Controller Manual: Gmr-32b Phase

Triggers when the physical phase sequence of R, S, and T lines is incorrectly ordered. If a reverse sequence is detected before or during system startup, the reverse phase lamp lights up, preventing motors from running backward and destroying internal mechanics. 4. Overvoltage Protection (Red Indicator)

Triggers automatically if the incoming source line climbs past the safely tolerated threshold. 5. Undervoltage Protection (Red Indicator) gmr-32b phase controller manual

Ensure the unit is positioned away from high-heat components like braking resistors or the SCR heatsinks themselves. Step 2: Signal Configuration (DIP Switch Settings) Triggers when the physical phase sequence of R,

380 VAC (operates up to 500V or 460V depending on the model variation). Step 2: Signal Configuration (DIP Switch Settings) 380

0-10V DC, 4-20mA, 0-5V DC, or Potentiometer (10k Ohm) Regulation Range: 0% to 99% of output voltage

Cause: The internal heatsink temperature has exceeded 85°C.
