Method for delivering electric power to power consumers of a printing technology machine

摘要

A method for delivering electric power to power consumers of a printing technology machine, which permits high availability of the machine with low idling losses, includes taking start-up time periods of the power consumers into account when switching over the power delivery to power consumers of a printing machine.

1. A method for delivering electric power to power consumers of a printing technology machine, the method comprising the following steps:
switching over power delivery between a working operation and a standby operation; providing actuating signals as a function of a time behavior to a circuit configuration for power supply to groups of power consumers operated in different circuits; providing the groups of power consumers with different start-up time periods to reach the working operation after the standby operation; assigning each of the groups of power consumers to an inactivity time interval; upon the machine being inactive after carrying out a machine operation in the working operation, shutting down the power delivery beginning with a group of power consumers having a lowest start-up time period and continuing successively with further groups of power consumers having increasing start-up time periods, with ongoing inactivity and following expiration of a respective inactivity time interval; and maintaining the power delivery to a computer controlling the machine in the working operation, after the power delivery to a last group of power consumers has been shut down.
