TROUBLE SHOOTING

Error messages

There are two types of error messages that can appear on the display:

•Service messages - These messages do not represent any direct danger for the operator or the machine.

•Warnings - These warn of faults or safety defects that can cause mechanical damage.

All error messages that have been acknowledged re- main as small yellow red warning triangles in the Þeld for service and can be accessed by bringing up the service menu and selecting ’Warnings”. The messages are listed in order of priority, highest priority Þrst.

When a fault that has in some way restricted the ma- chine’s functions ceases, a message appears on the display. This message must be acknowledged for the machine to return to full functionality.

Service messages

When a service message appears on the display, the operator is made aware of it through the work light ßashing three times.

The service message remains on the display until the operator has acknowledged it. The message disap- pears from the display and is replaced by a yellow warning triangle in the Þeld for service. The triangle symbol remains for as long as the message is current.
