The fault message remains activated until either a subsequent
monitoring remains within the tolerance or a new initialization is
performed. The deactivation of the monitoring (“52. ZERO”=OFF) also
clears any existing fault message.
This monitoring function supplies no useful results when the stops have
not been determined automatically in initialization but the limits set
manually (manual initialization“5.INITM”).
An appropriate diagnosis is made for the top hard stop. The limit value
for this is set with the parameter . Activation of the sealing top function
(parameter “39.YCLS”) is therefore a prerequisite.
8 Monitoring of the dead zone adaptation
If the dead zone increases unproportionally in operation in automatic
adaptation of the dead zone (parameter DEBA = Auto) this points to an
error in the system (e.g. a marked increase in stuffing box friction, play
in the displacement detection, leakage). Therefore a limit value can be
specified for this value (”54. DEBA”, limit value for dead zone
monitoring) which activates the fault message output when it is
exceeded.
