9.6 DC Power Supply

Overall performance of the DC power supply may be checked by observing the value displayed

during test DCPS. If this value, a composite of the five (5) regulator outputs, deviates by more

than 10% from the value recorded in Table 1-1 of this manual under Test Values, the outputs of

the individual regulators should be measured.

Test points 1, 2, 3 and 4 provide connection to the temperature outputs on drawing no. 00016 in

Appendix C.

9.7 CPU

If the display is operating and the green sample light is on, the CPU should be operating. If not,

check for +5 v to the CPU. Refer to Section 10.6.4 Checking DC power supply.

CAUTION

Do not disconnect CPU or other digital cards while under power.
