7.16.1 Torque monitoring
The torque monitoring serves as overload protection over the whole travel.
Depending on the version, the required tripping torques are either set via
the torque switching in the actuator or via the
OPENING and CLOSING
parameters (Non-Intrusive version).
If the set torques are reached in mid-travel, the actuator will be stopped
and the following fault signals will be sent:
.
Status indication S0: operation mode OFF/LOCAL = FLT+NR
.
Status indication S0/S6 : operation mode REMOTE = FAULT IND.
.
Status indication S1 : TORQUE FAULT (OPEN) or TORQUE FAULT
(CLOSE)
(torque fault)
The fault has to be acknowledged before the operation can be resumed.

via the Reset push button in selector switch position LOCAL
.
or via the Profibus, Reset Bit of process representation (for this, the
selector switch must be in Remote control position).
Setting the torque by-pass
The torque monitoring can be disabled during the set torque by-pass dura-
tion.
For this period, the torque by-pass is effective, irrespective of the actuator
position.
