Screw terminal LED functions
The functions of the LEDs associated with screw terminals are explained below.
 The LED for each active digital connection is on when voltage is detected.
 The LED near the
PWR+ terminal is on when the relay is energized
 The LED for each analog input terminal is on if the associated channel is in the scan list.
On the LGR-5327 and LGR-5329, you can configure the encoder counter inputs as single-ended or differential
mode using the switches that correspond to each pair of phase A, phase B, and Index terminals (see Figure 8).

 To configure a counter channel for single-ended mode, slide the switch to the right. Note that the "dot" is
visible on the switch when a channel is configured for single-ended mode.
 To configure a counter channel for differential mode, slide the switch to the left.
