4. OPERATIONS: MANUAL CONTROL

4.1 Power up Sequence

The control electronics for the filter changer are activated by the POWER switch (MAINS)
on the back panel of the unit. Remember, when using an arc lamp with this system it is best
to turn the lamp power supply on BEFORE turning on the LAMBDA 10-B. Arc lamp power
supplies produce a high voltage lamp starting pulse that may interrupt normal operation of
microprocessor-controlled devices or damage electronics.
When power is applied, the LAMBDA 10-B performs several initial tests in order to
determine the mechanical equipment attached to the controller. As part of this process, the
filter wheel will rotate at a slow rate until sensors in the mechanical units signal that the "0"
filter position is lined up with the optical port. The wheel will then make an additional move
away from filter 0 and then back to filter 0. The controller currently automatically recognizes
three different classes of filter wheels: standard 10-position, high-speed 4-position and high-
current 10 position (32 mm). At power on, the LAMBDA 10-B rotates the filter wheel to filter
position 0. If the wheel does not rotate to this position as detected by a Hall effect sensor, the
display will indicate that there is an error. If the microprocessor detects that it is not a 10-
position wheel, the controller will only execute moves to filter positions 0 through 3.
While the unit is going through these steps, the following screen is displayed:

4.2 Main Status Screen

After the copyright screen, the unit display should be similar to one of the following,
depending on your configuration:

4.2.1 Filter Wheel/Shutter Configuration

If the LAMBDA 10-B is configured with one filter wheel and/or one shutter, the status screen
indicates the state of the filter wheel on the first line (filter size, current filter position, and
current speed), and the state of the shutter (on/off), including the mode if SmartShutter.

4.3 Dual-SmartShutter Configuration

The LAMBDA 10-B is configured for dual-SmartShutter operation when two SmartShutters
are connected to the controller with the DB25-to-two-DB9 split cable (CIQ-2). In such a
configuration, no filter wheel or other shutter may be connected, and the status screen
appears as follows.
