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.
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 automa-
AS100/AS200/AS400
tically into declutched position.

WARNING
ASP/AS50/AS80 models:
Some of these actuators are equipped with declutchable intermediate
gears. 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 INTELLI, INTEGRAL, POSIGAM, 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 system (see wiring examples) in order to prevent potential
damage to the actuator or valve.
The following points must be checked:
a) Make sure that power supply voltage is in accordance with the data
engraved on the actuator nameplate,
b) Check that all cable glands are correctly tightened,
c) Move the valve manually to an half-open position,
d) Operate an electrical opening and check that the motor rotates
in the right direction. Press manually on the «OPEN» travel limit
switch ; the motor should stop.
In the same way, check that the closing electrical command as well
as the «CLOSED» travel limit switch are working correctly,
e) All models except OA : operate an electrical opening. Press manually
on the «OPEN» torque limit switch ; the motor should stop.
In the same way, operate an electrical closing check that
the «CLOSED» torque limit switch is working correctly,
If any misfunction was detected at this stage, please check the overall
wiring.
For safer working conditions, we recommend that the power supply now
be switched off especially if the actuator output max. torque exceeds
300 N.m.
