<2> An alarm A35922 or A35923 in the temperature evaluation channel 2 or 3 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.
4000.00 μs
<5> For KTY/PT1000: p4103[0...3] = 0 Output from Timer always off (0).
For PTC/bimetal: p4103[0...3] = 0 delay time = 0 s.
<6> KTY/PT1000 = For monitoring wire breakage and short-circuit.
PTC = For monitoring short-circuit.
Bimetal = No monitoring.
