Installation & Operation Manual Proven Quality since 1892
ECON actuator Fig. 7907, type ELA80 – 3000 www.eriks.com
Rev.19 – April 2, 2021 21
I) Auto Full Action (A FULL)
Dip switch No. 3 (A_FULL) is in the ON position as shown above.
This setting will make the actuator run to the fully closed position if
the input signal is lower than 4.3mA. It will run to the fully open
position if the input signal is higher than 19.7MA
J) Reverse Mode
- When the Reverse Mode is set as shown on the picture on the
right, the actuator is responding in reverse to the input signal.
This means:
- When input (command) signal is 4mA, the actuator will run to the
fully open position and will send out 4mA as output signal
(feedback).
- When the input (command) signal is 20mA, the actuator will run
to the fully closed position and will send out 20mA as output
signal (feedback).
K) Setting the Optional Set Point
• ZERO (FULL CLOSE) Signal, SPAN (FULL OPEN) Signal for changing the Signal
• ZERO (FULL CLOSE) Signal SETTING Range: Generally 3 ~ 8 mA DC
• SPAN (FULL OPEN) Signal SETTING Range: Generally 16 ~ 21mA DC
Example
Please set full close (zero) to 5mA DC and set fully open (span) to 19mA DC
① Put dip switch No. 4 ON (SW3).
② RED & GREEN LED start blinking together.
③ After 1.5 Seconds, Only the GREEN LED blinks.
④ Put the 5mA input (command) signal on the input terminal, then push the black “
ZERO” button.
⑤ If the setting has succeeded, the YELLOW LED will blink once.
⑥ Check if the GREEN LED is on and the RED LED is blinking.
⑦ Put the 19mA input (command) signal on the input terminal, then push the white “
SPAN” button.
⑧ If the setting has succeeded, the YELLOW LED will blink once and the RED LED
is on.
⑨ Check if the RED and GREEN LEDS are blinking together and wait until only the
GREEN LED is blinking.
⑩ Put dip switch No. 4 back to OFF (SW3)
