On the measure card there are n°2 trimmer P18 corresponding to VG1 voltage presence and
P19 for VA voltage presence. These two trimmers set the thresholds for the VG1 and IA
voltage presence on the equipment. Once that is been verified the voltages presence, the
relays are closed to enable the protection box and leds D17 and D19 are light on to signal
the controlled voltage presence.
In case that on the equipment is installed a triode tube, the checking of the VG1 is excluded
because this voltage is created automatically when the tube is in power and is created
inserting the jumper JP14 to have a short circuit so that the starting sequence is ok,
otherwise the equipment never go in high tension.
