Interlocks
When using an NC-12 Node Controller, the Node Controller’s Digital I/O can be connected
directly to an Interlock circuit. An Interlock is a user-installed circuit that can be activated by
another piece of equipment in the facility to temporarily halt all motion on the specified Paths.
When the Node Controller detects that the Interlock circuit is activated, it commands all Paths
associated with that Interlock to suspend vehicle (puck) movement. All motors suspend vehi-
cle 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 vehicle’s load and
the acceleration setting of the vehicle’s current movement command.
Multiple Interlock circuits may be connected to a single NC-12 Node Controller. Each Path
can then be configured to be associated with a specific Interlock bit. Any or all Paths may be
associated with the same Interlock bit. Refer to the
MagneMover
®
LITE Configurator User’s
Manual
to configure the MagneMover LITE transport system to use an Interlock.
NOTE:
An external power supply for the Interlock circuit must be provided by the user.
The Interlock circuit, shown in
, is connected to a digital output on the Host Con-
troller such that breaking the circuit will activate 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 MagneMover LITE transport system is automatically
resumed, which could result in personal injury.
