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 sys-
tem brings an additional level of protection.
SQ4 to SQ15:
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.
SQ100, SQ250 - SQ1000 :
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 automati-
cally into declutched position.
