Technical information / Instruction manual
Introduction
The ROTONIVO is an electromechanical Level limit switch and
is used for level monitoring of bulk goods.
The units can be delivered with a wide range of Ex-approvals
for use in Hazardous Areas.
They can be equipped for process over- and lowpressure and
also for very high or low process temperatures.
Selected applications:
• building materials industry
lime, styrofoam, moulding sand, etc.
• food industry
milk powder, our, salt, etc.
• plastics industry
plastics granules etc.
• timber industry
• chemical industry
• mechanical engineering
The ROTONIVO is normally screwed into the lateral container
wall so that it is in level with the lling height to be registered and
monitored.
The device can also be mounted from the top of the container. In
this case an extension piece is used to mount the probe level with
the height to be registered.
The length of the probe can be up to 4 m (158") with an extension
tube or up to 10 m (394“) with an extension rope.
The use of a sliding sleeve for the version RN 3002/ RN 6002 is
recommended so that the switch point can be changed easily
during operation of the device.

Technical information / Instruction manual
Function
A measuring vane is driven by a synchronous motor. The
bearing of the motor inside the housing allows it to swing. The
motor is xed to a switching lug.
If the vane is uncovered, a spring pulls the motor and switching
lug to the left position (gure 1).
When material covers the vane and thus stops the rotation, the
motor and switching lug swings to the right position (gure 2).
The signal output indicates "covered" and the motor is stopped.
When the vane becomes uncovered due to falling material,
the spring pulls the motor and switching lug back to the left
position (gure 1). The motor is started and the signal output
indicates "uncovered".
Fail safe alarm
With the option fail safe alarm it is possible to recognize a fault of
the unit in time and to initiate an alarm relay. The following faults
are observed:
• Motor
• Gear
• Electronic for motor power supply
• Supply voltage failure
• Defect of the connecting wires
Functional safety SIL2 (IEC 61508)
With option Functional safety the unit observes the motor, gear
and electronic. The result of this diagnostics is present on the
signal output, which states the full/ empty condition.
Switchable signal output (Fail safe high/ low)
With version "Universal voltage", "PNP" and optional "AC" a
switchable signal output FSH/ FSL is integrated.
Signal output delay:
The version "Universal voltage" and "PNP" has an integrated
adjustable delay for the signal output.

Process pressure Improper installation may result in loss of process pressure.
Chemical resistance
against the medium
Materials of construction are choosen based on their chemical compatibility (or inertness) for
general purposes. For exposure to specic environments, check with chemical compatibility
charts before installing.
Mechanical load The torque at the fastening spot must not exceed the specied ratings. See page 12 for details.
Mounting location Keep away from incoming material and from silo walls.
The installation has to be carried out, that the sensor elements cannot hit the wall of the silo. The
ow of the medium and xtures in the container must be considered. This is especially important
for extension length of more than 3000 mm (118“)
Sliding sleeve Tighten both straining screws M8 with 20 Nm

Precaution for later
dismounting/ Service
• Use teon tape to avoid seizing of aluminium process connection thread with the socket
• Grease the screws of the lid if corrosive atmosphere is present (e.g. close to sea)
EHEDG-Approval Seal the thread with teon tape against process pressure.
Metal-metal sealing:
• The support muß be plane and without any gap. No teon tape (or similar) is allowed to be in
between.
• Fixing torque 100 Nm
The quality of the welding with the container wall must be according to the respective
regulations (e.g. gaps, transitions, surface nish).

Electrical installation
Handling In the case of improper handling or handling malpractice, the electric safety of the device cannot be
guaranteed.
Installation regulations The local regulations or VDE 0100 (Regulations of German Electrotechnical Engineers) must be
observed.
WIth use of 24 V supply voltage, an approved power supply with reinforced insulation to mains is
required.
Fuse Use a fuse as stated in the connection diagrams (see pages 23 and 24).
RCCB protection In the case of a fault, the supply voltage must be automatically switched off by a RCCB protection
switch to protect against indirect contact with dangerous voltages.
Power supply switch A voltage disconnection switch must be provided near the device.
Wiring diagram The electrical connections are made in accordance with the wiring diagram.
Supply voltage Compare the supply voltage applied with the specications given on the electronic module and name
plate before switching the device on.
Cable gland The screwed cable gland and closing element must have following specications:
Ingress protection IP66, temperature range from -40°C to +70°C, UL or VDE or INMETRO certied
(depending on the country where the unit is installed), pull relief. Make sure that the screwed cable
gland safely seals the cable and that it is tight (danger of water intrusion). Cable glands that are not
used have to be sealed with a blanking element.
The diameter of the eld wiring cable has to match to the clamping range of the used cable gland.
Conduit system In case of using a conduit system (with NPT thread) instead of a cable gland the regulations of the
country, where the unit is installed, must be observed. The conduit must have a tapered thread either
NPT ½“ or NPT ¾” in accordance with the unit and ANSI B 1.20.1. Not used inlets must be closed
tight with a metal blanking element.
Field wiring cables • The diameter has to match to the clamping range of the used cable gland.
• The cross section has to match with the clamping range of the connection terminals and consider
the max. current.
• All eld wirings must have insulation suitable for at least 250 V AC.
• The temperature rating must be at least 90°C (194°F).
• If higher immunity interferences as specied in the stated EMC standards are present (see chapter
approval), a shielded cable is required, otherwise an unshielded instrumentation cable is
satisfactory.
Guiding the cables in the
terminal box
Cut the eld wiring cables to appropriate length to t properly into the terminal box.
Microswitch protection Provide protection for microswitch contacts to protect the device against inductive load surges.
Protection against static
charging
The housing of the unit must be grounded to avoid static charging of the unit. This is particularly
important for applications with pneumatic conveying and non-metallic containers.
