BRAKE CONTROL AND TEMPERATURE DETECTION
4.3.2 Specication and connection of the temperature detection
DANGER
Use only sensors with basic insulation to mains potential !
Danger to life due to electric shock !
► The inputs of the temperature detection have „basic insulation“
against SELV voltage of the control.
► Asystemvoltage(Phase–PE)of300Visdened.
NOTICE
Malfunctions due to incorrect cable or laying!
Malfunctions of the control due to capacitive or inductive coupling.
► Do not lay cables of the motor temperature sensor (also shielded)
together with the control cable !
► Cables of the motor temperature sensor inside the motor cable only
permissible with double shielding !
A switchable KTY84/PTC evaluation is implemented in the KEB COMBIVERT. The de-
sired operating mode can be adjusted by software (dr33).
