C−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 ⇒ Page 71, Section 5.1.4.2
2. Set the "Demand val. red." parameter in the C−DELCON to "Off"
I make a note of the existing setting
I ⇒ Page 71, Section 5.1.4.2
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
