6.4 Sensitivity Switch Setting (SW2)
When the sensitivity setting is higher, the resolution of the input signal will be higher, and
relatively the dead band will be smaller. Excessive high sensitivity setting may cause the
actuator to keep hunting and could not run to the desired position which will lead to the
thermostat inside the motor to trip because of overheating, and finally the actuator will shut
down. If this situation happens, it is suggested to turn down the sensitivity setting.
