TIC LEXION Montana 570-520 Electric System
03/05 Lex-e-26t 26t-3
Description of function:
Hydraulic oil level warning (min.) If the diesel engine is not started, the terminal (A30) recognizes an
earth signal from the hydraulic oil level float switch (Z19) on pin 15
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 from the oil pressure switch (Z46) on pin 15 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). Thus the hydraulic oil temperature
warning can also be released by the ground drive
hydraulics metal detector sensors (B127).
Montana brake oil pressure
warning
At a pressure below 115 bar, the voltage signal from the left / right
brake circuit pressure switches (Z79/Z80) is connected to the terminal
(A30) and displayed as an alarm message.
Reloading the brake circuit is controlled via the brake circuit charge
pressure sensor (B90) – see circuit diagram 41t.
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
On machines equipped with half-tracks, connector X13 is connected
with the microswitches (Z38/Z39) on the rear axle.
Hydraulic filter warning The "Hydraulic filter plugged" alarm is released when switch (Z78) is
closed for more than 5 seconds (engine temperature > 60°C).
Service brake Pressing both brake pedals (Z84/Z85) is a pre-condition for shifting
the gears in the manual gearbox.
To guarantee that the machine is standing still, a brake pressure of
25 bar min. must be built up by the force acting on the pedal.
At the same time, the control oil pressure necessary for the ground
drive is relieved – see circuit diagram 41t.
Parking brake When actuating the parking brake (S93), the control oil pressure
necessary for the ground drive is relieved – see circuit diagram 41t.
