5.2 Change to the cut-off point
ATTENTION
If, when lifting the test load during initial commissioning, an overload is not detected or
the maximum lifting capacity cannot be lifted, a new cut-off point must be saved in the
device.
This change may only be made by an electrically skilled person with the help of the
testing bay function . The permissible setting range must be observed here.
Permissible setting range of the overload cut-off point:
Overload cut-off points between 12 and 30 mV can be set with the SLE 3. This corre-
sponds to a HEX switch setting from the minimum value: S4 = 4 and S2= B (minimum
value) to the maximum value: S4 = C and S2 = 2.
ATTENTION
If the sensor value at 110 % of the maximum lifting capacity is greater or smaller than the
permissible range and a load sensor fault can be ruled out, a larger or smaller load
sensor must be used.
5.3 Settings
5.3.1 Testing bay function
WARNING
The testing bay function involves the setting and saving of an overload cut-off point in the
SLE 3. Errors in the activation sequence or when saving a new overload cut-off point can
lead to dangerous situations up to falling of the load. The testing bay function may
therefore only be used by an electrical qualified person.
Label on the inside of the front panel
Changes to the cut-off point must be documented in this manual in the section
“Documentation of changes to the cut - off point” and in the crane logbook, stating
the reason, and signed by the setter and operator. The new cut-off point must also
be noted on the label in the cover (see figure).
Preparations for activation of the testing bay function:
The following preparations should be made or organized before activating the testing bay
function:
•
Get a test load of 110 % of the maximum lifting capacity ready.
•
Get a load weighing the maximum lifting capacity ready.
•
Carefully take off the front panel (device cover) of the SLE 3 with the help of a
screwdriver and put in a safe place.
