Abstract
A method () for testing of a door operator (), the door operator () being configured to via a mechanism () move at least one door leaf () between a first position and a second position. The door operator () includes a first drive unit () configured to optionally move the door leaf () into said first position and a control unit () connected to a sensor (). The method includes the steps of initiating a simulated powerless mode, measuring operation of the door leaf by the sensor, and comparing measured values of movement with reference values.
