2.4 Optical System

The optical system of the RF-5301PC is displayed in Figure 2-5. A 150W xenon lamp (1) is used as the light source, and in the sample compartment, trapped ozone is broken down by the internal heat of the compartment. The bright spot of the xenon lamp is enlarged via the elliptical mirror (2), and after being collimated into a beam, is focused via a concave mirror (4) on to the excitation slit assembly (3) through the entrance slit (19). Part of the beam, which is then dispersed to a spectrum via the concave diffraction grating (5), is directed out of the exit slit (20), passes through a collecting lens assembly (11), and impinges on the sample cell (12).

The concave diffraction grating used in the spectrofluorometer employs a highly efficient ion-blazed holographic grating produced by an original Shimadzu technology. For light source compensation, a portion of the excitation light is reflected by a beam splitter quartz plate (6) to a Teflon reflecting plate (7), and the scattered light reflected by the Teflon plate is passed through an aperture (21) to balance the light quantity, and is then directed to Teflon reflecting plate #2 (8). The scattered light from Teflon plate #2 is reduced by an optical attenuator (9) and directed to a monitor photomultiplier (10).

The emitted light from the cell is passed through a lens (13), and directed into the emission monochromator, consisting of the slit assembly (14) and concave diffraction grating (15). The spectral light is reflected from a convex mirror (16) and directed to the measurement photomultiplier (17).

Figure 3-9 Interface Cable Connection

3.4 Switching Power ON

Power Supply The power consumption of the RF-5301PC is about 400V. Operate the RF­5301PC from a power supply rated at least 400VA. Supply voltage fluctuations are allowable up to ± 10%. Use a voltage regulator to regulate any voltage fluctuations above ±lO%.

Grounding The power cable of the RF-5301PC consists of three wires, including the grounding conductor. Plug the power cable into a three-wire AC outlet for positive grounding. When the available outlet is of the two-wire type, ground the unit from either the grounding terminal of the power cable or that on the rear of the unit.

Plugging the Power Cable Plug the accessory power cable into the power connector on the rear of the unit, but not before checking to see that the power switch is off. Ascertain that

) the voltage setting selector is adjusted appropriately.

Xenon Power Switch The xenon power switch above the power switch is then turned ON. When all the preparations are complete, switch on the power (listen for a clicking sound). The lamp will automatically light. In addition, verify that the power display lamp on the front of the instrument is on.

RF-5301PC Hardware Manual 3-6 3-7

Page 13: manual-spectroflourometerRF5301PC

Hardware Installation

When the xenon lamp does not light, or if there is no clicking sound when the power is switched on, or when the clicking sound continues without the xenon lamp lighting, immediately switch the power OFF, and refer to

Troubleshooting, Chapter 5 in this Hardware Manual.

3.5 Software Installation

See the Software Instruction Manual, Installation, Chapter 2.

3.6 Instrument Initialization

NOTE: Before turning the power switch ON, open the sample compartment door and check to see that no packing material is left inside and that there is no object in the holder that would block light transmission.

Run the RF-5301PC software and then turn the power switch ON. Upon start­up, the unit automatically begins an initialization procedure. Each time an initialization step is successfully completed, the initialization status box displays OK, then proceeds to the next step. If an error is encountered, the unit will stop the process. In this case, see Troubleshooting, Chapter 5 in this Hardware Manual. When the initialization procedure is completed, the main screen appears.

3.7 Adjusting the Light Source Position

The Raman lines emitted from distilled water can be used to adjust the light source position. Light source position adjustment is required when the xenon lamp is installed for the first time or when it is replaced. After turning the power switch ON, wait at least thirty (30) minutes before adjusting the light source position.

Maintenance & Inspection

4. Maintenance and Inspection

4.1 Precautions in Relocating the Unit

Be sure to remove the xenon lamp from the unit before transporting the RF­5301PC. (Store the lamp in its special protective case.) Since gas is contained at high pressure inside the xenon lamp, breakage of the lamp would be very dangerous. Be very careful to avoid imparting any shock, vibration or pressure to the lamp which could cause it to break (explode).

Also, when installing a new lamp, DO NOT touch the surface of the lamp bulb. When accidental contact is made, wipe off the lamp with a piece of cloth moistened with the cleaner provided with the lamp or with ethyl alcohol. Fingerprints remaining on the lamp when the lamp is turned on could result in burnout of the lamp.

4.2 Life Time of the Xenon Lamp

The xenon lamp is a consumable part. After accumulation of excessive hours of use, the lamp will begin to flicker as the emission point fluctuates. In this condition, an unacceptable level of noise will be evident.

The recommended usage time is 500 hours. Avoid using the lamp beyond 1000 hours of service. On rare occasions, the lamp could break, causing major damage to the internal components of the instrument or injury to the operator.

4.3 Xenon Lamp Illumination Time Management

This instrument incorporates a lamp usage monitoring function. To verify the accumulated hours of illumination of a lamp, select Instrument... from the Configure menu in the menu bar. Remember to press the Reset key to reset the time indicator to 0 after replacing the lamp.

4.4 Disposing of a Consumed Xenon Lamp

Care must be taken when discarding a used xenon lamp. Inappropriate handling can be extremely dangerous, due to the possibility of the lamp exploding. When disposing of a used lamp, wrap it in thick cloth or similar material, and break it with a hammer before disposal.
