6.2.5 Positioning of the deceleration switches
IMPORTANT!: Information on "Positioning the deceleration
switches" is available in the Planning Information publication
300-D-9010542.
6.2.6 Check/setting of the max. operating pressure (EN 81-2, art. 12.5.3)
To check the minimum static load pressure (with empty car):
1. Read the minimum static load pressure on the pressure gauge
2. Compare the minimum static load pressure on the Quality-Certifi
cate with actual minimum static system pressure on the pressure
gauge
3. If the difference is more than 5bar, but less than 10bar:
decrease or increase the maximum pressure setting valve resp. by
the amount of the difference (see below)
4. If the difference is more than 10bar:
contact the customer service
Adjusting the maximum pressure (Pressure relief adjust)
1. Slacken the locknut for screw (1)
2. Turn screw (1) approx. 2turns counterclockwise
3. Bypass the overload pressure switch (switching output s1)
4. Press emergency-lowering lever until a relevelling is triggered and
close the ball valve immediately (before the relevelling is com
pleted)
5. Slowly turn screw (1) clockwise until calculated pressure is reached
6. Tighten locknut for screw (1)
7. Open the ball valve
8. Remove the bypass from the overload pressure switch (switching
output s1)
9. Overwrite the value of the max. pepressure setting valve given on
the Quality-Certificate with the new value
