Important: the car must be empty
Setting the bypass pressure with the Handterminal
(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. Remove the UP solenoid plug (10)
3. Slacken the locknut for bypass−pressure setscrew (2)
4. Unscrew bypass−pressure setscrew (2) approx. 2 turns
counterclockwise
5. Connect the Handterminal to the C−DELCON and press key 3 on
Handterminal => null point or feedback value will be displayed
6. Send UP command
7. With motor running, slowly turn bypass−pressure setscrew (2)
clockwise until feedback value rises (visible on the Handterminal
display)
8. Turn bypass−pressure setscrew (2) back by half a turn
counterclockwise
9. Tighten the locknut for bypass−pressure setscrew (2)
10. Cancel the UP command
11. Refit the UP solenoid plug (10)
12. Reset the "SIU Type" parameter in the C−DELCON to the setting
noted down in Step 1.
The bypass pressure is now set
