1.2 CORTO 8100 F electric system
1.2.1 Putting into
operation
Switch on stop switch 1. Current is applied to the relays, terminal 86 and
the solenoid valves.
1.2.2 Switching on the
right-hand drive
Actuate rocker switch 3.
Earth is connected to relay 17 on terminal 85 and to solenoid valve 70.
Relay 17 connects earth to relay 15 and to the 4/3 way solenoid valve
50B.
Relay 15 cuts the current supply to the lock-up valve units 89 and 99.
Via the 2/2 way solenoid valve and the 4/3 way solenoid valve, oil flows
into hydraulic cylinder 77. The right-hand drive is now switched on.
1.2.3 Shutting down the
right-hand drive
Actuate rocker switch 3.
Earth is connected to relay 16 on terminal 85 and to solenoid valve 70.
Relay 16 connects earth to relay 15 and to the 4/3 way solenoid valve
50A.
Relay 15 cuts the current supply to the lock-up valve units 89 and 99.
Via the 2/2 way solenoid valve and the 4/3 way solenoid valve, oil flows
out of hydraulic cylinder 77 – the drive has been shut down.
1.2.4 Switching on the
left-hand drive
Actuate rocker switch 2.
Earth is connected to relay 17 on terminal 85 and to solenoid valve 71.
Relay 17 connects earth to relay 15 and to the 4/3 way solenoid valve
50B.
Relay 15 cuts the current supply to the lock-up valve units 89 and 99. Via
the 2/2 way solenoid valve and the 4/3 way solenoid valve, oil flows into
the hydraulic cylinders 78 – the drive is now switched on.
1.2.5 Shutting down the
left-hand drive
Actuate rocker switch 2.
Earth is also connected to relay 16 on terminal 85 and to solenoid valve
71.
Relay 16 connects earth to relay 15 and to the 4/3 way solenoid valve
50A.
Relay 15 cuts the current supply to the lock-up valve units 89 and 99. Via
the 2/2 way solenoid valve and the 4/3 way solenoid valve, oil flows out of
hydraulic cylinder 78 – the drive is shut down.
1.2.6 Raising the left
CORTO
Actuate rocker switch 5.
Earth is connected to relay 17 on terminal 85 and to solenoid valve 75.
Relay 17 connects earth to relay 15 and to the 4/3 way solenoid valve
50B.
Relay 15 cuts the current supply to the lock-up valve units 89 and 99. Via
the 2/2 way solenoid valve and the 4/3 way solenoid valve, oil flows into
hydraulic cylinder 100 – the left mower unit is raised.
