14.7 ESD in degraded mode
Protection devices are active in the standard configuration and therefore
halt the operation of the actuator if a fault occurs.
It is possible to allow the actuator to deliver up to 100% of its nominal torque
to ensure fault-tolerant operation if an emergency command is given (see
description of auxiliary commands 1 or 2).
It is also possible to by-pass the motor thermal protector (risk of motor
damage).
Select change in the menu and
turn to OK to confirm.

Select fault tolerance ESD in
the COMMANDS menu and turn to OK to confirm.
When an option is selected, the brackets are removed, and an
asterisk is displayed in front of the selected item.
Turn to OK to cancel selection.
14.8 Partial stroke
Partial stroke test allows to operate from time-to-time motorized valves
that are rarely used to check that they remain fully operational if needed.
This test consists of rotating the valve of a certain portion of the stroke
(e.g., 10% of full travel) and then returning it to its original position. The
duration of this travel is monitored, and an alarm is activated if the specified
time is exceeded.
You can run this test using remotely or locally (Local PST).
14.8.1 Shared settings
They can be set at Change > Commands > Partial stroke
•
Start pos.: select if the test shall start from an open or a closed valve
position. If the start position is not the one selected, then a warning
«Partial Stroking Default» is sent out.
•
Stroke%: set the travel in % for the partial stroking (default value
10%)
•
Operating time: input the full stroke time in seconds then the shared
parameters (see §14.8.1).
