5-2. Adjustment of Secondary Power Supply Voltage
(5) Connect the digital voltmeter between test terminals on the CPU-264 and the XPT-16 boards and
confirm that the voltage value of each test connector meet the specification shown in the table below.
If the specification does not meet, adjust the voltage by the adjustment potentiometers of the power
unit B.
(6) Turn on the power switches of the power units A and B.
(7) Confirm that the indicators of the power units A and B light. If an indicator of both does not light, re-
carry out from the step (1) of “procedures for power unit B”.
