Setting the bypass pressure with a pressure gauge
(car out of sight)
1. Set the "SIU Type" parameter in the C−DELCON to "Off"
I make a note of the existing setting
I ⇒ Page 71, Section 5.1.4.2
2. Read the minimum static pressure on the pressure gauge
3. Close the ball valve
4. Press emergency−lowering lever (vents pressure in the valve)
I ⇒ Page 36, Section 3.1
5. Remove the UP solenoid plug (10)
6. Slacken the locknut for bypass−pressure setscrew (2)
7. Unscrew bypass−pressure setscrew (2) approx. 2 turns
counterclockwise
8. Send UP command
9. With motor running, slowly turn bypass−pressure setscrew (2)
clockwise until pressure is approx. 3bar below the min. static
pressure previously read
10. Tighten the locknut for bypass−pressure setscrew (2)
11. Cancel the UP command
12. Refit the UP solenoid plug (10)
13. Open the ball valve.
14. Reset the "SIU Type" parameter in the C−DELCON to the setting
noted down in Step 1.
The bypass pressure is now set
