Solution
Solution Solution
Check the Modbus wiring between the Supervisor
Module and the fiber to serial converter.
• A = GND
• B = Data B(+) – Blue/White
• C = Data A(-) – White/Blue
Verify the fiber port setup. See
Modbus (RS-485) Wiring, page
• RX from ADCM Port 1 is connected to Fiber to Serial
Converter TX.
• TX from ADCM Port 2 is connected to Fiber to serial
Converter RX.
Verify the fiber cable setup. See
Tank Control Modules to the Supervisor Box, page
Check all parameters for your version (Lenze
SMVector or Allen Bradley PowerFlex 4M). See
Digital Input Configuration, page
Verify the wiring. See Wire the Variable Frequency
Drive/Inverter to the Supervisor Module, page
Turn on node communication. See
Turn on Node Communication, page
Verify that the Radar Level Sensor (M, T) is connected to
the correct port. See Connect a Radar Level Sensor to a
Pump Control Module or Tank Control Module, page
Make sure the box is enabled to turn on power in the
setup screens. See Connect a Radar Level Sensor to a
Pump Control Module or Tank Control Module, page
Verify that the IP address settings for Port 2 are correct.
See Network Setup and Configuration, page
