GENERAL INFORMATION
Read the instruction manual with care and ensure that all users read it
with care prior to using the instrument.
Please store the instruction manual in a place easily accessible to every
user.
A EURO AC plug (DIN 49441 CEE 7/VII 10/ 16 A 250 V) is standard on all
instruments.
For North America, instruments feature standard US plugs
(NEMA Pub. No. WDI.1961 ASA C 73.1 . 1961 page 8 15A 125V).
When operating the instrument in countries with different AC plug
systems, use an approved adapter or have a qualified electrician replace
the AC plug with an approved model suitable for the country of operation.
The instrument is earthed as supplied. When replacing the original AC
plug, ensure that the earth conductor is connected to the new plug.

SAFETY INFORMATION
Please comply with all safety and accident-prevention regulations
applicable to laboratory work.
Use great caution when working with flammable substances. Observe the
relevant safety data sheets.
When connecting the instrument to an AC power outlet, ensure that your
local supply voltage matches that indicated on the instrument's rating
plate.
Turn the rocker switch off when not using the instrument and before
disconnecting it from its AC power outlet.
#Repairs may only be performed by technicians authorised by Heidolph
Instruments.
Use great caution when working in the vicinity of highly flammable or
explosive substances.
The instrument is not explosion-proof.
Always connect the instrument to an earthed AC power outlet.
Caution! Hazard of serious burns when running with hotplate over 50 °C.
Avoid contact with the hotplate, heating bath and liquid.
Caution!
When heating flammable substances, ensure that the nominal temperature
of the hotplate is at least 25 °C lower than the substance's flashpoint.
Caution!
Beware of the effect of the magnetic field on cardiac pacemakers and data
media.
Ensure that the instrument is standing on a solid surface.

E
INTENDED USE
The Hei-Standard is a safety magnetic stirrer with a heating function suitable for
unattended use. It is designed for use in chemical and biological laboratories of industrial
enterprises, universities, schools and pharmacies.
The instrument is designed to heat substances to a specified temperature and/or mix them
through the action of a magnetically linked stirring rod in a vessel.
To ensure maximum service life, observe the specified ambient conditions (temperature
and humidity) and ensure that the instrument is not exposed to a corrosive atmosphere.
SAFETY INSTALLATION ON THE DEVICE
Function of the safety switching-off facility:
2 independent, temperature-measuring sensors are located in the hotplate. One serves
the processor-driven control of the hotplate. The other serves the analog safety circuit
switching off all the poles.
Criteria for the safety switching-off function (heating and agitation OFF):
¾The temperature set for the hotplate (reference value) is exceeded by 50°C
¾The measured temperature of the hotplate (actual value) is higher than 360°C
¾Sensor breakage or short circuit in the temperature sensor of the safety circuit
¾Sensor breakage or short circuit in the temperature sensor of the control circuit
¾The µ-controller is affected in the program sequence
SET-UP
1 Unpacking
Unpack the instrument with care. Inspect for damage and report such damage or missing
parts to your supplier right away.
2 Setting up the instrument
Place the instrument on a solid, horizontal surface. Keep the area around the instrument
clear of other items.
22
E
3 Electrical connection
Before connecting the instrument to
an AC power outlet, ensure that the
rocker switch (A) is set to "0".
Plug the AC power cord into its socket (H) on
the rear panel. Connect the power cord to an
AC power outlet.
4 Connecting an electronic contact thermometer Hei-Con
The Hei-Con and Hei-Con-G permit the
temperature of the medium to be controlled in
addition to that of the hotplate.
Connect the Hei-Con to the socket (I) on the
rear panel of the instrument. For more
information, please refer to the instruction
manual of the Hei-Con.
Rule of thumb:
Set the temperature of the hotplate to around 1½ to 4 times that of the
desired set temperature on the Hei-Con. This will compensate for the
loss of heat between the hotplate and the medium.
23
E
5 Connecting a contact thermometer in accordance with DIN 12878
Contact thermometers permit the temperature of the medium to be controlled in addition to
that of the hotplate.
Note:
We recommend the use of a safety contact thermometer when using the
instrument with a contact thermometer.
Pin assignment for safety contact
thermometer in accordance with
DIN 12878
Connect a 4-pin diode plug conforming to
DIN 41524 to the contact thermometer.
Refer to the drawing for the pin assignment.
Pin assignment for contact thermometer
without safety features
When using a contact thermometer
without glass breakage safety features,
bridge pins 5 and 3.
Connect the
contact
thermometer to
the socket (I) on
the rear panel of
the instrument.
Remove the
jumper plug (J).
The following accessories are available for use with a contact
thermometer or a Hei-Con:
X: Holder for thermometer or temperature sensor
(order no.: 509-67000-00)
Y: Holder rod (order no.: 509-81000-00)
Z: Hei-Con (order no.: 509-88000-00) or
Hei-Con-G (order no.: 509-88100-00)

6 Using a heating bath
When using the instrument with a heating
bath (see Accessories), ensure that the
positioning rim on the heating bath is fitted
securely over the hotplate.
When using the 4l heating bath, a special
temperature sensor holder rod for 4l
heating baths (order no. 509-97000-00)
may be attached as shown (W).
OPERATION
7 Switching the instrument on
Caution:
Heating and stirring will begin immediately after the instrument is
switched on in accordance with the settings of control knobs (B) and (C).
Hotplate is hot! Agitator will begin turning immediately!
Danger of burns and splashing.
Before switching the unit on, turn control knobs (C) and (B) fully to the
left.
Turn on the instrument's power using
the rocker switch (A) on the right side
of the housing. The green Power
LED (G) on the front panel will light.
25
E
8 Setting the stirring speed
Set the desired speed with the control
knob (B) according to the scale.
The motor will start when the speed is set
to 100 rpm or higher.
9 Heating without external contact thermometer
Use the control knob (C) to adjust the set temperature for the hotplate. The temperature
can range from room temperature to 300 °C according to the scale. The heater will be
activated when a temperature higher than 20 °C is set. The LED (D) is lit.
The LED (D) flashes when the heater is active.
Note:
The jumper plug (J) must be in place. The instrument will not heat
otherwise.
Notes on setting the hotplate temperature:
The contents of the mixing vessel will always have a lower temperature
than the set hotplate temperature due to differences in heat conductivity
of various mixing vessels, the volume of material to be heated, and heat
loss due to radiation.
As a rule of thumb, the hotplate temperature should be 1.5 to 4 times
that of the desired temperature of the medium.
The value should be increased according to the specific heat capacity,
volume and desired temperature of the medium.
Note
Note on heating time:
Higher hotplate temperatures will result in a shorter heat-up period.
