PRODUCT NAME: Navigator Pro Valve Controller
AKRON BRASS STYLE NUMBER: 9321, 9333 and 9335
MOTOR DRIVER FIRMWARE UPDATE TO VERSION 1-10
A condition has been reported to Akron Brass where the position of the valve (% Open/Closed) may be displayed
inaccurately after a power cycle. This inaccuracy may be up to 6%. While there is no impact to valve function, the
Akron Brass Company is recommending updating the Motor Driver System Firmware to version 1-10 to eliminate
this possibility.
NOTE: Updating firmware will not overwrite valve assignments, calibrations, or configurations.
