All faults require a customer connected contact to the MEC 2 input terminal as
indicated. All fault circuits may be user field programmed for different control
functions or alternate fault names.
Note: Shutdown functions for Low Oil Pressure and High Engine Temperature
may alternatively be provided via analog pressure and temperature sender inputs
if programmed accordingly in the analog fault programming menu. Refer to
Section 9.4
for further information.
4.4. ANALOG FAULT INPUT CIRCUITS
The MEC 2 Engine Controller provides up to eight analog fault input circuits that are user
programmable. Each analog fault input circuit is activated via specific analog signal
type.
WARNING!!!
The analog protection circuits for voltage, frequency, current,
engine oil pressure, engine temperature and engine speed will be
set at factory default settings only. Final settings will be required to
be set by the commissioning authority. Failure to do so may result
in severe equipment failure or damage.
4.4.1. ANALOG FAULT CIRCUITS
The MEC 2 is supplied from the factory with fifteen standard analog fault circuits
as follows:
