Discover the new PROFOX in 360°
The position indicator signals the valve position through its rotating indication. During commissioning, the position indicator must be adjusted to the valve position. For the part-turn actuator type, three versions are available for different swing angles or swing angle ranges: 90°, 120° and 45° through 360°. The indication rotates in horizontal direction. For the multi-turn actuator type, the valve position is shown in vertical direction with up to max. 27 turns per stroke. The display travels vertically.
The actuator is equipped with a handwheel to ensure manual operation or emergency operation. On request, the actuator can be supplied without handwheel function.
PROFOX has a modular platform concept. The output drive housing with the integrated combination of spur wheel and planetary gearing varies depending on the speed and type of motion. PROFOX is already available as part-turn and multi-turn actuator. The linear actuator version will follow at a later stage.
As standard, PROFOX is equipped with electronics for motor control and basic communication to the DCS. Two additional slots are available for inserting further boards, e.g. to allow communication via fieldbus. Boards for Ethernet protocols as well a a board with additional I/O contacts are planned. A firmware update is possible using the USB port.
PROFOX allows local end position setting using four push buttons. The LED located left of the push buttons indicates the respective status.
- End position OPEN is set once the LED is illuminated in green.
- Operation into end position OPEN is indicated when the LED is blinking in green.
- End position setting is possible once the LED is blinking in blue.
- End position CLOSED is set once the LED is illuminated in red.
- Operation into end position CLOSED is indicated when the LED is blinking in red
Different colours and lighting patters (blinking/flashing, illumination) are used for the FOX-EYE indication light to signal operation direction, end position, functionality or faults.
PROFOX operation is comfortable via smartphone or AUMA Assistant App (for Android devices) or via the AUMA CDT software (Diagnostics & Commissioning Tool in the latest version) via notebook or tablet. All parameters for configuration can be read and modified using the App. The selected user level determines which parameters can be changed by the user. Furthermore, diagnostic information and operational data of the actuator can be downloaded and displayed.
