Patent ID: 8313083

Claim:
An electropneumatic position regulator for controlling a pressure-medium-operated actuating drive, the position regulator comprising: a working connection configured to apply compressed air to the actuating drive; a feed pressure connection configured to receive the compressed air; an electronic control unit configured to assume a safety position in the event of a fault, the electronic control unit being integrated within a housing of the position regulator; a downstream signal output unit configured to, upon the electronic control unit assuming the safety position, to generate at least one binary fault signal; and at least one signaling device configured to transform the at least one binary fault signal into a signal perceivable outside the housing of the position regulator, wherein the at least one signaling device is configured to transform the at least one binary fault signal into at least one of an audible and a visual signal perceivable outside the housing of the position regulator, wherein the electronic control unit is configured to assume a fault-dependent safety position in a zero-current state of an electropneumatic switching mechanism for switching the compressed-air flow, and wherein the electronic control unit is configured to make all available electrical energy from the assumed fault-dependent safety position for operation of the at least one signaling device.
