2.8.4.2 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. This can be:
Wiring example in PTC mode
Thermal contact (NC contact)
Temperature sensor (PTC)
Mixed sensor chain
The function can be switched off with Pn.12 = "7" (CP.28) if no evaluation of the input is
desired (standard in operating mode GENERAL). Alternatively a bridge can be installed be-
tween T1 and T2.

KTY sensors may not be combined with other devices. Otherwise wrong
measurements would be the consequence.
The control type COMPACT does not support KTY sensors.
Examples for the construction and programming of a temperature control with
KTY84 evaluation can be taken from the application manual.
KTY sensors are poled semiconductors and must be
operated in forward direction! Connect anode to T1 !
Non-observance leads incorrect measurement in the
upper temperature range. Protection of the motor wind-
ing is no longer guaranteed.
