Default LED status light setting

 

The HF5A has per default 3 different status LED light colors, which are indicating 3 different statuses.

 

Green stands for normal operation:

 

 

Orange stands for simulation mode:

 

 

 

Red stands for error mode:

 

 

Based on the model, LED lights behave as follows:

 

•2-wire version: only a flashing light;

•3/4-wire or digital version: permanently illuminated.

 

 

Detail LED flashing pattern

 

In addition to the standard status lighting, the HF5A offers a special flashing pattern (particularly useful for devices without a display), which can provide the user with more detailed error descriptions. This function is disabled by default but can be activated through the HF5A configuration menu.

 

The flashing LED patterns are divided into two categories:

 

•Probe Errors:  Errors related to the connected sensor, that must be resolved before the device can resume the regular operation;

•Serious Errors: Errors preventing the regular operation of the device.

 

The tables below provide an schematic overview of the flashing LED patterns according to their respective error messages.
