FUNCTION:
The addition of a second Undercurrent trip or alarm level may be useful as it will indicate if the wrong setpoints are being used for the
wrong speed i.e. normal running current for Speed 2 may be undercurrent for Speed 1 .

FUNCTION:
Two additional Acceleration timers are provided for the two speed motor feature. One timer is for a start in Speed 2 from a stopped con-
dition. The other is an acceleration timer for the transition from Speed 1 to Speed 2. Also, while the motor is running, the SR469 will
ignore Mechanical Jam protection during the acceleration from Speed 1 to Speed 2 until the motor current has dropped below Speed 2
FLA x Overload Pickup value, or the Speed 1-2 acceleration time has expired. At that point in time, the Mechanical Jam feature will be
enabled with the Speed 2 FLA
