6.17.2 Overload protection
The pump is protected by a motor-protection relay. The nominal
current draw must be set manually on the motor-protection relay.
See the specific documentation for the relay on how to set the
trigger level. If the current exceeds the trigger level, the relay will
switch off the pump and the controller will give an alarm. The alarm
has to be manually reset directly on the motor protection relay.

6.17.3 Moisture protection
When a moisture sensor is installed in series with the temperature
sensor, the control unit needs to know how to determine whether
there is a high temperature or moisture in the pump. If the
temperature is too high, normally the temperature sensor will go
back to its normal stage when the temperature has dropped to its
trigger level. If there is moisture in the pump, then the moisture
sensor will keep the series connection open until the pump is
opened and serviced.
To determine which sensor has been active, a cool down
time must be entered. This is the time that will normally pass until
the temperature has dropped enough for the temperature sensor to
return to its normal stage. If the cool down time is exceeded, the
control unit will assume that there is moisture in the pump, and it
will send a moisture alarm.

6.22 GENIbus

GENIbus, the Grundfos Electronics Network Intercommunications
bus, is a fieldbus developed by Grundfos to meet the need for data
transfer in all typical Grundfos motor or pump applications.
Grundfos devices with GENIbus can be wired together in networks
and integrated in automation systems. Each device on the network
must have a unique GENIbus address. GENIbus is based on the
RS485 hardware standard and typically operates at a baud rate of
9600 bits/s.
