LRV lift control valve
Installation and commissioning
300−I−9010212−E−10/08.08
Testing the pipe−rupture valve (up to C−DELCON software version
2.100 or with WinDelta32 PC program)
1.
Set the "SIU Type" parameter in the C−DELCON to "Off"
I
make a note of the existing setting
I
⇒
2.
Set the "Demand val. red." parameter in the C−DELCON to "Off"
I
make a note of the existing setting
I
⇒
3.
Send a "Down" command to the controller
4.
Wait until the car is accelerating
5.
Remove the feedback plug (
25
) from the Hall sensor
6.
When the triggering speed is reached, the pipe rupture valve closes
and travel stops.
Important
: after the pipe rupture valve has closed, pressure can again
build up between the C−LRV and the pipe−rupture valve, causing the
pipe−rupture valve to re−open. If the pipe rupture valve is to remain
closed for a long period, this pressure must be vented through the
manual emergency−lowering valve on the C−LRV.
If the hose/pipe is actually burst, the pipe−rupture valve will always
remain closed.
Very slight leakage through the pipe−rupture valve is permissible.
The pipe−rupture valve has been successfully tested
7.
Cancel the DOWN command
8.
Refit the feedback plug (
25
) to the Hall sensor
9.
Reset the "SIU Type" parameter in the C−DELCON to the setting
noted down in Step1.
10. Reset the "Demand val. red" parameter in the C−DELCON to the
setting noted down in Step 2.
11. In order that the pipe rupture valve re−opens and the elevator is
ready for service: build up pressure using the hand pump or carry
out an upwards travel.
The system is once again ready for use
