Abstract
An injection device has signal generators (11, 12, 13, 14) which are connected to operative elements (8, 3, 5, 4) of the device and which give off signals which represents the operative condition of the device. The signals are sent to an electronic circuit which controls a presentation of the operational condition of the device and presents operational conditions, which are defined as not allowed, as error indications by switching off the display presenting the operational condition of the device. The number of signals from each generator is counted and a number of operations exceeding a pre-set number for the signal generator in question is interpreted as representing a not allowed operational condition.
