IKA T 65 digital ULTRA-TURRAX Mode D'emploi page 18

Mounting safety disconnection device:
There is a danger of trapping between the safety limit
switch, switch contact and the end stop!
Mount the SI 400 safety limit switch together with the SI 474
mounting support on the T 653 telescopic stand. Comply with
the "Safety limit switch" installation instructions.
Composition T 65 digital ULTRA-TURRAX
The control unit and the machine form a single unit. Operation
of the equipment is controlled by the controls on the frequency
inverter and the main switch.
The electrical terminal provided are for the:
- Power supply
- Power supply from the main switch to the frequency inverter
- Control wiring for the limit switch (optional)
Link to the supervisory control systems:
The equipment has an emergency stop safety cut-out. However
this applies only to the unit, not the supervisory control systems.
We have no knowledge of how links of this kind are configured;
therefore they can be implemented only by agreement and with
our express consent.
Mounting dispersing tool:
The unit may be operated only in conjunction with a Series S 65
shaft.
The dispersing shaft (2) must be inserted right up to the stop into
the coupling (1) on the unit and must be secured by tightening
of the rotary knob (3) finger tight.

The unit heats up in service. The generously-proportioned cool-
ing surfaces on the motor achieve an even distribution and emis-
sion of the heat.
With small quantities, a rapid heating-up of the medium
must be expected, because of the high motor power, which
is mainly converted into heat.
If the viscosity of the material to be processed is
too high (above about 5 Pas.), or the vapour pres-
sure of the liquid is very high, the flow is unable

to follow the rapid accelerations of the generator,
and breaks down. This leads to dry running, and
hence to destruction of the sealing surfaces of the
dispersing tool. Such substances must be fed to the
generator by force. Use a continuous flow unit (i.e.
IKA Laborpilot) for this, and/or an additional pump.

Switching on the device:
Check that the voltage stated on the rating plate
matches the available mains supply voltage. The
socket used must be earthed (protective earth
contact). If these condition are fulfilled, the unit is
ATTENTION!
ready for service, after the mains plug is inserted.
Otherwise, safe operation cannot be guaranteed,
or the unit can be damaged.
Before switching the unit on, the dispersion tool must be im-
mersed to the minimum immersion depth in the medium (see
operating instructions of the dispersing tool, chapter "Technical
data").
Because of the suction effect, the clearance to the base of the
vessel must not be less than 30 mm.
The dispersion tool must be brought into the vessel off-centre, to
avoid rotational turbulence (vortexing).
For safety's sake, the vessel must always be well secured.
ATTENTION! When operating with the SI 400 safety limit
switch, the unit is only ready for service when it has been locked
in position at the planned working height and the switch contact
operates the safety limit switch.
Switching on for the first time:
After the unit is switched on for the first time, the complete func-
tionality must be checked once again.
Switching the T 65 basic ULTRA-TURRAX
Start the unit by pressing the ON button (A).
Stop the unit by pressing the OFF button (B).
When the unit is switched on for the first time the direction of
rotation of the motor must be checked by briefly switching it on
and off. If the direction of rotation of the motor is incorrect, the
direction of rotation of the field must be corrected by a suitably
qualified person. The direction of rotation is indicated by the ar-
row symbol on the motor casing.
