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.
