Safety Safety System operation assumes knowledge of the operating instructions. Symbols Used The following symbols are used in these operating instructions: Indicates a hazardous situation which, if not avoided, may result in minor or moderate injury. Indicates a situation that may result in property damage if not avoided. Indicates a user action.
Safety Notes on CE Marking The following apply to the ACC5703: - EU Directive 2014/30/EU - EU Directive 2011/65/EU Products which carry the CE mark satisfy the requirements of the EU directives cited and the European harmonized standards (EN) listed therein. The EU Declaration of Conformity is available to the responsible authorities according to EU Directive, article 10, at: MICRO-EPSILON MESSTECHNIK GmbH &...
Functional Principle, Technical Data Functional Principle, Technical Data Functional Principle With the principle of an acceleration sensor, forces that change the velocity of an object are measured and transformed into an electric output signal. Therefore the sensor is mounted on the maneuverable component. The expected moves correspond to the measurement axes.

Delivery Delivery Unpacking, Included in Delivery 1 Sensor ACC5703 1 Operating Instructions Carefully remove the components of the measuring system from the packaging and ensure that the goods are forwarded in such a way that no damage can occur. Check the delivery for completeness and shipping damage immediately after unpacking. If there is damage or parts are missing, immediately contact the manufacturer or supplier.
Installation and Assembly Installation and Assembly Sensor Cable Assembly No sharp or heavy objects should be allowed to affect the cables. Avoid folding the cables. Do not bend more tightly than the minimum bending radius of the cables. > Damage or destruction of the cable, failure of the measuring device Do not crush the cable.

Installation and Assembly Configuration of Sampling Rate and Low- and High-pass Filter Parameters, like sampling rate or filter frequencies, are adaptable in a wide range in order to match the re- spective application. The high-pass is configured to reduce influences of low frequencies especially to hide earth acceleration. The low-pass is configured to hide disturbances at high frequency.
Installation and Assembly Different low-pass filter settings, see Fig. 15, cause the sampling rate to change respectively. The chosen low- pass frequencies furthermore have influence on the available high-pass filter options.

Operation Operation The measurement device is already calibrated when delivered. Calibration by the user is not necessary. After connection to the operating voltage, the sensor is immediately ready for operation and independently initiates the measurement. Additionally, the digital RS485 interface is ready to react to enquiries by the master (periodic retrieval of mea- sured data).

Appendix | Digital Interface RS485 A new sampled measurement value is saved to the internal buffer of the sensor. The maximum number of values which can be saved is 19 for each measurement axis. Therefore, an enquiry by the master must reach the sensor within a certain time, that depends on the set sampling rate, in order to read the content from the internal memory and ensure uninterrupted sampling (periodic enquiry).
