Patent ID: 8430123

Claim:
A position regulator comprising: a travel measurement system; a regulation unit; a signal shaper fed via a conductor loop and being configured for outputting a travel-proportional conduction signal via the conductor loop and for receiving an alarm signal when the regulation unit is disrupted; a transmission path by which the signal shaper is connected between the travel measurement system and the regulation unit, the signal shaper being connected in series with the travel measurement system and in parallel with the regulation unit to transmit signals; and a switch of the signal shaper which is controlled by the alarm signal of the regulation unit, and having a first position wherein the travel measurement system is fed from the regulation unit, and having a second position wherein the travel measurement system is fed from the signal shaper, the signal shaper being automatically calibrated when the position regulator is activated by comparing an output signal from the travel measurement system with a travel signal which is received by the regulation unit.
