11.9 Lid Closure Problems
When the lid is closed, the message “Lid not closed,
please select option again” may be displayed.
A closed circuit must exist between magnets on the lid
and relays on the cover. This circuit needs to be open
when the lid is open. When the lid is pressed down, it
acts as the stop button. This requires that all magnets
are positioned correctly.
The following image shows a representation of the lid,
cover, magnet, and relays. There are two magnets on
the lid and two sets of relays on the cover.
When the lid is closed the magnet must be in a position
to correctly align with the reed relays on the cover. This
alignment allows the circuit to close and the robot to
operate.
When the lid is open, the circuit is open, preventing the
robot from operating.
When the lid is closed and pressed down, the roles of
the two relays are reversed and the circuit is open,
preventing the robot from operating.
If there are problems closing the lid, complete the Lid
Service Test.
