5.6

Heating element on ex-version

If heating elements are designed explosion-proof, the gear unit is additionally equipped with oil-level
monitoring by means of a level limit switch. This monitoring checks the oil level of the gear unit for the
submersion of the heating rods (see item 5.6.1).

5.6.1

Oil level monitoring of the heating elements

The gear unit is equipped with oil level monitoring. This monitoring system checks the oil level in the gear
unit (minimum oil level for immersion of the heating rods).

The "Oil level too low" signal must be wired so that the heating elements are switched off when the signal
is given. This ensures that the heating elements are not operated if these are not completely immersed.

DANGER

Explosion and fire hazard

Fire hazard or ignition of an explosive atmosphere by exposed heating rods is possible.
Never switch on the heating elements, unless complete immersion of the heating element in the oil bath
is ensured.
If heating elements are installed afterwards, the maximum heating capacity (see table 7) on the outer
surface of the heating element must not be exceeded.

A detailed illustration of the gear unit and the position of the add-on parts can found in the drawings of the
gear unit documentation.

Note

Be sure to observe the operating instructions of the oil level monitoring device for operation and
maintenance.
The technical data and control information can be found in the data sheet prepared specially for the
order or in the equipment list.

5.7

Indication of oil level

The gear unit is equipped with an oil level indicator (oil-level indicator with MIN and MAX mark) for a visual
check of the oil level at standstill. The oil level is checked when the oil has cooled down (on the oil level
indicator).

A detailed illustration of the gear unit and the position of the add-on parts can found in the drawings of the
gear unit documentation.
