Notice
The corresponding torque switch must not respond before the associated
limit switch when the torque switch TO (OPEN) and/or TC (CLOSED) is
connected. In this case, the positioner is switched off immediately with the
fault message "Trip - Blocked positioner".
If both limit switches respond at the same time (FO=1 and FC=1), the
positioner is immediately switched off via the fault message
"Trip - Double 1".
If both torque switches respond at the same time (TO=0 and TC=0), the
positioner is switched off immediately with the fault message "Trip - Double
0".
If the end position feedback does not correspond to the control command,
the positioner is switched off with the fault message "Trip - End position
fault".
