Introduction VLT® HVAC Drive Programming Guide RefMAX Determines the relationship between the reference input at 100% full scale value (typically 10 V, 20mA) and the resulting reference. The maximum reference value set in par. 3-03 Maximum Reference. RefMIN Determines the relationship between the reference input at 0% value (typically 0V, 0mA, 4mA) and the resulting reference. The minimum reference value set in par. 3-02 Minimum Reference.
1 1 VLT® HVAC Drive Programming Guide Introduction FC Standard Bus Includes RS 485 bus with FC protocol or MC protocol. See par. 8-30 Protocol. The frequency converters' built-in DC coils produce a high power factor, which minimizes the imposed load on the mains supply. Thermistor: A temperature-dependent resistor placed where the temperature is to be monitored (frequency converter or motor). 1.1.7 Safety Precautions Trip A state entered in fault situations, e.g.
Introduction VLT® HVAC Drive Programming Guide Warning against unintended start 1. The motor can be brought to a stop by means of digital commands, bus commands, references or a local stop, while the frequency converter is connected to mains. If personal safety considerations (e.g. risk of personal injury caused by contact with moving machine parts following an unintentional start) make it necessary to ensure that no unintended start occurs, these stop functions are not sufficient.
