Why choose an actuator with an integrated
control ?
n
FOR ENGINEERINGS :
When conventional actuators equipped with
position limits, torque limiters and eventually a
proportional transmitter are integrated into a
process, complex electrical equipment must be
installed on site as follows:
l
Simplification and standardization of interface mod-
ules.
l
Makes it possible to choose important functions
before installation.
l
reversing starters,
control components,
l
n
FOR INSTALLATION OF ACTUATORS :
positioners,
l
Easy commissioning thanks to local controls.
l
optional control components,
l
Commissioning is possible with only the power
connected.
l
and so on ...
l
Time savings at commissioning.
l
It includes an additional important savings for :
l electronic board,
l start-up,
l dimensional,
l documentation,
l study.
The INTEGRAL+ includes an important cost savings
in controls because all of the control components are
integrated into the actuator.
n
FOR EASY USAGE :
Capable of modifying the control functions even dur-
ing usage.
l
Installation of additional functions on site at lower
costs.
l
Easy to use thanks to local settings and controls.
l
Local controls are lockable in various positions.

Integral + : a specific control for each need
REMOTE CONTROL
Control by means
of contacts:
• External power
supply
• Electronic board
with built-in power
supply (24V)
Control by pulse
signal :
• Only one pulse
required for open,
close or stop
Proportional
control :
• By current :
4-20 mA, 0-20 mA,
4-12 mA, 12-20 mA
• By voltage:
0-10 V
Command for local
bus control:
• Simple
• Redundant
3
Control by
maintained signal :
• Actuator continues to
function as long as
the signal is main-
tained and stops
when released
Control by pulse
signal :
• One pulse for open,
close or stop
Selector :
• Local / Remote
Lockable selector in
all 3 positions
• Remotely Allow or
Prohibit local controls

Motor temperature sensor:
maintained signal:
one pulse for open,
close or stop
Efficient protection for the motor against overheating.
If the temperature in the winding is too high, the motor
supply is stopped. Restarting is possible only after the
temperature decreases.
l
without maintained signal:
actuator continues to
function as long as the
signal is maintained
and
l
í
P3
Torque limiteur:
stops
when
released
The electronic board memorizes actions of the torque
limiter and prohibits restarting in the same rotational
direction. This system guaranties a complete full stop
even if the torque limiter pressure is released.

ESD: Emergency Shut Down for Open. or Close.
A fault signaling relay detects all malfunctions or unavail-
abilities and communicates this information remotely :
Power supply failure or blown fuse

Local control at the actuator:
Selector in "LOCAL" position

By maintained signal: actuator continues to function
as long as the signal is maintained and stops when
released

Possible choices between the following faults:
Torque limiter open / close tripped

Local / Remote / Off (stopping) selector lockable in all
3 positions

Timing control (optional)
This optional card will allow extension of the valve oper-
ation speed. The actuator operates by successive pulses
adjusted at the card. One part of the stroke can have a
normal operating speed and the other part an extended
speed control. An auxiliary limit switch gives the order to
switch from normal to slow speed. The adjustments are
independent in both open and close direction. The oper-
ating time for the full valve stroke can be set very long.
The device is used to avoid hammer effects when open-
ing and closing a valve.
- 4 options available from 16 possiblities
- 3 additional options can be added as an option:
Open/Close/Supply
Local (option):
- 3 LED's for Open/Close/Supply

Position transmitter: (with positioner)
Transmitting the proportional position signal is of the
same scale as the input control signal
Example
:
input 4-12 mA
output 4-12 mA
Exception :
input 0-10 V
output 0-20 mA
