#Name Description Corrective Action

1SCR or

Supply

Missing phase on the

input or output terminals,

OR a fault with the

internal switching device.

1. Verify 3-phase input voltage is present at L1, L2 & L3.

2. Verify the motor is properly connected to T1, T2 & T3.

3. Isolate the soft starter and measure resistance between L1–

T1, and between L3–T3. If R < 10Ω, replace the starter.

2Too Hot

Internal temperature of

starter exceeded trip limit

for 1 second (approx),

OR surrounding air

temperature is too high.

1. Increase the time between starts.

2. Install a cooling fan on the starter. (SR22-FAN-45 or -55)

3. Reduce the load on the motor.

4. Increase the size of the starter.

5. Check for sufﬁcient cooling within the enclosure.

6. Replace the starter.

Control

Supply

Low

Volts

Control supply voltage

less than 19V (approx).

1. Verify that DC voltage > 19VDC.

2. If DC voltage > 19VDC & fault will not clear, replace

starter.

Bypass

Relay

Fail

Internal bypass failed to

close at the end of the

start ramp time.

1. Replace the starter.

5Shear Pin

Motor current exceeded

4.4 X rated current for

200 ms (approx).

1. Inspect the load for mechanical binding or jam condition.

2. Correct the source of mechanical binding or remove jam.

3. Uncouple the motor from the load and run the motor.

4. Verify motor current exceeds 4.4 X rated current.

5. If motor current is < 4.4 X rated current, replace starter.

6Over-

current

Motor current exceeded

the overcurrent proﬁle

for the starter. (Refer

to SR22 over current

protection for addtn’l

info)

1. Inspect the load for mechanical binding or jam condition.

2. Correct the source of mechanical binding or remove jam.

3. Lengthen the start time

4. Verify motor current exceeds the proﬁle for the starter. If

motor current does not exceed the proﬁle, replace starter.

NOTE: Reset faults by cycling the enable input.

Overcurrent Level

Overcurrent Protection:

SR22 soft starters include internal overcurrent protection, which becomes active

when the motor current exceeds 110% of the starter’s rating. The RUN (green)

LED ﬂashes rapidly.

Trip Curves:

Cold Curve (green) – ambient 20ºC [68ºF]; start frequency 1/hr

Standard Curve (black) – ambient 40ºC [104ºF]; start frequency 10/hr

Hot Curve (red) – ambient 40ºC [104ºF]; start frequency 20/hr (no derating)

Cooling Time:

Cooling Time partially determined by severity of overcurrent.

Max Cooling Time: 6 min without fan; 1 min with optional cooling fan.

Function:

SR22 soft starters are designed for

reduced-voltage start/stop control of

3-phase AC induction motors.

They use thyristors for controlled

reduced-voltage starting and stopping,

and then switch to internal contacts

for efﬁcient running at rated speed.

DANGER! Hazardous Voltage. Will cause death or serious injury. Hazardous voltage is also present in the

OFF/STOP status of the soft starter when the supply voltage is switched on (Ve).

DANGER ! Tension dangereuse. Danger de mort ou risque de blessures graves. En cas de tension

d’alimentation (Ue) enclenchée, la tension dangereuse existe aussi en position d’Arrêt à la sortie du démarreur

progressif.

¡PELIGRO! Tensión peligrosa. Puede causar la muerte o lesiones graves. Si la tensión de alimentación está

conectada (Ue), existe también en la salida tensión peligrosa con el arrancador suave en estado OFF/ON.
