.1 Thermocouple Types -K and -S

Please consider the special characteristics of thermocouples if the device is equipped with correspond­ing 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 tempera­ture display different of the effective temperature.
Always ensure that temperatures of thermocouple and Regulus are the same to achieve a correct tem­perature result. Wait a certain time after storage or transport the Regulus and a thermocouple in differ­ent 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 out­put 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 set­point value has to be done relative to the set­point, 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 cor­responding 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: pro­grams + 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.

 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 tem­perature 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”. Pro­gram mode: 5.4.2 Create Program Sequences  setting field = Measuring device selec­tion).

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 0­1350°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 compo­nents and the resulting hysteresis (temperature difference).

- The handover temperature / hysteresis defines the temperature at which the temperature meas­urement is hand over from one measuring device to another at increasing or decreasing tempera­ture. 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 be­tween 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 be­fore parameters with the PAR button can be changed.

- 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 lim­it 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.



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 cre­ate 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 replace­ment.

- Load configuration file: load a previously saved configu­ration 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 inter­face 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 com­municate with every controller, independent of the set device ad­dress. 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 corre­sponding 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 al­ways transfers separate read­ings 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 meas­ured values do not always ar­rive 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: Measure­ment data are temporarily
stored in the internal buffer of
the controller and periodically
transferred to the software in
blocks, additional control infor­mation (I/O states, laser target­ing 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 over­flows, 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 maxi­mum 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 win­dow, the temperatures of all sensors and ac­tual value and setpoint display. This can be
used to display the temperatures of all meas­uring 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 con­trol process will be hold until is finished manually or automat­ically if a hold time is entered which runs if the setpoint value
is reached.

Parameters can be changed during a running control pro­cess 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 6 Device 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 con­trol is set to 0. In this case undershooting the set­point 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 tempera­ture 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 con­tinuing 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 val­ue).

- Sampling time: Select how quick temperature values will be read out of the sensor. Select the pa­rameter 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 0 Digital Outputs
and 5.4 Device configuration) if the set temperature is exceeded or falls below. The required tem­perature 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 imme­diately 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 over­shooting 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”).

General Program Parameters

Settings in this field are only valid for the current program.

INFO: A control process where the temperature is approached from a temperature higher than
the setpoint temperature, the controller cannot control active, as the attainment of the tempera­ture depends on the cooling rate of the material. If the setpoint temperature in this case is
reached from the higher temperature, the sum value of PID control is set to 0 to avoid an under­shooting of the setpoint temperature as good as possible.

 Start delay: The program start can be delayed (0 to 65.535 s)
 Power till zero scale: Limits the control output power as long as the beginning of the sensor’s tem-

perature 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.

 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).

 P dynamic: Limits the power which the control output can control suddenly (standard 100%).
 Minute base: Changes the time unit of ramp time and hold time to minutes instead of 100 ms base.
 Open loop mode: Starts a control process without feedback. A pyrometer or sensor is not required in

this mode, a selected sensor in the sensor tab has no influence (see 5.3.1 Select measuring devic­es). Anyway the sensor or pyrometer can be used to check the object temperature.

In open loop mode a value for the controller output power (P-Set) has to be set to the program steps.

 Cycles: To select how often a program shall start again if finished (1 - 65535 and infinity can be se-

lected).

 Gradient ramp: A gradient in degree per second can be entered instead of ramp time values.
 Peak detection: Automatically detects a defined positive or neg-

ative temperature peak to automatically go to the next program
step. Additionally, the digital output (see 0) “Control of heating
process” can be activated at detected temperature peak. It is ac­tivated when the program is running and during the verify time. At
a detected temperature peak the output is set to inactive (where
required with a delay if an appropriate hold time is set).

Peak detection settings:

- Verify time: Time from program start, within

the temperature peak should to be recognized
(up to firmware 2015_10: entry 0.001–65.535 s;
from firmware 2015_11: entry 0.1–6553.5 s). If
no temperature peak is detected within the veri­fy time, the program will be canceled. If a tem­perature peak is detected, the next program
step is executed and the verify time has no
function anymore.

- Activation difference: Specifies the tempera­ture where the peak detection starts to operate.
The value is entered relative (by difference) to
the setpoint.

- Detection difference: Specifies the sudden
temperature difference to the setpoint value
that identifies the difference as peak.

- Program step: defines the current program
step, the peak detection is to be executed.

- Peak form: defines whether the peak detection should work with sloping (negative) or rising tem­peratures (positive) or in both directions.

Entering Values for a Programmed Process

 Setpoint: Setpoint specification
 Ramp time (in 100 ms): The setpoint temperature will be approached by increasing the temperature

with a uniform gradient of the temperature within the entered time (0.0 s is off). During ramp time the
temperature is controlled continuously. A maximum ramp time of 655.35 °C/sec is possible.

 Hold time: to hold the reached control output value a hold time can be set. Control process is contin-

uing automatically after reaching the setpoint temperature and expiring the hold time. During hold
time the temperature is not controlled, only hold.

 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 value).

 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-Set (only available in open loop mode): a value for the controller output power has to be set.
 Ɛ1 / Ɛ2: To enter the material properties (emissivity or emissivity slope for ratio pyrometer) for py-

rometers connected to Component 1 or 2 (under measuring device selection for ratio
pyrometers, separate measuring channels can be selected).

 Limit 1 and 2: If “setpoint limit 1” or “setpoint limit 2” is select as digital output (see 0 Digital Outputs

and 5.4 Device Configuration) the corre­sponding temperature can be set for every
program step.

 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).

 Table handling:

- Adds a program step behind the current line. Current values will be taken over.

- Imports values from the manual entry field in the row

- Deletes the line

Transfer: Transfers all programs (the program list) to Regulus.

5.6 Graphical Display / Data Recording

The graph window is used for monitoring the sensor temperature(s) and the control process. It shows
measuring information once the Regulus and a sensor is connected.
The colors in the graph show the measured temperature (the temperature, which is responsible for the
control process and can be seen on the device display or in the control window), the setpoint tempera-
ture (only if controller is started), the temperatures of the sensor combinations (see 5.3.1) and the pow­er of the control value output.

The graph window in the main window shows the temperature profile in time.

 The time axis (horizontal axis labeling of the X-axis) indicates the current time.
 Scale X-Axis allows to set the time at which the graphs window is filled with measured values. If the

time is changed, the graph rebuilds itself from the window center.

- rebuilds the graph from the left.

- Sets a recording time to 0 (has only effect in the playback file)

 Scale the graph: Beginning and end of temperature scale (left) and control out-

put (right) scale can be adjusted to represent the relevant area reasonable

- Scale per mouse click: With the green arrows of the upper and lower scale
range is changed

- Scale per entry: The upper and lower temperature can be entered via the
keyboard.

- Scale with mouse drag: With click, hold and drag on the gray arrows, the
start and end or the entire area can be moved.

- Automatic scale: automatically adjusts the scale (+10°C above the maxi­mum value and -10°C below the minimum value):

- reads out the Regulus temperature range (0-3300°C)

- selects the range from all selected display graphs and always the

highest measured value.

 Information field

- RD-1365 in the example on the right shows Regulus model and serial number.

- The sampling time T-Sample Shows the time between the last two received

measured values.

- The control time T-Contr. shows the time a control process is running al­ready.

 Select display graphs:

- Depending on the device type, different graphs can be displayed or hidden; the color can be

changed by right-clicking on a color field.

Select display graphs (right click
to change the color settings of the
graph), activates or deactivates

 The transferred measured value data can be recorded on hard disk for subsequent analysis.

Click the recording button to start and stop recording, the button flashes when recording is active
( ), Pause interrupts the recording. When recording is active, a red reference text is dis­played above the graphics window (pyrometer model-serial number: write file pyrometer model-serial
niumber_sequential number.r2b).

Data recording settings

- File options (The selected option is displayed in the main

window above the graph with: pyrometer model and serial
number, file name and a running number):

- Overwrite file (Overwrite mode): Overrides the same
file with each new recording.

- Create new file (Fileindex mode) creates a separate
file for each recording.

- Append data (Append mode): With each new record­ing, the new values are appended to the previous one

- Storage interval: Writes a reading in the file with the set
storage interval. At 0.0 s, the storage is done as fast as
possible (depending on baud rate and buffer mode).

- Automatic recording by:

- Active control (shows only effect when equipped with a

PID controller): Starts recording automatically when a
controller-start takes place (also at an external start).

- Active I/O port: Starts recording when a digital input or

output is active. The port selection will be done at I/O
port at the bottom of the window.

- Back-time recording: If the record button is pushed (or recording is activated by active I/O port
and setting "automatic recording by active I/O port" is checked), values are stored retroactively for
the entered time but only as many, as entered under "Maximum data sets in memory".

- Automatic end of recording by:

- Inactive control (shows only effect when equipped with a PID controller): Stops recording when

a control process is stopped (even with automatic or external stop, error, etc.).

- Inactive I/O port: Stops recording when a digital input or output is disabled.

- Post-record of recording: recording can be continued for a while if control process is stopped,
e.g. to record a cool down process

- Maximum data sets in memory: Number of measurement data sets (consists of measuring tem­perature, emissivity, device temperature, setpoint-value...), the program maximum keeps in the
memory to display this on back-time recording or in the playback window (MEM button), (data re­cording, however, is only limited by disk size).

- As I/O port an digital input as well as output can be selected

INFO: If an output is used, the assigned function can be used for controlling the auto-

matic recording, for example for automatic recording when a certain temperature is ex­ceeded (limit switch activated).

5.6.1 Data Playback



Press the playback button in the main windows to open a playback window and show the last

measured values.



Press the “Load data” button to open a saved file and display in the playback win-

dow. To compare several measurement curves, you can select several files, each file will be opened
in a separate window. The SensorTools Viewer can also be opened by double-clicking on a data file.



Press “Copy data file” to copy one or separate files into another folder. Select the
files you want to copy, the original files are not removed. In the next window a folder can be selected
where files should be copied. Then a file name is suggested containing date and time. All selected
files will be numbered in sequence with the chosen name.

Hold down the mouse button and drag a selection to view a detail. To select details, a selection can be
dragged with the mouse. To move the view, on the temperature or time scale the view can be moved
with the mouse (middle of the scale) or the upper and lower limits are changed (upper or lower end of
the scale).

5.7 Communication / Options

 Sprache / Language: Selects between German and English user interface.
 Print configuration file has the same function as in the device configuration under "service func-

tions": Prints a stored device settings file.

 The terminal field is a service field to communicate with the Regulus or a connected Sensortherm

pyrometer via interface commands (see 8 Communication via Serial Interface / Interface Com-
mands). Type in commands without device address. In standard use of the Regulus no entries are
required in this field.

 Flash CS / IF / RD / RF firmware: The Regulus firmware can be updated when a new version of

Sensortherm was provided. Each SensorTools software has integrated the latest firmware with the
delivery date, and recognizes if it is not up to date when connecting a Regulus. The latest software
and firmware is available on the home page in the download area under
www.sensortherm.de/en/download-section.

- Click Flash CS / IF / RD / RF firmware to update the firmware

- After a warning note, the Regulus is disconnected, if it is not.

- Select in the next window the firmware from the proposed Regulus directory or another directory,

for example, if downloaded and stored.

- The firmware will be installed automatically, an information box informs about the success.

- For further use the Regulus must be reconnected to SensorTools.

 Flash H3 / M3 / DI / DS firmware: An M3 or H3 pyrometer must be connected directly to the PC, to

update it to a new firmware version. The update process takes place by the SensorFlash software,
further procedure is described in the M3 / H3 instructions.

5.7.1 Spot Size Calculator

The spot size calculator is used to calcu-

late the pyrometer’s spot size diameter in

front and behind the focused measuring
distance. To do this, fill the white fields
with the basic data (see Spot Size Tables
in the corresponding pyrometer manual),
then values in the gray fields can be cal­culated.

6 Device Handling

If connected to the power supply the instrument is ready to use. Interrupt the power supply to switch off
the device.

 Main display

Shows the measured temperature of the connected pyrometer or sensor (upper display line) and de­pending on the measuring mode the setpoint temperature (manual mode) or the selected program
with current program step (lower display line)

- Underflow is displayed if temperature is below beginning of pyrometer’s temperature range

- Overflow is displayed if temperature is above end of pyrometer’s temperature range

 Active outputs A-G

An activated output is indicated with an illuminated LED.

 Status LEDs

- RDY (Ready): The device is ready for use.

- ACT (Action): Illuminated at active control processes.

- ERR (Error): Illuminated in case of a device error, additionally an error message is shown.

6.1 Key Functions

Parameter: Press the button repeated to get access to all settings sequentially (see 6.2 Menu
Settings). Every category is displayed in triangular brackets (e.g. <Setpoint>). A shown value

in the lower display line can be changed with the arrow keys. Without value a sub menu is
reached with “Enter”.

Arrow keys: Settings can be done with the arrow keys. Keep the button pressed to change the
values faster, reasonable for example when changing a temperature value. A changed value is
shown by a blinking display and will only be saved when pressing “Enter”. If no changes are
made within 60 s the main display shows the current measuring temperature again.

Laser targeting light: In measuring mode this button can be used to switch on and off a laser
targeting light of a Sensortherm pyrometer.

CAUTION, Laser Radiation, Laser Class 2:

 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 intentionally closed and the head

immediately moved out of the beam.

Enter: Press Enter to take over a changed value.
Changing the setpoint value in manual mode will delay the program start function of 2 s.

Program start and stop: Starts and stops the manual mode or a program (depending on the
selection). For successful start the parameter mode has to be finished (displaying a parameter
category has to be finished). Either press PAR as often as measuring temperature is displayed
or wait 60 seconds. Then controller start is possible.
In case of a device error (see 6.2.1 Status Messages / Error Codes) this button is also used
to quit this message.

8 Communication via Serial Interface / Interface Commands

Interface commands are used to communicate directly with the Regulus or with a Sensortherm pyrome­ter via the Regulus. Commands can be used to write an own access control or can be entered in the
terminal field of the SensorTools software (see 5.7 Communication / Options) or entered via a termi­nal software.
Note: The interface commands do not include the possibility to write programs. Also some special
commands are omitted, if further help is necessary please contact our technical service.

 Data is exchanged in ASCII format with the following transmission parameters:

8 bit, 1 stop bit, even parity (8,1,e)

 Command sequence to write parameters:

2-digit device address  command  parameter  <CR> (Carriage Return)

 Command sequence to read out the current set parameters:

2-digit device address  command  <CR> (Carriage Return)

 Device address (also see in 5.4 Device Configuration under Serial Interface):

in the terminal field of the SensorTools software no address is required.

 Pyrometer commands: A connected Sensortherm pyrometer can be addressed directly by

writing the first command capitalized.

 When writing with valid parameters, the response will be ok + <CR>
 When writing with invalid parameters, the response will be no + <CR>

Example:

Input in terminal programs

with device address 00

Input in terminal program of SensorTools
without device address

00ar1<CR> sets the controller output to 4-20 mA
