<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 approx. 175 °C.
<4> A value > 250 °C de-activates the alarm or fault.
<5> Can only be used in conjunction with chassis infeeds.
