Three control units belong to the crane control: If one control unit fails, theCrane control displaydisplays an error message as in the diagram opposite:
SYSTEM is in the second line. In the third line you will find UNIT 0, 1 or 2, for the control units on the connections 0 to 2.
The number code in the fourth line is of secondary importance.
The following table shows which crane functions are out of operation when the control unit fails on a connection:
Error message on the display

connection 0 defective, function of the crane control, main hoist and auxiliary hoist blocked.
The truck crane can be rigged by changing the connection lines on another control unit in on-the-road mode;

If there is an error message about drive units it will appear in the second line of the affec-ted drive unit (e. g. the telescoping gear).
You also get different entries and number codes in the two bottom lines.

If you have already acknowledged the error message, you can call up the Display statesmenu and then>
thememory error submenu and view the error message there again;➠
Display states menu - Memory error submenu, p. 13-82.In the first line you will see the message ERROR MEMORY and the number of the error (e. g. 3). The displays in the other lines are the same as with the error message.
The messages here are only an example which will be dealt with at the end of the following sections.
Using the messages in the bottom two lines you can
– determine the part on which the error occurred;
➠
Determining defective part, p. 16-61.– determine the area of the error, depending on the detected part;
➠
Determining error area, p. 16-62.– locate more precisely the cause of the error;

In the following sections you will find more information on the displayed errors. If, in the sections, you are asked to contact GROVE Product Sup-port, please note down the number code beforehand and have it ready.Ö
When you have noted down the error codes you can acknowledge the error message. To do this press theENTERkey.After you have carried out the acknowledgement process, the display shows the indication which was displayed before the error message.

In the display used as an example the number code 0 0 0 0 0 0 0 1 is in the last line.
The table assigns this number code an error in the output area.
The “output” area is in the table in the next section. Here you can determine the cause of the error in this area.

Once you have determined the defective part or the area where the error is, the table will give you more information on the cause and the effects.
In this table the number code in the third line behind the part (e. g. 0 0 0 0 0 0 0 1 behind Y 2301) is decisive.

Example
In the display used as an example the number code 0 0 0 0 0 0 0 1 is in the third line.
In the previous section we determined that the er-ror was in the output area.
According to the table this number code means that there is a Line breakage or a 24V short.
In this case you must inform GROVE Product Support and have the supply line checked.
