CEN02 Resistance-type Electric Lubricator

Non-metered lubrication.

Timer-controlled.

Optional lubrication-on-startup mode.


Inquiry

1. Operation and interval times are timer-controlled. The control box has ACT, ALM, RUN and INT indicators and a built-in small buzzer.

2. Stores the set lubrication and interval times.

3. Two startup modes are available. The standard mode starts with lubrication: (a) lubrication first—the lubrication timer starts at power-on; (b) interval first—the interval timer starts at power-on.

4. Interval-first models retain the remaining interval after a power interruption and resume from that point at restart, avoiding repeated lubrication.

5. Includes a pressure gauge for checking operating pressure.

6. Includes a float switch for oil level detection and automatic signaling.

7. A manual lubrication button (F key) is provided. Do not hold it 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. An optional 1kgf/cm² pressure switch detects damage to the lubrication lines.

10. Refer to the float / float switch specifications for contact information.

11. Refer to the diaphragm pressure switch specifications for contact information.
