Description of function:
Module A 20 actuates the corresponding solenoid coils Y 158 and Y159
for raising and lowering the chassis.
This is done automatically with the program "Approach working position /
Transport position" or using the "Manual operation" function.
Working position = chassis raised
Transport position = chassis lowered.
Secondary chassis raise When the turning area circuit is running, the Chassis raise solenoid coil
(Y158) is actuated for 2 seconds in parallel with lowering of the rotors.
This keeps the chassis from lowering when in the working position due to
a possible leak.
Chassis position The chassis position switch (Z99) transmits a signal to the electronic unit
when the chassis is raised.
If the chassis position is not detected in the "Approach working position"
and "Reset basic values" programs, the automatic functions are aborted.
Adjustment of sensors The chassis position switch (Z99) is set to a clearance of 4 mm from the
signal magnet with the chassis raised.
In this position, the signal magnet and the sensor should not be centred
opposite each other, but slightly offset.

TIC Liner 3000 with Communicator Electric System
Description of function:
To control the automatic functions, the electronic unit monitors:
- the drive speed
- the position of the rotor arms' hydraulic cylinders
Rotor position sensors B121 The rotor position sensors are integrated in the hydraulic cylinders as
contactless position measuring sensors.
A spindle with a steep thread inside the hydraulic cylinders rotates a
signal generator.
The angle of rotation between the retracted and the extended cylinder
position is < 360°.
The signal generator emits a magnetic field to the sensor electronic unit
located opposite of it. The position of the magnetic field which
corresponds to the hydraulic cylinder position is detected by the sensor
electronic unit.
The sensor electronic unit transmits a pulse-width modulated signal
(PWM, corresponding to the hydraulic cylinder position) to module A 20.
With the hydraulic cylinder retracted, this signal is 5% and with the
cylinder extended, it is 95% PWM.
See also the Technical Systems / Hydraulic system documentation.
Offset of rotor position
sensors B 121
The position "Hydraulic cylinder retracted" must be programmed in the
sensor electronic unit (= sensor offset).
This programming changes when the ram rod of a hydraulic cylinder is
rotated, e.g. during service work.
For offset programming, the sensor signal output must be connected to
the 12 V sensor supply voltage for at least 2 seconds.
The CCU module carries out this offset programming during each basic
initialisation. This is done by the diode component D.1-4 and amplifier
V16-2.
This is detected at terminal A30. When the basic initialisation is carried
out, a cylinder position of 100% and then of 5% is displayed for a short
time when in transport position (cylinder retracted).
When a hydraulic cylinder position which is illogical to the electronic unit is
detected, e.g. due to service work, an error is reported.
In order to remove the error, the operator may move to transport position
or carry out a basic initialisation.
The PWM signal from sensors B121 is also displayed as cylinder position
on terminal A30. This involves slight deviations:
90% signal change = 100% change of display on terminal A30.
Approach transport position
program
If the drive sensor B9 detects a signal change (universal drive shaft is
rotating), approaching the transport position in automatic mode is not
possible.
Adjustment of
drive sensor B9
Sensor B9 is set to a clearance of 3-4 mm from the outside profile of the
drive shaft.

Description of function:
No volume flow is flowing The pressure spring pushes the control piston of the input pressure
balance (763) to its stop. The connection from P to T is closed.
Volume flow is flowing – no
solenoid valve is actuated
One solenoid valve is
actuated
Volume flow is supplied via channel P and flows to each of the
downstream control units.
Since no solenoid valve has been actuated, each spool blocks the volume
flow.
This builds up pressure which acts on the left-hand end of the input
pressure balance (763) control piston and pushes it against the pressure
spring.
This opens the connection from P to T. At the same time, a partial volume
flow flows via the orifice plate (in the control piston) into the spring space
of the control piston.
The spring space is not pressurized since it is connected to the channel
(LS).
A fixed pressure difference is established at the control piston.
When a downstream solenoid valve is actuated, volume flow flows via
channel P and the spool into the cylinder(s).
The load pressure built up now is directed into the spring space of the
input pressure balance (763) control piston via the LS channel.
The pressure build-up controls the control piston so that the connection
from P to T is partly closed.
This closing is necessary to make volume flow available for actuating the
cylinder(s).
However, the control piston is displaced to the left only until the fixed
pressure difference is re-established.
A partial volume flow will continue to flow into the tank.
When the cylinders are at their stop position, the pressure rises and is
available in the spring space of the input pressure balance (763) control
piston via the LS channel and presses the control piston to its stop. The
pressure in channel P opens the pressure control valve (706).

Example:
Solenoid valve (Y162) is

Control behaviour of the
flow controller
Due to the two face-end pressure springs, the spool is positioned so that
the ports P and the consumer ports are blocked (see diagram).
The volume flow enters the control unit via channel P. It flows to the spool
through the orifice plate of flow controller (767-4).
Since the spool prevents continued flow, a pressure is built up which acts
on the right-hand face end of flow controller (767-4) and also in the spring
space. Now equal forces act on the flow controller (767-4) and the
pressure spring pushes it to its stop position.
The solenoid coil (Y162) actuates the spool to the left against the
pressure spring.
The connection from the pump (P) to the left-hand consumer port and the
connection of the right-hand consumer port to the tank (T) are opened.
In this position, the flow controller (767-4) controls the volume flow to
20l/min ± 0.5 l. This happens even when the load pressure of the
consumer changes.
When volume flow flows through the flow controller (767-4), different
pressures result:
- The pump pressure acts upstream of the orifice plate (3a)
- The load pressure acts downstream of the orifice plate (3a)
Since the pressure downstream of the orifice plate is lower than the
pressure upstream of the orifice plate, a pressure difference results.
The flow controller keeps this pressure difference constant even when the
load pressure of the consumer (in the spring space) changes.
t a constant pressure difference, the volume flow to the consumer is also
constant.

Due to the two face-end pressure springs, the spool is positioned so that

The volume flow enters the control unit via channel P.

Since the spool prevents continued flow, a pressure is built up which acts

Now equal forces act on the flow controller (767-2. -3) and the pressure
spring pushes it to its stop position.

This opens the connection from the pump (P) to the consumer port.
In this position, the flow controller (767-4) controls the volume flow to
10l/min ± 1 l. This happens even when the load pressure of the consumer
changes.
When volume flow flows through the flow controller (767-2. -3), different
pressures result:
- The pump pressure acts upstream of the orifice plate (3a)
- The load pressure acts downstream of the orifice plate (3a)
Since the pressure downstream of the orifice plate is lower than the
pressure upstream of the orifice plate, a pressure difference results.
The flow controller keeps this pressure difference constant even when the
load pressure of the consumer (in the spring space) changes.
At a constant pressure difference, the volume flow to the consumer is also
constant.

The active solenoid coil (Y159) actuates the spool to the right against the

Volume flow flows from channel (P) via the spool to the closed consumer
