Abstract

In addition to a priming stage (11), the timing chain has at least two stepping modules (12, 13), of which each has a 5/2-way valve constructed as a pulse valve. The 5/2-way valve (53) is constructed and wired in such a way that during priming by a setting signal of a preceding stage (11) it is held by the continuing signal at the associated signal input (29) in a position in which its associated signal output (25) receives no compressed air. The timing chain (10) therefore remains stationary at the particular point even in the event of a permanent signal of a defective limit switch, without skipping a step and running on. <IMAGE>
