LED Lines

The EM1000 has four LED control lines — SG, SR, EG, and EY. All lines have the same internal structure and the LEDs should be connected to these lines as shown in the schematic diagram below. The maximum load for each line is 10mA.

Further information on status LEDs can be found in Status LEDs.
