All monitoring devices fitted must be connected at all times!
Monitoring of motor compartment
The motor compartment monitoring protects the motor winding from short-circuits. The
moisture is measured by an electrode.
Monitoring the motor compartment and sealing chamber
The motor compartment monitoring protects the motor winding from short-circuits. Sealing
chamber control detects fluid ingress through the mechanical seal on the fluid side. In each
case, the humidity is recorded by an electrode in the motor compartment and sealing cham-
ber.
NOTICE! In the Ex version, this monitoring is omitted!
Motor winding monitoring
Thermal motor monitoring protects the motor winding from overheating. A temperature
limiter with a bimetallic strip is fitted as standard. Once the activation temperature has been
reached, deactivation with reactivation lock must take place.
As an option, the temperature can also be measured with a PTC sensor. Thermal motor
monitoring can also be designed as a temperature controller. This allows two temperatures
to be measured. Once the low activation temperature has been reached, an automatic reac-
tivation can be initiated after the motor has cooled down. The unit is forced to deactivate
with reactivation lock once the high activation temperature has been reached.
External monitoring of the sealing chamber
The sealing chamber can be equipped with an external pencil electrode. The electrode regis-
ters fluid ingress through the mechanical seal on the fluid side. An alarm or deactivation of
the pump can therefore take place through the pump control.
Operation on the frequency converter is permitted. Refer to the appendix for the relevant
requirements!
