Functional description
21.4.12 Mast out/in
When the driver actuates the hydraulic lever R12, voltage (out = 3.7-
0.77
V or in =3.7-6.6 V) is fed to A5, which opens the direction valves
Y12/Y13 and sends a signal to the frequency inverter A2. Pump motor
M3 starts and pumps oil to the reach cylinder. Before the mast reaches
the end positions, pump motor speed is reduced.
21.4.13 Fork tilt up/down
When the driver actuates the hydraulic lever R13, voltage (up = 3.7-
6.6
V or in =3.7-0.66 V) is fed to A5, which opens the direction valves
Y14/Y15 and sends a signal to the frequency inverter A2. Pump motor
M3 starts and pumps oil to the tilt cylinder.
21.4.14 Hydraulic function 4
When the driver actuates the hydraulic lever R14, voltage (3.7-6.7 V or
3.7-0.66
V) is fed to A5, which opens the direction valves Y16/Y17 and
sends a signal to the frequency inverter A2. Pump motor M3 starts and
pumps oil to the extra function.
