4.3.1 Checking the test numbers
S The valve test number is stamped on the body (below the manual
emergency−lowering valve) ⇒ 1.2.2.
S The C−DELCON test number is on a label on the connector ⇒ 1.4.
Important: always quote the test number when making enquiries. This
makes it easier for the factory to help you!
Important: the test numbers on the C−DELCON and the valve must be
the same to avoid the need for resetting.
4.3.2 Checking the minimum static pressure
To check the minimum static pressure (with empty car):
1. Open pressure gauge shut−off valve
2. Read the minimum static pressure on the pressure gauge
3. Compare minimum static pressure on rating plate with actual
minimum static system pressure on the pressure gauge
I ⇒ Page 9, Section 1.2.1, Item (4)
4. If the difference is more than 5bar, the maximum pressure setting
must be increased by the amount of the difference (⇒ 4.3.4)
I Bypass pressure too high: car travels past landing
I Bypass pressure too low: UP starting jolt
The minimum static pressure shown is correct
Important: if the difference is more than > 10bar, please contact
Customer Services.
