5.7.4.10 Shutters (Option)
With the shutter option, the length of the PCB is entered on the Control Menu (Figure 5-27). This data,
along with the conveyor speed, is used to determine the opening time of the outlet (exit) shutter. The
"Shutters" button on the "My Oven" screen opens a screen that allows you to enable and disable the
shutters.
Figure 5-27 PCB Length
To setup the shutter system:
1. Enter the PCB length in the Control Menu (Figure 5-27).
NOTE If the PCB length is not entered correctly, an error will occur.
If the entered length is too small, the PCB will be detected at the exit before its
estimated time of arrival. For safety reasons, the shutter will open but an error
message will appear.
If the entered length is too great, the shutter will open before the PCB arrives.
This will create an error because no board will be detected at the exit.
2. Adjust the SMEMA settings:
My Oven > SMEMA (Figure 5-28).
a. PCB sensor delay on = 1 sec
Adjust this setting to match the unloading time of the upstream equipment.
b. PCB sensor delay off = 1 sec
This setting influences the time the inlet shutter closes after it has passed the inlet
sensor.
c. Inlet and outlet delays = 30 sec
This relates to board jam errors or load and unload problems with adjacent
equipment and prevents error messages.

Operation 5-27
Additionally, there is a delay function implemented to cope with product carriers and other product
related processes. Select
My Oven > Shutters and enter the delay time in the "Shutter Out Delay Open"
textbox. This allows the user set an earlier opening time than the time calculated by the software.

NOTE The shutters function on SMEMA signals and inlet and outlet sensors open and close
when SMEMA detects a board. In case of a standalone UV-9, the user needs to
implement a switch or foot pedal to simulate a SMEMA signal.
5-28 Operation
Manual Mode
Press the
MANU button to open the Manual Mode screen. This is generally used by maintenance
personnel to close the entrance and exit shutters on demand (Figure 5-31).
