ELECTRIC SYSTEM 500E2 SERVICE MANUAL
• High End Proportional — 0 Highest Trigger Setting, F
Least Trigger Setting
1. Set The potentiometer on the transmitter to
minimum, This is done by releasing trigger.
2. Set the “Low End Proportional” hex switch in
the receiver to 0.
3. With the receiver powered, activate the
transmitter and depress the desired function to
control (i.e. boom up, boom down, extend out,
etc.)
4. While maintaining Transmission, slowly
increment the Low End Proportional hex switch
until movement of the activated function begins.
No movement is desired when activating a
function at minimum potentiometer setting;
therefore, back up one step on the hex switch.
Activate each function switch to assure that no
function moves when the switch is on.
Occasionally, a machine will not move even
when the low end potentiometer is at its
maximum setting F. If this occurs, leave the low
end proportional set at F.
5. Now set the potentiometer on the transmitter to
maximum. This is done by fully pulling trigger.
6. Set the High End Proportional to 0.
7. Again activate the desired function. Be careful
since now the function activated will be at full
speed!
8. While maintaining transmission, slowly
increment the High End Proportional hex switch
until a noticeable decrease in function speed is
noticed. Now back up the High End
Proportional hex switch 1 to 2 settings.
9. Failure to properly set the high end pot will
result in a decrease in the motion range of the
trigger when proportioning a function.
The procedure is now complete and proportional control will
function through the complete range of the transmitter
potentiometer.
Antenna Mounting
Care should be taken in installing the antenna. When
mounting antenna, keep in mind that the unit comes
standard with 20 feet (6.1 m) of antenna cable. If driving an
electric over hydraulic pump or any type of electric motor,
mount the antenna away from the motor since that may emit
spurious interference. This will reduce the possibility of
electrical interference. For best operation, mount antenna on
underside of boom. Otherwise pick a location that has the
best visibility and a ground plane with a diameter that is at
least twice the height of the antenna. (Note: it is important
that you do not wrap any excess antenna cable in loops.)
The connector on the end of the cable will hook up to
antenna connector on receiver. See Figure 3-6.
NOTE: Regarding Antenna Placement; Place antenna in
an open area, at least 18 inches (45.7 cm) from any
vertical metal. The position of a “Boom” (over or
around) can effect the antenna’s ability to receive a
signal, creating “Dead Spots”.
