BMA Shield PMC-R Operating Manual
RCP Broken Chain Warning If an RCP broken chain warning occurs in a shield this indicates that when the shield was advanced the Rear Conveyor Pull Cylinder did not extend past past the stroke value set in the RCP Rear.adv.ext parameter and that it is likely the Rear Conveyor Pull Chain is broken. These are warnings only and will not inhibit any system operations. Warning messages are prevented from occurring when the RCP reed rods are ignored or faulty and when Shields are advancing to a target line since it is not expected the RCP cylinder will fully extend as the shield may not fully advance.
