5.2.1 Supply Frequency Protection
The soft starter will trip on supply frequency if the frequency rises above 72 Hz or falls below 40 Hz for more than five seconds while the
soft starter is running. These trip points are not adjustable.
In pre-start, starting and stopping modes the high and low frequency limits both apply with no time delay.
A supply frequency trip will also occur if:
•
all three input phases are lost while the soft starter is running
•
all three input phases fall below 120 VAC at start or while the soft starter is running
• the line contactor opens while running
5.3 Reset
Trips can be cleared by pressing the Reset button on the soft starter, sending a Reset command from the serial communications
network, or by switching the control inputs.
To clear a trip via the control inputs, the soft starter requires a closed to open transition on the stop input (02).
•
In three-wire control, use the external stop button to momentarily open the stop input (open A1-02).
•
In two-wire control, if the soft starter tripped with a start signal present, remove the start signal (open A1 to 01, 02).
The Reset button is located on the front of the unit, above the adjustment switches.
The soft starter will trip again immediately if the cause of the trip still exists.
