AF Option, Absolute Feedback
The Tritex absolute feedback consists of the combination of the
standard hall feedback and a low power battery-backed counter. The
counter will track the motor’s position as long the battery voltage is
present.
Battery life information:
The battery can provide power to counter for
about one and a half years of power off time, so
for an application that has power applied 50% of
the time the expected battery life would be
approximately three years, more than 50% power
on time = longer life, less power on time = shorter
life. With power off, movement of the motor
causes extra battery power consumption and
will shorten battery life, for applications
that produce frequent or continuous
motor movement with power off, use of the
24 V control logic back should be considered,
see the Control Logic Power Supply section above.
Battery Location:
For 75 mm and 90 mm actuators the battery is located under the
removable wiring access cover. For 60 mm actuators and motors the
option includes a remote mount battery assembly P/N 48224 which must
be mounted externally, typically near the power supply. The battery
connections to the actuator are made through the power connector and
cable. See power connections section for details on battery connection.
Low battery voltage:
When the battery voltage gets below 2 V, a battery fault will be
generated. This fault is typically set to a warning status on the Fault
Enable tab of the System Set page. The warning status can then be
assigned to one of the outputs. The battery voltage can be displayed on
the Diagnostic page while on-line with the actuator. When battery voltage
gets too low to maintain the count value the Homed Status will be off on
the subsequent power up, requiring the actuator to be re-homed. A low
or dead battery does not keep the system from running it just means a
Home is required.
Replacing the battery:
For 75 mm and 90 mm actuators with a removable wiring access
cover, remove the cover and simply remove the battery and unplug the
harness from the two pin connector. The replacement battery kit (Order
Exlar PN 42712) may contain a different mounting clip and connector
that are not used in this application and should be discarded. For 60 mm
