Hitachi Zx250lc-5b And Zx250lcn-5b Zaxis Excavator Manual

1. When key switch (7) is set to START position (6), terminal B is connected to terminals M (8) and ST (9) in key switch (7).
2. Current from terminal M (8) excites battery relay (4) through key switch ON cut relay (10). Current from battery (1) is routed to terminal B of starter (2) and terminal B of starter relay 1 (3) through battery relay (4).
3. In addition, current from terminal M (8) in key switch (7) flows to fuse #17 through key switch ON cut relay (10).
4. Current from fuse #17 flows to GSM (11), monitor controller (13), ECM (15), and MC (16) as a signal indicating that key switch (7) is in ON or START position (6).
5. When ECM (15) receives this signal, ECM (15) turns ECM main relay (14) ON.
6. Current from battery (1) flows to ECM (15) through fuse #8 and ECM main relay (14), and the ECM (15) main power is turned ON.
7. ECM (15) makes the engine starting condition.
8. Current from terminal ST (9) flows to terminal S in starter relay 1 (3) through starter cut relay (5).
9. Current flows to the coil in starter relay 1 (3) and starter relay 1 (3) is turned ON.
10. Therefore, current flows to terminal S in starter (2) from terminal C in starter relay 1 (3).
11. Consequently, the relay in starter (2) is turned ON so that the starter motor rotates.
