Low Speed Electronic Circuit Breaker (LS/ECB) Fault
When the RMS output of the amplifier exceeds 13A for 5 seconds:
For 5 LED amplifiers:
The Run LED turns off, the LS/ECB LED turns
on, a Fault Output is generated, and the
amplifier is inhibited.
NOTE:
This is a latched condition.
For 1 LED amplifiers:
The Green LED turns off, the Red LED
displays 3 flashes, a Fault Output is
generated, and the amplifier is inhibited.
NOTE:
This is a latched condition.
The following is a list of possible causes:
Binding or stalling of motor shaft due to excessive mechanical
overload.
Overload of amplifier output to motor.
Large reflected load inertia.
Over Temp Fault
When the amplifier heatsink temperature has reached a level that, if
exceeded, would damage the output transistors:
For 5 LED amplifiers:
The Run LED turns off, the OVER TEMP LED
turns on, a Fault Output is generated, and the
amplifier is inhibited.
NOTE:
This is a latched condition.
For 1 LED amplifiers:
The Green LED turns off, the Red LED
displays 1 flash, a Fault Output is generated,
and the amplifier is inhibited.
NOTE:
This is a latched condition.
The following is a list of possible causes:
Loss of cooling, or fans are defective, or airflow is blocked.
Excessive rise in cooling temperature due to cabinet vents being
blocked or excessive hot air being ingested.
Extended operational duty cycle due to mechanical overload of motor
or defective motor.
