To adjust the display voltage

This procedure adjusts the A102 DC-DC Converter assembly’s display voltage to match the voltage required by the A101 Display assembly. This adjustment is only required when the DC-DC Converter assembly or the Display assembly is replaced.

Equipment Required: Multimeter

The display voltage is +210 Vdc 10 Vdc nominal. Use caution when performing this adjustment to avoid personal injury.

•Set the power switch to off ( O ).

•Record the V(ALL ON): voltage.

The V(ALL ON): voltage is printed on a sticker on the component side of the Display

assembly. The V(ALL ON): voltage is normally between +200 Vdc and +220 Vdc.

Do not adjust the display voltage above +230 Vdc. The Display assembly can be damaged if the voltage is adjusted above +230 Vdc.

•Turn A102 R25 clockwise to its stop.

•Set the multimeter to a range greater than 220 Vdc and connnect to A102 TP1 using a shielded test clip.

•Set the power switch to on (I ).

•Using a non-metalic flat-edge adjustment tool, adjust A102 R25 for the voltage recorded in step 2.

•Set the power switch to off.
