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
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

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.

Note 2: If the ELA150~3000, 115/230VAC actuators only will be operated by open and close
commands on terminal 11 and 12, the following procedure must be followed in order to select
the desired feedback signal:
• Select the output signal by adjusting the DIP switches as mentioned in this paragraph.
• Connect the power supply; Neutral on terminal 5 and Live on terminal 13.
• Make a link between terminal 13 and 14 and connect a multi-meter to terminal 17 and 18.
• Push “auto adjust” (red button on the circuit board) for 2 seconds.
• The actuator will now “auto adjust” itself.
• After the adjusting cycle has stopped, remove the link between 13 and 14.
• Now the actuator van be operated by giving the open and close commands on terminal 11
and 12. The feedback signal will be given on terminal 17 and 18.
• The feedback signal however still needs to be checked and if necessary adjusted. Therefor
measure the voltage or current on terminal 17 and 18, while opening and closing the
actuator. If necessary adjust the potentiometers “zero” and “span” on the bottom of the
circuit board until the output values are correct.

Rev.13 - January 7, 2019 21
perform the Auto Setting motion:
1) The blue LED starts flickering
2) The red LED starts flickering for 5 seconds
indicating that the actuator is moving to the
open position
3) Pause for 2 seconds
4) The green LED starts flickering, indicating
that the actuator is moving to the fully
closed position
5) Pause (the green LED on) for 3 seconds
6) The red LED starts flickering, indicating that
the actuator is moving to the fully open
position
7) Pause (the red LED on) for 3 seconds
8) Moving back to the command position
Note:
Since the actuator is already set at the factory, no further settings are required
unless the user has made adjustments to the Limit Switch or the Potentiometer
settings.
F) Manual Operation
This function allows the user to manually operate the
actuator.
To access this function, press the ZERO (black)
and SPAN (white) buttons simultaneously for 2
seconds and the yellow LED will be lit to indicate that
the actuator is in Manual Operation mode.
Pressing the ZERO button will move the actuator
to the close position and pressing the SPAN button
will move the actuator to the open position.
If no operation occurs within 5 seconds, the PCU
automatically terminates the Manual Operation mode
or alternatively press the ZERO and SPAN buttons
simultaneously for 2 seconds. In both cases, the
yellow LED will be lit off to indicate the termination of
the Manual Operation Mode.
Note: During the Manual Operation mode, the input signal is ignored.

G) Customizing Set-points (CH 1 Switch)
This function is used when the user wants to set
different set-points for fully open and fully closed
positions.
For example, if the user wants to assign 5mA as
the set-point for the fully closed position, first of all
switch- on (move up) the CH1 switch (switch 4).
Supply a 5mA signal and push the ZERO button
once. Hereafter, the actuator will acknowledge the
5mA signal as the set-point for the fully closed
position and transmits a 4mA feedback signal.
Similarly, for setting the set-point for the fully open
position, supply the desired signal (for example,
19mA) and push the SPAN button once. Switchoff (move down) the CH1 switch to complete the
setting. After this action, the actuator will operate
according this new setting.
H) Reversal Acting (CH 2 Switch)
This function allows the user to reverse the input
and output signals for the operation of the actuator.
For standard operation (CH 2 switch down), the
input signal of 4mA operates the actuator to the fully
closed position and the actuator transmits the output
signal of 4mA. However, if the CH 2 switch is on (
up) the input signal of 4mA operates the actuator to
the fully open position and still transmits a 4mA
output signal.
Manually move the actuator to the half-open
position and push the ASCAN button once to
execute the Auto Setting (see 4.10.2 E). Supply
signal and check the operation.
I) Deadtime
The actuator will only start to move if the change of
the input signal value is greater than the deadband
set value (see 4.10.2 J) and when the signal value
is maintained for the duration of the deadtime time.
This prevents malfunction of the actuator caused
by unwanted signals in the input signal such as
noise and interferences.
Turning the Delay Time Dial in clockwise
direction will increase the deadtime time (Range
0.05 to 7.5 seconds).

5.1 ProfiBus Contoller
The ProfiBus Controller is providing multiple communication
functions by using a 8 bit microprocessor and ProfiBus controller.
Providing the operator with actuator status information in order to
confirm if the ProfiBus device and actuator is working
correctly
The maximum transmission speed is 12Mbit/s.
Easily can be switched between PCU-version and ON-
OFF-version.
Providing System Redundancy by using dual ports and
high reliability.
LED lamps indicate the actuator status.
5.1.1 Specification
5.2 ModBus Controller
This clause explains the ModBus-RTU Slave
Module (MBRSM). Positioned at level 7 of the
OSI model, ModBus is an application layer
messaging protocol that provides client/server
communication between devices connected on
different types of buses or networks.
As a ModBus Serial Line protocol, ModBus-RTU
(Remote Terminal Unit) is a Master-Slave
protocol which takes place at level 2 (Data Link
layer) of the OSI model. The master initiates the
communication by transmitting the Function Code
(a ‘request’) to the address of a slave and after
receiving and processing the Function Code, the slave returns a message (a ‘response’).
The slaves shall not communicate with each other without the request of the master. Since the

Installation & Operation Manual Proven Quality since 1892
MBRSM is based on the 2 wire (half-duplex) RS-485 communication, the network length limit or
the number of station should follow the standards of the RS-485 communication. To extend the
network, such as adding another segment, repeaters can be used. To ensure stability of the
network system, the network redundancy can be configured to slave redundancy.
ModBus manages the access of data simply and flexibly. ModBus supports two data types: A
Boolean value and an unsigned 16-bit integer. Generally, it is common for field devices to have
certain values defined as inputs while other values are outputs, such as current temperature or
valve position.
5.2.1 Specification
Communication Protocol: ModBus-RTU according to IEC 61158 and IEC 61784
Topology: Line topology with termination
Number of nodes: 32 nodes in each segment without repeater, with repeaters expandable to 247
Number of repeaters: Max. 9 with signal refreshing
Cable length: Max. 1.2 Km with Repeater 10 Km
Transfer Mode: RS-485

6.1 Electrical Connections and Preliminary Test
WARNING:
If working in potentially explosive areas, observe the European
Standards EN 60079-14 “Electrical Installation in Hazardous Areas” and
EN 60079-17 “Inspection and Maintenance of Electrical Installations in
Hazardous Areas”. Work on the electrical system or equipment must
only be carried out by a skilled electrician himself or by specially
instructed personnel under the control and supervision of such an
electrician and in accordance with the applicable electrical engineering
rules.
For cable gland or conduit entries that are not used, user or installer
shall close those entries by certified blanking elements in order to
maintain the enclosure protection. Extra attention is required for
selecting the correct “Ex db IIC” or “Ex tb IIC” blanking elements.
For cleaning a dust ignition proof closure, a damp cloth shall be used.
An explosion proof enclosure must be treated with care. Seals and
sealing surfaces may not be damaged in any way. Do not jam during
assembly.
Dust ignition proof enclosures may not be charged with an electrostatic
load. It therefor shall be installed in such a way, that the risk from
electrostatic discharge and propagation brush discharge, caused by
rapid flow of dust, is avoided.
For testing purposes, loosen the bolts of the actuator cover and remove the cover.
Make sure that the power supply voltage is in accordance with the information on the
nameplate of the actuator.
Cables shall be passed through the cable glands: M25 or NPT ¾” for “Ex db” versions. M25, M20
and NPT ¾” with M30 adapter shall only be applied for “Ex tb” versions.
Connect wires according to the enclosed wiring diagram (See Appendix I)
Manually move the valve to the half-open position. Then electrically operate the actuator to
the fully open position and check if the motor rotates in the correct direction. According to the
applicable standards, the actuator must be closing in counter-clockwise direction.
Test the actuator and check whether the limit switches work correctly
After testing, check if all cable glands are correctly tightened. Applicable cable glands must be
selected to meet the application’s condition. It is recommended to use at least IP67 cable glands.
Put the cover back on the actuator and tighten the bolts.
DANGER:
HAZARDOUS VOLTAGE. Electrical power must not be connected
until all wiring and limit switch adjustments have been
completed. Once the power is supplied to the actuator,
precautions must be taken if the cover is not mounted.
