<2> An alarm A35920 or A35921 in the temperature evaluation channel 0 or 1 of
the TM120 is signaled to the next (downstream) drive control via the special
temperature actual 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> A value > 250 °C de-activates the alarm or fault.
