Testing the Power Modules
At none of the tests the reading should indicate 0 Ohm. If only one of the tests
shows deviating readings the power module must be replaced (the replacement
is to be performed only by KEB).

Prior to delivery all products pass several quality and performance inspections so
that malfunctions can be ruled out. When used in accordance with the operating
instructions failure is most unlikely.
However, if you have cause for complaint the unit should be returned stating
invoice number, delivery date, cause of failure and field conditions. We do not
accept the responsibility for failures due to misuse, wrong storage or similar
causes.
Leaflets, catalogues and quotations contain only standard values.
We reserve the right to make technical changes without obligation.
