GENERAL INFORMATION
Unpack your item carefully.
Inspect for damage and report such damage or missing parts to your supplier right away.
Read your instruction manual carefully. Take time to save time while working with your item.
Make sure that every user has read and understood the instruction manual.
Please store the instruction manual in a place easily accessible to every user.
IF ALL ELSE FAILS, READ THESE INSTRUCTIONS !
A so called EURO- plug (DIN 49441 CEE 7/VII 10/ 16 A 250 V) is standard on all of the items.
For the Continental US they feature a US-standard plug (NEMA pub.no.WDI.1961 ASA C
73.1.1961 page 8 15A 125V).
When using the item in a country with deviating outlet / plug systems, we recommend to use
approved adapters or to have an electrician replace the standard plug with one suiting your
needs.
As shipped, the item features a protective ground wire. When replacing the original plug, make
sure to re-connect this protective ground wire in the new plug !
SAFETY INFORMATION
Please comply with all safety and accident-prevention regulations as in force for laboratory work !
Use extra care when working with flammable substances; refer to safety data sheets.
When connecting your item with your local power supply, please make sure your item is
designed for your local supply voltage; go by data plate on the item.
Turn your power switch OFF whenever the item is not used, or before disconnecting the
plug.
Repair work is restricted to technicians approved by Heidolph Instruments.
Use extra care when working in the vicinity of flammable and explosive substances. Motors are of non-sparking type, however, the item itself is not explosion proof
Please connect your magnetic stirrer with a protective-ground outlet only.
Caution! Hazard of serious burns when running the hot plate over 50 °C.
Avoid contact with hot plate, heating bath and fluid.
Caution! When heating flammable substances, adjust hot plate nominal temperature to a
lower level than the substance’s flashpoint.
Your item requires a solid stand.

Do the following checks before connecting:
• Power switch (1) OFF (position “0”). (When ON, the toggle switch lights GREEN)
• Connect item with mains by plugging the power cord in the plug connector (15) located in the
item’s rear panel and your outlet.

Connect external temperature sensor Pt 1000 (chromium steel- or glass sheath)
Turn item OFF attempting to connect the temperature sensor.
Connect sensor’s bayonet-type plug with flanged connector (16) in the
item’s rear panel
Please keep in mind that sensor needs an immersion depth of
not less than 20 mm (mark) to avoid false reading.
For Pt 1000 wiring, please refer to diagram below.
Item does accept a Pt 1000 temperature sensor only
(P/N 509-67910-00 or 509-67920-00); a Pt 100 won’t work.

Set-up using bath
If you are going to use a heating bath (refer to “Accessory“ section) make
sure bottom rim of your bath properly fits over the hot plate.
When using the item with a 4 liter bath accessory, you may attach the temperature sensor to a special stand (18) (P/N 509-98000-00) designed for the
4 liter heating bath.

Turning the power switch (1) ON (range I), a self-test is done; all LEDs (8, 11) light for a moment,
and all bars in the digital display (7) appear, display shows Set1, Set2 or Set3, followed by 3
beeps.
When power switch is ON, stirrer motor is ready to run.

alter temperature setting with rotary control (3).
Temperature setting will be accepted immediately, confirmed by a beep and “Act Temp“ appears
in the display.
Attempting to lower nominal temperature by an amount exceeding ∆T set will be
reported as error code F6.
Remedy: rise ∆T –value until system temperature has dropped to an acceptable
level.
25

3.2 Set safe temperature using ∆T (temperature difference)
Safe temperature is the total of temperature set plus ∆T (temperature cushion). Exceeding this safe
temperature will disconnect your magnetic stirrer for reasons of safety.

temperature setting with rotary control (3).
Temperature setting will be accepted immediately confirmed by a beep and “Act Temp“ appears
in the display.
3.3 Heating circuit ON / OFF
After having set speed, nominal temperature and ∆T, you may turn the heating circuit ON. At this point
you may double-check set values by hitting the Select key (5) several times. This way, Act Temp; Set
Temp; Set ∆T and Act Speed will appear in the display (7) one after the other.
• We recommend to select Act Temp display all the time.
• Hit the ON/OFF key (4) to turn the heating circuit ON.
• Heater LED (8) is going to light, i.e. system is heating.
• A yellow LED (9) confirms heating current ON.
• A soon as hot plate temperature exceeds 50°C with power switch or heating circuit at OFF, a
RED LED (10) will start to flash.
(also refer to para. 6, residual heat warning)
• Hit the ON/OFF key (4) to turn the heating circuit OFF.
All of the parameters previously set are saved by the built-in memory circuit and
are available at re-start.

E
4. Heat medium using 2-station temperature sensor (Set2 mode)
Connect 2-station temperature sensor as described in para. 3 “Set-up“.
For special applications, we recommend a 2-station temperature sensor (refer to picture). This sensor
allows to limit max. temperature of the medium to a certain ∆T from nominal and avoids temperature
overshoot in the medium close to the bath wall. For working with this temperature sensor, please refer to
the following details:
Safety cut-off feature (refer to para. 3.2 “set safe temperature“) is not active.
Heating time may rise at low ∆T.
Medium temperature overshoot might occur at high ∆T due to the inherent
thermal capacity of the heat carrier. If this happens, decrease ∆T.
•
•
Immerse a temperature sensor with white handle (A) (= marked medium) in the medium bath.
Immerse the second temperature sensor with black handle (B) (= marked heat transfer medium
or carrier) in the heat transfer medium.
Use one more holder for this temperature sensor (P/N 509-67000-00).

4.2 Setting 2-station temperature sensors
Set nominal temperature ∆T and turn the heating circuit ON as described under para. 3.1, 3.2 and 3.3.
Whenever you replace the 2-station temperature sensor with a “normal“ Pt 1000
sensor (chromium steel or glass sheath), change control mode to Set1 (refer to
para. 4.1 “select 2-station temperature sensor control mode“)
5. Heating in absence of temperature sensor (Set3 mode)
No temperature sensor connected will make the item control hot plate temperature only.
MR 3004 safety is designed as to auto-detect this operational mode (Set3 mode).

For setting hot plate nominal temperature please refer to para. 3.1 “set nominal temperature“.
Also refer to para. 3.3 “turn heating circuit ON/OFF“.
6. Residual heat indicator
To avoid burns when touching the hot plate, the MR 3004 safety features a residual heat indicator. A
flashing red LED (10) warns you that hot plate temperature still is above 50°C; this safety feature is
available only with the power switch or heater switch in OFF position.
