Introduction
The 3B supports both geometric center (the block is place on the geometric center of the lens
shape) and optical center blocking (the block is placed on the layout reference point of the lens). In
addition, the 3B can rely on a host computer to calculate decentration or it can do the calculations
internally based on information entered by the user or downloaded from a host. The combination
of these two elements results in four choices for the Default Lens Blocking field on the 3B Setup
Screen: Geometric Center – Calc, Geometric Center, Optical Center – Calc, and Optical Center.
The “- Calc” indicates that the decentration calculations are done by the 3B. On the Job Screen,
the Blocking softkey will cycle through these four choices. It must be noted that there may be
different fields required when switching between blocking methods.
In general, the default lens blocking choice is driven by the lab itself and the equipment used to
edge the lens after it is blocked. If lens information is entered at a computer that calculates a job
ticket, the 3B should generally rely on the information provided by the host computer (Geometric
Center). If the 3B is getting shape information directly from a tracer, no blocking information is
available and so it will have to be entered at the 3B in order to calculate decentration (Geometric
Center – Calc or Optical Center – Calc).
Rev. 1.9

Geometric Center – Calc
The figure below shows the Job Screen for geometrically centering the block on the shape using
the decentration calculated by the 3B. This option should be used when interfaced to a 4T tracer or
other host that provides shape data, but not blocking information.
Notice that the layout reference point (in this case, the center lensometer dot) will be placed or
decentered 2.5 millimeters in towards the nasal side of the lens (in this example) from the block.
The relationship between the block and the shape will never change regardless of the decentration.
Changes in decentration only affect the relationship between the block and the layout reference
point.

Geometric Center
The figure below shows the Job Screen for geometrically centering the block on the shape using
the decentration provided by a host. This option should be used when interfaced to a host computer
that provides shape data and decentration information. This option may also be used if the operator
prefers to calculate the decentration manually and enter it directly on the screen instead of entering
the data fields required for the 3B to calculate decentration. It can also be used to slightly adjust
the blocking location calculated by the “Geometric Center – Calc” for lens cutout.
Notice that the layout reference point (in this case, the center lensometer dot) will be placed or
decentered 2.5 millimeters in towards the nasal side of the lens (in this example) from the block.
The relationship between the block and the shape will never change regardless of the decentration.
Changes in decentration only affect the relationship between the block and the layout reference
point.
This blocking option also allows the use of Arrow Mode, that is, using the arrow keys to
graphically change decentration. Press the MODE button to toggle between Arrow Mode and
standard mode. The Arrow Mode icon will appear at the far right end of the title bar. The user can
then use the arrow keys to change the decentration. Press the MODE button again to leave Arrow
Mode and resume normal use of the arrow keys.

Optical Center – Calc
The figure below shows the Job Screen for optically centering the block on the shape using the
decentration calculated by the 3B. Optical center blocking is generally used when it is desirable for
the edger to do the decentration. The Optical Center – Calc mode allows the operator to view the
lens shape for cut out.
Notice that the layout reference point (in this case, the center lensometer dot) will be placed
directly over the block. The relationship between the block and the layout reference point will
never change regardless of the decentration. Changes in decentration only affect the relationship
between the block and the shape. Alternatively, for progressive lenses, the fitting cross may be
placed 5 millimeters above the block. For segmented lenses, the segment may be placed
5millimeters down and 5 millimeters in from the block. These alternatives are specified in the Seg.
Blocking and Prog. Blocking fields on the Setup Screen.

Optical Center
The figure below shows the Job Screen for optically centering the block with the least amount of
information. This option is a good choice for simply placing the block on the layout reference
point of a lens. No shape data or blocking information is required or used for this option.
Notice that the layout reference point (in this case, the center lensometer dot) will be placed
directly over the block. Alternatively, for progressive lenses, the fitting cross may be placed 5
millimeters above the block. For segmented lenses, the segment may be placed 5millimeters down

Updating Program Code
Users of the 3B may upgrade their unit’s program code in three ways:
• Replace the memory chip in the 3B with a new memory chip containing the new code
•
Load the new code using a PC running MS Windows
•
Load the new code from a diskette using a 6E or 7E Edger
Replacing the Program Code Chip
When you need to replace the program code memory chip, follow
the directions given below:
Rev. 1.9
1.
Turn the 3B power off and unplug the power supply.
Disconnect any serial cables and the foot switch, if applicable.
2.
Prior to removing the panel in Step 3, visually note how the
panels mate with the display, the right side panel, the base
housing, and the panel behind the lens platform.
3.
Using a 5/64-inch hex wrench, remove the two screws
securing the upper-right panel to the metal chassis at the back
of the 3B—see picture.
4.
Remove the top screw securing the upper-left panel as well—
see picture.
5.
Gently disengage and remove the panel by pulling it upwards
and towards the back of the 3B. This will expose the 3B’s
circuit board.
5-1

6.
Locate the memory chip—see picture. It has a
white label with the version of the software that
is being replaced.
7.
Grasp the chip at its ends using your thumb and
index finger. Slowly and gently “rock” the chip
out of the socket. This does not require much
force, but should be done slowly to avoid
bending any of the chip’s legs.
8.
Note that the one end of the replacement chip is
marked with a semi-circular indentation. Orient
the replacement chip so that these markings are
towards the base of the 3B (that is, downward). Carefully align the legs of the replacement
chip with the socket and gently press the chip into the socket with a slight rocking motion.
Inspect the chip for mal-alignment or bent legs.
9.
Plug the power supply into the 3B and turn the unit on. Inspect the screen to verify that the
desired software version number is displayed. If the unit does not power up properly, turn it
off, unplug the power supply, and gently remove the chip to inspect for bent legs. Carefully
straighten any bent legs and re-install (Step 7).
10. Once the chip is successfully installed, turn off the 3B power and unplug the power supply.
Re-install the upper-left housing panel. A small flat-bladed screwdriver may be helpful in
“tucking in” the edges of the panel where they meet with other panels.
11. Secure the panel with the two screws removed in Step 3; then reinstall the screw removed in
Step 4.
12. Plug in the power supply, any serial cables and the footswitch, if applicable. Store the memory
chip that you removed in the packing materials that the replacement chip was shipped in. If for
any reason your 3B needs to be reverted to the prior firmware version, this chip can be reinserted using these instructions.
