Indicator definition:
Indicator Definition Function
LED1 Status indicator
This indicator is on when the extension card is establishing a
connection with the control board;
it blinks periodically after the extension card is properly
connected to the control board (the period is 1s, on for 0.5s,
and off for the other 0.5s);
and it is off when the extension card is disconnected from
the control board.
LED2 Power indicator
This indicator is on after the control board feeds power to the
PG card.
LED3
Disconnection
indicator
This indicator is off when A1 and B1 of the encoder are
disconnected; it blinks when C1 and D1 of the encoder are
disconnected; and it is on when the encoder signals are
normal.
