OPERATING INSTRUCTIONS
Normal Operation
The 8294-07 Scorpion RF LED with position display uses the standard Left/Right, Up/Down, and
Fog/Stream commands to provide stream direction and pattern adjustments.
To move the monitor left or right, press and hold the LEFT or RIGHT button until the monitor
discharge is in the correct position, or a mechanical stop is reached.
To move the monitor up or down, press and hold the UP or DOWN button until the monitor
discharge is in the correct position, or a mechanical stop is reached.
To adjust the stream pattern, press and hold the FOG or STREAM button until the desired stream
pattern is reached.
Any combination of left or right, fog or stream, and up or down can be used to achieve motion
horizontal, vertical, or nozzle commands simultaneously. If the LEFT and RIGHT buttons are pressed at
the same time, the monitor will stop all motion. To continue motion, release both buttons and repress
the desired direction button. This is also true for the up/down and fog/stream commands.
The handheld remote transmitter has a power saving feature that turns the transmitter power off if no
signal is sent for 5 minutes. Press and hold the “ON/OFF” button until the Power LED illuminates to
reactivate the transmitter. The “Low Battery” LED will flash slowly when the battery voltage drops below
a predetermined level. When the low battery LED flashes rapidly, the batteries are nearly discharged
and should be replaced immediately.
NOTE: The SM-1250E and SM-2000E nozzles have a unique ball screw drive that allows motor to
“free wheel” at the end of pattern travel in either the straight stream or wide fog positions. No slip
clutch or current limiting feature is used with these nozzle drives.
Oscillation Function
The 8294-07 Scorpion RD LED with position display supports oscillation in either a square or sine wave
pattern (both motors moving at the same time). The first pin of switch block A on the monitor receiver
board designates whether the monitor will oscillate in a square or sine wave pattern. Selecting ‘up’ will
oscillate in a square pattern, while selecting ‘down’ will oscillate in a sine wave pattern. The oscillation
limits are set using the handheld or truck mount RF transmitters.
Position the monitor at either the left or the right limit of oscillation.
o
For sine wave pattern, position at the lower left or upper right limit of oscillation.
Press and release the OSCILLATE button.
Move the monitor to the other limit of oscillation.
o
For sine wave pattern, position at the alternate upper or lower limit of oscillation.
Press and release the OSCILLATE button.
The monitor will oscillate between the limits until the oscillation button is pressed again. Pressing
the left or right button on one of the controllers will also stop the oscillation.
