ADAPTIVE ELECTRONICS
A perfect duty cycle consists of a waveform whose "high" and "low"
conditions are of the same duration (50%/50%). It is possible over
time for the duty cycle and edge separation to change due to com-
ponent drift, temperature changes, or mechanical wear. The Adap-
tive Electronics extend the life of the AV45 by constantly monitor-
ing and correcting duty cycle and edge separation over time.
FAULT-CHECK
If the Adaptive Electronics reach their adjustment limit, the LED will
turn red and Fault-Check alarm will notify the drive and operator
of an impending failure. This output can occur before a failure,
allowing steps to be taken to replace the unit before it causes un-
scheduled downtime. Fault-Check annunciation is available as an
"alarm" output through the connector.
SAFETY
The AV45 is not considered as a safety device and is not suitable
for connection into a safety system. The mechanical overspeed
switch (option 6xx) is suitable for connection into safety systems.
CAUTION
Do not disassemble mechanical overspeed option.
Doing so may modify the overspeed set point or
cause the switch to malfunction. If the factory seals
are not intact on the overspeed switch, do not use
it--return to the factory for service and calibration.
WARNING
Installation should be performed only by quali-
fied personnel. Safety precautions must be taken
to ensure machinery cannot rotate and all sourc-
es of power are removed during installation.
