This system limits the closing device to effect a single attempt while the signal to close is maintained. If the device fails to complete a satisfactory close operation whilst the close signal is maintained, then attempts at further reclosing (pumping) are inhibited. An anti-pumping can be achieved in the closing control circuit in various ways, either by using circuit-breaker mechanism auxiliary switches or a timing relay. It only allows a single closing pulse to the closing device, which resets when the initial closing signal is released.  1, fiche 1, Anglais, - anti%2Dpumping%20system
