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).
Figure 8. LGR-5327 and LGR-5329 counter channel input terminals and input mode switches
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.
