  1. If the measured voltage is less than specification, adjust the no. 1 Cable adjuster (4) as follows:
  1.  set the excva to the adjustment position. Refer to excv cable removal and installation .
Caution

adjusting the no. 1 Cable with the excv fully closed can damage the excva. Be sure to adjust the no. 1 Cable with the excv set in the adjustment position.

  1. Turn the no. 1 Cable adjuster (4) in or out to set the output voltage within the specified value.
Note

if c46 code is indicated after adjusting the voltage, increase the voltage to 0.9 V.
