    modutrol IV motor

    This mod motor is mounted 2 inches form top of unit, so I can't see anything....The motor is driven by a johnson controls discharge temp thermostat with a 2-10 vdc output to drive a gas valve to maintain discharge temp. My quetion is...is the interface control mounted in the mod motor adjustable? The motor only drives 35-40 degrees with max and min voltages applied. The motor is supposed to drive 90 degrees.

    I believe it is adjustable. I usualy hook my signal generater to the actuater to calibrate it. That way I know it will drive properly when I put the control wires back on it.
