Description
1
The orange LED is flashing when the PC communicates with PC Tool Link.
Otherwise, the LED is off.
2
The two red LEDs indicate communication to and from the PC.
3
The two red LEDs indicate communication to and from the Grundfos product.
4
The three yellow LEDs indicate whether an RS-485 or TTL cable is
connected. RS 232 is currently not in use.
The RS-485 LED is on when the RS-485 cable is connected to PC Tool Link.
The TTL LED is on when the TTL cable is connected to both PC Tool Link
and the Grundfos product.
5
The green LED indicates that PC Tool Link is powered.
6
The orange LED (pos. 1) and the four red LEDs (pos. 2 and 3) are flashing
while the PC communicates with the Grundfos product.
7
When the orange LED (pos. 1) and the two red LEDs (pos. 2 and 3) are
flashing, data is transmitted from the PC to the Grundfos product.
8
When the orange LED (pos. 1) and the two red LEDs (pos. 2 and 3) are
flashing, data is transmitted from the Grundfos product to the PC.
