DESCRIPTION
These electric actuators have been designed to perform the control of a valve with 90° rotation. Please consult us for any different appli-
cation. We cannot be held responsible if the mentioned actuators are used in contradiction to this advice..
TRANSPORT AND STORAGE
 The forwarding agents being held as responsible for damages and delays of the delivered goods, the consignees are obliged to ex-
press if applicable their reserves, prior to accept the goods. The goods delivered directly ex works are subject to the same conditions.
The transport to the place of destination is carried out by using rigid packing material.
The products must be stored in clean, dry, and ventilated places preferably on appropriate palettes or shelves.
MAINTENANCE
 Maintenance is ensured by our factory. If the supplied unit does not work, please check the wiring according to the electric diagram as
well as the power supply of the concerned electric actuator.
For any question, please contact our after-sales service.
 To clean the outside of the actuator, use a lint and soapy water. DO NOT USE CLEANING PRODUCT WITH SOLVENT OR ALCOHOL
SAFETY INSTRUCTIONS To be read prior to the installation of the product
 The electric power supply must be switched-off before any intervention on the electric actuator (i.e. prior demounting its cover or ma-
nipulating the manual override knob).
 Any intervention must only be carried out by a qualified electrician or other person instructed in accordance with the regulations of
electric engineering, safety, and all other applicable directives.
 Strictly observe the wiring and set-up instructions as described in the manual: otherwise, the proper working of the actuator can not be
guaranteed anymore. Verify that the indications given on the identification label of the actuator fully correspond to the characteristics of
the electric supply.
 Do not mount the actuator « upside down ». Risks:
 Declutching mechanism failure
 Possible flow of the grease on the electronic board
 Do not mount the actuator less than 30 cm of a electromagnetic disturbances source.
 Do not position the equipment so that it is difficult to operate the disconnecting device.

Emergency manual override
The priority functioning mode of this actuator is electric. Be sure than the power supply is switched off before using the manual
override
1. Turn the knob to position MAN (counter-clockwise) and hold it in position.
2. Turn the outgoing drive shaft of the actuator with the help of an adjusting spanner.
3. In order to re-engage the reduction, release the knob (spring return).

Electric wiring
 As stipulated in the applicable regulation, the connection to earth contact is compulsory for devices with working voltages exceeding 42V.
 The actuator is always powered, so it must be connected to a disconnection system (switch, circuit breaker) to ensure the actuator power
cut, correctly located, easily reached and marked as being the disconnecting device for the equipment.
 An Inrush current may occur when actuators are switched on. Therefore it is necessary to limit the number of actuators on the same line.
Alternatively an inrush current limiter at the output of the circuit breaker may be used.
 The terminal temperature can reach 90°C
 For a use with a long power supply wiring, the induction current generated by the wires mustn't be higher than 1mA
 In order to ensure the IP65 tightness, the cable gland for feedback wiring must be used (7 to 12mm cable). Otherwise, the cable
gland must be replaced by a ISO M20 IP65 cap.

Instructions
Our cable glands are designed for cables with a diameter between 7mm and 12mm.
The actuator can support MAINS supply voltage fluctuations up to ±10 % of the nominal voltage.
It is necessary to connect all actuators to an electrical cabinet
 Remove the position indicator, unscrew the four screws and take off the cover.
SUPPLY AND CONTROL WIRING
 Ensure that the voltage indicated on the actuator ID label corresponds to the voltage supply.
 Connect the wires to the connector in accordance with the required control mode. (see diagram p.15)
WIRING OF THE FEEDBACK SIGNAL
Our actuators are equipped with two simple limit switch contacts normally set either in open position, either in closed position (see wir-
ing diagram DSBA0436). As per factory setting, the white cam is used to detect the open position (FC1) and the black cam is used to
detect the closed position (FC2).
The auxiliary limit switches must be connect with rigid wires. If the applied voltage is higher than 42V, the user must foresee a
fuse in the power supply line.
The voltages applied to each feedback switch (FC1 and FC2, SNAA690000 electronic board) must be exactly the same .The
reinforced insulation between the feedback signal and the motor control authorizes voltages up to 250V AC.
 Unscrew the right cable gland and insert the cable.
 Remove 25mm of the cable sheath and strip each wire by 8mm.
 Connect the wires to the terminal strip in accordance with the diagram p.15
 Tighten the cable gland (Ensure that it’s well mounted to guaranty the proofness).
Connection to feedback microswitches:
 4 to 24 V DC and 12 to 250 V AC
 minimum current 100 mA
 maximum current 5 A (resistive), 0.5 A (motor), 0.125 A (capacitive loads)
SETTING OF END LIMIT SWITCHES
The actuator is pre-set in our factory. Do not touch the two lower cams in order to avoid any malfunctioning or even damage to the
actuator.
 To adjust the position of the auxiliary contacts, make rotate the two superior cams by using the appropriate wrench.
 Re-mount the cover, fasten the four screws and attach the position indicator.

Wiring the electrical connector:
1. Remove the connector screw first, and then use a flat screwdriver to pry apart the two
connector halves. Note that the screw placed in the connector locks the two halves
together.
2. The center terminal is an optional ground that is normally used with AC current, and not
normally used with DC current.
3. When used with a solenoid valve, the polarity for the power con-nections is not
important. The two power wires can each be con-nected to either of the side terminals.
With electric motor actua-tors, the polarity should be observed for both AC and DC
opera-tion.
4. Place the connector on the electric motor actuator or solenoid valve coil and hold in
place with the supplied screw.
5. There are two different types of connectors that you may be using, ½” NPT Conduit and
Lead Wire. If you are using the Lead Wire type, a jacketed multi-conductor wire is
recommended. A rubber grommet is compressed around the jacketed conductor to
make a seal. If a tight seal is not important, then any type of wiring can be used.

** Possible defects : limitation of current, thermic limitation or program error
=> check that the valve torque is not superior to the maximum torque stand by the actuator
=> check that the actuator do not exceed the duty cycle indicated (possible overheat)
To re-start the actuator, reverse the sense of rotation or switch the power off and on.
