1. General information

1.1 Rights to changesWe try to ensure that these operationg instructions are correct and up to date. In order to

maintain our technical leadership, however, it might be necessary, without prior warning, to

make changes to the product and to its operation which, under circumstances, do not

correspond to the information given here. We accept no liability for disturbances, losses or

damages caused thereby.

1.2 Packaging and storageThe product is carefully packed to ensure sufficient protection during shipment. On receipt the

packaging and the contents should be inspected for possible damage.

Should there be signs of damage the equipment must not be operated !!!

Damaged cables and connectors are also a safety risk and must not be used !!!

Intheeventofdamagecontac ABG.

The equipment must be protected against humidity and dirt if it is not to be used immediately.

1.3 Safety measuresWarning:

Before assembly, setting up and operating the equipment read the operating instructions

carefullyandfully. Should questions arise, contact your ABG supplier.

Safety precautions:

Thesafetyprecautionsrecommended herecorrespondto basicregulationsregardingoperation

of electrical systems. They can be applied for all applications in conjunction with ABG

equipment.

Assembly:

OnlyoriginalABGcablesmaybeused.Plugsandsocketsmustnotberemovedfromthecable

that the safety screw fasteners sit securely on the connectors . Further information about the

assemblyofthe equipment, and the sensors,can befound inthe data sheetsattachedor inthese

operating instructions.

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

not be exceeded.


7/44

Page 5

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.

4.3 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.
