Issue 2Edwards Signaling Catalog uConventional InitiatingMEARate Compensation Heat Detectors302 SeriesBox mount Surface MountOverviewSeries 302 heat detectors are designed for use in normal environ-ments as well as environments where the detectors are subject to weather, moisture (internal condensation), and explosive atmo-spheres. They are normally-open devices designed to close an electrical circuit upon activation. All models feature rate compen-sation and are available with either 135 °F (57.2 °C) or 194 °F (90 °C) ratings. They are self restoring, hermetically sealed, shock and corrosion resistant, and are tamperproof.Standard Features• Rate compensation offsets thermal lag • Self-restoring – no manual reset required• Explosion proof and weatherproof models available • Weatherproof models available that do not require a special backbox • Box mount and surface mount models availableApplicationSensors rated at 135 °F (57.2 °C) will not respond to momentary temperature fluctuations less than 30 °F/minute between 60 °F (16 °C) and 100 °F (38 °C). Sensors rated at 194°F (90 °C) will not respond to momentary temperature fluctuations less than 50 °F/minute between 60 °F (16 °C) and 150 °F (66 °C). 302 Series sen-sors should not be used in environments where conditions exceed these parameters. Do not install them in hot air ducts, in front of heaters, in paint booths that use heat to cure paint, or any otherlocation subject to temperature fluctuation.194 °F (90 °C)-40 °F (-40 °C)150 °F (66 °C)The sensor's aluminum tube acts as a heat collector when sourc-es of heat radiate directly on the tube. Install these sensors out of direct sunlight and away from radiating heat sources including the direct flow from heaters and heat ducts.Page 2 of 4 D A T A S H E E TS85001-0589Not to be used for installation purposes. Issue 2Typical WiringElectrical Rating6-25 VDC 1 amp 125 VDC0.5 ampMaintenance302 Series heat sensors are low maintenance. Sensors automati-cally restore when temperatures drop below their rated tempera-tures. The accumulation of dust and dirt does not normally affect the sensors’ operation.TestingTesting for operation is simple and can be done before or after the sensor has been installed. Heat the sensor with a hair dryer (do not use any device with an open flame to test sensors). The sen-sor should operate shortly after the hot air is applied.Refer to NFPA 72, National Fire Alarm Code and/or the localauthority having jurisdiction to determine testing frequency, record keeping, and other testing considerations.Rate Compensation302 Series sensors feature rate compensation, which improves performance by offsetting thermal lag, an inherent property of conventional fixed temperature heat sensors.A slow rate of temperature rise allows the heat to penetrate the inner expansion struts. The tubular shell and the struts expand slowly until the total device has been heated to its rated tempera-ture level of 135 °F (57.2 °C) or 194 °F (90 °C). At this point, the silver contact points close and an alarm is initiated.When subjected to a rapid rate temperature rise, there is not as much time for heat to penetrate the inner strut. However, the rapid lengthening of the shell allows the struts to come together at a lower level.When the surrounding air temperature returns to below the rated level, the shell contracts, forcing the contacts to open, thus auto-matically resetting the sensor.Fine silver contact Expansion strutsHigh expansion sensingshell, 0.040 anodized aluminum Heat control sleeve Setting screwDevcon hermetic sealWARNING – Use For Property Protection Only: Heat detectors do not protect life against fire and smoke. In most fires, hazardous levels of smoke, heat and toxic gases can build up before a heat sensor would initiate an alarm. Independent studies indicate that heat sensors should only be used when property protection alone is involved. In cases where life safety is a factor, the use of smoke detectors is recommended.Under no circumstances should heat detectors be relied upon as the sole measure to ensure fire safety. However, if they are spaced in accordance with the specifications found under Application, these sensors can contribute, within an overall fire safety program, to reducing the risk of avoid-able property losses.When used with automatic fire suppression systems such as pre-action and deluge sprinkler systems, carbon dioxide systems, halon systems, and dry chemical systems, at least two sen-sors should be used to initiate the alarm. This is commonly referred to as cross-zoning or prioritymatrix zoning and is necessary to eliminate premature discharge of the system.

2. 主 控 制 驱 动 电 路 为 HD44780 HITACHI 及 其 他 公 司 全 兼 容 电 路 如 NT3881 NOVATEK KS0066 SAMSUNG SPLC78A01 SUNPLUS
一 处理保护膜 在装好的模块成品表面贴有一层保护膜 以防在装配时沾污显示表 面 在整机装配结束前不得揭去 以免弄脏或损坏显示面

五 焊接 在焊接模块外引线 接口电路时 应按如下规程进行操作 1. 烙铁头温度小于280°C 2. 焊接时间小于3∼4s 3. 焊接材料 共晶型 低熔点 4. 不要使用酸性助焊剂 5. 重复焊接不要超过3次 且每次重复需间隔5分钟
六 模块的使用与保养 1. 模块的外引线决不允许接错 在您想调试液晶模块时 请注意正确接线 尤其是正 负电源的接线不能有错 否则可能造成过流 过压 烧毁电路上的芯片等对液晶模块 元器件有损的现象 2. 模块在使用时 接入电源及断开电源 必须在正电源稳定接入以后 才能输入信号电 平 如在电源稳定前或断开后输入信号电平 有可能损坏模块中的IC及电路 3. 模块使用时 接入逻辑电源和驱动电源的顺序应是先逻辑电源 后驱动电源 断电 时 应先驱动电源 后逻辑电源 这样做有助于保持屏的良好显示效果和避免在上 电 断电时的电压冲击损坏 所以推荐使用带控制的DC-DC电源做为模块的驱动电源 4. 点阵液晶模块显示时的对比度 视角与温度 驱动电压关系很大 所以 如果VEE调整 过高 不仅会影响显示 还会缩短模块的使用寿命 5. 因为液晶材料的物理特性 液晶的对比度会随着温度的变化而相应变化 所以 您加 的负电压值应该随温度作相应的调整 大致是温度变化10 电压变化1伏 为满足这 一要求 您可做一个温度补偿电路 或者安排一个电位器 随温度调整负电压值 6. 不应在规定工作温度范围以外使用 并且不应在超过存储极限温度的范围外存储 如 果温度低于结晶温度 液晶就会结晶 如果温度过高 液晶将变成各向同性的液体 破坏分子取向 使器件报废 7. 用力按压显示部分 会产生异常显示 这时切断电源 稍待片刻 重新上电 即恢复 正常 8. 液晶显示器件或模块表面结雾时 不要通电工作 因为这将引起电极化学反应 产生 断线 9. 长期用于阳光及强光下时 被遮部分会产生残留影像
