IKA STARVISC 200-2.5 control 0025003604 [7/26] Commissioning

Accessories must be assembled according to the

following assem-

bly instructions (Fig. 2 to

Fig. 7).

If above conditions are met, the device is

ready for operation after plugging in the

mains plug.

Speed – overload operation

In order to overcome peaks in the load such as arise when a solid

or viscous medium is added, the stirrer can be run for a brief pe-

riod at twice its rated power. When running in the overload range

(for instance if the viscosity has increased at a particular stage of

the process) the speed will be reduced to a degree sucient to

keep the torque on the stirrer shaft within the rated torque of the

device.

The speed is continually adjusted whilst the stirrer is running to

correspond to the operating conditions and so that it matches the

set speed as closely as possible.

Overload status 1:

The device is already running within the overload range, whereby

the actual speed does not match the set speed. This condition is

maintained as long as neither the motor current nor the tempera-

ture exceeds their permissible limit value.

This is indicated by the torque value ﬂashing in the display.

Once the load reduces to a value within the normal range again,

the torque value ceases to ﬂash.

Overload status 2:

If the device is subjected to a ﬂuctuating load which causes the

torque to be more than double the normal torque, the actual

speed of the stirrer shaft is quickly reduced to zero.

Message in the display: Error 4 (see “Error codes” section).

Output shaft

The clamping chuck and output shaft permit clamping IKA recom-

mend stirrer tools (see section “Permitted IKA stirrer tools“).

For safety reason, the stirrer cover must be pushed back into the

opening of the housing so that it is properly closed. This is the only

way to ensure that working with the unit is safe and that media

cannot enter the device.

Speed display

The speed is set using the rotary knob (B, see Fig.1) on the front

of the WiCo.

Commissioning

Assemble the overhead stirrer and all necessary accessories on a

stable, even, non-slip surface. The overhead stirrer must be secured

to a stable stand (e.g. R 2722 or R 2723) with a cross-sleeve (e.g.

R 270). The stirring vessel must always be securely ﬁxed for safety

reasons. You must also ensure that the mounting device (stand) is

set up in such a way that it is not liable to topple and does not start

to move during the stirring procedure.

Securing

Securing the extension arm to the overhead stirrer

Diagram (see Fig. 2)

Ensure that the extension arm is ﬁtted securely.

Vibration may cause the screw to become loose. It is therefore

necessary for safe use to occasionally check that the extension

arm is attached securely. Tighten the hexagonal socket screw as

required.

Securing the overhead stirrer to the stand

Diagram (see Fig. 3)

First secure the cross sleeve (H) to the stand (I). Then secure the

extension arm (J) of the overhead stirrer in the open side of the

cross sleeve which is facing upwards. Once you have set the po-

sition required for the stirring procedure, ﬁrmly tighten the two

clamping bolts (G).

Check that the stirrer is held in position ﬁrmly prior to each use and

also at regular intervals. The position of the stirrer must only be

adjusted when the equipment is stationary and the power supply

is disconnected.

Securing the stirring element using the chuck

Diagram (see Fig. 4)

Slide the stirring element (M) into the chuck (L). Tighten the chuck

ﬁrmly using the chuck key (K).

The stirring element must only be changed when the equipment is

stationary and the power supply is disconnected.

Securing the stirring shaft protector

Diagram (see Fig. 5)

Use a stirring shaft protector (Q), e.g. R 301, to provide protection

against injury when working with the device.

Use the bolts (U) to attach the plastic half-shell pieces to the stir-

rer (T), as shown in Fig. 5. The screw (S) can be used to adjust the

length of the stirring shaft protector.

Check that the stirring shaft protector is held in position securely

prior to each use and also at regular intervals. The position of the

stirring shaft protector must only be adjusted when the equipment

is stationary and the power supply is disconnected.

NOTICE

Please see section “Safety instructions“!

The speed is displayed directly in revolutions per minute (rpm) in

the display (C, see Fig.1) of the WiCo.
