Simplified Drawing
The power for the servo motors for the APF instrument is provided by a pair of Kepco HSP 48-21MR 48 volt supplies. The supplies are sized and arranged such that if one were to fail the other supply is capable of powering all of the servos. The supplies are each powered via a separate Pulizzi channel. That is, supply one is on Pulizzi channel 3 and supply two is on channel 4. Note that while the Pulizzi power controller can be controlled via software, it is set for default operation at power up - that is, channel 1 comes on first then about a second later channel 2 come on and so forth until all 8 channels have come on.
As is depicted on the left side of the above drawing, each supply has one control input and four status outputs. The ~SET_48V_OFF signals can be used to inhibit the DC output of the supply. When held low, the output voltage is removed, the DC FAIL indicator on the front panel of the supply comes on, and the 48V_OUTPUTn_FAILED signal goes high. The AC_PWRn_FAILED signal goes high if power is removed from the unit. Note that if the AC power is removed from the supply the three other output bits are invalid. The 48V_FANSn_FAILED and 48V_TEMPERn_FAILED signal states can not be tested but the wiring is tested by removing the power supply's I/O connector. When removed, these two inputs float high.
