3. Pre-Operational Procedures
This section contains the information required to carry out pre-operational procedures, and the checklist of items which
should always be reviewed prior to a production run.
DANGER: Before undertaking any machine repairs or maintenance, perform proper LOTO: always make certain
that the machine disconnect switch is turned to the OFF position or that the control enclosure is disconnected from the
main power source. Lockout all sources of power including the main disconnect switch and follow all of your plant lockout
procedures.
3.1 Electrical Test
Before applying power to the machine, have a qualified electrician check the incoming voltage in disconnect, and L1 to L3
(see electrical diagrams at the end of the manual for standard wiring diagram, or individual diagram for your specific
equipment packed with the machine). The voltage should be the same as indicated on the silver tag in the control
enclosure. If the voltage is not the same, contact the SEM service department for voltage modification instructions.
Once it has been determined that the voltages are correct, it is necessary to start the motors and check for the proper
direction of rotation.
1. Turn the main disconnect switch to the ON position.
2. Press the Disintegrator Start button to power the disintegrator motor. Visually compare the direction of motor shaft
rotation to the rotation arrow label (clockwise when viewed from the shaft end). If the motor turns in opposite
direction, reverse any two incoming power leads.
3. Once the rotation direction is correct, the remaining electrical controls need to be tested as follows:
• Press the Disintegrator Stop button and allow the machine to stop.
• For disintegrators equipped with conveyors, fans, etc., test their operation also by pressing the appropriate button.
Check fan outlet for proper airflow.
• For disintegrators with E-Stop buttons, test the buttons to ensure all motion stops.
• Loosen the hex coupling nut on the threaded swing bolts at the front of the machine to verify the safety interlock
switch shuts the machine off.
NOTE: If there is an access door on the hopper (for inspection or clean-out purposes) with a safety switch interlocked, make
certain that removal of the limit switch actuator bracket shuts the machine off.
