After entering the motor parameters (see the chapter "Parameterisation of the ZAdyn4CA HY"), the
turning direction of the pump must be checked. For this purpose, start a travel upwards in inspection
mode (see the chapter "Travelling in inspection mode"). If the pump runs backwards (pay attention to
sound of pump), the turning direction must be changed. To do so, there are the following possibilities:
•
Swapping two motor phases (e.g. U and V)
•
Changing the parameter

Motor temperature monitoring (X-MT)
Information
The X-MT connection terminal is a standard part of the ZAdyn4CA HY.
Information
The detection of over temperature of the motor doesn't cause a drive interruption. The current drive
will be completed.
If an over temperature of the motor will be detected at stop, there is no further drive possible.
The temperature monitoring is carried out according to IEC 61800-5-1:2003-02 (switching point at
3500
Ω
)
The following sensor types can be used:
•
PTC thermistor (PTC according to DIN 44082)
•
Temperature sensor KTY84-130
•
Thermal circuit breaker
The used sensor has to be parametrized in the menue
