| 摘要 |
The invention pertains to a field unit (10) for mounting on an actuator (12) with a pickup device (14) in the field unit (10) to register the position of the actuator (12) and with an indicator (16) located correspondingly on a movable element (15) of the actuator (12) to indicate the position of the actuator (12), where, when the field unit (10) is mounted on the actuator (14), the pickup device (14) of the field unit (10) can be linked with the indicator (16) of the actuator (12). The invention is characterized in that the pickup device (14) of the field unit (10) is in working connection with a locking element (18), and in that the pickup device (14) can be held by this locking element (18) in a first position-the mounting position-and can be released from the mounting position by the actuation of the locking element (18).
