IKA RH basic 2 Betriebsanleitung Seite 7

Risk of burns! Exercise caution when touching parts of the housing and
the heating plate. The heating plate can reach dangerous temperatures.
Pay attention to the residual heat on the heating plate after switching off
the stirrer.
The device may only be transported when the heating plate has cooled
down.
› Please consider any possible contaminations and unwanted chemical reactions.
› Before placing the device in service, please ensure that the turn dial for
adjusting the speed is against the left stop, since the device will begin to run
at the last speed that was set.
› The device will automatically restart following any interruption to the power
supply.
› The device may not be transported by using an H 16 V support rod or the
power cable.
› Clicking noises may occur as a result of material expansion during heating and
cooling.
› In unsupervised and safe operation, this device may only handle or heat media
whose flash point is above the set safety temperature limit. (acc. to EN 61010-
2-010)
› Follow the safety instructions, guidelines, occupational health and safety and
accident prevention regulations.
› The device may only be opened by qualified and IKA approved experts.
› Safe operation is guaranteed only with the use of original IKA accessories.
Intended use
Use
› The IKA RH basic 2; RH basic KT/C or the IKA RH digital KT/C is a stirring
instrument with heating function. The instrument is suitable for tempering
substances which are placed on the heating plate in vessels. By means of a
built-in stirring drive and with the help of a magnetic bar within the vessel, the
12
substances can be stirred at the same time. The mixing intensity is dependent
on the motor speed and on the size of the magnetic bar. The RH basic KT/
C and RH digital KT/C also has a contact thermometer connection and an
adjustable safety circuit.
Area of use
› Indoor environments similar to that a laboratory of research, teaching, trade or
industry area.
› The safety of the user cannot be guaranteed:
- if the device is operated with accessories that are not supplied or
recommended by the manufacturer,
- if the device is operated improperly or contrary to the manufacture's
specifications,
- if the device or the printed circuit board are modified by third parties.
Unpacking
Unpacking
› Unpack the device carefully. Any damage should immediately be reported to
the carrier (mail, rail or freight forwarding company).
Scope of delivery
› An RH basic 2 or RH basic KT/C or RH digital KT/C
› Operating instructions.
Commissioning
Check whether the voltage specified on the type plate matches the mains
voltage available. The power socket used must be earthed (protective earth
conductor contact). Before tuning on the machine, adjust the turn dial for
controlling the speed so that it is against the left stop. If these conditions are
met, the device is ready to operate after plugging in the mains plug. If these
procedures are not followed, safe operation cannot be guaranteed and/or the
equipment may be damaged.
Observe the ambient conditions (temperature, humidity, etc.) listed under
Technical Data.
Starting
The heating and stirring features can be turned on and off by pressing the unit
switch (A).
Version RH basic 2 and RH basic KT/C: The ready for operation and turned on
states of the device are indicated by the green lamp in the unit switch lighting
up.
Version RH digital KT/C: When you switch on the stirrer it will run a self-test and
all the LED segments of the displays will light up for a few seconds. After this,
the LED's (D; G) light up to indicate that the unit is powered up and ready for
operation.
Function Stirring
The stirring rod in the glass beaker with a maximum length of 60 mm is driven
by a permanent magnet located directly under the placing and heating surface. It
allows magnetic field lines to pass trough it. The permanent magnet is fastened
directly onto the drive shaft of the motor.
The actual speed depends on the load and voltage. Note that fluctuations in
the in the mains power voltage within the allowable tolerance and changes in
viscosity of the materials to be stirred resulting from processes they undergo may
also cause minor fluctuations in the speed.
Version RH basic 2 and RH basic KT/C: The speed of the motor can be adjusted
