2 Function
Electrical connection
The unit must be connected by a qualified electrician.
► The national and international regulations for the installation
of electrical equipment must be adhered to.
► Ensure voltage supply to EN 50178, SELV, PELV. The following
indications apply if there is a UL listing mark on the product: ►
For use in NFPA 79 applications only. Adapters providing field
wiring means are available from the manufacturer. Refer to
manufacturers information.
► The device shall be supplied from an isolating transformer having
a secondary Listed fuse rated a) max 5 amps for voltages 0...20
Vrms (0...28.3 Vp) or b) 100/Vp for voltages of 20...30 Vrms
(28.3...42.4 Vp).
Installation
Settings
The unit and the parameters are set via the operating elements (→
6.2).
For selected units, setting can be done via IO-Link (→ 6.1).
6.1 IO-Link This unit has an IO-Link communication interface which
enables direct access to process and diagnostic data. In addition
it is possible to set the parameters of the unit while it is in
operation. Operation of the unit via an IO-Link interface requires
an IO-Link master. With a PC, suitable IO-Link software and an
IO-Link adapter cable communication is possible when the system is
not in operation. The IODDs necessary for the configuration of the
unit, detailed information about process data structure, diagnostic
information, parameter addresses and the necessary information
about the required IO-Link hardware and software can be found at
www.ifm.com. To set the sensor via IO-Link, the parameter [L-r]
must be changed from [local] to [remote] via IO-Link.
6.2 Operating elements 6.2.1 Setting of the output function
Operation
► Check whether the unit operates correctly.
> The yellow LED is lit when the output is switched.
Maintenance, repair, disposal
► Keep the lens of the sensor free from soiling.
► For cleaning do not use any solvents or cleaning agents which
could damage the lens.
► After use dispose of the unit in an environmentally friendly way
in accordance with the applicable national regulations. Faulty
sensors must only be repaired by the manufacturer
