Vibration & temperature
This uses a single sensor per motor that can detect vibration and temperature at the same time. One type of sensor can be
used. (Sensor model: K6CM-VBS1)
Insulation resistance
This uses one ZCT per motor to detect leakage current. One type of ZCT can be used. (ZCT model: K6CM-ISZBI52)
