7.0 INITIAL POWER UP AND INSPECTION
7.1 General
The 20 kHz HF APR system comes in a standard configuration with typical default
calibration values stored in memory. If required, the factory defaults can be reloaded into
memory. After initial inspection and interconnections have been made, the system will be
ready for power up, voltage checks and calibration.
WARNING: The main storage capacitors retain their charge for some time after
the unit is turned off. Although the areas where this voltage may be present are
covered with a protective layer of Lexan, it is imperitive that all service personnel
are respectful of the significant shock hazard the capacitor bank voltage
represents. Prior to servicing the power components, ensure that the LED on
the Charge Monitor PCB is not lit, and verify there is no capacitor bank voltage
with a DC voltmeter
.
7.2 System
Configuration
System configuration will be done via the Operator’s Console in the utility section of the
power module set up screen, and also the DIP switch settings located on the system
controller board (01003-000) and APR console board (L510).
Observe DIP1 on the System Controller PCBA in the Power Module and DIP2 on the APR
Console PCBA in the Operator’s Console, and verify that all switches are set to their
default settings. Refer to the chart below for information on the functions of the switches.
