ESD Control
An ESD signal can be connected to the actuator to override any existing command
and drive the valve to a predetermined position. The ESD control is not self-maintained:
the ESD action is only performed if the relevant input is active. The ESD control is active
when the 3-position selector is in REMOTE and no alarm is present.
!
WARNING
The user may select ESD to override the situations indicated by (*). If these situations
occur and if “ESD > ...” is configured, the actuator may be damaged. Therefore, selecting
“ESD > ...” will invalidate the warranty.
Function “ESD priority” allows the ESD command to override the following additional
situations: (*) motor thermostat alarm, (*) torque limit tripped, (*) local stop pressed,
3-position selector in local, 2-speed timer, (*) 3-position selector in OFF.
9.1.2
Torque Set-Up
The output torque limits to close or to open may be configured between 40% and 100% of
the nominal torque stated on the actuator nameplate.
