Wiring; Caution In Wiring; Applicable Wires; Cable Connection - Fuji Electric FSZ Instruction Manual

2.3.1. Caution in wiring

(1) We recommend using a shielded cable to extend the length of the cable for the output signal.
(2) To prevent noise intrusion, do not run the signal cable inside the same duct as that used for wires such as
power lines.
(3) If the power cable has an integrated ground wire, ground it as is.
(4) The flowmeter is not equipped with a power switch, and therefore a separate switch or breaker must be
installed for each unit.
Also, please use it while observing the following.
• Integrate the switch or breaker into the equipment.
• Position the switch or breaker appropriately, and ensure that they can be easily accessed.
• Clearly indicate that the switch or breaker is an equipment disconnecting device.
• Use a switch or breaker that conforms to local standards in the region in which they are used, or to
international standards.
(5) Connect a load resistor of 550 Ω or less to ensure a stable maximum output current of 120%.

2.3.2. Applicable wires

Use the following cables.
Dedicated cable: Power input/output signal cable based on type designation
(Type FLYF)

2.3.3. Cable connection

Indicates the cable name of the dedicated cable. Connect it to the power supply and output signal.

After turning ON the power, it takes 20 seconds to reach the measurement status.
Please warm it up for at least 30 minutes.
After warming it up, perform zero point adjustment.
