Event: 14. Fork tilt, backwards/upwards
Previous event 3. Basic control criteria.
Action(s) The control for the fork lift [B22] is moved towards the operator and
input A1-X505:17 is reduced from approximately 2.6 V to approxi
-
mately 0.6 V at the end position of the control.
Contributing factors –
Resulting conditions The pump motor is supplied with three-phase voltage from the transis-
tor regulator [T2].
Output A5-X131:37 “OUT.AUX DIRECTION A” reduces the voltage.
Output A5-X131:11 “OUT.AUX DIRECTION B” remains high.
Current flows through the coil [Q8].
The tilt cylinder is pressurised via the non-return valve.
On sideshift, or some other optional function: the following also applies:
Output A5-X131:38 “OUT.TILT/SIDESHIFT/AUX 1” remains high.
No current flows through the coil [Q18].
Event: 15. Fork tilt, backwards
Previous event 3. Basic control criteria.
Action(s) The control for fork lift [B22] is moved away from the operator, and
input A1-X505:17 increases from approximately 2.6 V to approximately
4.7 V at the end position of the control.
Contributing factors –
Resulting conditions Output A5-X131:37 “OUT.AUX DIRECTION A” remains high.
Output A5-X131:11 “OUT.AUX DIRECTION B” reduces the voltage.
Current flows through the coil [Q9].
The tilt cylinder is drained to the tank.
On sideshift, or some other optional function: the following also applies:
Output A5-X131:38 “OUT.TILT/SIDESHIFT/AUX 1” remains high.
No current flows through the coil [Q18].
