16.6 OPEN OR CLOSE PRIORITY
There are no priorities on open or close in the standard configuration. Priorities are used to reverse
the direction of travel when an action is in progress without having to give a stop command. In this
case, priority must be given to open and close actions.
Assign priority to one direction of rotation: if the opening action is assigned priority and the actuator
receives an open and a close command simultaneously, the actuator will open. See §16.1 for making
single contact commands.
Select change in the MENU and turn to OK to confirm.
Select commands in the CHANGE menu and turn to OK to confirm.
Select priority in the COMMANDS menu and turn to OK to confirm.
Select (open), (close) or (open and close) and turn to OK to confirm.
16.7 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-tole-
rant operation if an emergency command is given (see descrip-
tion of auxiliary commands 1 or 2).
Select change in the MENU and turn to OK to confirm.
Select commands in the CHANGE 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.
16.8 PARTIAL STROKE
It may be useful to operate motorised valves which are rarely used from time to time to ensure that
they remain available for service.
INTELLI+ has the ability to test actuator functions when requested by the user. This test consists
of rotating the valve a certain distance (e.g. 10% of full travel) and then returning it to the original
position. The time taken to travel the distance is monitored and an alarm is activated if the specified
time is exceeded.
The user gives this command using an auxiliary input on the actuator (see configuration informa-
tion). The test runs automatically. Signals - partial stroke in progress and partial stroke fault, need
to be configured on two relays.
