State 4
- Device Warning Detected
•
LED is flashing green in 1-second intervals
A detected warning can be due to several things, such as incorrect output wiring
(e .g ., an open circuit detected on a current output or a short circuit detected
on a voltage output) or corrupted configuration memory . The device will still
be processing input data . However, it may be running in a reduced state or
return unexpected results (e .g ., if memory is corrupted, the unit will default to
the standard ISO configuration until reprogrammed) . If this state is detected,
carefully inspect all wiring for secure connections and cycle power to the device .
If the warning persists, the configurator can be used to determine the root cause
and corrective action .
State 5
- Fatal Error
•
LED is flashing red in 1-second intervals
In the case of a fatal error, the device has detected some non-recoverable
hardware issue which could have been caused due to physical damage or misuse .
Processing will be disabled in this case . Communication with the configurator
may or may not work depending on the root cause but should be attempted as
it may state the error that occurred . In some cases, cycling power to the device
can remedy the issue .
State 6
- Programming and Startup
•
LED is solid orange
This state occurs when the signal conditioner starts up, confirms there is an
available configuration, and sets up its peripherals and outputs . If the USB cable
is connected and plugged into a PC, this state will persist . Plugging in the USB
cable at any point will also cause the device to enter this state . Regular operation
will not occur while the USB cable is plugged in .
State 7
- Bootloader
•
LED is flashing between red and green
This state occurs during device startup and indicates the bootloader is running .
This state will persist if new firmware is being written for the duration of the
update . If no firmware update handshake is received from the configurator within
5 seconds, the device leaves this state and continues with the startup .
