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�
The factory configuration is the following:
action: CLOSE, signal type: PRESENT,
priorities: ESD > LOCAL CONTROLS,
ESD > 2-SPEED TIMER, ESD < all other cases�
9.1.3 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�
9.1.4 remote controls
The actuator may be remotely controlled by 4,
or 3, or 2 wires depending on the connection
made on the terminal board of the actuator�
The following options are available:
- 4 wires latched: requires 2 momentary
signals (since the control is self-maintained)
to open or close and one signal to stop in
mid-travel� The action of the stop signal can
be reversed (stop when signal is On [MAKE]
or stop when signal is Off [BREAK]).
- 3 wires latched instant reverse: requires
2 momentary signals (since the control is
self-maintained) to open or close� Reverse
momentary signal reverses the direction�
- 3 wires momentary: requires 2 push-to-run
type signals (since the control is not
self-maintained) to open or close�
- 2 wires open if signal On: requires signal On
to open and no signal to close�
- 2 wires open if signal Off: requires signal Off
to open and signal On to close�
By selecting the option Off, the remote controls
are disabled�
Configuration should be done during actuator
set-up�
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 Remote
controls�
- Local selector in LOCAL� Choosing
ESD > LOCAL CONTROLS, the ESD
action will be carried out also when the
local selector is in LOCAL� Vice-versa, if
ESD < LOCAL CONTROLS was chosen,
the ESD action will not be performed if the
3-position selector is in LOCAL�
- 2-speed timer� Choosing ESD > 2-speed
timer, the 2-speed timer function will be
inhibited during ESD action� Vice-versa,
if ESD < 2-speed timer was chosen, the
2-speed timer function will be active during
ESD action�
- (*) Local selector in Off� By choosing
ESD > Off, the ESD action will be carried
out also when the local selector is in Off�
Vice-versa, if ESD < Off was chosen, the
ESD action will not be performed if the
3-position selector is in Off�
• Press YES if the control mode is correct or
NO to scroll the list of available options:
4 wires, 3 wires, 2 wires, off� Press yES to
select the desired option� If 4 wires was
chosen use yES and NO to select the STOP
signal: set MAKE to stop when signal is on
and set BREAK to stop when signal is off.
If “3 wires” was chosen, use yES or NO to
answer the prompt on the display and choose
among “push-to-run” or “latched instant
reverse” control modes� If “2 wires” was
chosen, use yES and NO to choose among
“open if signal ON” or “open if signal Off”
control modes�
