NOTICE
KTy or PTc cable
• Do not lay KTY or PTC cable of the motor (even shielded) together
with control cable !
• KTY or PTC cable inside the motor cable only permissible with
double shielding !
• The input is base insulated.
The KEB COMBIVERT H6 is delivered with switchable KTY84/PTC evaluation. The
desired function is set with dr33 and works in the following table:

KTY sensors are poled semiconductors and must be oper-
ated in forward direction ! Connect anode to T1 ! Non-ob-
servance leads incorrect measurement in the upper
temperature range. Protection of the motor winding is no
longer guaranteed.

NOTICE
KTY sensors may not be combined with other devices. Otherwise
wrong measurements will be the consequence.
