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
⇒
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
⇒
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
