Understanding the core threshold limits of the GMR-32B ensures safe integration into your control circuit. Specification Details 300V to 400V AC, 50/60 Hz Output Configuration Single-Pole Double-Throw (SPDT) Relay Contact Rated Contact Load 5 A at 250 VAC / 30 VDC (Resistive Load) Inductive Contact Load 1 A at 250 VAC / 0.2 A at 48 VDC Phase Loss Response Time ≤ 0.1 seconds Phase Sequence Response 0.1 s ± 0.05 s Mechanical Service Life Minimum 10,000,000 operations Mounting Format Standard 35 mm DIN Rail Ambient Operating Temp -20°C to +60°C (No condensation/icing) 2. Core Protection Functions Explained

Locate the DIP switches or internal jumper block on the control board (accessible by removing the plastic faceplate cover). Toggle the switch corresponding to your input type: Configures the unit for 4-20mA operation. Switch 2 ON: Configures the unit for 0-10V DC operation. gmr32b phase controller manual

: If 380VAC is verified at the inputs but no diagnostic LEDs or contact relays actuate, the unit's internal power supply may be blown due to an unsuppressed voltage surge. Replace the module.

Note: Some GMR32B revisions have digitally stored calibration. In that case, use the “AUTO-TUNE” button (press 3 seconds) during step 4. Are you facing a specific right now

Protect the controller against short circuits by installing fast-acting semiconductor fuses (I²t fuses) on the main line input. Standard circuit breakers do not trip fast enough to protect internal thyristors. Physical Mounting Identify a cool, dry section of your electrical enclosure.
