4.7 Regular checks
The mortar mixer must be checked for industrial safety at regular intervals. There are
national regulations for this, which must be observed.
5. Description of the mortar mixer
5.1 Mechanical structure
The mortar mixer’s housing consists of a stable light metal casting.
The stirrer is made of stainless steel and is connected with the planetary gear by a
quick release fastener. It rotates on its own axis and is moved by an electric motor in a
planetary motion around the bowl axis at 2 fixed speeds.
The mixing bowl is made of NIROSTA steel and can be removed from the working posi-
tion after lowering.
The contours of the stirrer and mixing bowl match and guarantee a distance of 3.0 ± 1.0
mm between the mixing bowl and the stirrer.
This distance can be adjusted by loosening two clamping screws.
The electromechanical sand inlet is made of sheet steel. In the sand inlet’s housing
there is an electromagnet which moves the striker plate via a connecting rod. The striker
plate is kept shut by a spring and can be opened if the machine is switched off or oper-
ated at low speed.
5.2 Electrical structure
The supply voltage for the mixer must be 3 x 230 V + N + PE, 50 Hz.
The power is supplied by a 5-pin connector according to the CEE standard (the direc-
tion of rotation can be altered without opening the connector housing - see point 6.4).
The main switch, which disconnects the supply voltage of the mixer from all phases, is
situated on the mortar mixer’s right head side as seen from the front.
1) Components in the mortar mixer’s rear area
•I/O circuit board (on a fold-out assembly frame)
After folding out the assembly frame, the connecting terminals of the power supply ca-
ble and the fuses to protect the mixer against short circuiting are accessible.
2) Components in the mortar mixer’s head room
•Connecting terminals for the 3-pin main switch

Laboratory mortar mixer
1.0206.07

3) Display and control unit for the mortar mixer
•16 bit CPU, Hitachi H8 2646, 16 byte internal flash memory, 1 Kbyte RAM
•Display
•Multi-coloured signal lamps to indicate operational readiness
•8 function buttons
•Buzzer
•Unlockable emergency stop button
•Programming interface
The display and control unit is connected to the I/O board on the fold-out assembly
frame by a double-sided, pluggable, shielded control cable.
5.3 Safety devices
The mortar mixer is equipped with the following safety devices:
1. EMERGENCY STOP switch
The drive motor is disconnected from the mains power supply by the 3-pin safety
module when the EMERGENCY STOP switch is pressed.
To reactivate the control system, the EMERGENCY STOP switch must be
brought back to its home position again by rotating the switch in the direction of
the arrow.
2. Inductive, electronic proximity switch
The proximity switch in the mixing bowl mounting is energised by the mixing
bowl’s bottom flange and monitors its correct fit in the mounting.
If the mixing bowl is not inserted into the mounting, the safety module prevents
the mortar mixer from being operated. Acknowledgement via the display and con-
trol unit.
3. Inductive, electronic proximity switch
The proximity switch in the mixing bowl lifting device is energised on reaching the
mixing position and monitors the adherence to the correct mixing position.
If the mixing bowl is not in the mixing position, the safety module prevents the
mortar mixer from being operated. Acknowledgement via the display and control
unit.
4. Fixed protective cover
The mixing bowl is covered in the mixing position by a fixed protective cover
which encloses the stirrer on all sides.

6.7 Loosen and remove the mixer
Firmly grasp the mixer with the left hand and the mixer mounting’s knurled ring with the
right hand.
Loosen the knurled ring in an anti-clockwise direction until it can be shifted upwards.
Now pull out the stirrer in a downward direction.
6.8 Insert the stirrer and clamp securely
Insert the stirrer in the agitator head’s quick-action clamping release fastener with a
slight rotary movement until you feel it reach the end stop. Hold the stirrer with the left
hand and rotate the knurled ring until it falls downwards by approximately 10 mm. Now
clamp the knurled ring securely with the right hand by rotating it in a clockwise direction.
6.9 Insert the mixing bowl and clamp securely
The container carrier is in the lowered position. Grasp the mixing pot by the side han-
dles to insert it. The red arrow must point to the front. The mixing pot must now be in-
serted in such a way that both arrows attached to the mixing pot and the container car-
rier are aligned. Now tilt it slightly forward and let the mixing pot slide in effortlessly. The
mixing pot is tightened in a clockwise direction to lock.
6.10 Bring the mixer bowl into the mixing position
First swivel the hand lever to the right and then backwards as far as it will go and en-
gage it to the left.
The mixing bowl is locked into place in the mixing position.
6.11 Check the distance between the mixing bowl and the stirrer
Lower the mixing bowl and remove (see point 6.5), then loosen the stirrer and remove
(see point 6.6). The protective guard can now be removed from below by unscrewing
the 3 hexagon socket screws on the protective guard’s flange. Now reinsert the stirrer
and clamp securely (see point 6.7), also insert the mixing bowl and clamp securely (see
point 6.8), afterwards bring the mixer bowl into the mixing position (see point 6.9). With
the distance gauge (TESTING art. No.: 1.0203.07) the distance can be checked (EN
196-T1 3 ± 1 mm) and adjusted as described in point 6.11. If the distance conforms to
the standards, the protective guard is reassembled.

6.12 Set the distance between the mixing bowl and the stirrer
If the distance between the mixing bowl and the stirrer is greater than the applicable
standard allows for, this can be adjusted. The mixing bowl must first be lowered and
removed (see point 6.5). The two clamping
screws can now be loosened on the holder for
the mixing bowl by approximately 1 revolution.
Now loosen the lock nut of the adjusting screw at
the upper end of the mixing bowl holder, and
then set the distance with the help of the adjust-
ing screw from the mixing bowl mounting and
check with the distance gauge.
•By turning the adjusting screw in a clock-
wise direction, the distance is reduced.
•By turning the adjusting screw in an anti-
clockwise direction, the distance is in-
creased.
If the distance is set correctly, the lock nut, the
adjusting screw and both of the clamping screws
on the holder for the mixing bowl must be tight-
ened. The protective guard must be reassembled,
the mixing bowl and the stirrer must then be in-
serted.
