Obrázek 1: Ranco O16-108 Pressure Control Switch. The image displays the main control unit with a visible pressure scale (showing values like 10, 15, 20, 30, 40, 50 in PSI and bar), the Ranco logo, and a capillary tube extending from the bottom, coiled, and terminating in a brass fitting. The scale indicates "CLOSES ON PRESSURE RISE" and "SWITCH LOW EVENT".

4. Nastavení a instalace

Proper installation is crucial for the optimal performance and longevity of the Ranco O16-108. Consult a qualified technician for installation if you are not experienced with electrical and pressure systems.

4.1 Montáž

• Mount the control unit in a location free from excessive vibration, moisture, and extreme temperatures.
• Ensure adequate clearance for wiring and adjustments.
• Use appropriate fasteners to secure the unit firmly to a stable surface.

4.2 Tlaková přípojka

• Connect the capillary tube's brass fitting to the pressure source.
• Ensure a leak-free connection. Do not bend the capillary tube sharply, as this can damage the sensing element.
• The capillary tube transmits pressure changes to the control unit.

4.3 Elektrické zapojení

• Refer to the wiring diagram provided with the product (not included in this manual) for specific connections.
• Connect power supply and load wires to the appropriate terminals. The contact type is Normally Open (NO) and the terminal is SPDT (Single Pole Double Throw).
• Ujistěte se, že všechny spoje jsou bezpečné a izolované.

5. Návod k obsluze

The Ranco O16-108 operates automatically based on the set pressure points. Adjustments are made via the visible scale on the front of the unit.

5.1 Setting Pressure Points

• Identify the desired cut-in and cut-out pressure values for your application.
• Use a small screwdriver or adjustment tool (if required) to move the indicators on the pressure scale to the desired settings. The scale shows values in both bar and PSI.
• The device is designed to close on pressure rise, meaning the switch will activate when the pressure reaches the set point.
• The "SWITCH LOW EVENT" and "MINUS DIFF" markings on the scale relate to setting the differential pressure.

5.2 Manual Operation / Reset (if applicable)

While the primary operation is automatic, some Ranco pressure controls may feature a manual reset or test button. If present, this button allows for manual activation or resetting of the switch. Consult the specific product labeling for details on any manual functions.
