Curtiss-Wright | Tritex II AC 90, 115 Rev. X PN39892 7/12/22 77
assigned to one of the outputs or to one of the actuator led indicators.
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.
Replacing the battery:
The battery is located under the removable cover on the
top of the actuator. For replacement unplug the 2 pin
connector and unsnap the plastic band holding the battery in place and
install a new assembly. Order Exlar PN 42712. The AC input terminals
are located in close proximity, for safety remove AC power before
replacing battery.
Important:
If the battery is removed with both AC and Logic power
also removed, leave all power off and do not reconnect the battery for
4 minutes . Once all power is removed from the battery backed logic it
must be allowed enough time to completely bleed down before
restarting. Once power is re-applied the home position must be
reestablished.
Travel limitations.
The counter has a range of +/- 4096 motor revolutions; therefore, the
actuator must operate within this range and if the actuator is moved
beyond this limit a home position must be reestablished.
Speed limitations:
When power is off and the counter is under battery backup, the
maximum rpm the counter can track is 2100 rpm.
