BLOCKSYSTEM FA 6 REV. 02 02/03
UK
7. 4
HOW TO CHANGE THE PARAMETERS
A fixed set of parameters in the memory of the controller regulates the function of the Blocksystem.
(acc.to schedule). We recommend only to change these values when necessary by experts.
To enter the programming menu, press the „SET“key for more than 5 sec. The label of the
parameter appears. To scroll through the other parameters, use the “UP” and “DOWN” keys. To
change the parameter, press and relese “SET”. Then set the desired value with the “UP” and
“DOWN” keys, and confirm with the “SET” key to move to the next parameter
.
