• Visible in the livelist 10 seconds after the Bluetooth search commences
• Data can be read from the Bluetooth module 60 seconds after the supply voltage is switched on
• Display of the current vibration frequency and the switching state of the device
The yellow LED flashes when the Bluetooth module is connected to another Bluetooth device, e. g.
mobile phone.
Heartbeat Technology
 Additional details in the "Application packages" section.
Heartbeat Technology
The electronics module and the tuning fork are checked using Heartbeat Technology, and a
verification of the Liquiphant is performed. The switch output is not changed during this test. The
test can be performed at any time and does not influence the switch output in the safety circuit. In
the case of proof-testing, the SmartBlue app supports users in every step of the test. The switch
output is also switched during this test. During the proof-test, alternative monitoring measures must
be taken to ensure process safety.
Proof test
During the proof test, the SmartBlue app provides support for each individual stage of the test
(proof-test wizard). The switch output is also switched during this test. During the proof test,
alternative monitoring measures must be taken to ensure process safety.
Evaluation of the vibration frequency
If the vibration frequency exceeds the upper warning frequency, a warning is displayed. A warning is
activated when the fork becomes corroded, for example. The switch output remains in the current
state. The warning is displayed in the SmartBlue app and output in the Heartbeat Technology
protocol. When a warning occurs, it is necessary to check the Liquiphant sensor.
The current oscillation frequency must be in the range between the upper and lower alarm
frequency. If the current oscillation frequency is above the upper alarm frequency or below the lower
alarm frequency, an alarm is output. The output switches to the safety-oriented state.

Certificates and approvals

The certificates, approvals and other documentation currently available can be accessed as
follows:
Endress+Hauser website:
The measuring system complies with the statutory requirements of the applicable EC Directives.
These are listed in the corresponding EC Declaration of Conformity along with the standards applied.
Endress+Hauser confirms successful testing of the device by affixing to it the CE mark.
The supplied product or measuring system meets the ACMA (Australian Communications and Media
Authority) requirements for network integrity, interoperability, performance characteristics as well
as health and safety regulations. Here, especially the regulatory arrangements for electromagnetic
compatibility are met. The products are labelled with the RCM- Tick marking on the name plate.
All data relating to explosion protection are provided in separate Ex documentation and are available
from the Downloads Area. The Ex documentation is supplied as standard with all Ex devices.
