SAFETY

SECTION 1-9

Safety Clothing & Practices

TURN OFF AND LOCKOUT the power per OSHA 1910.147 OR ANSI Z244.1-1982 (Lockout/Tag-out of Energy Sources).

If it is not possible to lock out the power, have an electrician remove the fuses.

Make sure the rotor has come to a complete stop.

The hydraulic cylinders or jackscrews, which open the machine, should not operate until the rotor is completely stopped.

If you discover that the hydraulic cylinders or jackscrews DO operate while the rotor is still turning, immediately shut down the machine and call for maintenance to adjust it.

Wear gloves to protect against injury from the rotor or bed knives.

MACHINE OPENING DEVICES

The BP 2400 Series of granulators have been supplied with two different types of opening devices. These devices provide access to the Cutting Chamber for both the area above the rotor, mainly for cleaning/knife maintenance and below the rotor for cleaning/screen maintenance.

The system supplied on your machine may be either an electro-mechanical design (electric jackscrews) or of a hydraulic design (hydraulic cylinders & power supply). References to both systems appear throughout this manual. Be sure to follow the instructions that pertain to the system as supplied on your machine.

BE SURE THE ROTOR IS MOTIONLESS BEFORE OPENING MACHINE

Never open or remove any machine components unless the motor is electrically locked out and the rotor is completely motionless.

The BP 2400 Series machine has a zero speed sensor that detects motion of the rotor. This sensor is inter- locked to the controls of the two hydraulic cylinders or jackscrews. If it detects motion in the rotor, it cuts the power to the hydraulic cylinder/jackscrew controls.

If you ever notice that the hydraulic cylinders or jackscrews operate while the rotor is turning, have a mechanic and electrician check the speed sensor per the procedure in Section 4, entitled Zero Speed

Sensor.
