Wiring and cabling:
The wiring and cabling must be correctly carried out in accordance with these instructions. All
supply cables and terminals must be sized according to the current taken. Further, all
connections must be made in accordance with VDE regulations or regulations of the area in
which the equipment is used.
Safety in the event of disturbances:
This equipment has been developed and tested for industrial environments. Nevertheless,
microprocessor technology requirescareful installation. We would therefore liketo pointout thefollowing which, if not heeded to, can lead to disturbances during the operation later:
- Pay attention to the correct polarity of the connections
- Donotexceed (neithertoohigh nor too low)thespecifiedvoltagesupply range
- Protect the equipment with a suitable supply fuse
- Use cables of adequate current and voltage ratings
- Use the shortest possible cable paths. (Avoid loops)
- Lay out load, control and signal cables in separate channels where possible
- Suppress contactor and relay coils
- Prerequisitefor a disturbingsure modeis a goodelectrical connectionbetween
the machine chassis and housing chassis of the units.
- Connect screened leads to earth at one end only (equipment end)
- Do not supply other equipment directly from the supply terminals
- Do not use unused terminals as connections for other equipment
Maximum voltages:
Donotexceedthemaximumvoltages.Themaximumvoltagebetweenanytwocircuitsisolated
from one another, or between any isolated circuit and earth is, unless otherwise stated, limited
to its highest input voltage or the supply voltage. The connecting terminals or connectors must
be fitted with a suitable fuse.
Fuses:
The equipment is fitted with electronic fuses which protect it against wrong polarity, voltage
transients and overvoltages of short duration. The voltages specified in the technical data may

Configuration:
The equipment can be configured by the user. It is the responsibility of the user to reconfigure
according to the operating conditions of the system.
Alarm supervision
In complex systems, in which a fault could endanger operating personnel or damage to the
system, it is advisable, to use an independent alarm unit. An independent alarm unit provides
protection and shut-down of the system in the event of an alarm. In many cases the use of an
alarm from withinthe controller itself does not, becauseof its dependence on thesystem, offer adequate protection.
Explosive areas
The equipment is not designed for use in explosive areas.
Fault clearance
Before starting to clear faults make sure that all voltages have been disconnected. Defective
equipment should be tested in an area which has been especially built for this purpose. Any
attempt to remove faults from equipment that is still installed can be dangerous to personnel
and to the system itself. Before removing or replacing sensors make sure that the voltage
supply has been disconnected.
Ask for help
Ask your ABG supplier if you have questions concerning the operation and assembly of the
equipment.
Failure to observe the above safety measures can cause breakdown of the equipment
or of the system. Damages caused by such negligence are not covered by the
manufacturer's guarantee.

4.2 The Handset
The Handset is used to set the required cross
slopeinpercentage,onetenthofapercentage
and one hundredth of a percentage. The
Handset has a LC-Display. The cross slope
can be adjusted up to 15 % to one or to the
othersidebymeansoftheUPorDOWNkeys.
If you press the FAST key additional the
speed of adjusting will increase.
Pressing the RESET key and keeping it
pressed shows the symbol of the UP andDOWN arrows which are flashing. After 4
seconds the arrow symbols are on. Pressing
the UP or DOWN key additional changes the
display value without influenceto the setpoint.
This way of proceeding is important for the
zero setting of the controller. The Handset of the S 276 M

4.3 Zero setting
If the level controller is mounted, if the valve switch is positioned to “STANDBY” and if the
c on ne ct i ng c ab le i s a t ta ch ed , t he c on tr o ll er s ho ul d b e a dj us te d t o “ z er o ”.
The following procedure is recommanded for the zero setting only.
1. Put the actuator (the screed in case of the finisher) to zero by means of an accurate water
level.
2. Switchon the power supply of the machine in order to supplyvoltage to the level controller.3. Set the sensitivity adjuster to the middle position.
4. Cange the setpoint by the means of the UP or DOWN key until both lamps are off.
5. Pressing the RESET key and keeping it pressed shows the symbol of the UP and DOWN
arrows which are flashing. After 4 seconds the arrow symbols are on. Press know the UP
or DOWN key additional and change the display value to the value 0.00.
Note:
Should one of the two control lamps be on or flash after this setting, you must repeat the steps
4 and 5.

4.5 Setting of the crosse slope and start-up
Adjust the required cross slope to the left or to the right by by the means of the UP or DOWN on
the Handset. The counter indicates the cross slope ajusted.
The control lamps indicate the functioning of the controller. In case of a deviation between theSetpoint and the actuel slope the lamps are switched on and indicate the direction of travel. If
both lamps are out, the slope is in the required position.
If the slope controller has to beeffective on the
left side of the machine, seen in the direction
of travel, the selector must be switched to the
position “L” for left. If the slope controller has
tobeeffectiveontherightsideofthemachine,
seen in the direction of travel, the selector
must be switched to the position “R” for right.
The connecting cable must be attached to the
corresponding side of the machine.
Turning the valve switch to the position “ON”
connects the output of the controller with the
according valve. The automatic system is
activated.
Note:
A clockwise ro ta ti on of the sensit iv ity
adjustment increases the sensitivity of the
controller. A counterclockwise rotation
decreases the sensitivity.
Turn the sensitivity button clockwise until the
hydraulic system starts to swing. When this is
t he c ase , t ur n t he a dj us ter s lo wl ycounterclockwise until the hydraulic system
quiets down.
A minor readjustment of the device may be
necessary after the first operation of the plant
becausevibrations,temperaturesetc.influence
the control circuit. No further adjustment
should be needed if the readjustment had
been done under working conditions.

5. Maintenance
5.1 General information
Thelevel controller hasbeen designed for high working safety so that themaintenance needs a
minimumofproceduresonly.
The electronic components are mounted in a solid case in order to avoid any mechanical
damage.
5.2 Periodic maintenance
Normal repair procedures carried out in the open consist in replacing burned-out lamps and
other spare parts that have been located with the troubleshooting. The power supply cables
should also be checked regularly in order to detect any damage and dirt.
Note:
Keep the thread of the plug-connections and of the cable connectors free of any dirt, grease,
asphalt or concrete in order to avoid a bad contact. Remove any asphalt or concrete sticking
to the sensor arm by means of an appropriate agent and oil the bearing afterwards.
