Fox K4 User Manual And Maintenance Reference

USER'S GUIDE AND MAINTENANCE REFERENCE
FOR ELECTROMECHANICAL PRESSURE AND VACUUM SWITCHES
1.

GENERAL

Pressure/vacuum switches are electro mechanical equipments which send an electric or pneumatic signal as a fixed value of pressure (or negative pressure) is reached.
Depending of the using, there are two different types:
1.1 Diaphragm pressure/vacuum switch (
very low pressures.
WARNING! • A pressure/vacuum switch isn't a safety device!
• Fixing, wiring and settings must be performed by qualified staff, and only after a careful reading of this User's Guide.

TECHNICAL DATA

2.1 This User's Guide and Maintenance Reference must be considered an integrating part of the shipment. Always check that the goods received are integral and corresponding
to the order. Compare the inscription printed on the label of the equipment, on the order and on the delivery note, issued by FOX s.r.l.; in case of discordance, don't install the
instrument on the system but contact immediately FOX Srl.
2.2 Before fixing the equipment, compare technical data shown in Tab. 1 to those printed on the label on the device.
Shaping, material and Hexagons: Ch. 24 (K4-F4-WF4), Ch. 27 (F3), Ch. 32 (K9).
