11.4 - Oil level switch with float

II 1 G Ex d IIC T6

II 2 G Ex d IIC T6

It is a level control device with reed contacts in a supporting stem moved by

the magnetic field activated by the magnets included in the float.
The float and the supporting stem are included in a hollow column of

not magnetic material connected to the gear reducer casing through

communicating vessels.
Features:
- 2 wires connection;
- Max voltage: 350 V
- Maximum current: 1.5 A
- 1 cable input 1/2” UNI6125 – IP65
- G 1” brass joint.

Installation and maintenance

The accessories used for cable input and for covering unused holes must be

certified according to EN 60079-0 and EN 60079-1 standards.
The level switch must be installed and maintained according to plant and

maintenance standards for environments classified to explosion proof for the

presence of gas (i.e.: EN 60079-14, EN 60079-17 or other national standards).

The level switch box must be earth connected.
Only proper tools have to be used for installing and disassembling the level switches. Never use electrical

connections for manual installation.
The level switch cables must be installed in mechanical protections such as conduit pipes with separating

joints at the top and the end of the pipes. Minimum cable section has to be 0,22 mm

2

. All active/passive

safety barriers and connected devices (insulated amplifiers, relays) if any must be certified according to

EN 60079-11 standards with [EEX ia] IIC protection and have to be installed in a safe area. The contacts are

“REED” type and can carry up to ca. 100 000 000 operations during their life cycle. The switch power is

relatively low (30-100 VA/W depending on application). For the safe use of the contacts it is recommended

to drive inductive/capacitive power-loads through auxiliary relays or to use transient dampers/ Suppressors

If used in accordance with its mechanical and electric specifications, this series of instruments does not

need any specific maintenance. Check every 6 months the functionality of the level switch according to

table 12.3. Protect the switch head if there may be a risk of hurts with foreign matters.

Setting

The switch is supplied ready for use; when level goes down approx 5 mm, the switch goes on and contact

opens.

When filling oil in the gear reducer it is necessary to verify that device is properly set.

If any problems occur during this operation contact Rossi.
