Electrical Parameters of Digital Outputs, Multi-Function Connection

The digital outputs require an external auxiliary voltage between 5 V and 30 V as well as load resistance. They can be
operated at a load current of at most 100 mA. This may occur, for example, by using an NPN-switching input module of a
control.
The outputs are switched using a SolidState relay and are low active.

Installation Instructions

For all connection cables, use only the appropriate cables from the optional accessories.
Tighten the cable connectors. The recommended tightening/screwing torque is at most 1.0 Nm.
Do not apply force when tightening.
> Damage to or destruction of the sensor
Lay all connection cables in accordance with the generally applicable measuring technology regulations, i.e. for example
not directly next to pulse-carrying lines, preferably in a separate cable duct.
Never bend the cables more tightly than the minimum bending radii.
MICRO-EPSILON recommends using the optionally available power supply PS2020, installation of top-hat rail,
input 230 VAC, output 24 VDC/2.5 A, see Appendix.

Commissioning

The sensor may only be connected to peripherals when it does not carry power, that is, only when the
operating voltage has been switched off.
Mount the sensor according to the installation instructions, see
Connect the sensor to the Ethernet cable.
Connect the Ethernet cable to the PC.
Connect the sensor to the power supply.
