XX�X = display value
A = binary value
P1: position 1, e�g� maximum value reached; P2: position 2, e�g� upper preset value reached;
P3: position 3, e�g� lower preset value reached; P4: position 4, e�g� minimum value reached
The binary mode corresponds to an analogue evaluation with a resolution of 6�6 %
of the active zone or 4 bits�
In the evaluation electronics (PLC etc�) no analogue input is used, the analogue
value is already available in digital form (8-4-2-1 binary code)�
