Pressing the +/- buttons (H or I) increases or reduces the
temperature.
RT
The heating function is started and stopped by pressing the
„Temp“ button (J).
Function Heating
ECO mode
RO/RT
The heat generated in the device can be reduced by lowering the
power of the input coils.
Pressing the “ECO Mode“ (F) key to reduce the current power
setting. ECO mode is indicated by an “E” preceding the speed.
When the power is set to ECO mode, the speed is limited to 600
rpm.
To make the stirring power more independent from the speed
range, press the “ECO Mode“ membrane key (F) and then select
one of the following setting options.
P50 (Stirring power 50% independent of the speed range)
P75 (Stirring power 75% independent of the speed range)
P100 (Stirring power 100% independent of the speed range)
---- (Standard stirring performance with the stirring power
regulated by the speed)
RO/RT
The (G) key activates the “Reverse Rotation” function.
When the „Reverse Rotation“ function is switched on, a decimal
point (K) appears in the LCD display.
The running time (30, 60, 90 or 120sec) is set by pressing the (G)
key followed by the +/- keys.
After the preset running time, the drive is switched off and
restarted at minimum speed in the opposite direction after a
pause specific to the speed.
In this way the magnetic rod is captured and any liquid still
rotating is gradually slowed down. Then the drive accelerates to
the target speed.
Note: If the “Reverse Rotation” key (G) is pressed again, the drive
will keep rotating in the same direction.
When the device is started up again, the drive will rotate in the
direction last set.

RO/RT
To toggle between modes, press the Start/Stop key (C) when
switching on.
Operating Mode “A”
All the parameter settings are retained when the device is
switched off or disconnected from the mains.
The “Start/Stop” (C) key starts the device with the set parameters.
Operating Mode “B“
All parameter settings, including “Start/Stop”, are saved when the
device is switched off.
Operating Mode “D“
In the D mode the device operates as per the A mode but with the
following exception:
- Switch on and then press the “Temp” membrane key to confirm
the safety temperature.
- The value flashes until it is confirmed.
Factory setting: mode A
Operating modes
The equipment is maintenance-free. It is only subject to the natu-
ral wear and tear of components and their statistical failure rate.
Cleaning
- For cleaning disconnect the mains plug!
- Use only cleaning agents which have been approved by IKA to
clean the devices:
These are: water (containing surfactant) and isopropyl alcohol.
Maintenance and cleaning
- Wear protective gloves during cleaning the devices.
- Electrical devices may not be placed in the cleansing agent for
the purpose of cleaning.
- Do not allow moisture to get into the device when cleaning.
- Before using another than the recommended method for
cleaning or decontamination, the user must ascertain with IKA
that this method does not destroy the device.
