Read and follow all of Whelen’s written instructions when installing or using this device. Emergency vehicles are often operated under high speed stressful conditions which must be accounted for when installing all emergency warning devices. Controls should be placed within convenient reach of the operator so that they can operate the system without taking their eyes off the roadway. Emergency warning devices can require high electrical voltages and/or currents. Properly protect and use caution around live electrical connections.Grounding or shorting of electrical connections can cause high current arcing, which can cause personal injury and/or vehicle damage, including fire. Many electronic devices used in emergency vehicles can create or be affected by electromagnetic interference. Therefore, after installation of any electronic device it is necessary to test all electronic equipment simultaneously to insure that they operate free of interference from other components within the vehicle. Never power emergency warning equipment from the same circuit or share the same grounding circuit with radio communication equipment. All devices should be mounted in accordance with the manufacturer’s instructions and securely fastened to vehicle elements of sufficient strength to withstand the forces applied to the device. Driver and/or passenger air bags (SRS) will affect the way equipment should be mounted. This device should be mounted by permanent installation and within the zones specified by the vehicle manufacturer, if any. Any device mounted in the deployment area of an air bag will damage or reduce the effectiveness of the air bag and may damage or dislodge the device. Installer must be sure that this device, its mounting hardware and electrical supply wiring does not interfere with the air bag or the SRS wiring or sensors. Mounting the unit inside the vehicle by a method other than permanent installation is not recommended as unit may become dislodged during swerving; sudden braking or collision. Failure to follow instructions can result in personal injury. Whelen assumes no liability for any loss resulting from the use of this warning device. PROPER INSTALLATION COMBINED WITH OPERATOR TRAINING IN THE PROPER USE OF EMERGENCY WARNING DEVICES IS ESSENTIAL TO INSURE THE SAFETY OF EMERGENCY PERSONNEL AND THE PUBLIC.Warnings to UsersWhelen’s emergency vehicle warning devices are intended to alert other operators and pedestrians to the presence and operation of emergency vehicles and personnel. However, the use of this or any other Whelen emergency warning device does not guarantee that you will have the right-of-way or that other drivers and pedestrians will properly heed an emergency warning signal. Never assume you have the right-of-way. It is your responsibility to proceed safely before entering an intersection, driving against traffic, responding at a high rate of speed, or walking on or around traffic lanes. Emergency vehicle warning devices should be tested on a daily basis to ensure that they operate properly. When in actual use, the operator must ensure that both visual and audible warnings are not blocked by vehicle components (i.e.: open trunks or compartment doors), people, vehicles, or other obstructions. It is the user’s responsibility to understand and obey all laws regarding emergency warning devices. The user should be familiar with all applicable laws and regulations prior to the use of any emergency vehicle warning device. Whelen’s audible warning devices are designed to project sound in a forward direction away from the vehicle occupants. However, because sustained periodic exposure to loud sounds can cause hearing loss, all audible warning devices should be installed and operated in accordance with the standards established by the National Fire Protection Association.Safety FirstThis document provides all the necessary information to allow your Whelen product to be properly and safely installed.

The solder connection forms a mechanical ground that prevents mechanical stress due to lead cutting from traveling into the LED package. Use this method for the hand soldering operation,because the excess lead length also acts as small heat sink.Soldering and Handling⏹Take care during the PCB assembly and soldering process to prevent damage to the LED component. ⏹The LED component may be effectively hand soldered to the PCB. However, do this under unavoidable circumstances, such as rework. The closest manual soldering distance of the soldering heat source(soldering iron’s tip) to the body is 1.59 mm. Soldering the LED using soldering iron tip closer than 1.59 mm might damage the LED.⏹Apply ESD precautions on the soldering station and personnel to prevent ESD damage to the LEDcomponent that is ESD sensitive. Refer to Broadcom application note AN 1142 for details. The soldering iron used must have a grounded tip to ensure electrostatic charge is properly grounded.⏹Recommended soldering conditions:⏹Set and maintain wave soldering parameters according to the recommended temperature and dwell time.Perform daily checks on the soldering profile to ensure that it always conforms to the recommended soldering conditions.NOTE:1.PCBs with different size and design (componentdensity) will have a different heat mass (heat capacity). This might cause a change in temperature experienced by the board if the same wave soldering setting is used. Therefore, recalibrate the soldering profile again before loading a new type of PCB.2.Take extra precautions during wave soldering to ensurethat the maximum wave temperature does not exceed 250°C and the solder contact time does not exceed 3s. Overstressing the LED during the soldering process might cause premature failure to the LED due to delamination.⏹Loosely fit any alignment fixture that is being applied during wave soldering and do not apply weight or force on the LED. Use non-metal material because it will absorb less heat during the wave soldering process.⏹At elevated temperature, the LED is more susceptible to mechanical stress. Therefore, allow the PCB to cool down to room temperature prior to handling, which includes removal of alignment fixture or pallet.⏹If the PCB board contains both through-hole (TH) LED and other surface-mount components, solder surface-mount components on the top side of the PCB.

L12 LED保护芯片说明书

L12芯片说明书一、综述L12是一种自主设计的新型LED保护芯片，具有单颗LED损坏引起开路时能自动接通从而避免整灯不亮的功能。

在LED正常工作时，L12工作在截止状态下。

当LED损坏开路时，造成两端电压上升，当电压上升到L12的击穿触发电压时，L12自动进入导通保护模式，原来流经LED的电流将从L12通过。

在LED误反接时，电流也从L12上旁路流过，从而保护LED不被反向击穿。

Thisis automatically the case if the device does not stretch the low period of the SCL signal. If such a device does stretch the low period of the SCL signal, it must output the next data bit to the SDA line t R(MAX)+t SU:DAT = 1000 + 250 = 1250ns before the SCL line is released.Note 10:C B —total capacitance of one bus line in pF.Note 11:The parameter t OSF is the period of time the oscillator must be stopped for the OSF flag to be set over the voltage range of0.0V ≤V CC ≤V CC(MAX)and 2.3V ≤V BAT ≤3.4V.Note 12:This delay applies only if the oscillator is enabled and running.
