Описание: Multivac packaging machine, wouldn't start due to 24VDC Ready signals not being received from one of the sub-systems. Initially suspected a malfunction of the main valve on the incoming compressed air line, then the pressure switch (actuated after the main valve opens). Replaced both to no avail. The real culprit was a partial pressure drop (enough to not engage the pressure switch fully) on the pressure switch manifold block.
