SAM TROUBLESHOOTING PROCEDURES
Three SAMS are provided:
SAM 1 - Initial Troubleshooting Procedure
SAM 2 - AC to DC Converter Circuit Breaker Tripped
SAM 3 - Fault Indicators
The intent of these SAMs is to aid in isolating the cause when the AA161-A
fails to power up when the ON switch is pressed. When troubleshooting, begin
by perfonning the Initial Troubleshooting Procedure (SAM 1). This SAM
references the other SAMs.
WARNING
Hazardous voltage is present in the AA161-A.
Therefore, be cautious while working on the
equipment.
WARNING
If the battery ride-through option is present
and if the BATTERY DISCONNECT breaker is on, the
batteries maintain dangerous current after the
wall circuit breaker is turned off.
Refer to the section of this manual titled, Field Removal and Replacement for
appropriate procedures. Refer to schematic diagrams in the CYBER 180 Models
810 and 830 Power Distribution and Warning System manual as necessary when you
are using the SAMs.
