System Operation
PCB1 Timing and Trigger Board
PCB1 governs all automatic functions. Two differ-
ent PCB1 boards are used in the PC 312-3 Power
Converter. The 24740xx board is used in all
except the “AE” models. The 24747xx board is
used in the “AE” models. The “xx” in the board’s
part number refers to its dash number, which
changes with the board’s internal programming.
The major difference between the two is their
jumpers, internal control and programming. Addi-
tionally, PCB1 for EagleWin “E” systems connects
to a telephone line for remote monitoring by com-
puter. The factory sets the jumpers and programs
PCB1 before it leaves the factory.
Setting Up PCB1
Function Indicators
LED indicators on the PCB1 board signal alarms
and internal functioning. Observe these LEDs to
monitor equipment operations during checkout
and troubleshooting. The essential features on
PCB1 for troubleshooting are shown in Figure 1-2
and Figure 1-3.
PCB1 24740xx
PCB1 (24740xx) has the following features:
•
LED indicators indicating function
•
A neon lamp indicating trigger power
•
Jumpers for external programming
•
An RS-232 socket for internal programming
Refer to Table 1-2 for indicator and lamp func-
tions, and Table 1-3 for jumper settings.
PCB1 24747xx
PCB1 (24747xx) has the following features:
•
Twelve LED indicators indicating function
•
One neon lamp indicating trigger power
•
Two jumpers for external programming
•
One RJ11 telephone line socket for remote
EagleWin monitoring
•
One RS-232 socket for internal programming
Refer to Table 1-4 for indicator and lamp func-
tions, and Table 1-5 for jumper settings.
