<2> A fault or alarm in the temperature evaluation of the VSM is communicated to the downstream evaluation using special temperature values.
<3> As a result of the wire breakage monitoring the maximum temperature that can be measured is limited to approximate 188.6 °C.
<4> PTC: A value > 250 °C de-activates the alarm or fault.
KTY/PT1000: A value > 188.6 °C de-activates the alarm or fault.
<5> Can only be used with chassis infeeds.
<6> The VECTOR drive object is assigned a dynamic index (p0150).
