Flow Transmitter Wiring; Cautions In Wiring; Applicable Wires; Treatment Of Wiring Port - Fuji Electric Time Delta-C FSV-2 Instruction Manual

3.3.1. Cautions in wiring

(1) Use a special coaxial cable (FLYC) as a signal cable between the detector and flow transmitter (FSV). Do
not provide a junction or splice of the signal cable midway.
(2) The signal cable between the detector or flow transmitter should be run in metallic conduits. Upstream and
downstream signal cables may be put in the same conduit but, to avoid interference, do not put the power
cable together.
(3) For output signal, use a shielded cable, where possible.
(4) To avoid noise interference, do not put the cables together with heavy duty line or the like into the same
duct.
(5) If a ground wire is included in the power cable, connect it to ground as it is.
(6) A power switch is not provided on the instrument and must be mounted separately.
(7) Seal unused wiring ports by furnished caps.

3.3.2. Applicable wires

Use the following cables.
 Power cable
 Output signal cable
 Detector-flow transmitter cable : Signal cable by type designation

3.3.3. Treatment of wiring port

The casing of the flow transmitter is IP66 and IP67. However, if installed in a humid place, the wiring ports must be made
airtight to avoid ingress of moisture, condensation, etc. Be sure to use the waterproof glands furnished with the instrument
in order to ensure the waterproof means. A gland, which is not ready to be used, should be sealed by supplied cover.
Do not install the instrument where there is a risk of flooding.
