Emerson FloBoss S600+ - Troubleshooting Procedures

S600+ Instruction Manual
Revised July-2017 Troubleshooting 8-3
Note: The LED is orange while at the Startup menu. If it is still
orange when the configuration is running, contact your local
sales representative or technical support.
8.2.5 I/O LED
If the red or green LEDs on the backplate of the I/O module do not
blink while the S600+ is operating:
 Check the I/O module connections. Power down, remove and
reseat the I/O module, and then re-apply power.
 Check the front panel display and LED. If they are not lit, you may
have a power issue.
 Check with the person who configured the unit whether you have
the correct I/O module fitted.
 Check the running configuration for any BAD TX or BAD RX
messages. From the Main menu, select TECH/ENGINEER >
COMMUNICATIONS > SERIAL PORTS > PORT 08.
8.2.6 I/O Fail Messages
If the front panel displays an I/O Fail message:
 Check the jumper settings on the I/O modules.
 Check the I/O field wiring connections.
 Check that the I/O modules are seated and secured.
8.2.7 Serial Communications
If you are experiencing troubles with a serial communications
connection (RS-232, RS-422, or RS-485):
 Check to make sure power is applied to the S600+.
 Check the wiring to the termination block or connector. Refer to
Chapter 3, CPU.
 Check the communication port settings from the front panel
display.
 Check the Modbus address.
 Check the setting of the termination resistor jumper.
8.3 Procedures
Initiate a cold start after you send a new configuration to the S600+ or
to recover from extreme situations, such as a corrupted database. A
cold start builds a new metering database, using the configuration data
stored in the S600+’s flash memory.
Note: You must perform a cold start if you update or otherwise
change the firmware.
