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 coo-
ling 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 genera-
tor, 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.
