1. SAFETY INFORMATION

This device complies to current applicable safety standards.
Installation, maintenance and use of this apparatus will have to be done by
skilled and trained staff only.
Please read carefully the whole document prior to mounting and starting-up.
WARNING
For explosionproof actuators, please also read carefully the special
instructions TMS1132 prior to mounting and starting-up

2. ASSEMBLY

Actuator should be secured directly to the valve using proper bolts or via a
proper interface.
After assembly, the actuator can operate in any position. However, cable
glands should not be oriented upwards (loss of water tightness) and the
motor will preferably not be positioned at the bottom (potential internal
condensation trap)
Note 1 : do not handle the actuator by handwheel, it could damage the
gearworm.
Note 2 : if the actuator was delivered mounted on the valve, the basic settings
should have been done. In this case, refer to § 3,4 and 9 only.
Note 3 : see §.9 for details on storage precaution prior to starting-up.
3. HANDWHEEL OPERATION AND DECLUTCHING
In general, the handwheel does not turn during electrical operation. Even if
turning, the solid handwheel does not have any protruding part and therefore
does not present any risk of any kind for the operator. Moreover, for the
actuators with the highest torque, the torque limit system brings an additional
level of protection.
OA models :
These actuators are equipped with a manually declutchable handwheel.
To operate manually the actuator, turn while pulling the handwheel in order to
mechanically engage it.
To declutch the handwheel, just push it back towards the actuator body.
AS100/AS200/AS400/SRA/SRC/ASM models :
These actuators are provided with an automatic declutching handwheel, with
motor drive priority. In order to operate manually the actuator, turn the arrow
of the handwheel clutch button in front of the triangular sign on the housing
(it might be necessary to turn the handwheel by a few degrees to release the
claws). When the motor starts, it returns automatically into declutched
position.
OAP/OA15/ASP/AS50/AS80 models :
Some of these actuators are equipped with declutchable intermediate gears.
AS100/AS200/AS400/SRA/SRC/ASM
By moving the clutch lever, the motor is physically disengaged from the
gears. Once the manual handwheel operation has been completed, do not
forget to clutch the motor back. Otherwise, once started-up, it would run and
heat up until the motor thermal protection switch closes. If repeated, these
conditions can generate a motor breakdown .

4. ELECTRICAL CONNECTIONS AND PRELIMINARY TESTS

If the actuator is equipped with INTEGRAL, MINIGRAL or MINIGAM
commands, please report to the specific documentation for wiring details.
Otherwise, all components of the actuator are wired to a common terminal
strip. Remove the cover and pass the cables through the cable glands (M20).
Refer to the wiring diagram for details on the terminals numbering system.
Both torque and travel limit switches must be integrated into your control
