TIC LEXION 500 Electric System
03/05 Lex-e-26a 26a-3
Description of function:
Hydraulic oil level warning
(min.)
If the diesel engine is not started, the terminal (A30) recognizes an
earth signal on pin 15 as the signal of the float switch (Z19) and
displays the filling level alarm message. At the same time, the earth
signal is sent to the pulse generator K57 through the diode PCB (DI).
Low-pressure hydraulics/ground
drive oil pressure warning
If the diesel engine is started, the terminal (A30) recognizes an earth
signal on pin 15 as the signal of the oil pressure switch (Z46) and
displays the oil pressure alarm message. At the same time, the earth
signal is sent to the pulse generator K57 through the diode PCB (DI).
Hydraulic oil temperature
warning
The earth signal from the hydraulic oil temperature switch/sensor
(Z20/B123) is connected to terminal (A30) and displayed as an alarm
message (see Ground drive hydraulics metal detector warning).
Ground drive hydraulics metal
detector warning
Important: The ground drive hydraulics metal detector sensors
(B127) may be installed in parallel with the temperature
switch (Z20) (option). Consequently, the hydraulic oil
temperature warning may also be released by the
ground drive hydraulics metal detector sensors (B127).
Parking brake / brake lining
monitor warning
The earth signal of the parking brake switch (Z12) or brake lining
monitor (Z9a/b) is sent to the terminal (A30) and displayed as an
alarm message.
In the diagram, the state of the switch (Z12) is shown with the parking
brake applied.
Straw jam warning The earth signal of switch (Z61) is sent to the terminal (A30) and
displayed as an alarm message.
Half-tracks steering position
display
For machines with half-tracks, the connector X13 is connected with
the microswitches (Z38/Z39) on the steering axle.
Half-tracks tension If the oil pressure in one of the tensioning systems falls below
160 bar, the earth signal of the corresponding oil pressure switch
(Z36/Z37) is sent to the indicator light (H20) and at the same time to
the pulse generator via the diode PCB (DI).
Hydraulic filter warning The "Hydraulic filter plugged" alarm is released when switch (Z78) is
closed for more than 5 seconds (engine temperature > 60°C).
