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
PCV 16xx-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 PCV1617 or PCV1632 controller:
1. Terminate wiring according to the appropriate figure in
2. Wire network sensors and other devices to the PCV's SA Bus.
3. Wire the FC Bus in a daisy chain.
4. Ensure that the PCV’s device address DIP switches are set to the appropriate device address.
. Also, activate the end-of-line (EOL) switch if necessary.
5. Connect the PCV controller to 24 VAC, Class 2 power.
PCV terminal functions, ratings, requirements, and wiring
guidelines
Input and Output wiring guidelines
Table 2 provides information about the functions, ratings, and requirements for the PCV input and
output terminals, and Table 3 provides guidelines for wire sizes and cable lengths.
In addition to the wiring guidelines in Table 2, observe these guidelines when wiring 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 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. Cable runs over 30 m (100 ft) may require an offset in the input/output software
setup.
Maximum cable length versus load current
Use Figure 8 to estimate the maximum cable length relative to the wire size and the load current (in
mA) when wiring inputs and outputs.
FC and SA bus and supply power wiring guidelines
Table 5 provides information about terminal block functions, ratings, and requirements.
Table 5 also provides wire size, cable type, and cable length guidelines for wiring the PCV
communication buses and supply power.
