This is an operation, installation and maintenance manual of the EX200 electro-hydraulic actuator positioner produced by Bifold Orange Limited
The EX200 electro‑hydraulic actuator positioner is a compact DIN‑rail mounted device that controls hydraulic actuators via 4‑20 mA command signals. It offers manual, stepping and HART communication modes, optional AC power, and can be housed in standard or Ex‑d enclosures for hazardous areas.
The manual covers physical installation, wiring guidelines, jumper‑link configuration for solenoid sense, fault handling, pump control options, stepping timer setup, and detailed calibration procedures. Safety notes and fault‑detection behavior are also described to ensure reliable operation in process control systems.
| Command signal range | 4‑20 mA |
|---|---|
| Actual position output | 4‑20 mA calibrated |
| Power consumption (normal operation) | < 1.5 W |
| Auxiliary solenoid output | 24 V DC open‑drain |
| Fault output | 24 V DC open‑drain |
| Enclosure dimensions (DIN‑rail version) | 85 × 70 × 58 mm (H) |
| Optional AC supply voltage | 115‑230 V AC, 50/60 Hz |
Select the appropriate jumper links (LDEC +/- or LINC +/-) on the PCB to define which solenoid is energized at the balance point.
