A.6 Communication card function description
A.6.1 Bluetooth communication card––EC-TX501
Indicator definition
This indicator is on when the extension card is
establishing a connection with the control board;
it blinks periodically after the extension card is
properly connected to the control board (the
period is 1s, on for 0.5s, and off for the other
0.5s); and it is off when the extension card is
disconnected from the control board.
Bluetooth
communication state
indicator
This indicator is on when Bluetooth
communication is online and data exchange can
be performed.
It is off when Bluetooth communication is not in
the online state.
This indicator is on after the control board feeds
power to the Bluetooth card.
The EC-TX501 communication card is especially useful for scenarios where you cannot directly use
the keypad to operate the inverter due to the restriction of the installation space. With a mobile phone
APP, you can operate the inverter in a maximum distance of 30 m. You can choose a PCB antenna or
an external sucker antenna. If the inverter is located in an open space and is a molded case machine,
you can use a built-in PCB antenna; and if it is a sheetmetal machine and located in a metal cabinet,
you need to use an external sucker antenna.
When installing a sucker antenna, install a Bluetooth communication card on the inverter first, and
then lead the SMA connector of the sucker antenna into the inverter and screw it to CN2, as shown in
the following figure. Place the antenna base on the chassis and expose the upper part. Try to keep it
unblocked.
