9.1.13.5 torque by-pass (%)
Since a high torque may be required to unseat
certain valves, the torque by-pass routine
masks the torque alarm when an open or
close command is received and the actuator
is fully open or closed� The torque by-pass is
expressed in % of position and is configurable
from 0% to 20%. For example, if a 10% by-pass
value is set, we may have:
- by-pass active in Opening: from 0% to 10%
- by-pass active in Closing: from 100% to 90%
To exclude torque by-pass configure 0%.

9.2 ValVe data
The valve data allow identifying the valve and its
function in the process� The valve manufacturer
and the end user can enter the data� The
following data can be entered:
- Tag name (max� 28 characters)
- Serial number (max� 28 characters)
- Manufacturer (max� 28 characters)
- Break OP torque (max� 28 characters)
- Break CL torque (max� 28 characters)
- Max stem thrust (max� 28 characters)
- flange type (max� 28 characters)
9.1.13.6 Valve jammed (time)
The valve jammed time is used to monitor the
following situations:
1� The time passed after receiving an open
or close control is greater than the “valve
jammed time”, but the valve position
variation is smaller than 0.5%. The motor
is blocked, the command is cleared and
the “valve jammed” alarm indication is
generated�
2� The valve is moving, but during the travel the
position valve variation is smaller than 0.5%
in a time equal to “valve jammed time”� The
motor is blocked, the command is cleared
and the “mid-travel alarm” indication is
generated�
The valve jammed time is expressed in seconds
and can be configured from 0 to 100 sec�
Configure “0” to exclude the routine�

9.1.13.4 lithium battery
On request, the actuator can be provided with
a lithium battery to update the remote outputs
(output relays status and bus messages) in
case of electrical power failure and manual
override operations� The program runs the
functions relevant to the battery only if the
appropriate flag “lithium battery” is configured
with “present”� If the battery is absent or if no
updating of remote outputs is requested, the
above flag should be configured with “absent”�
