6.11. THE LCD SHOWS “WARNING: CHECK BATTERY”
The machine displays this error message on power up whenever it finds inconsistent data in the
battery-backed memory. In consequence:
• It is normal for the machine to show this message on the first power up after replacing the
display;
• It indicates a problem if the message appears at other times.
The cause of the problem may be:
• Defective battery that fails to charge to 3.6 Vdc;
• The CPU board fails to recharge the battery (see voltage on pins 1 and 2 of connector CN5 on
the CPU board).
6.12. THE LCD SHOWS “BELT LUBRICANT OUT: REFILL”
WARNING: Old SW version shows “BELT LUBRICANT OUT, ACT NOW” instead of
this message.
The machine displays this message when the oil level in the reservoir has reached the minimum
mark.
WARNING: This message is ambiguous and may be misinterpreted. In fact it does not
mean that the oil is completely out, but only that its level is low. Under these conditions
the lubrication can continue to operate for at least another 2-3 cycles.
If this message appears even though the oil level is above the minimum mark, the oil-low sensor is
probably damaged and it is necessary to replace the pump.
If a machine not provided with the automatic lubrication system shows this error, the
short between pins 9 and 11 of the patch connector CN4 can be opened.
