What does Sirman carriage not engaged mean?

The VA 4000 control board has detected that the automatic carriage is not mechanically engaged with its drive system. The machine will not execute automatic slicing cycles until the carriage is properly coupled.

What does Sirman Fuse mean?

The VA 4000 display shows 'Fuse' when the protective fuse for the automatic carriage drive circuit has activated (tripped or blown). The control detects this loss of power to the carriage motor circuit and halts automatic operation.

What does Sirman Make service mean?

The VA 4000 internal slice counter has reached the 750,000-slice threshold programmed by Sirman as the general maintenance interval. The control displays 'Make service' to alert the operator and service technician that a comprehensive maintenance service is now due.
