Performing a Communication Test
►
Press the push-button (2) and hold it until you hear 2 successive signal tones and the status LED
flashes green 2 times.
►
Release the push-button.
After the push-button (2) is released, the radio communication path to the radio partner is checked.
A successful communication test is indicated both visually (status LED flashes green 2 times) and
acoustically (2 signal tones in succession).
NOTE
A successful communication test may require an adjustment of the current valve position.
If the communication test was not successful, this is indicated visually (status LED flashes red for
approx. 1 s) and acoustically (downward sequence of tones).
The radio small actuator switches to emergency mode.
NOTE
In case of an unsuccessful communication test, check the radio partner and the transmission path.
NOTE
If the communication with the radio partner is interrupted for longer than 1 h, the radio small actuator
switches to emergency mode (see page 5) and the “emergency mode” status bit (self-controlled
mode) is activated.
When a correct telegram is received, the radio small actuator automatically returns to normal
operation.
