Activate the pedal to the left,
measure the voltage is approx.
24VAC between pin 5 and 6 on
J5.
Still on Jumper J5, measure
voltage between pin 4 “analog
control” and 3 “GND”. By
activating the pedal, the voltage
varies from 0 to 5V. 5V at most.
If the voltage remains at 0V,
replace the generator.
If the 24VAC and analog control
are working correctly.
Measure the frequency between
pin 1 and 4 (still on J5); it can be
measured correctly with a
voltmeter with the option (Hz).
