How to Use this Manual

This manual is organized in a manner that is best suited for the typical manner in which the

reader would learn about the system, and then install, operate, and maintain it. Prior to the

table of contents of this manual is a disclaimer and a series of cautionary and warning notes

that should be read first. This first chapter provides an overall description of the system,

leaving more in-depth technical information towards the end of the chapter. The next

chapter describes how to install the system, followed by one or more chapters that provide

operation instructions, and ending with a chapter on maintenance. Following the final

chapter are several appendices that provide supplemental information. The installation

chapter covers everything related to installation, from unpacking the equipment as received,

through to ensuring that everything is correctly installed and is operating correctly. The

operation chapters cover the two basic types of user interaction with the system: Manual

(local) control and external computer control. Please take the time to read these instructions

to assure the safe and proper use of this instrument.

2 supersedes the previous Lambda 10 filter wheel controller

providing enhanced capability while retaining the same outstanding mechanical

performance. The Lambda 10-2 controller can control up to two filter wheels and two high-

speed shutters, and provides for both manual (local) control as well as external computer

control (via either of the provided serial (RS-232) or parallel interfaces).

The controller system is designed around three embedded microcontrollers: one slave for

each wheel and a master for control and communication. The electronics for two wheels and

two shutters are already installed, even if you only ordered a single wheel system. If you add

a second wheel or shutter later, there will be no additional electronics to buy. The embedded

microcontrollers automatically determine the number of filter wheels that are installed, so

there are no jumpers or switches to set.

LAMBDA 10-2 OPERATION MANUAL – REV. 2.04 (20120224)

The controller can run a single wheel and shutter under remote control through a parallel

input using the same simple protocol as the original Lambda 10 controller. New commands

have been added so that the 8-bit parallel input can efficiently control two wheels and two

shutters without using any additional lines. The serial input uses the same command set as

the parallel port, and provides full control of two wheels and two shutters. Either use the

B-25 cable provided to connect to the parallel port or the B-9 cable provided to connect to

the serial port.

The following instructions are meant to help you set up the Lambda 10-2 and become

familiar with the manual mode of filter selection. Further details on controller functionality,

filter installation, and remote communications can be found in other sections of this manual.

two filter wheels, each one with or without a shutter. If the Lambda 10-2 system is

purchased with only one 10-position 25mm (1-inch) filter wheel, you may wish to add a

second filter wheel of the same type later, in which case the second filter wheel can be added

without modification. A 10-position 32mm and a 5-position 50mm filter wheel are also

available for use with the Lambda 10-2 controller. Each port of the controller to which a

32mm or 50mm filter wheel is to be connected, however, must be modified by Sutter

1.3.1 Stepping Motor Operation

Stepping Motor OperationStepping Motor Operation

Stepping Motor Operation

Stepping motors are not as familiar to most people as the common C motor, but there are

some similarities. The C motor consists of an armature, an electromagnet mounted on a

rotating shaft, which is located inside a permanent magnet. Current is supplied to the

electromagnet through brushes that rub on contacts on the armature. When the

electromagnet is energized, the armature rotates to align the poles of the electromagnet with

the opposite poles of the permanent magnet. Of course, before this can occur, the rotation of

the armature changes the contact plates rubbing on the brushes so that the current is

reversed. This causes the poles of the electromagnet to reverse, establishing a force for

continued rotation. This switching action is called commutation.

In stepping motors, the rotating element, called a rotor, is generally a permanent magnet

while the fixed element, the stator, is the electromagnet. The key difference between

stepping motors and C motors, however, is the method of commutation. The C motor

commutates automatically as it rotates. Thus, the timing of the commutation is determined

by the speed of rotation, which may vary with the load or applied power. The commutation of

the stepping motor is set by external electronics, forcing the motor to rotate at a

predetermined rate. If the load is such that the motor does not have the force to produce the

correct rate of rotation, the rotation will become erratic and may even reverse.

The force exerted between two magnet poles is proportional to the square of the distance

between the poles. A motor with a single electromagnet and only two poles would exhibit

considerable loss of power when the distance between the poles of the permanent magnet

and the electromagnet was greatest. It is understandable that, in most practical C motors,

the armature has more than two poles. This allows the commutation to occur over a smaller

angle of rotation, so that the active poles can always be relatively close to the poles of the

permanent magnet.

LAMBDA 10-2 OPERATION MANUAL – REV. 2.04 (20120224)

Stepping motors are also made with multiple poles on both the rotor and stator the exact

arrangement determines the number of steps per revolution. The motor used in the Lambda

10-2 has 200 steps per revolution (1.8 degrees per step). There are usually two windings in

the stator, and a single step of rotation is produced by reversing the current on one of the

windings. Reversing the current on the second winding will then produce another step. If the

first winding is then reversed again, returning to its original value, a third step will result.

Finally, reversing the second winding, so that both windings are back to their original state,

will produce a fourth step. This pattern may then be repeated to continue rotation in the

same direction. Reversing the sequence produces steps of rotation in the opposite direction.

The rate and distance of rotation is determined by the rate and number of commutation

steps. As long as the current is held constant in both windings, the rotor will not rotate. This

makes the stepping motor ideal for producing fast start and stop movements. Some

limitations should be considered. Given that there are only 4 states of the control electronics

(2 polarities for each of the 2 windings) but 200 steps per revolution, it follows that, for each

of these four states, there are 50 possible rotary positions. In order to establish the absolute

position an external sensor must be added. Absolute position only needs to be determined

once so long as the subsequent moves occur without errors.

Correct operation of stepping motors, which is outlined above, is not always obtained. If the

motor lacks the torque to accelerate and decelerate the load at the rate indicated by the

control electronics, the resulting move may differ from that commanded by the control

electronics. For instance, if enough external force is applied, the motor shaft may be rotated

even though the command signal has not changed. For small rotations (less than 3.6

degrees), the motor shaft will return to the correct position if the force is removed. For

larger rotations, the shaft will stop at the nearest of the 50 correct positions for that

command signal when the external force is removed.

2.2.1 Vibrations

VibrationsVibrations

Vibrations

The Lambda 10-2 filter wheel system was designed to produce fast filter changes with a

minimum of vibration. The microprocessor controls the trajectory of each move using

microsteps with programmed acceleration and deceleration profiles. The result is a system so

smooth that customers using the Lambda 10 for the first time have called to report that

their wheel isn’t turning simply because they could not hear or feel anything.

LAMBDA 10-2 OPERATION MANUAL – REV. 2.04 (20120224)

Although the Lambda 10-2

is smooth and quiet, even the slightest vibration can produce

problems for the electrophysiologist. Vibration can come from several sources. The most

pronounced effects normally come from the high-speed shutter, if that option has been

included. The shutter produces a very sharp impulse which is best avoided by finding

another way of turning the light on and off such as turning to a blanked filter position.

When the motor accelerates and decelerates the filter wheel rapidly, the torque applied tends

to turn the motor and the Lambda housing in the opposite direction. If the housing is not

firmly attached, this may appear as vibration that increases with the selected speed and the

weight of filters loaded. This is not usually a problem if the wheel is firmly mounted to a

good solid surface.

Stepping motor-based systems can produce considerable vibration and noise if the rate at

which steps are taken excites a system resonance. This problem is greatly reduced by

reducing the step size with microstepping, as in the Lambda 10-2. Even when microstepping

is used, it is possible to produce vibration by selecting a speed that is not optimal or by

starting a new move within a few milliseconds of the end of the previous move. For example,

with only two typical filters loaded speed 1 should give a very smooth move that stops with

little vibration. Speed 2, 3, and 7 may all produce more vibration at the end of a move with

this load even though they are slower speeds.

At a minimum, we recommend that the Lambda 10-2 should be firmly mounted to a solid

surface by the support stand, which is included with each unit. o not depend on the optical

coupling between the microscope and the Lambda 10 to support and stabilize the Lambda

10. This configuration will be adequate in many cases. If there is still too much vibration, the

wheel may be mounted using the support stand, but with an air gap between the Lambda 10

and the microscope.

The best cure for vibration is isolation. One simple approach is to mount the filter wheel to a

wall or a separate table. If the microscope is on an air table, be aware that the microscope

might drift relative to a filter wheel mounted on a separate, stable surface. In such cases, it

may be better to couple the Lambda 10 to the microscope with a flexible light guide. Contact

Sutter Instrument for detail of our light-guide adapter system.

FIRST TIME USE chapter of this manual for instructions. Now move the mounted filter

wheel to the approximate final location and adjust the filter wheel to the desired height. The

filter wheel can be mounted on the posts in either orientation (optical port up or down), as

required. The filter wheel can now be interfaced with other instruments (e.g. a microscope

and a light source) using an appropriate adapter (Figure 2-4). If you need to purchase an

adapter or require a custom adapter for your experimental setup, please contact the

Technical Support staff at Sutter Instrument Company by phone (415 883-0128) or by E-

Once the filter wheel has been attached to the other instrument(s), tighten the wing screws

to lock the filter wheel at its final height. It is intended that the filter wheel be supported on

the two posts included with your system. These posts can be screwed into the base provided

or into any surface with ¼”-20 holes drilled on 6” centers at an appropriate position on the

LAMBDA 10-2 OPERATION MANUAL – REV. 2.04 (20120224)

tabletop or optical bench. When using the support rod base always secure it to the tabletop

using the toe clamps provided with the system.

If a heavy light source is to be used (such as a vapor lamp with integral igniter) it should

have its own separate support system.

If your filter wheel has a shutter, the side of the filter wheel on which the shutter is installed

(the “motor side” as shown in Figure 2-4) would typically be mounted toward the light

source. Placing the shutter between the lamp and filters limits the amount of heat and light

to which the filters are exposed and increases the filters’ useful lifetime.

threaded end of these rods to facilitate tightening with a wrench. The pair of support

base clamps should be used to anchor the base to some convenient location for testing.

These clamps are designed to allow anchoring to any of the popular hole-patterns found

in optical benches.

2. Slide the filter wheel down onto the support rods and lock it at a convenient height using

the wing screws on the mounting ears of the filter wheel.
