Interlock Circuit
When using an NC-12 node controller, the digital I/O on the node controller can be connected
directly to an interlock circuit as shown in
Figure 3-6 . An interlock is a user-installed circuit
that another piece of equipment in the facility activates to halt all motion on the specified
paths temporarily. When the node controller detects that the interlock circuit is activated, it
commands all paths that are associated with that interlock to suspend vehicle movement. All
motors on those paths suspend vehicle target requests and permissions and all vehicles come
to a controlled stop and are held in position by the motors. Stopping time for each vehicle is
dependent on the mass of the vehicle, including any load, and the acceleration setting of the
current movement command for the vehicle.
Multiple interlock circuits can be connected to one NC-12 node controller. Each path can then
be configured to be associated with a specific interlock bit. Any or all paths can be associated
with the same interlock bit. See the
MagneMover LITE Configurator User Manual or the
QuickStick Configurator User Manual for information on interlock configuration and use.
NOTE: An external power supply for the interlock circuit is required.
The interlock circuit, which is shown in Figure 3-6 , is connected to a digital output on the host
controller such that breaking the circuit activates the interlock. The interlock is cleared by tak-
ing the interlock signal High.

CAUTION
Automatic Movement Hazard
When the interlock is cleared movement of the vehicles on
the transport system is automatically resumed, which could
result in personal injury.
