PC-Based Controller:
The user-supplied general-purpose computer that provides control and
sequencing for the operation of the transport system.
PE:
Protective Earth. A conductor that is provided for safety purposes (for exam-
ple, against the risk of electric shock) and which also provides a conductive
path to earth. See also,
.
Platooning:
A set of vehicles that are moving in a convoy and being controlled together.
This group of vehicles is allowed to maintain a distance between each other
while in motion that is less than the
PLC:
Position:
A specific location on a
, which is measured from the beginning of that
path, which is used as a vehicle destination. Position zero on any path is
defined as the leading edge of the first LSM in the path.
A vehicle at a specific position has its midpoint over that location on the path.
Power Supply:
The equipment that is used to convert facility AC power to the correct voltages
for the transport system.
Programmable Logic Controller:
The user-supplied dedicated controller consisting of Processor
and I/O modules that provide control, sequencing, and safety interlock logic
for the operation of the transport system.
Propulsion Power:
The power that is used for vehicle motion. See also,
Protected Area:
The area around a node that is defined by the entry gates and clearance dis-
tances. This area is used to make sure that vehicles do not collide with other
vehicles in the node or with the mechanism that is related to the node.
Puck:
A preconfigured vehicle for use on MagneMover LITE transport systems. The
magnet array is mounted to the puck and interacts with the motors, which
move each vehicle independently. See
.
QS:
QuickStick:
A MagneMotion linear synchronous motor that enables quick, efficient con-
veyance of large loads on user-designed guideways and vehicles. QuickStick
100 (QS 100) motors move loads up to 100 kg [220 lb] per vehicle. QuickStick
High Thrust (QSHT) motors move loads up to 4,500 kg [9,900 lb] per vehicle.
QuickStick System:
A group of specific components that contribute to a
. These
motors,
,
(QSHT only),
, and other parts available from MagneMotion.
Sensor Map:
A snapshot of the signal state of vehicle magnet array sensors that are collected
from all blocks of a motor.
Signal:
Each motor contains sensors that detect the magnetic field from the magnet
array. When the signal from the sensors is higher than a threshold, the signal
bit for the associated sensor is set high, otherwise it is set low.
