A short circuit is indicative of a lack of electrical resistance, removing the ability
to measure the impact from a change in voltage . This instance is largely driven
by an incorrect wiring setup . Verify that all wiring connections are attached in
the correct polarity, and that no signal and common wires are touching . Lastly,
ensure that the system is free of water and other contaminants .
State 3
- Input Open Detected
•
LED is solid red
An open circuit implies a physical disconnect somewhere on the electrical path
of the circuit . When receiving this error, verify that there is no physical separation
within the system, such as unattached or broken cabling . Be sure that the
connector is firmly secured to the accelerometer, and that the accelerometer is
in good working order .
State 4
- Device Warning Detected
•
LED is flashing green in one-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 one-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
