No. SS2-VRX100-0100 - 6 - 2. Analog output The Analog loop of this flowmeter is created by installing load resistance between the + line and - line of the analog output line. The analog output line is also used as a power-supply line for the flowmeter. 3. Pulse output/Alarm output The Pulse output/Alarm output of this flowmeter is an open collector type. Installing a current limiting resistance between a power source line and pulse/alarm output line, this flowmeter is used. Ensure to select an appropriate value of the current limiting resistance which the current does not exceed the value of the pulse output capacity. 4. To prevent noise, conduit tubes or ducts should be used for wiring. Wiring Notes 1. The cable specifications are as follows: Recommended cable: CVVS or CEVS Table 6. Flowmeter output Number of leads Cross-section area of the cable Analog output only 2-cores shield 2mm2 Analog out put+ Pulse output, or Analog output 2-cores shield x 2 2mm2 Pulse or Alarm output only 3-core shield 2mm2 2. To prevent noise, avoid locations containing noise sources, such as heavy-duty motors, transformers, and power supplies for motors, as well as locations containing high-voltage and high electric currents. 3. When using an explosion-proof model, use the Azbil corporation standard flame-proof cable gland which attached to the device.
