Programming skills not necessary
Construction
MPC is a versatile and flexible system for
controlling and monitoring electric trace heating
applications.
The system is modular in construction and can
therefore be adapted flexibly to the respective
requirements of the plant or equipment.
The construction of the control system is based on
standard I/O bus systems and was developed specially to meet the demands of electric trace heating.
The system is modular and can be adapted to the
respective application’s specific requirements by
combining individual modules.
Diverse function modules are available to allow its
operation as a two-state controller. They register
temperature, load and residual current and diverse
control signals, e.g. output signals from limiters.
MPCnet enables solutions extending from simple
temperature recording systems to centrally controlled temperature regulation, limitation and
monitoring.
The system is easy to plan and configure. PLC
programming skills are not necessary. The software
and touch panel make it simple for the operator to
set parameters for the individual heating circuits.
An output module provides floating contacts to
emit alarms. It is also used to actuate the external
contactor for switching the heating circuits.
Independent complete modules are available for
each heating circuit to allow its operation as a proportional controller. These regulate the outputted
heating power as well as the holding temperature.
The load and residual current are registered for that
purpose. The heating circuits are activated through
an integrated triac then.
The MC32 controller module accesses the various modules through the system bus. A controller
module provides up to 32 heating circuits. This
number can be increased by adding more modules
to the bus.
An optional gateway ensures communication to
the higher-ranking control system and to the touch
panel. The parameters for the modules can be set
by means of software or a touch panel.
Function
The load and residual current monitor constantly
checks the entire heating system and ensures that
the heating cables and temperature sensors always
function reliably. Alarms are given if values exceed
or fall below the pre-defined load or leakagecurrent limits.
The MPCnet Process Designer software can be
adapted individually to the user’s requirements
and constantly show the state of the heating
system. Statistical data on the current and energy
consumption are determined by means of the
integrated data logger. This provides information
on the condition and ageing status of the material
that is being used.

MC32 Controller Module
Features
■Regulation of up to 32 heating circuits or modules
■User-defined group alarms
■Number of heating circuits extendable at will
Description
The MC32 controller module regulates and monitors up to 32 heating circuits. It
flexibly accesses the individual remote I/O modules by means of the bus system
integrated in the DIN rail.
Individual upper and lower limits can be assigned to each monitored value and
individual alarms emitted by means of the MPCnet control system’s digital outputs.
By inserting more MC32 modules into the bus, the number of heating circuits to be monitored can be increased at will. Two setpoint values can be
assigned to each heating circuit and changed by means of an external switching
contact.
In addition, all individual alarms can be emitted through the MC32 module’s
group alarm contact to an indicator light or suchlike. The bus status signals and
alarms are also indicated by means of LEDs.
The MC32 monitors parameters, such as temperature, overheating, load current, residual current, and external status signals such as rccb auxiliary
contacts, limiter alarms, manual switches etc. for each of the 32 heating circuits
individually
Connecting the GW32 gateway and PA00 touch-panel allows a transfer not only
of the setpoint and actual values but also of all alarms into a higher ranking control. All of the control system’s parameters and alarms can be altered or acknowledged from the control centre.
See System Description for the Installation Instructions.
Up to three temperature sensors per circuit are monitored, whereby the controlled
variable is fixed in relation to one sensor. The other sensors serve to monitor a
high and a low alarm value.

to meet the requirements of a wide variety of applications and tasks.
The parameters are set locally by means of the intuitive user menu or a PC. Remote querying or configuration through the RS485 interface is possible.
Function
The setpoints set on the device are constantly compared with the temperature levels measured on the
heating circuit.
If there are deviations, the external relays are
triggered accordingly. The temperature deviation is
1 K at most. An alarm is triggered if the temperature
drops below or exceeds a set limit. The alarm message is also displayed on the LED display.
The load and leakage current and the heat output
can be monitored also.

Function
Features
 Extremely compact
 Different temperature range combinations

 Suitable for use in Zone 1 areas
 Temperature can be set in Zone 1 areas
 Alternative versions available
Description
The 5 A capillary tube thermostat, STW, is a
compact change-over controller housed in an
EEx e certified polyester enclosure.
Heaters, fans, motors and other equipment are
energised and de-energised by means of this
thermostat when specific temperature ranges are
exceeded. This device can also be used to control
the temperature in air or on various surfaces.
Connection diagram
Any change in temperature at the sensor bulb
causes a change in the volume of fluid in the
measuring system, which in turn results in a
movement of the diaphragm membrane. This
membrane is connected to a mechanical device
that activates a microswitch. If the temperature at
the sensor bulb exceeds the pre-set value,
terminals 1 and 4 are opened. If there is a rupture
or break in the sensor tube (leakage), then the
switch remains permanently open (fail-safe).
If the temperature falls below the minimum setting, the autocontrol opens the circuit but closes
again on temperature rise.
Application example
The STW thermostat can directly switch
temperature-dependent equipment loads (heaters
etc.) of up to 5 A. Higher rated currents can be
switched by means of a contactor; the STW
switches the contactor coil. If an interlock is
installed by means of an additional relay (according to DIN VDE 0116), the STW can also be used
as a limiter.

Description
BSTW II 25-A Ex temperature monitors and BTB II/BSTB II temperature limiters are two-state controllers in
Ex e-certified polyester enclosures.
In addition to the use of conventional wiring by means of a sheathed cable, the BSTW II and BTB II/BSTW II
are suitable and approved for the direct connection of self-limiting BARTEC heating systems in the enclosure.
As a result, a verification of thermal safety and a further acceptance test by a capable person is no longer
necessary.
The benefit for the customer is obvious. The direct connection of self-limiting heating tapes does away with
the need for junction boxes and considerably reduces the extent of wiring required.
BSTW II and BTB II/BSTB II can monitor the ambient temperature but also the different surface temperatures.
In conformance to EN 60079-30-1, the BTB II and BSTB II fail-safe temperature limiters are designed to
switch off and remain switched off when the preset limit temperature is reached. The restart lockout requires
manual resetting directly in the device.
03-0330-0712-01/2014-BEH-346644/1
Function
Any change in temperature in the sensor causes a change in the volume in the liquid-filled measuring system, which in turn results in a movement of the diaphragm membrane, which is connected to a transmission
mechanism, and this opens a microswitch.
If the sensor temperature exceeds the set value, the contacts 1 and 2 remain continuously open. The contacts
in the BTB II/BSTB II remain continuously open until there is a manual intervention.

Heaters, fans, motors and other equipment are
energised and de-energised by means of this
thermostat when specific temperature ranges are
exceeded.
These devices can also be used to control the
temperature in air or on various surfaces. The
fail-safe temperature limiter BTB and the fail-safe
temperature limiter BSTB are produced with restart
lockout, resetting (reopening) is only possible at
the device.
Function
Any change in temperature at the sensor bulb
causes a change in the volume of fluid in the
measuring system, which in turn results in a
movement of the diaphragm membrane. This
membrane is connected to a mechanical device
that activates a microswitch.
If the temperature at the sensor bulb exceeds the
pre-set value, terminals 1 and 4 are opened.

The BTB and BSTB devices ‘lock-out’ permanently if the set temperature is exceeded. After a
temperature decrease of about 9 % below the set
value, both BTB and BSTB can be re-set manually. If there is a rupture or break in the sensor
tube (leakage), then the switch remains
permanently open (fail-safe). If the temperature
falls below the minimum setting, the autocontrol
opens the circuit but closes again on temperature
rise.

Features
 22 A switching capacity
 Can be used directly in Zone 1 and 2
 Direct heating circuit connection
 Flame-proof enclosure
 ATEX, UL, CSA, FM Approval
Description
The flame-proof encapsulated temperature
controllers/limiters (DTW/DTB) are designed for
(trace)-heating applications in the Ex area. They
can be used both for protection against frost and
for maintenance temperature applications.
Heating units and other operating equipment are
switched on and off by means of the temperature
controller when the temperature is too high or too
low.
The DTB temperature limiter is designed with
resetting lockout; resetting (restarting) is only
possible on the device.
Can be used for monitoring temperature in the
air or on surfaces.
Function
A change in temperature in the sensor causes a
change in volume in the fluid filled in the
measuring system, which in turn results in a
movement of a membrane, which is connected to
transmission mechanics and activates a
microswitch. If the sensor temperature exceeds
the pre-set level, the contact is actuated.
03-0330-0529-04/09-BEH-291057/1
The temperature limiter switches off permanently
if the temperature is exceeded. Once the
temperature drops, the temperature limiter can be
unlocked manually.
If there is a break in the measuring system
(leakage), the circuit remains open permanently.
Application example
DTW and DTB switch temperature-dependent
equipment (heating units) of up to 22/16 A
directly. Higher switching currents or 3-phase
applications are switched by means of a contactor.

Description
A complete solution for DEPU tubular steam trace

for use in potentially explosive areas.
Structure
All functional units are integrated in a standard
casing of aluminium. The connecting lines up to
6 mm 2 are contacted with cage tension spring
clamps.
Function
The controller is designed as a two point
controller and measures the temperature by
means of a Pt100.
The limiter works as an independent system and
measures the temperature at the hot spot with its
own Pt100. If the temperature exceeds the limit
value the limiter interrupts the heater permanently
and a fault signal is given.

All fault alarms are indicated by a master fault
contact. Resetting can be carried out directly on
the unit or externally with a key.
The power setpoint adjuster works as a fault-free
full wave control by means of a semi-conductor
relay.
A 7-segment display guarantees good readability
of the temperature values of controller and limiter
through the viewing plate.

The new DPCfront temperature control device series
currently consists of three standardised
temperature control devices that are adapted to
the (trace) heating applications.
Thanks to the use of a dual display the two
important temperature readings (setpoint and
actual value) can be seen at a glance. At the touch
of a button, the regulation’s output power is
displayed. This function allows an evaluation of
the heating circuit quality.
The control devices can function as two-point
ON/OFF control devices or PID control devices. If
desired, the autotuning function in all devices will
automatically determine the optimum (PID)
adjusting parameters for the control path. In all
models the regulation can be switched off for
maintenance work by pressing a button.
On account of the wide-range voltage input the
devices can be used almost everywhere in the
world.
Assembly
The control device is fitted into the front panel.
The compact dimensions of the front (48 x
48 mm) allow a space-saving control cabinet
design. The electrical connection is set up through
terminal screws on the rear.
Function
Temperature alterations in the sensor being used
are evaluated in the DPC front and shown as
temperature readings on the top LED display.
If the reading falls short of or exceeds the
temperature value that can be seen in the bottom
LED display, the output being used will
automatically switch itself on or off or set the
manipulated variable to the required value. To
monitor the temperature, a high & low alarm
function is pre-programmed.
The devices detect malfunctioning at the sensor
and in the control circuit and report these as
faults. Each type of alarm is signalled as a group
alarm via a relay.

DPC III Monitor
Description
Function
The new DPC III temperature controller series
currently consists of several standardised
temperature controllers which are suited to (trace)
heating applications.
Changes in temperature in the Pt100 sensor are
evaluated in the DPC III and are visible as
temperature readings on the LED display. If a
deviation from the preset level is detected, the
device regulates the heating circuit of the trace
heating in accordance with the pre-selected control
characteristic (ON/OFF or PID).
The Digital Controller monitors measuring circuits
for sensor failures, interruption or short circuit
and under-range and over-range measurements
in order to ensure process reliability.
The DPC III can be used universally as an ON/OFF
(two-position) or PID controller. The integrated
power pack with wide-range voltage allows the
devices to be used practically anywhere in the
world.
Assembly
Like the predecessor model DPC, the DPC III is
integrated in a snap-on housing for TS 35 DIN rail
mounting. Pt100 resistance thermometers and
thermocouples are connected at the measuring input.
The controller is equipped with a 16 A load relay
for two-position control, an 8 A group error
message relay, a logical voltage output for the PID
control and two settable digital inputs.
The voltage for the controller is supplied through
an integrated power pack with wide-range voltage.
The electrical connection is established with
terminal screws operating on the screw cage clamp
principle. The DPC III Controller is completely
downwardly compatible with the previous DPC
Controller.

An auto-tuning function is available for the PID
control and this analyses the control path (heating
circuit) and automatically determines and saves
the PID control parameters. The control’s output
power can be displayed at the touch of a button.
One of the benefits of this function is the possibility
of evaluating the quality of the heating circuit.
There are more factory-fitted switching points for
use as alarms for too-high or too-low temperatures.
When servicing the heating circuit, the control
output can be switched off at the touch of a button
on the device or through digital input and there is
the option of disabling the temperature alarms.
The process reliability is further enhanced by the
control circuit’s additional monitoring functions
and the connected measurement sensor. The
programming interface allows the device
parameters to be read out with a code key and
transferred to other controllers.
For effective parameter protection a multi-stage
password management system can be activated.
Furthermore, the manual control or soft start
functions can be activated for the system start-up.

DTL III Ex
 In conjunction with Pt100 Ex, it can be used
for monitoring temperature in explosionprotected heating circuits
Description
The new DTL III Ex digital temperature limiter,
which is adapted to (trace) heating applications,
serves to monitor heating and heating circuits.
The device is installed in the non-hazardous area.
The heating or heating circuits can be installed
both in media-protected and also in hazardous
areas.
Thanks to their integrated power supply unit with
wide-range voltage, the devices can be used
almost everywhere in the world.
Function
If the temperature at the Pt100 exceeds the set
limit value, the DTL II Ex permanently interrupts
the normally closed 16 A switch contact. This
situation is detected by a volt-free alarm contact
(change-over contact) and passes on the signal
to the control panel. After a temperature drop of
5 K below the limit set point, or after a fault has
been remedied, the limiter can be re-activated by
means of a re-set button on the device itself or via
a remote re-set control. The DTL will also interrupt
the switch contact in the event of a sensor open or
short circuit.
Process reliability is increased by additional
monitoring functions such as supply voltage
Circuit diagram
monitoring, pre-alarm, measuring circuit
monitoring for sensor break, interruption and
short-circuit as well as undershooting/
overshooting of the measuring range.
A multi-stage password management is available
for effective parameter protection. When doing
service work on the heating circuit, the load output
can be turned off by means of a digital input and
the temperature alarms can be disabled.
Using the programming interface, the device
parameters can be read out with a programming
key and transmitted to other devices.
Structure
The DTL III Ex is integrated in a latch-on enclosure
for TS 35 mounting rails. The alarm relay is
produced as a change-over contact and the limit
relay as a normally open contact.
The voltage is supplied to the control device
through an integrated power supply unit with
wide-range voltage. The electrical connection is
established with terminal screws operating on the
screw cage clamp principle, ensuring a safe
connection that is gentle on conductors.

Description
Technical data
This Pt100 Ex sheathed resistance thermometer
has been particularly designed for use in potentially
explosive areas. As it meets the requirements of
the EEx m type of protection, intrinsically safe
circuits can be dispensed with. Thanks to the
pliable part of the resistance thermometer, the
device is excellently suitable for application areas
requiring a high degree of flexibility and
replaceability (e.g. chemical and power plants).
Features
 Very fast response time
 Compact dimensions, compact design
 Extensive temperature range
Structure
The resistance thermometer is made of a 3 mm
thick light plastic-sheathed cable with different
lengths. This light plastic-sheathed cable is filled
with magnesium oxide.
The pliable part of the resistance thermometer
starts after 50 mm. Via a transition gland, the
connection to a flexible supply cable is created.

Electrical connection 3-wire

Function
Metals increase the electrical resistance with rising
temperatures. The platinum element of the
resistance thermometer has a resistance of
100 Ω at 0 °C. This characteristic is used for this
type of resistance thermometers to get an image of
the temperature. The resistance changes of the
Pt 100 Ex are converted into a temperature value
and displayed by a control unit.
