Description:
This document describes micro-switches designed for controlling feeder blocks in a dual line lubrication system. Various series of feeders are mentioned, each with adjustable discharge capacities, suitable for ensuring the correct delivery of lubricant to critical friction points. The installation of micro-switches on both sides of the feeder is necessary for proper piston movement control.

Specifications:
- Electrical feeding: up to 10A 250V AC or 5A
- Protection degree: IP 55
- Working temperature: -15°C to +80°C
- Working pressure: 200 bar max.

Installation and Operation:
Micro-switches are installed on the turret side and the opposite side of the feeder. Installation involves removing the turret cover and adjusting screws, then securing the micro-switch. Electrical connections should follow the diagram on the micro-switch cover. The function involves lubricant entering specific holes to move pistons and activate contacts, signaling piston strokes.

Maintenance:
The components are not subject to heavy thermal or mechanical stress. For spare parts, order micro-switch G with part no. 38031.
