SUTTER INTRUMENTS LAMBDA XL LB-XL (01) PDF Document

To ensure safe operation of your SUTTER INTRUMENTS LAMBDA XL LB-XL, please adhere to the following electrical safety warnings:

Voltage: Operate the unit using 110-120 V AC, 60 Hz, or 220-240 V AC, 50 Hz line voltage. This instrument is designed for connection to a standard laboratory power outlet (Overvoltage Category II).

System Wiring: As a microprocessor-controlled device, it should be given the same system wiring precautions as any ‘computer type’ system. A surge protector and power regulator are recommended.

Grounding: Always use the grounded power supply cord set provided to connect the system to a grounded (3-prong) outlet. This protects you from injury in the event of an electrical hazard.

Servicing: Do not disassemble the system. Refer all servicing to qualified personnel only.

Moisture: To prevent fire or shock hazard, do not expose the unit to rain or moisture.

The operation of the SUTTER INTRUMENTS LAMBDA XL LB-XL involves several hazards. Please take the following precautions:

Intense Light: The unit produces high levels of visible and near-UV radiation that can cause eye damage, skin burns, or fire when concentrated. To avoid physical injury, NEVER LOOK DIRECTLY INTO THE LIGHT GUIDE OR INTO THE LAMP OUTPUT PORT, especially if the light guide is not installed. Keep skin, cloths, or anything that can be damaged by heat or intense radiation away from the end of the light guide or the lamp output port.

Explosion Risk: During operation, the bulb contents can reach high pressures, creating a risk of explosion if the quartz envelope fractures. To avoid danger, do not operate the unit with the cabinet open. Ensure fresh air can flow freely around the unit and keep the mesh screens on the vents free of dust to prevent overheating.

Lamp Operation Precautions:

• Do not disconnect the power cable when the lamp is on. Shut the lamp down first to avoid damaging the lamp module.

• Do not remove power or attempt to turn off the lamp or the unit within 1 minute of turning it on. The contents of the capsule must be allowed to fully vaporize.

• When shutting down, first stop the lamp (via keypad or software) and wait a full one (1) minute before powering off the system to allow for proper cooling.

Environment:

• The unit is designed for operation in a laboratory environment (pollution degree II).

• Operate only where there is a free flow of fresh air on all sides. NEVER aLLOW THE FREE FLOW OF AIR TO BE RESTRICTED.

SmartShutter®: The SmartShutter® is intended for controlling light in scientific applications and is not a ‘safety shutter.’ It is not designed to automatically close on power failure to prevent unintended light exposure.

To avoid damage to your optical filters and the SUTTER INTRUMENTS LAMBDA XL LB-XL system, it is essential that you use only “hard-coated” (sputter-coated) optical filters. Examples include those available from Semrock and the ET Series from Chroma Technology Corp.

If purchasing from Chroma, ensure that only ET Series sets that do not contain soft-coated filters are specified. Using soft-coated (vacuum deposit) optical filters can lead to the filters melting from the intensity of the light source, causing them to fuse to the equipment.

The SUTTER INTRUMENTS LAMBDA XL LB-XL has a universal power supply that runs on 110V or 220V AC, 50 or 60 Hz, without needing any changes to settings or fuses.

1. Make certain that the ON/OFF switch on the back panel of the cabinet is in the OFF position.

2. Plug the provided power cord into the line input socket on the power entry module on the back of the unit.

3. Plug the other end of the power cord into a power source of the appropriate voltage and frequency.

The rear panel of the unit contains the following components:

USB PORT: A USB Type B receptacle for connecting to a host computer.

POWER SWITCH: Turns the system power on and off.

LINE POWER: Socket for the power cord, which also includes the fuse module.

FUSE LABEL: Indicates the model number, supply voltage, and required fuse type.

FUSE: A compartment containing the active fuse and a spare fuse.

The light output of the SUTTER INTRUMENTS LAMBDA XL LB-XL is focused into a liquid light guide for coupling to a microscope.

1. The liquid light guide has one bare end and one end covered by a black “end sleeve”.

2. Insert the bare end of the light guide all the way into the protective heat sink provided on the unit.

3. Fasten it in place using the setscrew located in the heat sink. A 0.05 hex wrench is included for this purpose.

4. The end of the light guide covered by the sleeve is to be installed in the microscope adapter. Refer to the documentation included with your specific adapter for installation instructions.

CAUTION: The light guide has a minimum-bending radius of 40 mm (about 1.6 inches), but performance is better with more gradual bends. The light guide should be supported so there is minimal bending in the first 10 cm to get the best throughput.

NOTE: The retaining ring that sets the distance between the heat sink and the light source is factory-installed. It is strongly advised that this ring not be adjusted.

To load filters, you must first access the filter wheel assembly inside the SUTTER INTRUMENTS LAMBDA XL LB-XL.

Accessing the Filter Wheel:

1. Remove the upper portion of the left side panel (the filter access panel).

2. Locate and remove the two wheel lock screws and the retaining bracket.

3. Pull the filter wheel assembly out. Do not disconnect the 25- or 15-pin ribbon cable.

Filter Specifications:

The filter wheel accepts 1-inch or 25mm diameter filters. The maximum allowable thickness depends on whether a spacer is used:

Loading Filters into Filter Cups:

1. To align the desired filter position with the loading port, it is easiest to use the controller. If the filter wheel was not pre-installed, connect it to the unit with the 25-pin ribbon cable and turn the power on (the lamp does not need to be on).

2. When the unit powers on, it will “HOME” itself, aligning the “0” filter position with the optical port. Filter position #5 will be at the loading port. The filter position at the loading port is always five positions ahead of the one shown on the display (e.g., if display shows ‘F2’, then position ‘F7’ is at the loading port).

3. Once the desired cup is positioned, it is advisable to turn off the unit.

4. Unscrew the access plug from the loading port on the motor side of the filter wheel using a large coin.

5. Using the provided spanner wrench, engage the two notches on the threaded retaining ring inside the cup and turn it counter-clockwise to remove it.

6. Remove the spacer ring and blanking disc (if present).

7. Place the desired filter into the cup, ensuring correct orientation relative to the light source as per the filter manufacturer’s instructions.

8. Re-install the spacer ring, if the filter thickness allows.

9. Re-install the threaded retaining ring. DO NOT OVER TIGHTEN; it only needs to be firmly seated.

10. After loading all filters, check that no retaining rings are projecting above the filter cup edge, then replace the loading port plug.

The SUTTER INTRUMENTS LAMBDA XL LB-XL supports three modes of operation for the SmartShutter, providing flexibility for different experimental needs.

1. Fast Mode:

In this mode, the shutter’s motion is optimized for the fastest possible open and close times. Both opening and closing will take about 8 msec from the time the command/trigger is received. The controller will not accept new commands for about 12 msec after a command is received to allow for system overhead.

2. Soft Mode:

This mode offers less vibration at the expense of slower open and close times. In SOFT mode, the typical time to open or close is 60 msec.

3. Neutral Density Mode:

In this mode, the user can select the extent to which the shutter opens, allowing for light attenuation without changing its wavelength or spatial distribution. The opening can be selected in steps from 1 (no opening) to 144 (complete opening). The time to open and close depends on the number of steps selected. A complete opening of 144 steps takes about 38 msec.

The SUTTER INTRUMENTS LAMBDA XL LB-XL can be fully operated manually from the keypad on the top panel.

Initial State: Upon power-up, the unit defaults to USB (ON LINE) mode. To use the keypad, press the LOCAL key.

Key Functions:

• LOCAL: Sets the controller to manual/local mode. Pressing it toggles between the lamp control menu (top two display lines) and the filter wheel/shutter menu (bottom two display lines). An ‘@’ symbol indicates the active menu.

• ON LINE: Sets the controller to remote/computer control mode.

• Numerical keys 0 to 9: Used to select menu functions, filter positions, and speed.

• F1: Accesses the main menu for the active function (lamp or wheel/shutter).

• F2: Used as the “Enter” key for the wheel and shutter menu.

• SPEED: Accesses the wheel speed selection mode.

• SHUTR: Manually opens or closes the shutter.

Operating the Lamp:

1. Press LOCAL until the ‘@’ is on the top line to activate the lamp menu.

2. The display will scroll through the options: 1 – START LAMP, 2 – STOP LAMP, 3 – SET BRIGHTNESS, etc.

3. Press 1 to start the lamp. It takes about 12 seconds to reach full intensity.

4. Press 2 to stop the lamp. You will be asked to confirm (1 for Yes, 0 for No). NOTE: Do not turn off the lamp within 1 minute of starting it.

5. To adjust intensity for all filters, press 3 (SET BRIGHTNESS), enter a value from 25-100, and press F2.

6. To set different intensities for different filters, press 4 (EDIT BRIGHTNESS) and follow the on-screen prompts.

Operating the Filter Wheel and Shutter:

1. Press LOCAL until the ‘@’ is on the third line to activate the wheel/shutter menu.

2. To change filter position, key in the desired filter number (0-9) and press F2.

3. To change speed, press the SPEED key, enter a new speed (0-7, where 0 is fastest), and press F2.

4. To open/close the shutter, press the SHUTR key. The status (ON/OFF) is shown on the display.

The switching time (in milliseconds) for the SUTTER INTRUMENTS LAMBDA XL LB-XL depends on the selected speed setting (0-7) and the number of filter positions moved. Speed 0 is the fastest. Note that a 5-filter position move is the longest possible, as the controller always rotates in the shortest direction. The highest speed that can be used will depend on the weight of the filters mounted in the wheel.

* NOTE: Speed 0 should be used only with 4-position filter wheels (LB10-WHS4 or LB10-WHS4IQ).

Advanced controller functions are accessible by pressing the F1 key from the wheel/shutter menu (when the ‘@’ symbol is on line 3 of the display).

1. TTL Function (F1 -> 1):

This menu allows you to enable or disable TTL triggering for the shutter via the TTL input on the rear of the cabinet.

2. TEST Function (F1 -> 2):

This menu provides several testing routines:

• LOOP: Performs a loop test for the internal serial port connection to the lamp (for production testing only).

• SPEED: Tests the different possible speeds of the wheel with the current filter load and suggests the optimal (PREFERRED) speed.

• SHUTTER: Runs a demonstration program for the SmartShutter.

• DEMO: Runs a demonstration program for the SmartShutter/filter wheel combination.

3. MODE Function (F1 -> 3):

This allows you to choose one of three shutter modes (FAST, SLOW, NEUTRAL DENSITY). You can assign the selected mode to all filters, the current filter, or a new specified filter. For Neutral Density, you will be prompted to enter the number of steps (1-144).

4. CONFIG (Configuration) Function (F1 -> 4):

This menu allows you to modify the factory default configuration (Filter 0, Speed 1, Fast shutter mode, closed shutter).

• DEFAULT: Allows you to set a new default configuration (speed, filter, shutter mode) or reset the current configuration to the existing default.

• SHUTTER MODE: Allows you to save the current shutter mode as one of three configurations (M1, M2, M3) or restore a previously saved configuration.

To ensure compatibility with various remote control software packages, you may need to configure the Product Identification and the Baud Rate on your SUTTER INTRUMENTS LAMBDA XL LB-XL.

Setting the Product Identification (Product ID):

Some software may not recognize the default “LBXL” product ID. You can change it to “10-B” for compatibility with software designed for the Lambda 10-B controller.

1. Press LOCAL to enter manual mode.

2. Press LOCAL again if needed to activate the wheel/shutter menu (bottom two lines).

3. Press F1, then 4 (CONFIG).

4. From the remote-control config menu, press 1 (DEVICE TYPE).

5. The current ID is marked with a star (*). Press 1 to select “10-B” or 2 to select “LBXL”. The display will briefly confirm your selection and return to the main screen.

Setting the Baud Rate (for Virtual Com-Port Driver):

If using a Virtual Com Port (VCP) driver to emulate a serial port over USB, you must match the baud rate between the software and the instrument. The default is 128000.

1. Follow steps 1-3 above to get to the remote-control config menu.

2. Press 2 (BAUD RATE).

3. The current rate is marked with a star (*). Select the desired rate: 1 (9600), 2 (19200), 3 (115200), or 4 (128000). It is generally safest to select 9600, as this is a common default for serial ports.

4. The display will briefly confirm your selection and return to the main screen.

Follow these steps to install the necessary drivers for your SUTTER INTRUMENTS LAMBDA XL LB-XL.

1. Ensure the SUTTER INTRUMENTS LAMBDA XL LB-XL is plugged into a power source and its power switch is set to OFF.

2. Connect the square-shaped “device” end of the USB cable to the USB receptacle on the back of the Lambda XL.

3. Turn the power switch on the back of the Lambda XL to ON.

4. Make sure your computer is powered up and the Windows operating system has fully loaded.

5. Plug the other rectangular “host” end of the USB cable into an unused USB port on your computer or a connected USB hub.

7. If this is the first time installing the drivers, you may see a “Digital Signature Not Found” dialog box. This is normal; press the “Yes” button to continue.

8. Windows will then display a “Files Needed” dialog box, asking for the location of the driver files.

9. Click the “Browse” button and navigate to the folder containing the downloaded driver files for the Lambda XL.

10. Once the correct folder is selected, click OK. Windows will copy the necessary files and complete the installation.

Routine maintenance is important for the proper function and longevity of your SUTTER INTRUMENTS LAMBDA XL LB-XL.

Cleaning:

Routine cleaning is required to prevent excessive dust accumulation. Wipe all exterior surfaces with a dry, soft, cotton cloth.

Cooling and Ventilation:

For proper cooling of the lamp module and electronics, you must keep the mesh screens covering the intake vents free of dust. Place the unit away from any objects that could block the flow of cool air to the vents or deflect hot air back towards the vents.

Filter Wheel and SmartShutter® Maintenance:

Occasionally inspect all retaining rings to be certain that they are seated correctly into the filter holders and cups.

CAUTION: The filter wheel and SmartShutter are precision-machined parts mounted on a stepper motor shaft. They DO NOT REQUIRE LUBRICATION. Attempting to lubricate any part of these assemblies will void the warranty and may damage the motor.

Changing the Light Bulb:

The light bulb in the Lambda XL is not field or customer serviceable. If the bulb requires replacement, the entire system must be returned to Sutter Instrument Company for replacement and recalibration.

If the controller fails to power up when the power switch is turned on, the line power fuse may have blown. A spare fuse is located within the fuse holder.

1. Unplug the power cord from the power entry module on the back of the controller.

2. This will reveal a small slot just under the edge of the fuse holder.

3. Use a screwdriver to carefully pry the holder straight out of the power entry module.

4. The fuse that is readily visible is the “active” fuse. The spare fuse is concealed in a separate compartment within the holder.

5. To remove the spare fuse, press down on one end of the compartment to push it out of the other end. You can use the old fuse as a tool for this.

6. Replace the active fuse with the spare.

7. Re-install the fuse holder and power cord.

If the controller still fails to power up with the new fuse installed, contact Sutter Instrument technical support.

Replacement Fuse Specification:

Replace only with the same type and rating: 5 Amp, 250V, 5 x 20mm, Time Delay fuse (EIC 60127-2, Sheet III). (Examples: Bussmann S506-5-R (RoHS), or Littelfuse 218.005.P (RoHS)).

Movement errors can occur due to several factors related to speed, weight, and timing.

Filter Wheel Movement Errors:

• Cause – Filter Weight vs. Speed: The system is optimized for fast exchange of 2 filters. Adding more or heavier filters increases the inertial load. If the weight is excessive for the chosen speed, it can lead to movement errors. The controller has an error detection and recovery routine that will home the wheel (position 0) if an error is detected.

• Cause – Oscillation: If the filter weight is slightly excessive for the speed, the wheel may oscillate when stopping instead of stopping quickly. This can also happen during a move if the speed excites a resonance frequency.

• Solution: Select a slower speed setting. This uses a different acceleration/deceleration profile and will generally eliminate errors caused by weight or oscillation.

SmartShutter Movement Errors:

• Cause – Successive Moves: Failures can be produced by combining multiple actions with very short time intervals (less than 50 msec) between them. A small oscillation at the end of one move can carry over and interfere with the beginning of the next move.

• Solution: If you experience errors with short delays between moves, experiment with small changes to the delay to find the most secure interval. If a short delay is critical, try using a slower shutter mode (e.g., Soft Mode).

General Troubleshooting Tips for Movement Errors:

• Always test using the same filter wheel load weight and timing intervals that will be used in your actual experiment.

• If frequent movement errors occur, the solution usually requires a compromise between fast switching speed and the convenience of keeping many filters loaded.

• To minimize vibration transfer to your microscope, place the Lambda XL on a solid surface that is separate from the surface the microscope is on (e.g., do not place it on the same air table).
