Level controller for conducting liquids
WLS-GEH230V
2.4 Scope of supply
Die Lieferung des Geräts erfolgt inklusive Messfühler-Anschlusskabel, 6-polig mit RJ12 Steckverbinder, jedoch ohne Elektroden. Stan-
dardfühler sind als Zubehör erhältlich oder können leicht selbst hergestellt werden. Die Lieferung der 12 V / 24 V Ausführung erfolgt
als Modul (Platine) 95 x 75 mm ohne Gehäuse und ohne Bedienteil. Die 230 V Ausführung wird komplett eingebaut im Gehäuse mit
integriertem Netzteil und mit Bedienteil geliefert. Die Außenabmessungen betragen 100 x 100 x 60 mm. Die Kabelverschraubungen
werden mitgeliefert.

3.1 Electrical connection
3.1.1 Safety instructions
!
Caution! Touching the high voltage parts may lead to fatal dangers. The mounting and maintenance operations should be carried out
by only trained personnel, who are authorised on the basis of technical training in this eld. The applicable safety regulations are to be
duly followed! The switching device must be assembled in a switching cabinet or in a fully closed plastic housing. Mounting and servicing
operations should be carried out only after switching off the voltage. The device should be mounted only at dry locations!
!
Due to wrong tightening of screws of the connection terminals or by use of inappropriate tool, the terminals can get damaged because of
which the insulation or the contact can get disturbed. Badly connected leads can come out during operation and cause a serious risk to
safety. Due to contact resistance at terminal connections, there can be increased heat generation which can cause re. Wrongly wired
connections can destroy electric components and cause other damages.
3.1.2 Lines to the sensor set-up
The RJ12-plug connector has been provided for direct connection of sensor lines to the unit. The connector is led through a cable gland
provided in the housing and properly mounted through M16 threads. The connection of the ready sensor is to be done as per enclosed
data sheet. The connection length of self made sensing set-up should not exceed 5 m. For short connection lengths up to approx. 3 m,
a simple unshielded cable (5-core) is quite suitable. For larger lengths or in EMV-critical environment, shielded cables should be used.
The shielding should be connected to COM (reference electrode). In long connection lines, the electrode input may change due to line
capacitance. This can be adjusted through potentiometers. If necessary, the adjustment should be checked again after any modication
in line length.
