Light Stack Circuit
When using an NC-12 node controller, the digital I/O on the node controller can be connected
directly to a light stack as shown in
. A light stack is a user-installed visual signal
that is used to provide transport system status. The light stack can be used to monitor the sta-
tus of any, or all, paths on the node controller where it is connected. Multiple light stacks can
be connected to one NC-12 node controller. Each path can then be configured to be associated
with a specific light stack. Any or all paths can be associated with the same light stack.
The transport system supports standard three color light stacks (typically green, yellow, and
red) as shown:
•
Run Bit
(Green Light) – Vehicle movement active/enabled, expect vehicle movement.
•
Warning Bit
(Yellow Light) – System faults, the system could still be operational
with vehicles moving.
•
Stop Bit
(Red Light) – Vehicle movement halted/stopped, movement can resume at
any time with no warning.
The optional light stack circuit is the responsibility of the user and requires a user-supplied
3-color light tower and power supply (sized for the light stack) for the Digital Outputs. See
for the digital I/O equivalent circuits. See the
MagneMover LITE Con-
figurator User Manual
or the
QuickStick Configurator User Manual
for information on light
stack configuration and use.
NOTE:
An external power supply for the light stack circuit is required.
