Specifications

• If LED CR48 on SPSM is still not lit, check cable assembly 6 and
the bridge rectifier.
NOTE
The voltage (12 V ) indicated by CR10 is 12 V above
the rectified output zero (z) and is not 12 V above
ground.
• If LED CR48 (top) on SPSM is not lit, replace SPSM.
5. Check the SPSR output voltages by disconnecting P3 of CA8, and
measuring the voltages at the connector. The voltages are:
PWR-UP
-12V
12V
5.1V
42V
0V
P3-6
P3-3
P3-10
P3-8
P3-1, P3-12
P3-2, P3-5, P3-7, P3-9, P3-11
