Switching On The Machine - IKA RW 16 basic Instrucciones De Manejo

Speed
The speed is set using the front knob(A). The scale from 1 to 10
corresponds to a speed range for the output shaft of 40 to 1200
rpm under nominal load. With no load the speed at maximum set-
ting of the knob (right position) is 1600 rpm, at minimum setting
of the knob (left position) 0 rpm. If viscosity increases due to the
process, the speed reduces gradually. If, however, the viscosity
is reduced by eg the addition of thinning agents, the speed increa-
ses somewhat. This can be balanced out in both cases by re-set-
ting the knob accordingly, provided torque does not exceed maxi-
mum torque. Please note that fluctuations in mains voltage wit-
hin the permitted tolerances may also cause minor fluctuations in
speed.
Commissioning
For correct use, the stirrer must be secured to a stable object
(eg R1822) with a cross-sleeve (eg R181). For safety reasons the
stirrer container should always be fixed with a tension-holder
(eg RH1).
Mounting the extension arm
For diagram see
The extension arm (X) has a step at its end with a cross hole. This
end is used to insert the extension arm into the hole on the back
of the machine. To do this, the cross hole in the extension arm
must point upwards. It must be brought into alignment with the
12
hole in the fixing rib on the back of the machine. To do this, press
the extension arm until it catches in the hole. Please do not use
force to do this. If it proves difficult to insert the extension arm,
light oiling may help. The hexagonal socket screw (Y) used for
fixing is inserted in the hole in the housing from above. The screw
is tightened using the hexagon socket offset screw key (Z).
Check that the extension arm is firmly seated. The screw may
loosen with vibration. Therefore as a precaution check from time
to time that the extension arm is still securely attached.
If necessary tighten the hexagonal socket screw.
You can also secure the hexagonal socket screw with adhesive,
but you are then unable to release the connection later .

Switching on the machine

Check whether the voltage given on the type plate corresponds
to the available mains voltage. The socket used must be earthed
(fitted with earth contact). If these conditions have been met, the
machine is ready to operate when the mains plug is plugged in.
If these conditions are not met, safe operation is not guaranteed
and the machine could be damaged.
The machine is started by pressing the mains switch (B) into
position "l". A green control light (C) signals the operating
condition "ON".
During commissioning of the machine the output shaft starts to
run at the last speed set. Therefore check the setting of the con-
trol knob. Also ensure that the speed set is suitable for the test
texture selected. If in doubt, set the speed knob (A) to the lowest
speed (left-hand position).
