N OT E
When maximum fan speed is calibrated, minimum signal will be sent to hydraulic demand fan solenoid to
obtain maximum fan speed.
Cancel calibration at any time by pressing "Cancel" button.
e.
Record fan speed. Maximum fan speed is 1,625 25 rpm. Press left arrow (5) or right arrow (6) buttons at bottom
of screen until fan speed is approximately 1,000 rpm. Then, press left arrow button at bottom of screen until fan
speed is correct.
N OT E
When right arrow button is pressed, signal to hydraulic demand fan solenoid will be increased. When signal
is increased, fan speed will decrease. When left arrow button is pressed, signal to hydraulic demand fan
solenoid will be decreased. When signal is decreased, fan speed will increase.
When adjusting maximum speed of fan and maximum speed is exceeded, decrease speed of fan below 1,500
rpm and then increase speed of fan to 1,625 25 rpm. This will allow fan speed to be properly set.
