Push button
Pressing the push button executes a range of functions depending on how long the button is actually
pressed. A power supply unit must be connected.

Resetting the configuration
to the default settings
Prerequisite: The power supply unit must be disconnected.
1. Press the push button.
2. Press and hold the push button and reconnect the power supply unit. The red LED is lit.
3. Press and hold the push button for 10 to 15 seconds. The red LED flashes at 2.5 Hz. The
configuration is reset to the manufacturer's default settings.
Resetting the configuration
and firmware to the default
settings
Prerequisite: The power supply unit must be disconnected.
1. Press the push button.
2. Press and hold the push button and reconnect the power supply unit. The red LED is lit/flashes
at 2.5 Hz/is lit.
3. Press and hold the push button for 20 to 25 seconds. The red LED flashes at 1.25 Hz. The
firmware and configuration are reset to the factory settings.
6.1.2
Display
If the push button is pressed briefly, the three light emitting diodes indicate the current status.
Yellow light emitting diode:
communication status
Time pressed
Function
≤
0.2 s
No function
> 0.2 to 5 s
LEDs light up to indicate the status of the adapter (see Chapter 6.1.2)
– When the adapter attempts to join the network, the LEDs continue to indicate
the status until the connection has been made.
5 to 10 s
Joins the adapter to the wireless network
– Once the button has been pressed for 5 seconds, the yellow light emitting
diode flashes at 3 Hz
10 to 15 s
Activates the mode for configuring the connected field device
– Once the button has been pressed for 10 seconds, the red light emitting diode
flashes at 3 Hz
– If HART communication does not take place in the configurable time frame
(e.g. 300 seconds), or if the push button is pressed again for 10 to 15 s, the
user quits the mode for configuring the connected field device. The red light
emitting diode goes out.
> 15 s

Communication status Meaning
Lit
Connected, alternative
path
1)
Adapter is connected to the network
– An alternative communication path exists
Flashes at 1 Hz
Connected, no
alternative path
1)
Adapter is connected to the network
– An alternative communication path does not exist
Flashes at 3 Hz
Joining
Currently attempting to join the network, e.g. for 40
min once the battery unit is connected
– The length of the joining period can be configured.
Off
Not connected
The device has not joined the network
1) Alternative communication path: information is sent by a neighboring adapter.
