Configuration parameters for firmware version 2.1
The TLC-BCR-T can be adapted to wide variety of applications. The adaptation is done with parameters. The
parameters can be changed on the unit without the need of additional equipment.
Identifying the firmware version
The parameters and functionality of controller depend on its firmware revision. It is therefore important to use a
matching product version and parameter set. The firmware version is shown on the large LCD digits when pressing UP
and DOWN buttons for more than 3 seconds simultaneously.
Control Parameters (Access Code: 241)
Warning! Only experts should change these settings! See user parameters for login procedure.
