Functional description
21.4.10 Maximum height
Truck with pulse counter.
Once the forks reach the main lifting range, A5 receives information
from switch S45 to begin counting the pulses from sensor U10. The
forks stop when the pre-programmed maximum heights (there are two)
have been reached. If the forks are to be lifted above these heights,
switch S33 must be depressed, which sends a signal to A5 and move
-
ment continues. Start must occur within fifteen seconds.
LEDs 301, 302 and 303 light up depending on whether the respective
sensors are actuated or not.
21.4.11 Fork lowering
When the driver actuates the hydraulic lever R11, a voltage of 3.7-0.66
V is fed to A5, which opens the proportional valve Y10 and Valve Y45,
and the driver can lower the forks at variable speed.
If the truck is equipped with a pulse counter, the lowering speed is
reduced at the transition from main lift to free lift. The LEDs shine dimly
in the neutral position and brightly when lowering begins.
Without a pulse sensor, the lowering speed is reduced when switch
S46 is actuated.
