5.7.1 Recommended: monitoring equipment and protective equipment

NOTE
For pump sets in VdS-approved sprinkler installations
For pump sets in VdS-approved sprinkler installations, also observe VdS guideline
VdS CEA 4001!
The following monitoring equipment and protective equipment is recommended for
proper operation of the pump set:
If there is any risk of:
▪ Highly fluctuating water levels
▪ Wells with temporary low yields
A lightning protection device cannot offer
protection against direct lightning strikes, however,
it will protect the pump set against atmospheric
overvoltages and any lightning strikes nearby.
▪ Failure of one phase resulting in overloading of
the remaining two phases
▪ Permissible motor temperature exceeded by
system conditions, e.g.:
– Deposits on the stator
– Installation in stagnant water
– Dirt/sand deposits in the stator area
– Major temperature rise in the fluid handled
– Motor operating on a frequency inverter
Also recommended:
▪ Overcurrent / undercurrent
▪ Earth fault / short circuit
▪ Current asymmetry
▪ Overvoltage / undervoltage
▪ Vibrations
UPA / UPA S
Monitoring option
▪ Semi-automatic or fully
automatic dry running
protection equipment
(e.g. integrated in KSB's
control unit UPA Control)
▪ Lightning protection with
earthing terminal
(available from KSB)
▪ Pt100 resistance
