Abstract
Abstract A process for testing operational components in heaters, especially vehicle auxiliary heaters, in which the operational components are actuated and switched on sequentially, individually. Based on this, a corresponding evaluation is then performed. Further, a testing device for performing the process has a switching-on device with which the operational components can be started up, individually, on a sequential basis. From the process engineering viewpoint and from the device engineering viewpoint, further developments up to integration of the testing device in a heater control device are possible, and, optionally, for evaluation of the operational testing, external devices can also be used.
