100 of 148
For mechanically-connected engines, once the maximum is reached it will
continue to display the maximum unless the hourmeter is reset through an
authorized dealer.
J1939 has the priority; it overrides the local engine hour value when the GSC400
is connected to J1939.
4.11 J1939
This section applies if J1939 is enabled for one or more parameters. The
parameters are displayed the same for J1939 as they are for analog inputs. The
only difference is that when a parameter cannot be read from the J1939 bus the
text “N.A.” is displayed in place of the parameter value.
If the Loss of ECM setting is enabled, the GSC400 will shut the generator down
on “Loss of ECM” if no communications are detected on the J1939 bus for the
parameters the GSC400 monitors for.
