Abstract

A duplicate two-channel pneumatic control system enables a flow of compressed air to be delivered to a consumer by applying two control signals essentially simultaneously. The system includes a set-up of pneumatic valves (21, 22; 21', 22'; 40, 40') and accumulators (30, 30'), wherein the set-up is adapted to monitor all valves and accumulators with respect to their correct function in each working cycle. The control system is adapted to prevent compressed air being delivered to the consumer when any of the system components malfunctions or when the control signals are applied at a time difference which is greater than a pre-selected time difference.
