Shielding:

When using long communication cables (up to 15m for RS-232C), always connect the shield line to the FG (frame ground) terminal to minimize signal noise.

• 4-digit LED display (PV – green, SV – red)
• Keys: SET, ▼, ▲, R/S (run/stop)
• Modes: PV/SV display, parameter setting, tuning

• No display: verify power supply voltage and fuses; check wiring and terminal screws.
• Incorrect temperature reading: confirm sensor type selection, check sensor wiring polarity and connection, and test sensor with a handheld thermometer or multimeter.
• Output not switching: verify output configuration (relay vs SSR), check the controller’s status LEDs, confirm load wiring, and test output with multimeter.
• Excessive overshoot/oscillation: run autotune again or reduce P/increase D; ensure correct output type (SSR vs relay) and consider adding mechanical or electrical filtering.
• Intermittent errors: check for loose terminals, electrical noise (use shielded cable for sensors), and grounding issues.

Control Methods:

Options include standard PID control, ON/OFF control, and advanced "RationaLOOP PID (Ra-PID)" combined with self-tuning for minimized overshoot. yamatake sdc20 user manual
