Tracking a component placement position when production is resumed
When the system finishes re-clamping a board after start of production, the following screen
appears.
When you press the “Trace” button in the Operation area, the system tracks a component
placement position to allow you to check to see if a component is placed on the next component
position.
(1) The last suspended position
The component placement position from which the system resumes production is shown here.
Menu item Description
Circuit No. Displays the circuit number from which the system resumes production.

Description
Placed
The system assumes that a component is already placed at the placement
position from which it resumes production.
It starts placing a component from the position next to that from which it
resumes production.
Check to see if a component is placed at production start position (specified in
the “Restart position” field on the “Prod Cond” screen) with tracking a
component placement position.
Not placed
The system assumes that any component is not placed at the placement
position from which the system resumes production.
The system starts placing a component from a placement position where it
resumes production.
When you press the <START> switch, the system starts placing a component on a board.
When you press the <STOP> switch, the system returns to Idle mode.

Returning a nozzle
If the system cannot attach a nozzle on a head correctly when nozzles are replaced during PWB
production, the production is terminated abnormally.
At this time, the system displays the “Nozzle Error” screen, and provides you with the function form
returning the nozzle held with the head manually or automatically.
Displaying the “Nozzle Error” screen
(1) Return nozzle mode
Select how to return a nozzle that failed to be attached on the head.
Menu item Description

The system displays the “Question” message for asking you whether a feeder or any other device is
located under the head or not in order to move down the Z-axis after the head and the nozzle move
to the nozzle detachment position.
After the Z-axis moves down, the message for asking you to remove the nozzle appears on the
screen.
If there are two or more nozzles that cause a nozzle attachment error, the system repeats
performing this process.
Press the <OK> button, and then perform the same process for other head(s) that cause(s) a nozzle
attachment error. When the system finishes returning nozzles of all heads, the Z-axis moves up,
and then moves to the waiting position.
Automatically returning a nozzle
When you select the <Auto> button, and then press the <START> switch, the system automatically
returns a nozzle that causes a nozzle return error.
After the system returns nozzles of all heads, it moves up the Z-axis and then to the waiting position.
Operation after a nozzle is returned
If you return a nozzle after production is terminated abnormally, the system is put into the
Production Idle state.
If the system detects a nozzle attachment error at start of production, it starts production after
returning the nozzle.
