Electrical Connections und LED Function
4.1.
Power Supply and LEDs
The device is supplied with 10 to 30 VDC about the 2-pin screw terminal strip (X1) on the front
of the device. The current consumption is approx. 25 mA (no-load operation).
The upper LED (green) signals that power is applied to the unit.
The lower LED (yellow) signals a possible error (e.g. wire break) at the input channels A, /A, B,
/B and/or Z, /Z in case of differential input signals, switched on error evaluation (DIL 3 = ON)
and corresponding terminated wires.
More detailed information about the error evaluation can be found in the chapter "Error
evaluation".
4.2.
Auxiliary Encoder Supply
The 9-pin input terminal on the front panel (X2) provides a short-circuit proof +5VDC and a
+24VDC encoder supply. There is no electrical separation between encoder supply and device
supply.
