TDFS型号温度散热流量切换器技术参数手册说明书
The SERIES TDFS on change of flow.to cool. The flow Higher FlowEnsure that the process fluid is compatible with the wetted materials, and do not exceed the maximum device ratings.Ensure that the system is not pressurized before installing or removing this device or other objects from the system. The deviceand/or object may become a projectile.Do not use with abrasive fluid mixtures (The polysulfone may be abraded.)Use caution if fluid temperature changes or fluid composition changes are present in the end application. Verify that the deviceoperates properly if either is present. The setpoint will shift if the specific heat, density or viscosity of the fluid changes.Mount the TDFS so that the sensor extends into the flow by 10-25% of the pipe ID. Use PTFE tape on the process connection to reduce the risk of leaks. For proper flow measurement, the sensor must be fully submerged in the fluid. Bubbles, turbulence, and sediments will cause improper operation. For best operation, mount 30° to 150° off vertical on horizontal runs (See Figure 2). Allow a straight run of at least 12 pipe di-ameters upstream and 5 pipe diameters downstream to ensure optimal flow measure-ment. For optimal repeatability, ensure the flow switch is not operating in the transition region (laminar to turbulent flow).ELECTRICAL CONNECTIONThe power input and switched outputs are individually fused at 0.5A and are reverse polarity protected. A shielded 4 conductor cable provides the electrical connection to the TDFS. The cable drain wire must be connected to earth ground in CE applications or when strong RF fields are present.Two open collector switched outputs are provided. One is normally open (NO), and the other output is normally closed (NC). The output logic is shown in Table 1.SETPOINT ADJUSTMENTThe setpoint may be adjusted with the supplied magnet. There are two setpoint targets on the unit located under the LED status indicator on opposite sides of the unit (see Figure 4). Either setpoint target may be used, and either end of the magnet may be used. If the setpoint does not set easily, try reversing the magnet.Steps:1) Ensure that the unit is properly installed and powered.2) Set the system flow to the desired setpoint flow rate.3) Tap the setpoint target three times with the supplied magnet. Move the magnet approximately 2 inches away from the target between each tap. The taps should be approximately 1 second apart. The LED status indicator will blink slowly when the setpoint request is recognized. The slow blink will stop when the setpoint has been stored.©Copyright 2017 Dwyer Instruments, Inc.Printed in U.S.A. 5/17FR# 443813-00 Rev. 4STATUS INDICATORThe status indicator (See Figure 4) provides visual indication of the TDFS status. Two status indicators are located on opposite sides of the unit. Each status indicator has one red LED and one green LED. Table 2 describes the status indicator states.If an error condition is present, the unit will continue measurement attempts until the problem has cleared. The status indicator will cycle on and off during this time.AGENCY APPROVALS AND TEST STANDARDS CE: CENELEC EN 55011: 2006 CENELEC EN 61326-1: 2006 IEC 61000-4-2: 2008 IEC 61000-4-3: 2006 IEC 61000-4-4: 2004 IEC 61000-4-5: 2005 IEC 61000-4-6: 2006 CENELEC EN 55022: 2006 FCC PART 15 CFR TITLE 47: 2008 ICES-003: 2004 Digital Apparatus (Industry Canada) ANSI C63.4-2003 2004/108/EC EMC DIRECTIVEMAINTENANCE/REPAIRUpon final installation of the Series TDFS, no routine maintenance is required.
