Do not lay KTY or PTC cable of the motor (also shielded) together with control
cable !
• KTY or PTC cable only permissible with double shielding within the motor cable !
The error message E.dOH should never be disabled, otherwise the load shunt is no
longer evaluated. This can cause damage to the hardware!

KTY84
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 winding is no longer guaranteed.
KTY sensors may not be combined with other devices. Otherwise wrong measure-
ments would be the consequence.
Examples for the construction and programming of a temperature control with
KTY84 evaluation can be taken from the application manual.
2.7.4.2 Use of the temperature input in PTC mode
If the temperature input is operated in PTC mode, all possibilities are available for the user
