Minimum Or Obligatory Safety Measures; Failure Of The Measurement Signals; Table Of Minimum Engine Safety Measures - Kohler SFGLD480 Operation & Maintenance Manual

1. INTRODUCTION
This document compiles the different variables that can be recorded on a FG/FGLD/SFGLD/SFGM/SFGRD
engine with a view to setting up an operating safety chain. We classify the safety features in order of importance
within two groups as follows:
-

Minimum or obligatory safety measures

- Additional signals
Of a general nature, this document does not apply to special cases in which the values shown in the next tables
may vary due to production requirements, prevailing regulations, characteristics of the plant, or fuel quality, etc.
2. MINIMUM OR OBLIGATORY SAFETY MEASURES

2.1. FAILURE OF THE MEASUREMENT SIGNALS

Failure of the measurement signals of any of the sensors used should be treated as non-compliance with the
minimum or obligatory safety measures of the engine. With a failure of this kind, you should initiate a gradient
shutdown of the engine.
With the 4-20mA analogue signals, the control equipment must be able to detect cable breakage and/or
interpret a reading outside the 4-20mA range as a failure of the measurement signal. Gradient shutdown of the
engine due to analogue signal failure can be timed as long as the fault is maintained for over 10 seconds.
With potential-free contacts, as all of them are NC (Normally Closed) type in operation without alarm, a broken
cable or failure in the signal should initiate a gradient shutdown of the engine.

2.2. TABLE OF MINIMUM ENGINE SAFETY MEASURES.

Table 1 shows all the obligatory safety measures that must be configured in the engine control equipment.
WARNING
If the configurations shown in the table are not complied with and said non-compliance leads to a fault
in the engine, the client shall be held responsible for all damage caused.
