GENERAL
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 product. 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 !
The EKT 3001 and 3001 G are electronic temperature controllers for liquids. Used together
with magnetic stirrers and heating appliances, they are designed to replace conventional
mercury contact thermometers in the laboratory.
The microprocessor controlled electronics is responsible for the control functions and ensures
high linearity and measuring accuracy. Integrated fuzzy control guarantees an optimum
heating-up speed without overshooting of the desired temperature.
Thanks to the flexible sensor/controller connection, it is possible to position the controller
away from the area at risk from heat and fumes.
The temperature controller is protected in several ways:
• Fuse for sensor short-circuiting
• Fuse for sensor breakage
• Safety and control circuit to DIN 12878 Class 1 and 2
During operation, the sensor and cable are checked constantly for interruptions and shortcircuiting.
If a fault is discovered, the heating is switched off and the fault indicated in the
display.
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.
The sensor comes into contact with hot liquids. Hold the sensor only by its
plastic grip.
Repair work is limited to technicians approved by Heidolph Instruments.
Use extra care when working in the vicinity of flammable and explosive substances.
The item itself is not explosion-protected.
18

E
Caution ! Hazard of serious burns when running the hot plate over 50°C.
Avoid contact with hot plate, tank and fluid.
Caution ! When heating flammable substances, adjust hot plate nominal
temperature to a lower level than the substance’s flashpoint.
Your item needs a solid stand.
SET-UP
1. Setting Up the EKT 3001
1.1. Fitting the holding rod
• Unscrew the black cap (1) and remove from
the top of the magnetic stirrer.
• Screw the holding rod (2) in the same hole.
1.2. Fitting the temperature controller
• Press the clip (4) into the holes on the back
of the EKT 3001 until it latches in place.
• Push the clip over the holding rod. (With Ø
10 mm, the tab (3) has to be folded over).
• Slide the bracket (6) onto the holding rod
(2). (The sensor bracket can be ordered as
an accessory).
• Fix in the correct position with the knurled
screw (5).
• Push the sensor (1) into the bracket (6)
from above or from the front.
19

E
1.3. Electrical connection
• Pull out the shorting plug (3).
• Insert the 5-pin plug (8) in the socket (7) on the back of the appliance.

1.4. Connecting to the Power Supply
If you use appliances other than the MR 3001 K, HG 3001 K or MR 3002
with the EKT 3001, make sure the switching function is correct.
The appliance needs a direct voltage of 9 – 12 V.
20

E
MR 3001 K, HG 3001 K, MR 3002
• If any of these appliances are used, the EKT 3001 will receive its power from them. In
this case you will have completed its power connection after carrying out Section 1.3
• Connect the magnetic stirrer or heating appliance to the power supply.
MR 2002 and other magnetic stirrers or heating appliances
For these appliances you will need a plug-in power pack. It can be ordered as an accessory
(order no. 14-012-007-39).
• Insert the jack plug of the plug-in power pack in the socket (8) of the EKT 3001.
• Connect the plug-in power pack to the power supply.
The EKT 3001 does not have a power switch. It is switched on and off via the power switch
of the magnetic stirrer. If a power pack is used, switch off by disconnecting the power pack
from the mains.

3. Operation
Immerse the sensor at least 20 mm in the liquid. Failure to do so could result
in measuring errors and overheating.
3.1. System Test
Immediately after switching on, all segments of the digital display
should be visible for 2 seconds.
This is followed by the measuring channel test. The value 38.8
(with a tolerance of +/-0.2) should be displayed for 2 seconds.
If the displayed value lies within the specified tolerance, the appliance is correctly calibrated.
If there is a bigger deviation, please return the appliance to the manufacturer for
calibration.
3.2. Temperature Measurement
After the system test described above, the first temperature
measurement will appear with the °C symbol. The EKT 3001 is
now ready to use.
22

E
3.3. Setting the Desired Value
press approx. 1 s
The display shows a preset value which you can change.
An “S“ (symbol for desired value) appears in the fourth position
from the right.
press briefly
The desired value of your choice can be set with the arrow
keys.
press and hold
Fast change mode: After 3 seconds the desired value is
changed in increments of 10.
press
The desired value is adopted; the actual value then returns to
the display.
If neither the SET key nor the ▲ or ▼ key is pressed within 15 seconds, the appliance will
return automatically to actual temperature display.
Heating control is switched off while the desired temperature is being set (symbol ”S”),
3.4. Control Behaviour
To prevent as far as possible any overshooting of the temperature when heating a quantity
of liquid, the EKT 3001 uses FUZZY logic for control optimization. The magnetic stirrer’s
heating is switched off before the desired temperature is reached so that the liquid is then
heated only with the residual heat in the hotplate.
To heat small quantities (< 500 ml): Set the temperature of the heating
plate to approx. double the value of the desired temperature. The maximum
temperature is to be used for large quantities only.
Desired values of over 150°C may be accompanied by a slight control deviation. This can
be compensated by setting a higher desired value.
23

E
3.5. Control Status Display
If the desired value is greater than the actual value, the heating
is switched on. The letter “h“ (symbol for heating) is then
displayed in the fourth position from the right. If the FUZZY
logic comes into operation and switches the heating off before
the desired temperature has been reached, the “h“ symbol will
disappear.
Modern magnetic stirrers have their own system for controlling the surface temperature of
the heating plate. This internal control system always has priority.
3.6. Max Value
press
The maximum temperature reached since the EKT 3001 was
switched on is displayed.
press
The stored MAX value is deleted.
press
The MAX value display is terminated.
If the MAX key is not pressed within 10 seconds, the appliance returns automatically to the
actual value display.
24

E
3.7. Range Monitoring
If the measuring range is overshot (+ 300 °C) the symbol “HI” will be displayed. If the
measuring range is undershot, the “Lo” symbol will be displayed.
3.8. Sensor Monitoring
If the sensor is interrupted, the symbol “HI” will be displayed. If the sensor short-circuits,
the symbol “Lo” will be displayed.
CLEANING & SERVICING
Cleaning: wipe housing surfaces clean with a damp cloth (add some sort of mild liquid
soap).
Note
To avoid damage to the surface finish, avoid using chlorine bleach, chlorine-based
detergents, abrasive substances, ammonia, rags or cleaning
agents containing metal particles.
The item is maintenance-free. Repair work is limited to technicians authorized or appointed
by Heidolph Instruments. Please call your local Heidolph Instruments Dealer or a
Heidolph Instruments Field Representative (also refer to page 28).
