ESCRIPTIONS

Figure 4 shows the PCU-796 front edge indicators.

 

One green POWER LED and four yellow CONDITIONER 

LEDs are present. The POWER LED is green when the -48 V office battery and battery return are present at the 
card edge pins. If fuse F1 blows, the POWER LED goes off and -48 V office battery is applied to the Fuse Alarm 
pin on the card edge connector.

The yellow CONDITIONER LEDs go on when one or more of the conditioner circuits sense current flow on the 
PGTC sleeve lead output (see Table 1).
