2. Product Overview
ECON Fig. 7917EX ELSA series explosion-proof spring return fail-safe actuators are
designed and manufactured as flame-proof and combustible dust-proof products.
ECON ELSA series spring return fail-safe electric actuators offer torque ranges from 50 Nm
up to 260 Nm (445 in-lb to 2300 in-lb) and are designed for fail-safe positioning of quarter-
turn valves or dampers upon loss of supply voltage, which include On/Off control, floating
control and modulating control. A rack and pinion spring mechanism is used to position the
controlled device to either fully OPEN or fully CLOSED position without any external power
source. For On/Off types, a mechanical BUFFER is used at the end of the spring stroke to
reduce the “water hammer” effects in pipes. A clutch-less manual override is provided for
manual positioning of the controlled device. Actuators without a manual override can be
ordered as an option.

3.5 Sizing
For safety reasons, do not remove or inspect the SPRING STRUCTURE. Proper
tools must be used or serious injury will occur
The actuator shall be sized to ensure that its torque output meets the operating torque of the
valve and its ability to overcome the required duty cycle of the application (A safety factor of
minimal 30% on top of the required valve torque is recommended).
If the maximum torque of a valve is 80 Nm  80 x 1.3 = 104 Nm
104 Nm < 130 Nm (ELSA130)  OK!
104 Nm > 50 Nm (ELSA50)  NOT OK!
3.6 Duty Cycle – IEC
 The duty cycle is the relationship between the running time and resting time. It is
calculated as below:
Duty Cycle = x 100 %
Rest Time (s) =
 If the motor running time is 10 s, the spring return time is 5 s and the duty
cycle is 50%, the rest (off) time shall be calculated as below:
 Running time: [ 10 s × ( 1 - 50 % ) ] / 50 % = 10, rest time is 10 s
 Reset time：[ 5 s. × ( 1 - 50 % ) ] / 50 % = 5, rest time is 5 s
One cycle is equal to: open-rest-close-rest
A rest time is required after spring return action because the gear train
and motor are driven during spring release.
3.7 Flame path Joint
The following conditions apply to both certificate numbers SIRA 19 ATEX 1176 X and
IECEx SIR 19.0043X: The flame paths in this equipment are different to the standard
dimensions given in EN/IEC 60079-1. If specific flame path dimensions are required
then the manufacturer (OEM) must be contacted.

4.3 Wiring Instructions
Turn off the power before making the electrical connection!
 There are grounding devices both inside and outside of the actuator (green screws).
The grounding wires should be connected properly.
 Both conduit entries are plugged with metal plugs according to the specification as
mentioned below.
ELSA50 to ELSA260: 1/2” NPT, 3/4” NPT, M20 x 1.5 or M25 x 1.5.
Use correct glands with threaded ends that match the inside threads of the
actuator in order to prevent dame to these threads.
 Verify the supply power is in accordance with the data on the nameplate to prevent
a short circuit and an electrical shock.
Do not apply power to the actuator before wiring, otherwise it can cause an
electrical shock or damage the components of the actuator.
 After wiring, please tighten the conduit entries with suitable cable glands and cover
properly. Unused conduit entries have to be sealed with metal plugs to reach the
explosion-proof function. Please refer to section 1.2.2.
4.4 Actuator Set-up
If the actuator is equipped with a manual override, rotate the handwheel to return
the actuator to its fully unloaded spring position before the power is supplied.
Securely tighten the conduit fittings to ensure the enclosure protection rating.
The spring return actuator provides fail-safe positioning and the end stop position of the
spring return action is determined by either a buffer or mechanical stop (On/Off by the buffer,
floating or modulating limited by mechanical stop). When the actuator is motorized, the end
position is determined by limit switches.
The actuator has been set and calibrated at the factory. Most products will not require
recalibration of these settings. However these are general settings. After the valve and
actuator are bolted together, apply power to drive the actuator to its fully-open (spring
compressed for a spring to close actuator). Then remove power to let the rack and pinion
spring mechanism drive back to its fully-closed position. If the OPEN or CLOSE stop point
are not aligned with the valve or damper position correctly, the end positions must be
adjusted. Please follow steps below:

b. Turn the power off and let the spring unit drive the actuator back to its fully-open
(spring released) position.
c. If it is required to adjust, loosen the cap bolt of cam TC1 with a 2.5m hex key.
 To increase the opening angle, turn the cam clockwise.
 To decrease the opening angle, turn the cam counter-clockwise.
【ELSA50】 ELSA130 up to ELSA260】
d. After adjusting the cam, apply power to drive the actuator to the fully-closed position.
e. Verify that it is in the correct fully-closed position.
 If it is in correct position, turn the power supply off and lock the cap bolt of cam
TC1.
 If it is not in the correct position, repeat step C until the correct position is reached.
f. If auxiliary switches will be used for feedback, cams TC3 and TC4 need to be
calibrated.
 Adjust cam TC3 so it trips just before cam TC1 does
 Adjust cam TC4 so it trips just before cam TC2 does.
For modulating actuators, after completing the calibration, turn the actuator to the
fully-closed position and follow the procedure below:
a. Loosen M5 set screw.
b. Rotate the sector gear clockwise
to the position shown in the
figure below.
Ensure that the round gear and
sector gear are engaged
properly.
c. Tighten M5 set screw.

5. Modulating Control Board Adjustment
5.1 Modulating Control Board Surface
The layout is based on 115 / 230V voltage.
TC2 is utilized for sensing fully-closed stop point. Once the spring mechanism has been
released when power outage, the actuator will not drive under power again until it has reached
its fail stop position and TC2 trips.
TC1 ”OPEN ”
Clockwise: increase opening degree.
Counter-clockwise: decrease opening degree.
Note:
LS2 shall trip while TC2 reaches the end stop point.
TC3 & TC4 are optional, refer to section 4.4.1 and 4.4.2 for calibration.

5.3 Dip Switch Setting (SW1)
The Dip Switch SW1 is a combination of 8 switches and equally divided in two rows. It is
utilized to select the input signal type as well as the output and fail
positioning type,when the signal input fails. The sliders can be
placed at either ON (upper) or OFF (lower) state position. Factory
settings are switches 1, 4, 8 at ON state and switches 2, 3, 5, 6, 7
at OFF state.
Please follow the steps below if an adjustment of these settings are required. Please
restart the actuator after adjusting.
