4 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

actuator.
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 t o be mou n t ed
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 li fti ng purposes

4.4 Torque Switch Setting
The torque spring, which detects the variation of torque during the operation, is installed to prevent
damaging the valve and actuator under overload conditions. If an overload of the actuator occurs, the
torque switch will be activated and the actuator stops immediately.
The torque switches are set by manufacturer on the production site. If re-setting is necessary, please
contact the ECON actuator distributer before setting the torque switch.
CAUTION:
Do not reset t h e torque switch to a setting higher than the maximum setting
stated by the manufacturer.
4.5 Counter-Clockwise to Close Setting
Standard actuators are normally set to clockwise rotation to close. However, the rotation can be
reversed to counter-clockwise to close by simply reconfiguring the wiring as follows:
Reverse wiring on the main terminal block: 9 & 10 as well as 11 & 12.
Adjust the visual indicator to suit the counter-clockwise rotation.

Loosen both (open and close) travel stopper bolt nuts.
Operate the actuator manually by turning the hand wheel (the clutch lever must be
switched to “manual” first) to the closed position until the “close” open limit switch is being
activated.
Tighten the close travel stopper bolt until resistance is felt. (In this position the close travel
stopper bolt should not be able to travel any further).
Loosen back the close travel stopper bolt by only one turn and tighten the close travel stopper
bolt nut.
Repeat the same operation for setting of the open travel stopper bolt.

4.7 Setting Potentiometer (Optional)
The potentiometer has been calibrated at the factory. However, if re-calibration is required, proceed as
follows:
Manually rotate the hand wheel of the actuator to the fully closed position.
While measuring the resistance between P1 (black) and P2 (blue), gently rotate the
Potentiometer Gear until it reaches between 80 - 120 Ω (100 Ω preferred), by using a flat head
screw driver.
Engage the Potentiometer Gear into the Point Shaft Gear and use an Allen key to fasten the
locking bolt of the Potentiometer Gear.

4.8.2 Calibration of Zero and Span - CPT
The settings of Zero and Span have been calibrated at the factory. However, if re-calibration is required,
proceed as follows:
Apply power (or use the manual override) to move the actuator to its fully closed position
(clockwise rotation).
When the actuator is in the fully closed position, adjust the ZERO close setting on the CPT board
until an output value of 4mA is achieved.
Apply power (or use the manual override) to move the actuator to its fully open position
(counter- clockwise rotation).
When the actuator is in the fully open position, adjust the SPAN open setting on the CPT board until
an output value of 20mA is achieved.
