functions.

units' functions
are activated.
Notes
Indicates lift arm at ground. Prevents unwanted down
tilting with hydraulic auto tilt.
Pressure guard for dropping pressure connected to
the tilt cyl side, sends (when in neutral mode)
connected signal (+) back to Di4, which in turn sends a
signal out (-) on Pa-, or provides Di4 with +signal from
a tilt sensor in the foot control unit cable set to indicate
'platform open'.
Pressure guard for rising pressure connected to tilt
cyl side sends (when activated) +signal back to
Di5 which blocks/cancels lift and tilt up functions.
No signal in on Cs results in blocked control unit con-
nectors. Signal to Cs usually comes from the cabin
switch, or in cases where such a switch is not used the
+signal comes in on Cs bridged from+ on the nearby
connector.
