4. Design and function
The LGC2-A and LCG2-B curve sensor control
units are used to control wheel flange and
railhead lubrication systems. In these systems,
the lubricant is sprayed through spray nozzles
onto the wheel flange of the rail vehicle or
onto the head of the rail. The term "spraying"
is therefore used in the description below.
As can be seen from the control units' electri-
cal connection diagrams, the compressed air
valves Y1 and Y2 are always connected via
outputs A1 and A2. Where appropriate for
clarity, the following description only mentions
the corresponding valve, Y1 or Y2.
Additionally, for the sake of clarity the follow-
ing text only indicates the software version
numbers 01, 02, and 03 from the device or-
der code (e.g., LCG2-Axx-XXX+924 or LCG2-
Bxx-XXX+902) because the corresponding
functions of the LCG2-A and LCG2-B series
are identical.
4.1 Design
The significant differences between the
LCG2-A and LCG2-B series are in their hous-
ing dimensions, their design, and their operat-
ing voltage. Both series are available with
software versions 01, 02, or 03.

4. Design and function
4.2.1 Curve sensor special mode
DIP switch 2
= OFF: Curve sensor control function
(factory setting)
DIP switch 2
= ON: Curve sensor special mode
After switching to the curve sensor's special
mode, the device functions as a "pure" curve
sensor in that a continuous signal instead of a
spray cycle signal is issued on the respective
valve output (A1 or A2) as long as a curve is
being traveled and the preset curve signal
threshold is exceeded (for the sensitivity set-
ting, see Table "D" for the respective software
version (01, 02, or 03) as well as operating
mode "Curve-dependent spraying").
No further enabling signal is required to issue
the continuous signal. This function is, how-
ever, only intended for an application in which
all other functions are handled by another
control unit, for example a stored-program
controller (SPC) already installed in the vehi-
cle, or the SKF IG665+924 control unit (only
available in 24 V DC), which comes with addi-
tional functions beyond the control unit mod-
els described here, such as compressor control
for compressed air generation (control and
monitoring), lubricant monitoring (fill level and
pressure), special lubricant pump control, etc.
The DK pushbutton and the FG, VR, DK,
and +P/-P control inputs, as well as DIP
switches 1 and 3 to 8, have no function
in the curve sensor's special mode.
The setting for DIP switch 2 is read and
processed by the control unit only after
a program restart.

EN 4. Design and function
The curve sensor control units feature an in-
ternal sensor that directly detects the turning
motion of the rail vehicle as it travels through
a curve. The control unit evaluates the sensor
signal; if an adjustable signal threshold is ex-
ceeded and the spray enable conditions are
met, a spray cycle is triggered via the corre-
sponding spray valve (Y1 or Y2). The spray
valve cycles when there is an extended-dura-
tion curve signal (see adjustable spray interval
time in 4.2.5 and spray time in 4.2.9).
Spray enable condition when using curve-de-
pendent spraying:
• Enable input FG connected
(switching contact FG closed)
Spray enable condition when using curve- and
time-dependent spraying:
• Enable input FG connected
(switching contact FG closed)
Spray enable conditions when using curve-
and distance-dependent spraying:
• Enable input FG connected
(switching contact FG closed)
and
• Pulse frequency at input +P/-P is
greater than 3.5 Hz (minimum travel speed
has been reached)
If only curve-dependent spraying is to be per-
formed, the setting for DIP switch 1 must also
be considered (see Spray enable conditions in
4.2.6).
The curve sensor function is activated (switch
settings 1 to F) and deactivated (switch setting
0, factory setting) on the rotary switch.
The sensitivity of the curve sensor can be set
(in angular degrees per second) using switch
settings 1 to F as shown in the "D" tables in
Chapter 6 for the respective software version
(01, 02, or 03) as well as operating mode
"Curve-dependent spraying."
If a time- or distance-dependent spray cycle is
ongoing when a curve is detected, the spray
cycle continues until completion. The curve-
dependent spray cycle is eliminated or
overridden.
Each time the operating voltage is switched
on, a waiting period of 6 seconds is required
for the automatic "curve zeroing" before the
vehicle is moved.
Based on the type of curve sensor
employed, the curve sensor control de-

A microcontroller generates a moving

4. Design and function
4.2.3 Curve-dependent spraying,
outside curve
(software version 01)
In software version 01, only the spray nozzle
(left or right) outside the curve is actuated
during curve-dependent spraying. Each of the
two spray nozzles is activated via a separate
valve, Y1 or Y2. If the vehicle is operated in
two directions, direction of travel input VR on
the control unit must be connected (switching
contact VR closed) when the vehicle moves in
direction of travel 2 so that the spray nozzle
outside the curve can be actuated in this situ-
ation (see Curve function, Fig. 5).
4.2.4 Curve-dependent spraying,
both sides
(software versions 02 and 03)
In software versions 02 and 03, only valve Y1
is actuated during curve-dependent spraying
in both curve directions; the valve then acti-
vates both spray nozzles (left and right). If the
vehicle is operated in two directions, direction
of travel input VR on the control unit does not
necessarily need to be connected when the
vehicle moves in direction of travel 2. If, how-
ever, spray nozzles on the other end of the
vehicle are to be actuated, all spray cycles can
be directed to valve Y2 by connecting direction
of travel input VR (switching contact VR closed)
(see Curve function, Fig. 5).
4.2.5 Setting spray interval time tPfor
curve-dependent spraying
(software versions 01 and 02)
The spray interval time tP for curve-dependent
spraying is set using DIP switches 3 and 4 (see
Table B on page 42).
(software version 03)
The spray interval time tP for curve-dependent
spraying is set using DIP switch 4 (see Table B
on page 47).
Note
Setting the curve-dependent spray interval
time tP also defines the following times:
In software versions 01, 02, 03:
Minimum possible interval time for dis-
tance-dependent spraying if, for example,
an excessively low number of pulses was
preselected for the cycle duration.
Only in software version 01:
Spray interval time tP when using time- or
distance-dependent spraying between spray
times tS of valves Y1 and Y2, which are ac-
tuated sequentially in this operating mode.

4.2.6 Time- or distance-dependent spraying
The operating modes and all other functional
parameters are set using DIP switches 1 to 8
in accordance with the corresponding tables in
Chapter 6 of these operating instructions.
DIP switch 1 defines a preselection for the fol-
lowing operating modes:
DIP switch 1
= OFF: Time-dependent spraying
(factory setting)
DIP switch 1
= ON: Distance-dependent spraying
The preselected operating mode is only effec-
tively activated once at least one of the DIP
switches from 5 to 8 is switched to the ON
position.
If only curve-dependent spraying is to be per-
formed, DIP switches 5 to 8 remain in the OFF
position (factory setting).
Spray enable conditions
Setting DIP switch 1 also defines the spray
enable conditions irrespective of whether the
preselected operating mode is activated using
DIP switches 5 to 8:
DIP switch 1
= OFF: Spray enable only via input FG
(factory setting)
DIP switch 1
= ON: Spray enable via input FG and
minimum pulse frequency on input
+P/-P
Spray cycle triggering in software version 01
A time- or distance-dependent spray cycle is
performed in the sequence:
Spray time tS for valve Y1 - spray interval time
tP - spray time tS for valve Y2 – spray interval
time ≥ tP.
Spray cycle triggering in software versions
02 and 03
A time- or distance-dependent spray cycle is
triggered based on the connection of direction
of travel input VR:
Switching contact VR = open:
Spray time tS for valve Y1 – spray interval
time ≥ tP
Switching contact VR = closed:
Spray time tS for valve Y2 – spray interval
time ≥ tP
