Under Voltage Fault
When the +15VDC power supply is below +12VDC, a level that would
cause unreliable operation:
For 5 LED amplifiers:
The Run LED turns off, a Fault Output is
generated, and the amplifier is inhibited.
For 1 LED amplifiers:
The Green LED turns off, the Red LED is off, a
Fault Output is generated, and the amplifier is
inhibited.
The following is a list of possible causes:
Main buss line voltage is too low.
Bad power supply.
High Speed Electronic Circuit Breaker (HS/ECB) Fault
When the peak output of the amplifier exceeds 80A for 10 microseconds:
For 5 LED amplifiers:
The Run LED turns off, the HS/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 4 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:
Shorted motor leads.
Motor inductance too low.
Short from the motor lead to ground.
