Runtime monitoring (in automatic mode AUTO)

A
B
The Minimum interval between two cycles (pause) must not underrun a programmable time.
The Maximum cycles per time window must not exceed a programmable number in the running
time window. (E.g. not more than 3 cycles in the last 8 hours)

Filling volume monitoring (in automatic mode AUTO)

Prerequisite: pulse water meter (IWZ) from NFE1.2 or 2.2 connected to MVE1 and activated.
The operator has the option of freely parameterising the filling quantity monitoring. The actual
replenishment quantity must not exceed the maximum quantity per triggering (in one cycle). At the
same time, the Minimum interval between two cycles must not underrun a programmable time.
The Maximum cycles per time window must not exceed a programmable number in the running
time window. (E.g. not more than 3 cycles in the last 8 hours) If these conditions are not met, the
system goes into error. The potential-free fault contact is opened.

Monitoring of initial filling (in FILLING mode)

For the initial filling of a system, the filling mode Filling can be used. The narrower monitoring limits
of the automatic mode are switched off here. Depending on whether the pulse water meter of NFE1.2
or 2.2 is connected to MVE1 and activated, the Max. initial filling quantity or Max. initial filling time
can be monitored. When initial filling has been effected, the system switches automatically to the
automatic mode AUTO.
If the max. initial filling quantity / initial filling time is reached when the system is being filled, the
system sets itself to an error condition; the potential-free fault contact is opened until manual
acknowledgement takes place.

Monitoring, pressure increasing quantity (in automatic mode AUTO)

Prerequisite: Pulse water meter (IWZ) from NFE1.2 or 2.2 connected to MVE1 and activated.Within
this defined replenishment quantity the system pressure must increase by at least 0.1 bar.If this
condition is not met, the system goes into error. The potential-free fault contact is opened until
manual acknowledgement takes place. This monitoring can be switched off by using the input 0.
(e.g. during replenishment into pressureless expansion vessels)

The operator has the option of parameterising
these freely. If the following conditions are not met,
the system goes into error. The potential-free fault
contact is opened until manual acknowledgement
takes place. The actual running time must not
exceed a maximum time per trigger (cycle).
