Maintenance and Alignment
5.13.2 Replacing the Power Supply Controller Board
Replacement of a PS Controller Board requires no analog adjustments. Set all dip
switches and jumpers to the same position as the board being replaced. If the new
board does not have the firmware IC’s already installed, then the firmware will have
to be transferred from the old board. Refer to "5.15 Removing/Replacing Firmware
ICs" on page 5-24.
The following is a listing of the normal dipswitch and jumper settings:
a. For PSC #1 - All switches OFF
b. For PSC #2 - S1-1 ON, all other switches OFF (PSC #2 is optional in a Z5)
c. JP1 pins 1-2
d. JP2 pins 1-2
5.13.3 Replacing a PA Controller Board
Replacement of a PA Controller Board requires no analog adjustments. Set all dip
switches and jumpers to the same position as the board being replaced. If the new
board does not have the firmware IC’s already installed, then the firmware will have
to be transferred from the old board. Refer to “Removing/Replacing Firmware IC’s”
later in this section. The following is a listing of the normal dipswitch settings for
S1 on each PA Controller:
a. For PAC #1 - All S1 switches OFF.
b. For PAC #2 - S1-1 = ON, all other switches OFF.
NOTE:
The switches set the board ID #. Once the ID for the board has been set, it
must be placed in the proper slot and the correct cables connected to that #
controller. An improper ID or incorrect cabling will generate cable or jumper
faults in the Fault Log and the transmitter will not turn on.
