Before connecting the equipment to the supply voltage, read the following Safety

Guidelines, in order to protect yourself and the equipment from any serious

danger.

• Read all the instructions for the installation, before connecting the supply

voltage and alarm cable.

• Follow all the instructions and precautions concerning the equipment.

Immediately disconnect the supply voltage and alarm cable in the following cases:

• If the connecting cables or the connectors are worn out or damaged.

• If liquid is present, even in the form of moisture, inside the equipment.

• If the case of the equipment shows damage or breaks.

• If it is felt that the equipment requires maintenance or repair.

tWarning: before cleaning the mixer wagon with high pressure jets of water,

disconnect the connection cables, remove the equipment from the mixer

wagon and protect the connectors of the connection cables from water

infiltration. Also take great care to see that the load cells, junction box, alarm

device and other options are not exposed to direct jets of water. y

tWarning: before carrying out welding operations on the mixer wagon, always

disconnect the connection cables. In order to prevent the welding current

from passing through the load cells, it is necessary to short circuit the body of

the load cells with a cable having a suitable cross section, besides positioning

the pliers of mass as close as possible to the welding point. y

tWarning: if, during the operation, the display shows the blinking symbol b

or the writings [ LOWBAT ] or [ H.BAT ] or [ OV.LOAD ] or [ ERR-xx ], refer to

the Appendix A - Error Codes. y

1General Information

The equipment follows Technical Procedures that allow to program different

Preferences, to meet the real requirements by the user in the best way.

For this reason it is recommended, when installing the equipment, to program the

TEST 1 - DISPLAY

The Test 1 checks the correct operation of the equipment display and of the

displays of possible connected Remote Terminals. The equipment switch on all the

segments and available symbols in sequence, and then switching them on

altogether.

To exit the Test press the key Menu.

TEST 2 - A/D CONVERTER

The Test 2 checks the correct operation of the A/D Converter.

The equipment reads and directly shows on the display the value supplied by the

A/D Converter and relevant to the signal coming from the load cells.

The letter on the left of the display (A, B, C, D), indicates the reference voltage

(5mV, 10mV, 20mV, 40mV) used by the A/D Converter, that can be selected using

the keys qor z. To exit the Test press the key Menu.

rCaution: if the displayed value of the A/D Converter is not stable, or if the

display shows the error [ ERR- 1 ], this means there is a fault.

Refer to Appendix C - Troubleshooting or apply to the Technical Service and

Support. r
