Functional description
21.4.2 Truck started up
Truck power is switched on when the driver logs in using his code and
presses the green button I on the keyboard. In order to use the travel
direction selector and hydraulics, the driver must sit in the truck so that
switch S89 is on. The voltage is fed through the control fuse F60, the
keyboard relay and the emergency switch S21 to the electronic card
A5, frequency converters A1 and A2, height electronics A7 and A8, and
the fan M10, which starts. The A5 electronic card checks that the inter
-
nal safety function is functioning and closes the main contactor K10,
which provides power to the drive and pump motors. The A5 electronic
card starts communications with the height electronics A7 and A8, and
provides +32 V to the fan M12, which begins to rotate at half-speed.
A5 checks that the voltage from the potentiometers is +3.65 V and
sends control pulses to tachometer U1 and steering motor M6. If the
seat has built-in heating, a voltage of +48 V is also supplied to the ther
-
mostat and the seat heater E10.
The display turns on and the computer software version number is
shown before the display switches to normal mode: time of day, operat
-
ing time, battery status, load weight and any error codes.
The length of time that the truck is in use is monitored and stored in the
electronic module.
The LEDs in the following table will light up:
• No. 706–711 light up if the valves are not installed on the truck.
• No 110, 203 and 305 light up if the switches are actuated.
The LEDs on the frequency converters light up.
