Power Derating Function during High Temperature
Condition
During operation the controller limits the power provided to the
motor according to:




WARNING! The user must set the gas type load (WIN 157) and Cooling mode (WIN 106) before
starting the pump.
The applied power limit is readable by serial line (WIN 155).
If the pump body temperature exceed 55 °C or the pump bearing
temperature exceed 60 °C or the Controller temperature exceed
60 °C, the controller goes in status 6 (Fail).
The controller compensates, according to maximum available power,
the power loss estimated due to the length of the pump cable.
In order to avoid wrong power compensations it is fundamental that
the user sets the correct pump cable length (by considering the unit
cable and possible extension cables) by means of the user interface or
with WIN 148.
