Abstract

The invention relates to a leakage indication device for monitoring the pressure of a monitoring space (3). The leakage indication device comprises a pressure element (21) and at least one fluid connection to an ajustable multi-way valve (13, 26), which has a leakage indication operating position, in which the pressure element (21) is connected to the monitoring space (3) for the monitoring thereof. Furthermore, the multi-way valve (13, 26) has at least one non-leakage indication operating position. The leakage indication device also has at least one multi-way valve faulty position detecting means for detecting the at least one non-leakage indication operating position of the multi-way valve (13, 26) of the leakage indication de- vice.
