4.4 Setting cut-out points
!
The cut-out points of the VLE 2130 EL are pre-set
at the factory and do not usually need to be altered
on initial commissioning. They should however be
checked.
!
The voltages of the potentiometers must be measu-
red if the lower and upper cut-out points are chan-
ged. Changes are only permissible in the 200 mV and
4,8 V voltage range.
i
We recommend only altering these factory settings if
absolutely necessary or if expressly requested by the
customer.
i
The stored values are retained even with the power
supply switched off.
The following settings are to be checked:
R
The specified lower and upper support arm cut-out
points.
R
Equalization of the difference in height of the two
lifting carriages.
R
The position of the automatic safety stop on lowe-
ring.
Standard settings:
Cut-out point Remarks
Lower cut-out point The clearance between the lowest
point of the support arm and the floor
should be 10 mm.
Upper cut-out point The distance between the top edge
of the column base plate and the lo-
west point of the standard loadbe-
aring component must not exceed
1900 mm.
Safety stop At least 200 mm between the lowest
point of the support arm and the floor.
!
When setting the lifting carriages for the first time
or following repair work, these must be set at least
15 mm higher than specified for normal operation in
the lower position on account of the run-on.

0 Operation basic setting
1 Storage of lower cut-out points
2 Equalization of support arm height differences
(not used)
3 Storage of upper cut-out points
4 Main column support arm single traverse
5 Secondary column support arm single traverse
6 Storage of safety stop position and additional acoustic
signal on further lowering of support arms
7* Potentiometer test
8* Activation / diagnosis function
9 PC mode in conjunction with PC diagnostic software
* If a fault occurs during the test, this is encoded and stored in
the EEPROM. The control system can then no longer be set to
operating mode. If operating mode is selected after a fault has
occurred resulting from this test, both LEDs flash alternately
(green/orange). This fault can only be reset by successfully
implementing the activation/diagnosis function procedure (elimi-
nate any faults or replace defective components).
