EXT PTC
This signal monitors the temperature of the motor. A high resistance or open circuit
indicates that the temperature of the motor exceeds the rated level. If a temperature sen-
sor is not used, the circuit must be strapped. If more than one motor is used, all PTC
resistors are connected in series.
