Ready LED
Description
x 1
Power Circuit: Check mains supply (L1, L2, L3), motor circuit (T1, T2, T3), soft starter SCRs
and bypass relays.
x 6
Supply Frequency: Check mains voltage is available and supply frequency is in range.
x 8
Network Communication Failure (between interface and network): Check network
connections, settings and configuration.
x 9
Starter Communication Failure (between starter and interface): Remove and refit
accessory interface.
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 pushbutton to momentarily open the stop input (open
A1-02).

In two wire control, if the soft starter tripped with wa 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.
