Help
: Open electrical box and restore thermal protection QM4 by suitable lever. Push
alarms reset button and check surge tank motor operation.
To reset the alarms push the button - ALARM RESET - on display.
7.4. Functional stop of separator
Follow this procedure:
•
Close buttermilk shutter to take out of the bowl the residual cream.
•
Perform “chemical cleaning” of the separator (§ 8.4).
1)
Push the PUMP STOP button on the display (this button take electric energy off to product
feeding pump).
2)
Push the SEPARATOR MOTOR STOP black button (SB2) on electric panel (this button cut
out the electric power to the motor but leaves tension in power circuit), and push start cycle ,
stop cycle will appear.
3)
Cut out electric power to control panel turning the DISCONNECTION INTERRUPTER
(QS1) and wait about 55
60 min for the bowl stop.
4)
To reduce the machine stop time, use the brake and rotate counterclockwise the brake hand-
wheel (stop time = 7
10 min).
ATTENTION
Generic danger
The BRAKE must be used ONLY after the MOTOR has been electrically CUT.
7.5. Emergency stop
On electric panel (fig. 7.1) there is the
typical red-yellow mushroom head emergency button
;
pushing it the electrical feeding to separator motor and pump motor is cutting out; this assure
the machine stop in every operating condition (independently from the PLC).
7.6. Energy sources disconnection
ELECTRIC ENERGY
The main switch (QS1) on the electric panel (door interlock) permits disconnection of the
electrical supply. The switch can be lock to be sure of more security.
PNEUMATIC ENERGY
The user must predispose before the plant an on-off valve and must allow the compressed air
cutting.
HYDRAULIC ENERGY
The user must predispose before the plant an on-off valve and must allow the operating water
cutting.
7.7. Preliminary checks
• The bowl must be correctly assembled: the locking rings must be screwed right down (left-
hand threaded) and the marks “O” of the corresponding parts must be aligned.
• All the fixed protection (cover, ports, etc.) must be in right position.
• Verify that inlet-outlet flow unit and cover are well fixed.
