Interlock Safety System
Safety Guard Interlock Function:
The Safety Guard is an aluminum fence around the perimeter of the carriage. Motion
Motors disabled when it is not properly seated include the Gantry Drive and Carriage
Drive. Also UV Lamps switch Off (Not UV Cooling Fans), and Z-Axis drive
initializes (Carriage drives to Top Position and Holds there).
Carriage Interlock must be cycled to ensure the Interlock is functional and that the
Carriage Safety Guard is in place. User interface message with user intervention
acknowledgment is required to re-enable functioning.
Power-up Interlock Test for Carriage
On power-up, the Interlock System will not permit the motion motors to be turned,
so the machine will be unable to initiate motion. To satisfy the requirements for
Machinery Directive, the Carriage Interlock must be cycled to ensure the Interlock
is functional and that the Carriage Safety Guard is in place. Upon cycling of Carriage
Interlock, no motion may be initiated without acknowledgment of the Operator, i.e.
User interface message with operator intervention acknowledgment.
Beacon Light Status
The green beacon light is mounted to the top surface of the printer carriage. The
purpose of this light is to indicate basic printer status to the operator.
Beacon off: indicates the printer can be approached without caution. The machine
cannot initiate movement since the interlock Safety System has disabled all motion
to the electrical control system.
Beacon on: indicates the Machine is powered up and ready to initiate motion. This
tells an operator to approach the machine with caution, because it could initiate
motion at any moment.
