1. Operation and interval times are PLC-controlled.
2. Use with positive-displacement distributors for metered oil delivery.
3. Includes a pressure gauge for checking operating pressure.
4. Includes an 8 kgf/cm² pressure switch for detecting oil line damage.
5. Includes a float switch for oil level detection and automatic signaling.
6. Includes a spark suppressor to reduce PLC interference from voltage surges and contact arcing and extend switch life.
7. Includes a forced-feed button. Do not hold for more than 3 minutes to avoid motor overload.
8. Includes motor thermal protection. At 100°C, operation stops temporarily for approximately 5 minutes.
9. Refer to the float / float switch specifications for contact information.
10. Refer to the diaphragm pressure switch specifications for contact information.
