Disassembly
WARNING!
Risk of injury from compressed air/pressure surge.
Products under pressure can cause personal injury.
•
Before carrying out any work on the product, switch off the compressed air
supply and secure it against being switched back on.
1. Switch off pressure to the pneumatic system.
2. Switch off analogue setpoint signal.
3. Switch off supply voltage and lock switch to prevent reactivation.
4. Allow the device to cool down.
5. Disconnect VPPL electrical connections.
6. Decommission the PREL.
7. Disconnect VPPL mechanical mounting.
