CAUTION
Risk of Property Damage
Do not apply power to the system before checking all wiring connections. Improper wiring of this
terminal may cause a short circuit across the 24 VAC power supply on FX-PCV models. A short circuit
may result in a tripped circuit breaker or blown fuse. If using a transformer with a built-in fuse, the
transformer may need to be replaced.
CAUTION
Risque de dommages matériels
Ne mettez pas l’appareil sous tension avant d’avoir vérifié toutes les connexions du câblage. Le câblage
inadéquat de cette borne peut causer un court-circuit sur l’alimentation électrique de 24 V c.a. des FX-
PCV16xx-1 modèles. Un court-circuit peut causer le déclenchement du disjoncteur ou le grillage d’un
fusible. Si vous utilisez un transformateur avec un fusible intégré, vous pourriez devoir remplacer le
transformateur.
To wire the FX-PCV1615/1626/1628/1630 controller:
1. Terminate wiring according the appropriate figure in
.
2. Wire network sensors and other devices to the FX-PCV's SA Bus.
3. Ensure that the FX-PCV’s device address DIP switches are set to the appropriate device address.
(See
.) Also, activate the EOL switch if necessary.
4. Connect the FX-PCV controller to 24 VAC, Class 2 power.
Note:
If you are using the FX-PCV1615/1626/1628/1630 controller with the Wireless Field
Bus System, refer to the
WNC1800/FX-ZFR182x Pro Series Wireless Field Bus System Bulletin
(LIT-12012378
) or the
FX-ZFR1800 Series Wireless Field Bus System Bulletin (LIT-12011660
).
FX-PCV terminal functions, ratings, requirements, and wiring
guidelines
Input and Output wiring guidelines
Table 3 provides information about the functions, ratings, and requirements for the FX-PCV input
and output terminals, and Table 4 provides guidelines for wire sizes and cable lengths.
In addition to the wiring guidelines in Table 3, observe these guidelines when wiring FX-PCV inputs
and outputs:
• Run all low-voltage wiring and cables separate from high-voltage wiring.
• All input and output cables, regardless of wire size or number of wires, should consist of twisted,
insulated, and stranded copper wires.
• Shielded cable is not required for input or output cables but is recommended for input and
output cables that are exposed to high electromagnetic or radio frequency noise.
• Cable runs of less than 30 m (100 ft) typically do not require an offset in the input/output
software setup.
