INSTALLATION
4.1
Pre-installation
•
Please check if the electric power supply corresponds with your specification and the information on
the actuator type plate.
•
Make sure the power supply has been switched off before you start wiring the actuator.
4.1.1 Use in General Service
Verify the actuator
’
s nameplate to ensure that model number, torque output, operating speed, voltage
and enclosure type are correct before installation or use.
It is important to verify that the torque output of the actuator is appropriate for the torque requirements
of the valve and that the duty cycle of the actuator is appropriate for the intended application.
Make sure the power supply has been switched off before the actuator is being wired.
4.1.2 Use in Potentially Explosive Atmosphere
Model:
ELA80 ~ ELA3000
Type of Enclosure :
IECEx: Ex db IIB T4 Gb and Ex tb IIIC T135°C Db
ATEX: II 2 G Ex db IIB T4 Gb and II 2 D Ex tb IIIC T135°C Db
Ambient Temperature:
-20°C (-4°F) up to +60°C (140°F)
WARNING:
Read this installation, operation and maintenance manual carefully
and completely before attempting to install, operate, or troubleshoot
the ELA
actuator.
CAUTION:
Installation, commissioning, maintenance, repairs and modification work
may only be performed by qualified personnel with extensive knowledge on
how to work on explosion-proof electrical equipment.
4.2
Actuator Mounting
Note:
Prior to mounting, the part-turn actuator must be checked for any damage.
Damaged parts must be replaced by original spare parts
Mounting is most easily done with the valve shaft pointing vertically upwards. But mounting is also
possible in any other position.
The ELA-series electric actuators are supplied with a female double square drive output. The
ISO5211 bolt patterns are provided for actuator mounting. The actuator drive bush can be replaced or
removed for machining easily.
It is mandatory for the actuator to be firmly secured to a robust mounting bracket or to be mounted
directly to the valves
’
ISO mounting pad. High tensile bolts or studs with spring locking washers must be
used.
The valve stem must be in line with the actuator output drive to avoid side loads to the shaft. To avoid
backlash play between the actuator, mounting bracket and valve is not allowed.
CAUTION:
Do not attempt to work on your ECON actuator without first shutting off the power supply
Do not attach ropes or hooks to the hand wheel for lifting purposes
