TATTLETALE 信号器和磁性开关
Tattletale 报警器和磁性开关是将 Swichgage 接触操作转化为决策和操作警报或关闭设备的神经中枢。这些开关是用于报警或停机装置的电气负载承载装置。Tattletale 报警器指示哪个监控功能失败导致警报或关闭磁性开关没有。磁性开关基本上用作闭锁继电器。我们的 tattletale 报警器会指示机械发动机的受监控功能何时发生故障，并告诉您发生故障并导致警报或停机的具体功能。我们的信号器可以在保护您的发动机方面发挥巨大作用，以提醒您发动机出现问题，以确保您的设备和操作员的安全。我们的 tattletale 报警器还用于机械、柴油或火花点火发动机，用于脱水、灌溉、污水提升站、发电石油和天然气应用。我们的信号器可用于任何需要更高电流触点才能打开导致停机的发动机或应用。”
开关报警器和磁开关是将Swichgage 触点操作转化为决策和操作报警或关机设备的神经中枢。这些开关是报警或停机装置的电气负载装置。报警信号器指示哪些监控功能失效导致报警或关闭磁开关不起作用。磁开关基本上起到闭锁继电器的作用。
Tattletale annunciators and magnetic switches are the nerve centers that translate Swichgage contact operations into decisions and operate the alarm or shutdown device.These switches are the electrical load carrying devices for the alarm or shutdown device. Tattletale annunciators indicate which monitored function failed leading to the alarm or shutdown magnetic switches do not. Magnetic switches operate basically as a latching relay.

产品应用
磁开关和开关式信号机可用于发动机或电动机。各种电路、延时和触点配置可用于匹配电源和操作模式，仅用于报警、关机前报警或关机。对于分电器点火发动机，磁性开关打开分电器线圈电路，导致停机。对于磁电机或CD点火，磁开关使点火输出接地。一些型号的柴油机也可以关闭燃油阀，而不是接地，或者除了接地之外。柴油机可以通过关闭燃油或空气供应来关闭。磁开关和开关信号器可以接通或断开这些发动机的电路。对于电动机应用，各种磁开关可用于操作电动机起动器、直接固定线圈或与适当的墨菲变压器继电器组件一起使用。Magnetic switches and Tattletale annunciators are available for use with engines or electric motors.Various circuits, time delays and contact configurations
are available to match the power source and mode of operation required for alarm only, alarm before shutdown or shutdown only.For distributor ignition engines, the magnetic switch opens the distributor coil circuit to cause shutdown. For magneto or CD ignitions the magnetic switch grounds the ignition output. Some models can also trip fuel valves instead of or in addition to grounding the gnition.Diesel engines are shut down by either closing off the
fuel or air supply. Magnetic switches and Tattletale annunciators can make or break circuits for these engines.For electric motor application, various magnetic switches are available to operate the motor starter, holding coil directly or in conjunction with appropriate Murphy Transformer-Relay assembly.

NOTES:
The information above indicates features/configurations available for each model.
1. Coil Voltage - Coils are specific voltage rated or multiple voltage rated.
2. Contacts - This is the control circuit output. In the lathed position the NCH contact has a "hot" output. In the latched position, the NCG has a "grounded" output; in the tripped position, the NOG has a "grounded" output.
3. Latch Type - Refers to whether the magnetic coil is momentraily energized to trip or requires continuous power in the operating mode and de-energizes to trip.
4. Reset Type - Refers to manual or electric reset; manual indicating type is a TATTLETALE.
5. Time Delay - Indicates operation of the time delay. |
