Working Principle Energizing the coil produces a magnetic force that shifts the pilot spool, which controls pilot air pressure at both ends of the main spool; pressure difference moves the main spool, switching compressed air from P to A or B to drive cylinder extend or retract. De-energizing releases the spring, returning the main spool and reversing the cylinder. The manual override directly shifts the spool for commissioning without power.
Installation Requirements
- Manifold or tubed mount with sealing gasket
- Filter-regulate-lubricate compressed air
- Air pressure 1.5 to 10 bar
- Verify coil voltage before wiring
- Tighten DIN plug
- Temperature -5 °C to +60 °C
- Evenly tighten manifold mounting bolts
Precautions
- Compressed air must be filtered to 40 µm
- Medium must contain no corrosive gas
- Coil voltage must not exceed rating
- Periodically inspect seal wear
- Do not force manual override
- Store spares in dry environment
