Example of application :
1) Unlocking a door if the pressure on a pneumatic circuit drops below 2 bars
- Level of Performance required = "PL c" in accordance with ISO 13849-1
- Gas temperature = 20°C
- Type of gas = air with lubricant
- Pressure controller reference = PS-Nb-NH-P2 (2B) -CAT1
- Interlock reference = VIGILGUARD-SFR
2) Vacuum control trays with film
- Level of Performance required = "PL c" in accordance with ISO 13849-1
- Gas temperature = 100°C
- Type of gas = air + steam + vegetable oil
- Pressure controller reference = VS-Nh-S-V900 (-0.9B) - CAT1
3) Stop the machine if the pressure drops below 2 bars
- Level of Performance required = "PL e" in accordance with ISO 13849-1
- Gas temperature = -30°C
- Type of gas = air
- Pressure controller reference = PPS-Nh-NT-P2 (2B) - CAT1
- Extension to PL e = AWAX 26XXL
