LRV-1 lift control valve
51/86
300-I-9010050-E-28/02.2012
Setting the bypass pressure with the pressure gauge, without
Handterminal
1.
Make sure that the car is empty
2.
Make sure that the pressure gauge shut-off screw/ shut-off valve is
undone (the pressure gauge indicates changing pressures in the lift
system without delay)
3.
Read the minimum static pressure on the pressure gauge
4.
Close the ball valve
5.
Press emergency-lowering lever (vents pressure in the valve)

6.
Bridge the two terminals of the relay output connected to the lift
control system (either 17a,18 or 17b,18 – depending on the
configuration of the relay output,

7.
Remove the UP solenoid plug (

)
8.
Slacken the locknut for bypass-pressure setscrew (

)
9.
Unscrew bypass-pressure setscrew (
2
) approx. 2turns
counterclockwise
10. Send UP command
11. With motor running, slowly turn bypass-pressure setscrew (
2
)
clockwise until pressure is approx. 3bar below the min. static
pressure previously read
12. Tighten the locknut for bypass-pressure setscrew (
2
)
13. Cancel the UP command
14. Remove the bridge from the terminals of the relay output
15. Refit the UP solenoid plug (
10
)
16. Open the ball valve
17. Overwrite the value of the min. static pressure given on the
nameplate (
