Testing the pipe−rupture valve (for C−DELCON software version
2.110 or higher)
1.
On the Handterminal, select the Pipe rupture" function in the In-
formation (4) menu under Commands"
I
⇒
2.
Press and hold the + key on the Handterminal; the "DOWN" LED on
the C−DELCON will start to flash
3.
Send DOWN command
4.
Wait until the car is accelerating
5.
When the triggering speed is reached, the pipe rupture valve closes
and travel stops.
Important
: Releasing the + key on the Handterminal stops the travel,
and the maximum feedback value is displayed. If the DOWN command
is still present on quitting the menu, travel will resume normally.
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 man-
ual 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
6.
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
