Gmr-32b Phase - Controller Manual
Position the unit inside an enclosed electrical distribution box or power distribution cabinet away from direct water contact or corrosive environments.
Evaluates amplitude deviations. If line voltages breach pre-configured upper limits (surges) or lower limits (brownouts), the internal relay trips to safely isolate sensitive control logic.

Adjust the trimmer until the desired peak output voltage is achieved. 6. Diagnostic LEDs and Troubleshooting
380VAC nominal (compatible with 220V, 440V, and 460V industrial subsystems) Dual-rated for 50Hz and 60Hz power distribution grids Physical Dimensions 79 mm × 23 mm × 79 mm (3.11 in × 0.91 in × 3.11 in) Relay Contact Assembly
Slowly increase the control signal from your PLC or potentiometer and observe the load current to ensure smooth modulation. 7. Troubleshooting and Error Codes Two Normally Open (NO) + Two Normally Closed
⚡ High voltage equipment poses significant risks if handled improperly.
| Symptom | Probable Cause | Corrective Action | | :--- | :--- | :--- | | | No power supply / Internal Fuse blown. | Check L1/L2/L3 input connections; check internal fuse. | | Red LED Lit (Phase Loss) | Broken wire or blown upstream fuse. | Use multimeter to verify voltage on all three input terminals. | | Red LED Lit (Phase Seq) | L1, L2, L3 connected in wrong order. | Swap any two incoming power lines (e.g., swap L1 and L2) at the input terminal. | | Intermittent Tripping | Loose connection or Hysteresis set too low. | Tighten terminal screws; Increase Ud (Unbalance) threshold slightly. | | Relay Not Switching | External load exceeds relay rating. | Verify load current is < 3A; check for short circuit in external control wiring. |
