circulating in the heat exchangers is too high.
- Red [Fig. 4 Ref. 8] pilot light, when on, indicates that
the alternator windings have reached too high tem-
peratures.
- Yellow [Fig.4, Ref.11] pilot ligh,when on, indicates
that the glow plugs are active.
The following may also be found on the control panel:
- A bipolar magnetothermal switch [Fig. 4 Ref. 2]
which cuts the power in case of an overload or short-
circuit.
- A thermal switch (Fig. 4 Ref. 3] to protect the low-
voltage electric system against short-circuit.
- An hour counter (Fig. 4 Ref. 1].
- The generator start/stop button [Fig. 4 Ref. 4].
The generator can be connected with a connector to the
remote starting panel, [Fig. 3 Ref. 24] supplied by mase
as an optional, and can be installed on the dashboard.
Two different remote starting panels are available as
shown in Fig. 5.
The most simple version has a start/stop button [Fig. 5
Ref. 1] and a green pilot light [Fig. 5 Ref. 2] which, when
on, indicates that the generator is running.
The second version of the remote starting panel [Fig. 5
Ref. 3] has, in addition to the start/stop button, an
instrument which indicates the engine oil pressure value
(Fig. 5 Ref. 4] and an instrument which indicates the
coolant temperature value [Fig. 5, Ref. 5].
When carrying out maintenance
operations on the generator, disconnect the negative
pole of the starter battery to prevent accidental
starting.
