Coated glassware
• Coated glass components offer protection against the glass
splintering if it breaks under vacuum. Please note that when
coated glassware is used it is only to the condenser and receiving flask to which coating is applied.
• For operational reasons, the coating is not applied to the entire
area of the glass. In particular on the condenser there are areas
to which no coating is applied, especially at places where joints
and connections are made.
• Evaporating flasks with special heat-resistant coatings are available as accessories.
• The coating does not offer any protection against damage to
the glass or breakage of the glass.
• Do not use the glass component if its coating is damaged.
• The use of coated glassware does not release you from the obligation when the device is in use to enclose it on all sides with an
extractor hood or to employ an appropriate safety device.

Oil-tempered heating bath
• If silicone oil is used as a tempering medium, in the event that
the evaporating flask fractures there is a risk that on mixing with
the aqueous solvents (contents of the evaporating flask) the hot
oil will foam up and spurt out in conjunction with a rapid increase in volume (formation of bubbles by the solvent).
Note: Using high-viscosity oils or solid grease can lead to over-
heating in localized areas, causing excessive pressure to build up
in the bottom of the vessel.

With the button “Mode” (D) the correcting variable desired (set
temperature) can be preselected. The heating bath temperature of
the device is kept constant by the control circuit and is additionally
monitored by the safety circuit. In the event of a disturbance in
the control circuit, the heating bath is switched off permanently
by the safety circuit. In the event of a fault in the control circuit
or in the safety circuit, the LED “Temp.” flashes yellow and green
alternately. The LED next to the reset button lights up red.

When switching on the device the state of the heating and stirring
functions are taken over before the device was switched off last as
well as the last values set. The set values can be changed.

Control of medium temperature
The desired medium temperature can be set between 0 and 200
°C with the control knob (B), but not higher than the set safety
temperature. The value set can be read off on the digital display
(C) (Fig. 12). The heating function is switched on and off by pressing the button “Temp. On/Off” (F). If this function is activated the
green LED next to the lettering “Temp” lights up. The heating bath
is heated up to the set temperature. On the LCD display the set
temperature, actual temperature and the PV symbol are displayed.
The set temperature and actual temperature relate to the medium. During the heating phase the colour of the LED changes
between green and yellow. If the yellow LED lights up this means
that the heating system is being supplied with energy. If the heating function is switched off using the sensor key and the medium
has reached a temperature of above 50 °C the yellow LED flashes
(20% on 80% off).
On the LCD display °C and HOT are displayed alternately (Fig. 13
and 14). The temperature of the heating element is limited by the
safety temperature set. The medium temperature is controlled by
a fuzzy logic controller. The medium temperature is measured by
a PT 500 temperature sensor and is heated up as quickly as possible without overshooting to the set temperature. The fuzzy logic
controller automatically adapts to the various heat capacities of
the different heat transfer fluids. This guarantees an optimal temperature management without temperature drift and waviness.
Operation with external temperature sensor PT 1000.60/61 (only for HBR 4 control)
The supplied external temperature sensor PT 1000.60/61 can be
used as a setpoint transmitter for controlling the temperature of
media, by using a vessel (e.g. glass flask) which is immersed in the
water or oil bath.
The sensor tube must be of sucient length to be immersed in
the medium to be tempered (at least 20 mm) and fixed in position
on the vessel.
If the temperature sensor PT 1000.60/61 is connected to
the interface, the temperature regulation is automatically
controlled by the external sensor!
The temperature sensor PT 1000.60/61 is not intended to act as a
temperature sensor for the heating bath.
If the sensor is immersed directly in the heating bath (which is
considered misuse) and is at the bottom of the bath, control deviations of up to +/-4 K can occur.
An error message (Er 5) will appear if the sensor value of the external sensor does not change within a certain period of time (adjustable Error 5 response time 1 ... 30 min), e.g., because the sensor is
not immersed in the medium.
This detection is activated only at differences > 5 K between the sensor temperature and the target temperature,
when the sensor temperature remains constant (+/- 0.5 K).
Setting the response time of error 5:
When “Er 5” appears on the display, press and hold the button
“Mode” (D) and at the same time set the desired response time
(1...30 min) by turning the control knob (B) .
Note:
0 min (zero) means the monitoring is switched off (OFF)!
Stirring function
With the button ”Mode” (D) the correcting variable desired (set
speed) can be preselected. With the control knob (B) the desired
speed of the stirrer drive can be set between 0 and 800 rpm in
steps of 50 rpm. The value set can be read off on the digital display
(C) (Fig. 15).
The stirring function is switched on and off by pressing the button “Motor On/Off” (E). If this function is activated the green LED
lights up next to the lettering “Mot.“ The motor runs gently up to
the speed set. On the LCD display the set speed, actual speed and
the PV symbol are displayed (Fig. 16).
If both functions (heating and stirring) are switched off, the LCD
display always indicates the set temperature set. When the heating
function is switched on it is given priority on the LCD display.
If the stirring function is started with the sensor key or called up
using the button ”Mode” (D), the system switches over to speed
display for five seconds. With the button ”Mode” (D) the LCD display can be changed from temperature to speed and vice versa
at any time. After five seconds the system switches back to the
predominant mode.

Interfaces and outputs
The device can be operated in “Remote” mode via an RS 232 using
the laboratory software Labworldsoft
®
.
Note: Please comply with the system requirements together with
the operating instructions and help section included with the software.
Configuration
The RS 232 serial interface can be used to operate the device using
a computer and a suitable user program (Labworldsoft
®
).
In order to increase safety when operating the HBR 4 control
using a PC, a watchdog function can be activated which monitors
the continuous data flow (see section entitled: “Watchdog function”).
• The functions of the interface circuit between the laboratory de-
vice and the automation system are a selection from the signals
specified in the EIA standard RS 232 C as per DIN 66020 Part 1.
The assignment of the different signals can be seen in the image.
• Standard RS 232 C, corresponding to DIN 66259 Part 1 is valid
for the electronic characteristics of the interface circuits and assignment of signal states.
• Transmission process: asynchronous character transmission in
start-stop operation.
• Transmission type: full duplex
• Character format: character composition according to data for-
mat in DIN 66022 for start-stop operation. 1 start bit, 7 character bits, 1 parity bit (even), 1 stop bit.
• Transmission speed: 9600 bit/s
• Data flow control: hardware handshake
• Access method: data transmission from the device to the com-
puter only occurs after a request from the computer.
Command syntax
The following points should be noted for the instruction set:
• Commands are generally sent from the computer (master) to the
lab device (slave).
• The device sends only at the computer’s request. Even fault indications cannot be sent spontaneously from the device to the
computer (automation system).
• Commands and parameters, as well as consecutive parameters,
must be separated by at least one space (code: hex0x20).
• Each individual command (incl. parameters and data) and each
response are terminated with Blank CR LF (Code: hex 0x0D and
0x0A) and have a maximum length of 80 characters.
• The decimal separator in a number is a dot (Code: hex 0x2E).
The above details correspond as far as possible to the recommendations of the NAMUR working party (NAMUR recommendations
for the design of electrical plug connections for analogue and
digital signal transmission on individual items of laboratory control
equipment, rev. 1.1).
