Power source control circuit for working machine |
摘要 |
<p>A power source control circuit for a working machine includes an electric circuit connecting a key cylinder (3), controller (6) and accessories (2). The electric circuit is provided with a first self-holding relay (8) drivable directly by a relay drive signal outputted from the controller (6) and second self-holding relays (10,12) drivable in conjunction with the first relay (8). When a gate lock switch (5) is switched to a lock position while an engine is running, the controller (6) outputs an engine stop signal at a subsequent predetermined timing to stop the running of the engine, and also outputs the relay drive signal to drive the first relay (8) and the second relays (10,12) such that a key-on power supply and an accessory power supply are each held in a cut-off state.</p> |
