Service and troubleshooting
Action
• Check that there are two terminators on
the Tankbus. Normally the built-in
termination in the Rosemount 2410 Tank
Hub is enabled.
• Check that terminations are placed at
both ends of the Tankbus
• Check that the total current consumption
of the devices on the Tankbus is less than
250 mA. See the Rosemount 2410
Reference Manual (Document no.
00809-0100-2410) for more information.
• Remove one or more devices from the
Tankbus. The Rosemount 2410 Tank Hub
supports a single tank. The multiple tank
version of the Rosemount 2410 supports
up to 10 tanks.
• Check that the right field port on the
Rosemount 2460 System Hub is
connected to the Primary bus on the
Rosemount 2410 Tank Hub.
• Check communication port LED:s inside
the Rosemount 2460 System Hub.
• Check the Modbus communication
address specified for the appropriate ATD
device, i.e. the device that represents the
Rosemount 2240S Multi-input
Temperature Transmitter in the system
hub's tank database. For the single tank
version, this address is equal to the
Modbus address of the Rosemount 2410
Tank Hub itself.
• Check configuration of communication
parameters for the Rosemount 2460
System Hub field ports.
• Check that the correct communication
channel is selected.
See the Rosemount Tank Gauging
Configuration Manual (Document no.
00809-0300-5100) for more information on
how to configure the system hub.
