ABB G3FD HENF452692R1 Matrix switch module

Rotate the current knob clockwise. D) Rotate the voltage knob completely clockwise. The front panel's voltmeter should display the maximum output voltage of the supply. The voltage indicator should glow. E) Rotate the current knob completely counter clockwise; the output voltage should drop to zero. F) Rotate the current knob clockwise. The output voltage should rise to its original value. Rotate the OVP potentiometer counter clockwise. The output voltage should drop to zero volts. G) Since the OVP circuitry latches on itself, rotate the OVP potentiometer completely clockwise. Flip the circuit breaker OFF and then ON to disable the OVP. The voltmeter should display the output voltage.

Rotate the voltage knob completely counter clockwise

monitor the front panel voltmeter. The output voltage should gradually decrease to zero. Flip OFF the circuit breaker of the supply. I) Apply a short wire, that can sustain the maximum output current, across the output terminals of the supply. J) Flip ON the circuit breaker of the supply. Rotate the voltage knob clockwise. Rotate the current knob completely clockwise. The front panel ammeter should display the maximum output current of the supply. The current indicator should glow. K) Rotate Current knob completely counter clockwise. The output current should drop to zero. Flip OFF circuit breaker. If any inconsistency from the above test procedure is noted, please do not hesitate to call Lambda-EMI for assistance.
