3.4.3 Error behavior

The device has different error behaviors depending on the measuring characteristics and on the start operation.
3.4.3.1 A - Behavior
In case the device detects an error, this error is signalized at the outputs. On the serial and SSI output the error code will be visible
depending on the configuration. The error will be visible at the output until the device performs a successful measurement and outputs the
new distance value or the device will be reset by command (sNc) or by a power cycle.
3.4.3.2 B – Behavior (in moving target characteristic)
This error behavior is only relevant when using the moving target measurement characteristic.

The error reset function depending on the start condition. The following diagram shows the error reset for the different start configurations.
Stand-alone mode: Auto start configuration
(3.3.2.1 Auto start configuration on page 11)
In this operation the measurement starts automatically at power on.
A signalized error is reset automatically after 5 seconds. The reset is
done by an automatic restart of the device. This restart maximal
takes about 4 seconds.

condition is cleared (a successful measurement is
done).
The permanent error must be reset as described
below.
Stand-alone mode: Manual start configuration
(3.3.2.2 Manual start configuration on page 11)
In this operation the measurement is started with a digital input. In
case of an error, the reset of a signalized error is done by restarting
the measurement with the digital input.
