The exact you are controlling (e.g., resistive heaters, transformer, fan motor) The specific error code or symptom you are encountering Your current control input type (e.g., 4-20mA or 0-10V) : A concise summary of its electronic source
Connect the relay output (Terminals 4 and 5) to the coil of the motor contactor or the control circuit of a Variable Frequency Drive (VFD). Measure line-to-line voltage across terminals R-S, S-T, and
Measure line-to-line voltage across terminals R-S, S-T, and R-T using a multimeter rated for up to 600VAC. If 380V–460V is present but no LEDs light up, internal power supply components have failed.
