Litz contact only by means of connector sleeves with insulating
enclosures for reasons of shock protection according to EN 61010.
Do not otherwise assign contacts that have been left unassigned ex
factory. We recommend to screen all sensor terminal leads and to
ground the shield on one side. Shields on both sides are recommen-
ded in case of RF interference or in case of equipotential bonding
over long distances. The sensor leads should not be in the same
phase winding as the mains supply and the output contact leads.
3.1 Voltage supply connection
Three voltage supply are available:
AC voltage: 24/48 VAC (50/60 Hz), set the required alternating vol-
tage with the voltage selector switch.
AC voltage: 85...265 VAC (50/60 Hz), wide range supply
DC voltage: 12...30 VDC

➜
Model 24/48 VAC: set the required alternating voltage with the
voltage selector switch.
➜
Connect AC at the contacts 1 and 2 according to the terminal
diagram.
DC-voltage 12...30 VDC:
Connect interference-free voltage supply. Therefore, do not use the
voltage supply for parallel supply of drives, contactors, electroma-
gnetic valves, etc.
Fire protection: Operate instrument on the MAINS with external fuse
recommended on the type label. In case of disturbance, make sure
that 8 A /150 VA (W) are never exceeded – as defined under
EN 61010.

Contact P1
The signal outputs (contacts 3, 4 and 5, 6) are floating relay
contacts. The signal outputs can be assigned as per the adjacent
terminal diagram.
The type of outputs, as momentary or latched signal, can be cho-
sen in the programming lines 41/42.
Their function, as normally open or closed, is selected in program-
ming line 40.
