6.2 Condition monitoring and
event display
Note:
see Section 1.4.
The monitoring mode is the normal mode of the
SAFERUN
® . In this mode the following conditions can
be detected and displayed by the system:
Operation within the recommended operating
limits:
Direction of rotation:
Is determined every time the pump is put into op-
eration.
Qmin reached:
Basic setting: Q/Q
opt
= 8%
Qmin undershot:
The minimum flow rate Q
min
recommended by the
manufacturer is undershot; continuous operation in
this condition can result in damage to parts of the
pump.
Qmax reached:
Basic setting: Q/Q
opt
= 120%
Qmax exceeded:
The maximum value of the flow rate Q
max
recom-
mended by the manufacturer is exceeded; con-
tinuous operation in this condition can result in
damage to the pump.
Zero conveyance/Lack of lubrication:
At this operating point safe operation of the pump
can no longer be guaranteed; in this case the
flushing circuit and the lubrication of the bearings
may be suddenly interrupted by overheating and
evaporation of the enclosed medium.
Sudden condition change:
Basic setting: Fluctuations of more than 20% of the
design torque (Q
opt
)
Drive stoppage:
In operation with overloaded magnetic drive …not
admissible --- switch off immediately.
