<1> For p4102[0...23] = 251 °C the evaluation of the appropriate threshold is deactivated.
<2> p4100[0...11]
= 0: Evaluation disabled
= 1: PTC thermistor (with monitoring for short-circuit)
= 2: KTY84 (with monitoring for wire break and short-circuit)
= 4: Bimetal NC contact (no monitoring)
= 5: PT100 (with monitoring for wire break and short-circuit)
= 6: PT1000 (with monitoring for wire break and short-circuit)
<3> For p4103 = 0 s and sensor type "KTY84", "PT100", "PT1000" (p4100[0...11] = 2, 5, 6) the following applies:
- The relevant fault can only be triggered via the fault threshold (the timer output is always logical 0).
For p4103 = 0 s and sensor type "PTC thermistor", "Bimetal NC contact" (p4100[0...11] = 1, 4) the following applies:
- The corresponding alarm and fault are output simultaneously (delay time = 0 s).
<4> Only for 1x2/2x2 wire evaluation (p4108[0...5] = 0, 1).
