Safe Shut-down
The following shut-down procedure is used to remove power from the MagneMover LITE
transport system in an orderly manner and place the components in known safe conditions.
This procedure is used to prepare the components for removal, replacement, or maintenance.
The MagneMover LITE transport system requires no special shut-down procedures. When
shutting down the host controller, the MM LITE components must be shut down first.
1. All material transfers must be completed (move all material to the appropriate loca-
tions).
2. Command all vehicles (pucks) to known safe positions.
3. Issue a Suspend Motion command for all paths.
All vehicles come to a controlled stop.
4. Once all motion has stopped, issue a Reset command for all paths.
The HLC clears all vehicle records.
5. Turn off all electrical power to the motors.
6. Turn off all pneumatic power to the precision locator option if installed.
7. Turn off power to the node controllers.
8. Turn off power to the host controller.
9. Turn off the main power disconnect for the MagneMover LITE transport system.
NOTE: This procedure only shuts down facilities to the MagneMover LITE motors, their
subsystems, and the host controller. Any user equipment remains powered up.
CAUTION
Electrical Hazard
The shut-down procedure is used in the normal shut-down of
the MagneMover LITE transport system. This procedure
removes the power source and all other facilities to the com-
ponents and provides guidelines for lockout/tagout. This pro-
cedure is NOT the same as an EMO circuit or other safety
interlock.
