1.3 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
Configuration procedure:
• Move the local selector to OFF and then simultaneously press OPEN and STOP. Select
the language and then enter the password according to the instructions (see “Entering the
set-up mode”). When the message displayed is “SET-UP MODE OK?” press YES. Press
YES to select actuator set-up menu, press NO to scroll the list of available routines and
then press YES to select ESD set-up.
• Press YES if the ESD action is correct, or press NO to scroll the list of available options
(off, open, close, stay-put, go to position xx %). Press YES to select the desired option.
• Press either YES or NO to select the signal type (present, absent)
• Press YES to change ESD priority with reference to the following signals or status:
• (*) motor thermostat alarm. Choosing ESD > THERMOSTAT, the ESD action will be
carried out also in case of motor over-heating. Vice-versa, if ESD < THERMOSTAT was
chosen, the ESD action will not be done in case of motor over-heating.
• (*) torque limit tripped. Choosing ESD > TORQUE LIMIT, the ESD action will be carried out
also in case of torque alarm. Vice-versa, if ESD < TORQUE LIMIT was chosen, the ESD
action will not be done in case of torque alarm.
• (*) local stop pressed. Choosing ESD > LOCAL STOP, the ESD action will override the
local STOP signal. Vice-versa, if ESD < LOCAL STOP was chosen, the ESD action will not
be performed if the local STOP push-button is pressed.
