CEWB Pressure-relief Electric Lubricator (External Twin Knobs)
Metered oil delivery. Timer-controlled. Selectable lubrication startup mode.
1. Operation and interval times are set using knobs outside the control box. ACT and INT indicators are provided.
2. Use with positive-displacement distributors for metered oil delivery.
3. Two startup modes are available; interval first is standard. (a) Lubrication first: operation timing begins at power-on. (b) Interval first: interval timing begins at power-on.
4. Includes motor thermal protection. At 100°C, operation stops temporarily for approximately 5 minutes.
5. Interval-first models include memory. If power is interrupted during an interval, operation resumes with the remaining interval after restart, avoiding repeated lubrication.
6. Includes a float switch for oil level detection and automatic signaling.
7. Includes a buzzer that sounds when the oil level is low.
8. Includes a forced-feed button (F button). Do not hold for more than 3 minutes to avoid motor overload.
9. Includes a pressure gauge for checking operating pressure.
10. Refer to the float / float switch specifications for contact information.
