Attention
Info
Examples for the construction and programming of a temperature control with KTY84 eval-
uation can be taken from the application manual.

2.6.4.2 Use of the temperature input in PTC mode

If the temperature input is operated in PTC mode, all possibilities are available for the user
within the specified resistance range (see „temperature detection T1, T2").This can be:
Thermal contact (NC contact)
Temperature sensor (PTC)
Mixed sensor chain
Figure 27:
The function can be switched off with Pn.12 = "7" (CP.28) (standard at F5-General) if no eval-
uation of the input is desired. Alternatively a bridge can be installed between T1 and T2.

Connection of a KTY sensor
KTY sensors may not be combined with other devices. Otherwise
wrong measurements would be the consequence.
Temperature Control
Wiring example in PTC mode
KTY sensors are poled semiconductors and must be
operated in forward direction! Connect anode to T1 !
Non-observance leads incorrect measurement in the up-
per temperature range. Protection of the motor winding
is no longer guaranteed.
