Yamatake Sdc20 User Manual

For transmitting signals, the 4-20mA or 1-5V signals are mapped to corresponding terminals. Output Wiring

The SDC20 features an automated calibration loop system to optimize Proportional (P), Integral (I), and Derivative (D) matrix factors. How to Run Auto-Tuning

Moves the cursor digit-by-digit during numerical edits to accelerate entry.

Verify your specific model's voltage rating (e.g., 100-240 Vac) before powering on the unit. Sensor Input Connections yamatake sdc20 user manual

Check terminal connections 13 and 14. Replace broken thermocouple or RTD element. Internal hardware memory corruption (EEPROM error).

Confirm terminal screw tightness during annual maintenance shutdowns, as thermal cycling over time can cause wires to slowly loosen. For transmitting signals, the 4-20mA or 1-5V signals

The display flashes during adjustment. Press or wait 5 seconds to lock in the value. Step 3: Enabling Auto-Tuning ( At )

Run/Ready status. In Ready mode, control output is turned off. Parameter Bank ( PArA )

When an internal fault or unusual process event occurs, the SDC20 displays specific diagnostic error codes on the upper PV display screen. Error Code Corrective Action Internal hardware failure. Cycle input power. Replace unit if error persists. E02 EEPROM Error Corrupted configuration memory. Perform a factory reset and re-enter parameters. AL01 PV Upscale Burnout Sensor broken or disconnected. Verify your specific model's voltage rating (e

Options include relay, voltage pulse (for SSR drive), or current (4-20mA). Indication Accuracy: ±0.5% of full-scale reading.
