13.2) Limits of operation
▲ WARNING: The lubrication system has to be designed such that operating
temperatures will not exceed the specified limits.
Oil pressure: For oil pressure sensor see Fig. 93/94.
see OM 914 Serie, section 10.1
Oil temperature: Oil temperature sensor, see Fig. 91/92.
see OM 914 Serie, section 10.1
▲ WARNING: At operation below nominal oil temperature formation of condensate
in the lubrication system might influence oil quality.
◆ NOTE: For operation at low temperatures the installation of an oil thermo-
stat, parallel to the oil cooler, is strongly recommended.
Advantages: safe oil pressure after cold start, prevention of fuel and
water accumulation in the oil.
