Description

Woodward 3522-1004 Digital Control Module Operation Guide

‌Core Functions‌

‌Speed/Droop Control‌: Regulates prime mover (diesel/gas engines) speed stability (±0.25% steady-state accuracy).
‌Load Sharing‌: Syncs parallel gensets via 3%–5% droop compensation (ISO 8528 compliance).
‌Analog I/O‌: Processes 4–20mA/0–10V signals for critical parameters (e.g., temp, pressure).

️ ‌Safety Precautions‌

‌Electrical Safety‌
- De-energize all inputs/outputs before wiring (380V max rating).
- Ground chassis to facility earth bus (resistance ≤0.1Ω).
‌Environmental Limits‌
- ‌Operating Temp‌: -40°C to +85°C (derate above 70°C).
- ‌Humidity‌: 5%–95% non-condensing.

🔧 ‌Hardware Installation‌

textCopy Code

1. Mount module on DIN rail (EN 60715 compliant).

2. Connect power: Terminals 1(+) / 2(-) | Range: 18–36VDC.

3. Wire actuator:

   - SPDT output: Terminals 5 (COM), 6 (NC), 7 (NO) | Max 5A @ 30VDC.

4. Link sensors:

   - Magnetic pickup (MPU): Terminals 12/13 | 80–250 Vac RMS.

   - RTD/thermocouple: Terminals 14–17 (Shield to FG).

‌Initial Configuration‌

Using Woodward ToolKit™ Software (V4.0+):

Establish RS-485/Modbus connection (baud: 19200, parity: even).
Set operating mode:
- Mode 0: Isochronous (standalone)
- Mode 1: Droop (grid-parallel)
- Mode 2: Base load
Calibration sequence:
textCopy Code

a. Zero adjustment: Disconnect actuator → Execute [CAL_ZERO]. b. Gain adjustment: Apply 75% load → Tune [GAIN] until freq. = 60.0±0.1Hz.

‌Fault Diagnostics‌

‌LED Code‌	‌Fault‌	‌Corrective Action‌
‌Red Flashing (1Hz)‌	MPU signal loss	Verify sensor gap (1.0±0.2mm) / shielding
‌Red Solid‌	Over-temperature	Check ambient cooling / derate load
‌Amber Flashing‌	Actuator saturation	Recalibrate stroke limits

🔄 ‌Maintenance Schedule‌

‌Interval‌	‌Task‌
‌Quarterly‌	Clean ventilation slots (IPA wipe)
‌Biannually‌	Verify calibration drift (<±0.5%)
‌Annually‌	Replace backup battery (P/N: 8276-655)

‌WARNING‌: Unauthorized potentiometer adjustments void UL/CE certification.
