PRODUCT OVERVIEW
The RG1V rotary paddle switch is designed to detect high and low levels of bulk granular solids in bins,
tanks, silos, and as blockage detectors in spouts where failsafe detection is required, or for dust hazard
areas.
The detection of material is achieved by a rotating paddle. If material impedes the rotation of the paddle,
the motor topples of its axis and triggers a contact. The power supply to the motor is cut and the contact
signals that a critical level has been reached, which will cause the motor for any inlet or outlet to close
down or start up. When the level of the material reaches normal levels again, the motor returns to its initial
position and restarts.

INSTALLATION
Before installation, inspect the outer structure of the level gauge. Check the movement of the propeller
shaft and the operation of the clutch assembly. If this check reveals anything irregular, the level gauge
must be reported back to 4B. 4B level gauges can be installed in any position. With the shaft in a horizontal
or vertical position, the level gauge must be mounted with cable glands on the right hand side (Figure 1).
The level gauge is mounted on silos or vessels on the side or top. It is important to choose the position
so that the device is outside of the product ow, likewise taking care that the material can move freely all
around the gauge.
Protective deectors (Figure 2) are advisable when there is considerable weight load on the shaft or when
material ow is unevem and lumps of product may fall down on the probe. The level gauge can be mounted
on the silos via a threaded insert (2” 1/2 BSPP), which is welded onto a silo.

STANDARD WIRING DIAGRAM
All wiring must be In accordance with local and national electrical codes and should be undertaken by an
experienced and qualied electrician.
The conductors forming the power supply and signal carrying cable must have an adequate cross-section
so that the current density, in each conductor, is no higher than 4 A/mm . One of these is used only for the
earthing of the level gauge.
The cross-section of the conductors must also be adequate in relation to the length of the cable used to
avoid a drop in voltage along the cable over the values prescribed by the regulations on the subject. It is
likewise recommended to use exible cables with an adequate outside diameter for the cable entries used
(not supplied) to ensure a correct sealing of the cable gland on the cable.
External ground connection can be found on the outside of the level guage next to the cable entry. It is
realised via M5 screw and eyelet cable crimp.
- The external earthing has to be carried out by the installer.
- The equipment has to be protected against impact and electrostatic inside the silo.
- The user has to protect the equipment circuits with fuses against short circuit.
- The maximum surface temperature is determined taking into account a safety margin, but without
considering a possible dust deposit on the equipment.
WARNING
Use exclusively cable glands certied according to directive 2014/34/EU, Category 2 and EN60079-
31 (as applicable).
The terminal box contains a screw which is marked by the earth symbol (Figure 3). This screw
must be connected to the Earth core of the power cable. The earth connection of the level gauge is
compulsory.

NOTE
4B Rotary level indicators need no routine maintenance. Possible extraordinary maintenance is restricted
to replacing parts that are deteriorated by use. The gauge must not be lubricated, the shaft, the only
moving part is mounted on ball bearings with permanent lubrication.

TESTING AND COMMISSIONING
1. Follow the safety rules below when installing this product.
2. Check that the unit is correctly installed (see standard wiring diagram).
WARNING
All the appropriate safety precautions must be taken when electrically operated equipment is used, in
order to reduce the risk of re outbreaks, electric shock and injuries to persons.
- Keep the work zone clean and orderly. Accidents are more likely to occur in untidy areas and
environments.
- Before beginning work, make sure that the level gauge is in a perfect condition. Damaged or broken
parts must be repaired or replaced by competent personnel authorized by the Manufacturer.
- All verications, inspections, cleaning and maintenance operations, part changes and replacements,
must be carried out with the level gauge disconnected and the plug removed from the power socket.
- It is absolutely forbidden for children, unauthorized and/or inexperienced persons to touch or use the
level gauge.
- Make sure that the electricity system complies with the laws in force. Make sure that the earthing is
e󰀩ciently connected when the instrument is installed.
Make sure that the power socket is suitable, that it complies with the laws in force and that it has a built-
in automatic protection circuit-breaker. The level
gauge must never be stopped by detaching the plug; moreover, never use the cable to pull the plug
from the socket.
- Periodically check to be sure that the cable is in perfect conditions and replace it if damaged. This
operation must only be carried out by competent and
authorized persons. Only use extension cables of the permitted type and marked.
- Do not allow children or unauthorized persons to touch the cable when the instrument is plugged in.
- The models with signal lamp must be protected from direct exposure to sunlight.
