SIPOS 5/7 Series Electric Actuators: ECOTRON & PROFITRON Wiring and Commissioning

SIPOS electric actuators come in two classes: ECOTRON (economy, contactor-controlled, fixed speed) and PROFITRON (professional, VFD-controlled, variable speed with torque curves). The SIPOS 7 series is the successor to series 5, sharing the same architecture and operating philosophy. This article covers terminal wiring for both classes, commissioning procedures and common fault remedies. Reference: SIPOS 5 Flash ECOTRON/PROFITRON Chinese manuals (E20185-P920-B701-X-5D00), PROFITRON wiring diagram (Y070.061/CN), SIPOS SEVEN manuals (Y070.301/ZH, Y070.302/ZH).

ECOTRON (Economy) Terminal Wiring

Terminal	Function	Description
U1、V1、W1、PE	Three-phase supply + earth	380V three-phase input (phase order irrelevant)
X3.1-3、X3.1-6	Stop command	Valve stop signal
X3.1-3、X3.1-4	Close command	Remote close signal
X3.1-3、X3.1-5	Open command	Remote open signal
X3.2-1、X3.2-2	Fully-open feedback	Open feedback signal
X3.2-5、X3.2-6	Fully-closed feedback	Closed feedback signal
X3.2-11、X3.2-12	Fault signal	Fault feedback signal

Wiring note: terminals 18 and 19 must be jumpered.

PROFITRON (Professional) Terminal Wiring (with relay board)

Terminal	Function	Description
U1、V1、W1、PE	Three-phase supply + earth	380V three-phase input (phase order irrelevant)
X3.2-14(+)	Command input +	Control command positive
X3.2-15(-)	Command input -	Control command negative
X3.1-1、X3.1-2	Position feedback	4–20 mA position feedback (+/-)
X3.2-13、X3.2-14	Remote control	Remote signal

Wiring note: position feedback needs no DCS card power supply.

ECOTRON vs PROFITRON

• Economy: contactor control, fixed speed. Professional: VFD control, adjustable speed
• Economy: mechanical torque switch. Professional: electronic torque detection with torque curves
• Economy: commissioned with buttons and potentiometers. Professional: menu-driven

ECOTRON (SIPOS 5) Commissioning

Step 1: Preparation

• Switch the actuator to local and open the control-unit cover and signal-gear-unit cover

Step 2: Start commissioning

• Set S8 to ON to begin; turn the signal gear to the commissioning position

Step 3: Open the valve and set the open limit

• Press the open button (or handwheel to fully open) and observe the rotation direction of the white signal gear (centre wheel E)
• Turn the gear carefully in the direction it rotated while opening until the H2 red lamp goes out; set S7 to ON then OFF — the open position is set

Step 4: Set the close limit

• Press the close button (or handwheel to fully closed) and observe the white signal gear rotation angle (normal: more than 90°, less than 270°); set S7 to ON then OFF — the close position is set

Step 5: Finish

• Set S8 to OFF; when confirmed the H1 green lamp stays lit

PROFITRON (SIPOS 5) Commissioning

Switch to local

• Press the LOCAL/REMOTE button on the control panel to switch to LOCAL

Enter the commissioning menu and password

• Press ENTER to enter the "Sprache lang." language menu
• Press ↓ until "COMMISSIONING" appears; press ENTER to enter the commissioning menu
• The display shows "0000"; the password is "9044": cursor on digit 1 — press ↓ for "9", confirm; digit 2 — confirm; digit 3 — press ↑ for "4", confirm; digit 4 — press ↑ for "4", confirm

Set the open limit

• Press ↓ until "endpost. adjust" appears; "start with pos. open" — press ENTER
• "move to op.pos" / "press E-button": press open to run the valve toward open, watching the white gear direction; stop at fully open
• After 2 s press ENTER; a number appears — turn it to zero following the gear rotation direction and press ENTER

Set the close limit

• "move to cl.pos": press ↓ to close, stop at fully closed and observe the white gear angle (proper range 120°–300°); press ENTER — "adjustment OK!" appears

Finish

• Press local/remote; the display first line shows "remote"

Common Faults and Remedies

Fault code/symptom	Meaning	Remedy
ESD alarm	Emergency shutdown triggered	Check ESD source, clear the fault, reset
Phase-loss alarm	Three-phase supply loss	Check supply lines and fuses
Torque exceeded	Valve sticking or packing too tight	Check valve mechanically; adjust torque setting
Travel exceeded	End positions wrongly set	Readjust end positions
VFD fault	Overcurrent/overvoltage/overheat (professional)	Check load; improve cooling; replace VFD if necessary

SIPOS 7 Series Note

SIPOS 7 (SEVEN ECOTRON/PROFITRON) inherits the series 5 VFD architecture and commissioning philosophy, upgrading the HMI, diagnostics and fieldbus communication — adding a Web server, richer condition monitoring and predictive maintenance. Terminal wiring is essentially identical to series 5; commissioning uses a graphical interface.
