Calibration
Power Supply Calibration
DC Power Supply PS1
Calibration of Power Supply PS1 consists of checking each output for proper voltage under load, and making adjustments to the
high-current +5.1 Volt output, if necessary. Calibrate the supply when you replace it, and semiannually as described in the
periodic maintenance procedures.
WARNING:
Dangerous AC voltages are present on connector J1 of Power Supply PS1 during the following calibration
procedure.
CAUTION: Be careful when making the following measurements. Short circuiting a DC output can cause burns
and equipment damage.
Note: Make sure PS1 is fully installed with all loads connected before performing the following calibration procedure.
Calibrate DC Power Supply PS1 as follows:
1. Remove Left Side Cover.
2. Loosen and remove two torx screws and lockwashers that secure swing-out panel to left-hand side of generator chassis.
Swing panel away from chassis to expose PS1.
3. Make sure Workstation’s AC power plug is connected to facility AC outlet.
4. Turn Workstation on and allow system to boot.
5. Check output of high-current +5.1 Volt supply at J2-1. Output must measure 5.1 (+.1) Volts. If output is within range, go to
step 7. If output needs adjustment, go to next step.
6. Adjust R51 until output measures 5.1 (+.1) Volts. If you can’t adjust PS1 to produce a satisfactory 5.1 Volt output under
normal load conditions (<8 Amps), replace PS1.
