(c) There are three modes, which are respectively: The message of mode selection " ", " "
and " " will be sent to the controller through the CAN.
(d) When the sign " " indicates the moving forward, the high level triggers: when the sign " "
indicates the moving backward, the high level triggers: the sign " " represents the parking brake, the
high level triggers: when the sign represents the lifting lockup, the instrument control: when the sign
" " represents the maintenance of vehicle, the instrument controls:
(e) The hour meter, clock and maintenance hour meter: (f) LED flashing alarm:
4.6.4.4 Instructions for use
a) Turn on the key switch, the power supply 12V will feed the instrument, at the meantime the PS 48V will
be added on the instrument and electric control loop through the starter relay in the relay box. On gauge,
the LC instrument shows the vehicle information "TRAVEL" and "HYD", on the right side, displays
"OK", that means that the control device is in normal working state.
b) The hand brake is displayed when the brake is applied. On the gauge, the indication " " will show up:
when the hand brake is released, the indication will go off.
c) Travel direction display
When the direction switch is placed in N-gear, no direction is displayed on the instrument: when the
forward gear is shifted, the indication " " is shown and the backward gear engaged, the indication
" " displayed with the beeps of back-up buzzer.
d) Battery capacity display
After the instrument is turned on, the battery voltameter will show the class of current battery power. The
voltameter can display in total 10 cross-bars and 10 grades of capacity. The battery voltage range is
between 41. 5V～56V. The top one is lightened. It means the battery power is full. When two lowest bars
flash alternatively, it means that the battery is short of power and must be charged at once. Once the cross-
bar in display is lowered one scale, it means that the capacitance is reduced about 8%.
e) Low limit alarm of battery capacity
When the voltameter shows the last two cross-bars, the battery power has reached the lower limit. Now the
sign "！" is shown at the right side of the instrument The indicator light turns yellow and flashes over at
the meantime. When the voltameter shows the last cross-bar, the sign "！" will be shown at the right side
of instrument. The indicator light turns red and flashes over at the meantime. At the meantime, the
protection relay of lifting power supply loop moves in action. The protection relay has two motion: When
