Digisensor
There are two LEDS on a Digisensor. To check for proper operation, apply power to the Digisensor and
observe these LEDS. See Figure 18.
Power may be supplied by the machine or by using a fresh 9 Volt transistor radio battery. Connect the
battery plus to the red wire, and the battery minus to the black wire. One or both LEDS should be on. If
neither LED turns on, replace the Digisensor.
Next, rotate the Digisensor’s potentiometer shaft.
When it is turned fully counter-clockwise, the left
“direction A” LED turns on. When the shaft is turned
fully clockwise, the right “direction B” LED turns on.
There is a small area when the potentiometer shaft is
turned about halfway where both LEDS are on. This is
important for aligning the Digisensor to the Joystick
controller.
Whenever a Digisensor is mounted to a joystick
controller, the mechanical alignment must be checked
and adjusted if necessary. This is important as the
Superflex 4 Controller depends on proper Digisensor
signals to operate the valves. Check the Digisensor
LEDS when the Joystick handle is in its center or “off”
position. NOTE - it may be necessary to operate the
joystick’s on/off micro-switch to apply power to the
Digisensor. Both LEDS must be ON when the handle
is centered. If this is not the case, rotate the shaft until
both LEDS turn on, and then tighten all mechanical
hardware.
