JLN-740 高精度速度和距离日志说明书
JLN-740High accuracy speed and distance log Doppler logwww.jrc.amThe units feature a color LCD touch display for the main and sub displays, allowing you to view important information and adjust brightness on all displays from a single location.• Advanced interfacing• Various accessories available • Various remote displaysFeaturesThe JLN-740 series is a single axis water SDME compliant with the IMO MSC.96 (72) standard, required on all internationally voyaging ships exceeding 300 GT. Boasting never-before-seen accuracy for speed measurement, the JLN-740 is also installed with our company’s proprietary bubble detection function, which informs you when measurement accuracy is impaired due to air bubble contact.Precise ship speed trackingThe JLN-740 series utilizes digital signal processing, which, coupled with optimizations to existing speed measurement waveforms and the reliability of ship bottom mounting, has resulted in water speed measurement with accuracy up to 0.03kn or 0.3% in all models (measured at fixed speeds)That accuracy of information allows for highly fuel-efficient speeds, which means faster voyages with less waste. Along with improved speed measurements, the series also has greatly improved ship speed tracking, relaying all the information you need for precise navigation during berthing.T ouch operationWith just one physical power button, the 5-inch color main display and 6.5 and 8.4-inch for the remote displays are operated by touch operation. The touch screens can be easily read during daylight but also in darkness, with excellent clarity, even when viewed from a wide angle. All displays feature dimmable backlighting and have a graphical user interface is logical, easy to use and consistent throughout. All displays are designed for the industrial environment found onboard of ships, ensuring years of problem free operation.Cost-effective operationThe doppler speed log is also available with a cost-effective 4.5-inch display with the main data displayed in large characters of easy reading. In addition that the display is fully dimmable and has backlit keys, it features dual LED backlight (white and orange) making it easy to operate in various light settings on the bridge.Remote supportThe JLN-740 supports the JRC original Remote Maintenance System (RMS), one of the core elements of JRC’s customer operations support philosophy. With the VDR connected through LAN, the JLN-740 doppler log can be monitored from shore using JRC’s FB or GX satellite communications system. This allows a cost-effective determination of the operating status, software version installed but also firmwarecan also be updated through J-Marine Cloud.Bubble detectionA long-unsolvable problem with doppler-based waterspeed measuring systems was reduced accuracyfrom bubbles making contact with the measuringdevice on the bottom of the vessel. The JLN-740series detects when bubbles contact the transducer,and using proprietary technology from JRC alertsyou of reduced measuring accuracy via the display.Confirming the source of the issue typically requiresvisually examining the device on the bottom of theship. However, onboard air bubble detection allowsyou to skip unnecessary preventive maintenance.Distribution processorThis speed log incorporates a highly reliable interfacing field. You can easilyconnect a wide range of additional equipment to optimize your configuration. Asecond display, smaller remote displays and analog indicators are just a few ofthe possibilities. The JLN-740 can also output the measurement information toradar and ecdis.Signal processorThe transducer room has a quite bad environment with regard to vibrationand humidity, therefore, before signal is distributed to various equipment, thetransducer is directly connected to the processor, minimizing loss of signaland extending cable length to hundreds of meters.Snap on mountingOur standard main touch screen display and two remote displays feature our famous and unique snap on flush mount system, making it possible to fit the display without tools. The display can easily be pushed into the frame and kept in position by a click/spring system. As a result, a minimal amount of screws or mounting bolts are visible and allows for easy maintenance.IMO compliantThe JLN-740 series is designed according to the latest IMO regulations on all internationally-voyaging vessels exceeding 300 GT and meets the standards for the IEC environmental test standards. When used with JRC’s satellite log JLN-720, ships exceeding 50,000 GT will meet the requirements for IMO MSC.334(90). JRC is continuously developing and evaluating new products, based on future IMO requirements that will contribute to your future safety and navigation at sea.1. If used in combination with JLN-7202.

T7755ETS控制说明书
小汽机ETS柜说明（T7755）
1．控制柜尺寸：800×600×2200（长×宽×高）
2．控制柜颜色：
3．控制柜配置：一台ETS控制柜控制2台小汽机,且两台小机的保护系统各自完全独立设置。
本柜需输入两路220V AC，5A容量的独立电源，经切换后供机柜和PLC电源。
每小汽机由两台PLC（Modicon M340系列）控制两停机电磁阀，即一台小
机由两套保护系统控制，便于机组安全运行和ETS的维护工作。
4．I/O信号：
4．1．停机等输入信号和PLC通道对应表(单台小机)：
复位信号接点动合复位。
4．2．输出信号和PLC通道对应表(单台小机)：
5．使用：当任一停机条件满足时，ETS发出停机指令时，其停机输出具有保持功能，且输出相应一路停机原因指示。
若停机后要再投入，需进行复位操作，可按一下柜内复位按钮AN1或远程复位来实现停机输出和停机指示输出的同时复位。
K1，K2为总旁路和排汽压力旁路开关，在调试和启动过程中，可根据需要，把开关打倒旁路位（闭合位）。
当总旁路K1打倒旁路时，所有停机输入都将旁路，包括超速停机。
K3为超速旁路开关，当把开关打倒旁路位（闭合位）时，则超速保护功能功能旁路。
运行时，必须把K1，K2，K3旁路开关打到投入位（开路位）。
ETS柜出厂时，停机电磁阀停机逻辑设为带电停机，若要改为失电停机，则只需将PX-A1-19 和PX-A1-22端子上的线头拆掉改接至PX-A1-25端子上即可。

q New Optional Preamplifier for
Signal Amplification
Model 7405 Near Field Probe Set with New Optional Preamplifier ETS-EMCO’s Model 7405 Probe Set is a
passive, near field probe set designed as
a diagnostic aid for locating and
characterizing sources of E and H-Field emissions. The set consists of three loop probes, one stub and one ball probe, an
extension handle, an optional battery-
powered preamplifier, and a foam-lined
carrying case with a manual and application note.The handle of each probe terminates in a BNC connector. Probes are designed to be used with a signal analyzing device such as an oscilloscope or spectrum
analyzer. The optional preamplifier is useful when signal amplification is necessary for the analyzing device.The loop probes are H-Field selective and directional. Sensitivity is relative to loop
diameter. For example, the 6 cm loop can be used to make a general survey for H-Field emissions, while the smaller diameter loops can isolate specific sources.The ball and stub probes are E-Field selective and omni-directional. The stub probe is designed for precise E-Field source location, such as signal traces or IC pins. The ball probe has a large sensing element and is capable of locating weaker signals.
Typical applications include locating and characterizing emissions from PCB’s,IC’s, etch runs, cables, cover seams, etc.Standard Configuration q

of 100 kHz to 3 GHz. The preamplifier enhances the sensitivity of spectrum analyzers, oscilloscopes and other receivers. The unit can be ordered with either Type BNC connectors or type N
connectors. A wall-mounted power supply
is included (please specify 110 or 220 V AC).Purchase as an option to the Model 7405probe set or as a stand-alone product.

Omni-directional Ball Probe identifies E-Field signals over
a broad frequency range.
Stub Probe provides E-Field measurement near the signal source.
Note: Power input to probe should be limited to a maximum
of 0.1 watt to safeguard sensitive circuitry.
Loop Probes offer varying sensitivities to H-Field emissions.
