▷ Never start up a pump set with incompletely connected cables or non-
operational monitoring devices.
CAUTION
Incorrect wiring
Damage to the sensors!
▷ Observe the limits stated in the following sections of this manual when
connecting the sensors.
The pump set features sensors designed to prevent hazards and damage to the pump
set.
Measuring transducers are required for analysing the sensor signals supplied. Suitable
devices for 230 V~ can be supplied by SFA.
NOTE
Reliable and safe operation of the pump within the scope of our warranty is only
possible if the sensor signals are properly analysed as stipulated in this manual.
All sensors are located inside the pump set and are connected to the power cable.
For information on wiring and core identification please refer to the "Wiring
diagrams" section.
The individual sensors and the limit values to be set are described in the following
sections.
5.4.1.6 Motor temperature
CAUTION
Insufficient cooling
Damage to the pump (set)!
▷ Never operate a pump (set) without operational temperature monitoring.
The pump set is equipped with double monitoring of the winding temperature. Two
bimetal switches (terminals 21 and 22, max. 250 V~/2 A) serve as temperature control
devices which open when the winding temperature is too high.
Tripping must result in the pump set cutting out. Automatic re-start is permissible.
