ELECTRICAL SHOCK HAZARD.To avoid serious personal injury,
property damage, turn off ALL power to the actuator before remov-
ing the cover.
Before installation or use, verify the nameplate information infor-
mation to insure the correct model number, torque, voltage and
enclosure type.
Be sure to completly review the actuator manual prior to operation.
Final limit switch adjustment MUST be done after mounting the ac-
tuator to the valve. Incorrect adjustment may cause actuator failure.
Over torque switches are factory set, tampering with the over
torque switch settings may damage the actuator and void the war-
ranty.
The actuator must be properly grounded. Use the grounding lugs
provided on the inside and outside of the actuator body.
To minimize the possible damage caused by condensation, be sure
to energize the heater.

This document describes the RCEL SA PCU, a top-quality valve actuator manufactured by Rotork Sweden AB. It provides comprehensive information on its function, technical specifications, usage, and maintenance.

Function Description

The RCEL SA PCU is an actuator designed for controlling valves, enabling precise and automated operation. It receives command signals (e.g., 4-20mA DC, 0-10VDC) and translates them into mechanical movement to open or close a valve. The device incorporates various features to ensure reliable and safe operation, including limit switches, over-torque protection, and diagnostic indicators. It can be operated in both manual and automatic modes, with an autoscan function for self-calibration and abnormality checks. The actuator is designed to prevent damage from hunting effects through a configurable dead band and incorporates a delay time to mitigate the impact of external noise or disturbances on the input signal.

Usage Features

Safety Precautions:

• Always turn off power before removing the cover to prevent electrical shock.
• Verify nameplate information (model number, torque, voltage, enclosure type) before installation.
• Review the manual thoroughly before operation.
• Ground the actuator properly using provided lugs.
• Energize the heater to minimize condensation damage.

Installation and Wiring:

• Final limit switch adjustment must be done after mounting to the valve.
• Over-torque switches are factory set; tampering voids the warranty.
• Use standard conduit and seal fittings to prevent moisture and humidity ingress.
• Seal unused conduit entries with provided pipe plugs.
• Each actuator requires individual relays to prevent voltage feedback.
• Group wires with ties and remove debris before replacing the cover.
• Main power should only be applied after the top cover is re-installed.

Setup and Order (Calibration):

1. Actuator Full Close: Manually close the actuator using the lever on the handle.
2. Close Limit Setting: Set the close limit switch.
3. Potentiometer Check: Determine the potentiometer value when the actuator is fully closed (factory set to 80-1200). Reset if outside this range.
4. Actuator Full Open & Open Limit Setting: Manually open the actuator and set the open limit switch.
5. Electric Wiring and Power Input: Confirm wiring diagram and nameplate match. Ensure correct input/output polarity if the substrate has changed.
6. Auto Scan: Press the autoscan button for at least 2 seconds for proportional control. The actuator will automatically close and open to check for abnormalities.
7. 4-20mA Input: After entering the 4-20mA input, verify normal operation.
8. 4-20mA Output: Adjust the output volume using switches if it doesn't fit.

Limit Switch Setting:

• Rotate the actuator manually to the desired position (closed/open).
• Loosen the cam set screw and rotate the cam to actuate the limit switch.
• Firmly tighten the cam set screws.

Potentiometer Setting:

• Set the resistance value with the actuator power OFF to ensure accuracy.
• Fix the mudu bolt after setting to prevent gear movement.

Indicator Setting:

• The visual DOME indicator shows valve position.
• LEDs provide visual confirmation (Power, Fault, Open, Close).
• If the indicator is misaligned, loosen the bolt, manually turn the indicator to the correct position, and re-tighten.

• ZERO/SPAN/ASCN: Buttons for manual control (close/open) and autoscan.
• DEAD BAND/TIME DELAY: Mechanical steps (0.2mA) and modulating starting time (1sec).
• DIP SWITCH (K55625):
  • F-O (Fail Open), F-C (Fail Close), A FULL (Full Close/Open input ranges), CH1/CH2 (Discretion/Manual Setting), REV (Reverse Action).
• INPUT SIGNAL SELECTION (KSS03S): Configures the actuator for 4-20mA, 2-10V, 0-5V, 0-10V, or 1-5V input signals using ON/OFF switch combinations.

Other Settings:

• Input Error (Full Open/Close): DIP Switch No.1/No.2 ON for automatic full open/close on error.
• Actuator Reverse Setting: DIP Switch No.6 ON for reverse action.
• A FULL Function: DIP Switch No.3 ON for full close/open at specific mA ranges.
• Input Signal Change: DIP Switch KSS03S for changing input signal types.

Maintenance Features

Recommended Cycling:

• Cycle the actuator every two weeks after purchase.

Condensation Prevention:

• Seal cable entries and energize the heater to minimize condensation.

Troubleshooting Guide:

• Manual override not functioning: Gear failure (disassemble and replace gear).
• Motor does not operate:
  • Main power failure (check main power).
  • Motor/Condenser damage (replace motor/condenser).
  • Motor overheated/thermal protector disengaged (check frequency of operation or jammed gears).
  • Wiring failure (confirm proper wiring).
