<2> An alarm A35920 in the temperature evaluation of the TM31 is signaled to the next (downstream) vector control via the special temperature
value -300 °C.
<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> PTC: p4103 = 0 delay time = 0 s.
KTY/PT1000: p4103 = 0 Output from temperature timer even off (0).
