A detailed wiring diagram specific to your control circuit should always be referred to from an official manufacturer's manual, as available from your supplier.
The model number "GMR-32B" strongly resembles the nomenclature used by Gecom (Global Energy Control) for their Generator Controller/Auto Mains Failure (AMF) Controllers (specifically the GMR series). It is likely a typographical variation of the GMR-31B or GMR-32 series.
Disclaimer: Always follow the specific, physical manual provided by the manufacturer of your GMR-32B device. This article is a general guide based on common GMR-32B specifications. gmr-32b phase controller manual
The device features a (or "reset") function. For example, if the unit trips on undervoltage at 340V, it will only automatically reset once the voltage recovers to a higher level (e.g., 345V). This prevents rapid relay oscillation when voltage is borderline, extending contactor and device life.
0-10V DC, 4-20mA, 0-5V DC, or Potentiometer (10k Ohm) Regulation Range: 0% to 99% of output voltage A detailed wiring diagram specific to your control
Wire the relay's control output to the contactor coil or motor starter circuit.
A red light or a dark indicator indicates a fault. For example, if the unit trips on undervoltage
Integrated into the starter's control circuit (e.g., stop/start push buttons) so that any fault condition immediately trips the contactor and stops the motor.
Triggers when a system sag drops lower than the specified minimal operating pressure, keeping industrial equipment safe from high-amperage draws associated with low-voltage drops. 🔌 Hardware Installation & Main Circuit Wiring Critical Sampling Rule
: Align the rear locking bracket with a standard 35mm HT35 DIN rail. Press the device down firmly until the internal spring mechanism clicks into place.
