16.3.4.1 DEF Level Gauge Requirements
In addition to the specific DEF system indicators described in table 16.8 the
machine must also be fitted with a DEF level gauge. Whilst specific DEF level
gauge requirements may differ between geographical machine operating
territories, Perkins require a DEF level gauge to be constantly visible. The
layout of the gauge is dependent upon the customers’ requirements however
as a minimum the ‘RED’ or low DEF fluid section of the gauge must start at
20% remaining (point at which the low DEF level indicator is activated).
