6.3.3 Control top with 3 solenoid valves
Hint!
To ensure sufficient compressed air supply to the process drives, a
maximum of 2 solenoid valves are electrically controlled at the same
time! It must be ensured that no simultaneous control of the drive or
the lifting can take place at the same process valve!
Only two solenoid valves may be operated at the same time
The simultaneous operation of more than two solenoid valves will increase
the temperature to a critical and non-certified level.
► The conditions of use in chapter 2.3 must be observed.
