Ordering Information - P-Q Controls 504 Series Operation Manual

OPERATIONS MANUAL
In addition to the proportional outputs, On/Off (digital) outputs are available to energize dump valves,
blocking valves, brakes, buzzers, etc. These solid state auxiliary outputs utilize field effect transistors
(FET's) to provide continuous loads up to 2.5 Amps.
During the final phase of the automated testing, the adjustable parameters of the board are calibrated to
specifications published by the valve manufacturer. 25 turn trimpots are provided on the board to make
small adjustments to "fine tune" the output. Larger adjustments can also be made to drive valves other
than originally intended.
