2.24 Pilot lamps unit with a molded dashboard
Pilot lamps unit 4 (Figure 2.23.1) includes three lamps. The arrangement diagram is
presented in Figure 2.24.1.
1 – pilot lamp to indicate that the air cleaner filter is clogged to the max. (orange
color); 2 – pilot lamp to indicate emergency oil pressure drop in the system of hydrostatic
power steering (red color); 3 – pilot lamp to indicate operation of heating plugs (orange color)
Figure 2.24.1 – Pilot lamps unit
The operation principle of the pilot lamps in the pilot lamps unit is the following:
- pilot lamp 1 to indicate that the air filter is clogged to the max. (Figure 2.24.1) lights
up when the max. permissible level of filter dirtiness is exceeded and the filter requires
cleaning;
- pilot lamp 2 to indicate emergency oil pressure drop in the hydraulic system of hy-
drostatic power steering lights up when oil pressure in the hydraulics of hydrostatic power
steering drops below 0,08 MPa (periodic lighting up of lamp 2 with engine minimal speed is
assumed – when revolutions are increased lamp 2 should go out);
- pilot lamp 3 indicates heating plug operation (functioning algorithm of the pilot lamp
indicating heating plug operation is provided below).
