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 ready for service, after the mains plug is inserted. Otherwi-
se, 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 ® unit on and off
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.

least a second for a command to be acknowledged.
- Slowly turn the "Speed setting" rotary knob (E) to the desired
setting. The actual speed appears on the display (F).
- Keep the "Stop" button (B) pressed for at least a second to stop
the unit. The unit starts up slowly. "rdy" (ready) appears again
on the display (F).
When slowing down, "dEC" (decrease) is displayed; after co-
ming to a stop "rdy" (ready) is displayed.
- In emergency actuate the "EMERGENCY STOP switch" by tur-
ning the "EMERGENCY STOP switch" rotary knob (A) anticlock-
