1 Safety Information
Intended Use
The usage of this device within a machine or system is permissible under the following conditions:
The user must possess expertise in designing and employing functional safety sensors.
•
•
The user has acquired knowledge of both the Datasheet, the User Manual and the
Declaration of Conformity.
•
The device should only be used in environmental situations covered by the datasheet.
The device is mounted correctly as described in the datasheet and user manual.
•
•
Given the accelerometer-based nature of this device, its sensitivity to
accelerations/vibrations necessitates application-specific testing to to ascertain its
compliance with customer requirements.
•
The zeroing function and configuration using the QG40N configuration tool should only be
undertaken by authorized personnel, in the correct position. The Manufacturer disclaims
responsibility for any damage resulting from customer settings, even when employing
manufacturer defaults.
•
Bandwidth settings (filtering) are set according to the application requirements.
•
Configuration of the Tilt switch device, including changing switch points, filtering, etc., can be
done using the optional QG40N configurator. The customer is responsible for ensuring only
authorized / trained personnel do this configuration. The manufacturer is not responsible for
these configuration changes.
The proof test interval (mission time) for this sensor is 20 years. After this interval,
•
replacement or assessment by comparing the output to a reference sensor, or
checking/recalibrating by the manufacturer is advised. This step aims to identify non-
detectable faults and/or degradation. Note that this check/recalibration is not covered
within the product's initial purchase price.
•
This sensor does not require any maintenance between proof-test intervals.
Sensor Defective
The sensor is considered "defective" when
The output of the device is non-conductive, resulting in a 'low' state due to the external pull
•
down resistor.
•
If two outputs are used, the device will be considered as 'unsafe' even if only one output is
non-conductive.
If any damage is noticed the device must be replaced by a new one in order to avoid hazard.
By ignoring the safety information the manufacturer cannot be hold responsible for any damage
or hazard. For uncertainties, contact the distributor or manufacturer. Unauthorized modifications or
usage voids the warranty and manufacturer liability.
