LED1
State
indicator
On: The expansion card is establishing a connection with the
control board.
Blinking periodically: The expansion card is properly
connected to the control board (the period is 1s, on for 0.5s,
and off for the other 0.5s).
Off: The expansion card is disconnected from the control
board.
LED2
Disconnection
indicator
This indicator blinks only if A1 or B1 signal is disconnected
during encoder rotating; and it is on in other cases.
LED3
Power
indicator
On: The control board feeds power to the PG card.
EC-PG505-24 can work in combination with multiple types of incremental encoders through various
