ELECTRICAL INSTALLATION INSTRUCTIONS
A . JOYSTICK AND VALVE ATTACHMENT
The following steps will prepare the joystick and valve for attachment to the control harness .
STEP 1
Plug Power and Valve Harness (part #721564 Figure 4) into Control harness power/valve
connector on the monitor (Figure 2) .
STEP 2
Plug either end of the CAN Communications Harness (part #721565 Figure 4) into Control box CAN
connector located on the monitor (Figure 2) .
STEP 3
Plug the remaining end of the CAN Communications Harness (part #721565) into the CAN Joystick .
STEP 4
Plug the mating end of a Valve Harness (part #721290) into the Power and Valve Harness (part #721564)
valve connector located at the vehicle end of the harness .
STEP 5
Plug the remaining end of the Valve Harness (part #721290) into the Valve Actuator Motor connector .
STEP 6
Recognizing that as the monitor moves in the rotation axis, the three cables move with it . You must
allow sufficient free length of the cables before affixing to a stationary point . Assure that the cables
experience no sharp bends throughout the rotation range of travel .
B . BATTERY ATTACHMENT
The Battery connection should be the last connection made .
Connect the flying leads at the end of the Power and Valve Harness (part #721564) opposite the monitor
to a switched battery power source . The black lead should connect to battery negative, and the red lead
to battery positive . Use butt splices or other appropriate method of choice .
D . MECHANICAL MONITOR ATTACHMENT
The Bumper Monitor is to be mounted on the waterway with a 2” NPT thread. The front of the monitor is identified in Figure 2. The 2”
NPT Inlet will have the Quick Disconect Latch Pin Hole facing to the right when looking towards
the vehicle .
E . THE ROTATIONAL AND ELEVATION STOPS SET THE BOUNDARIES FOR THE AREA IN WHICH THE BUMPER MONITOR IS ALLOWED
TO TRAVEL . The monitor is shipped with rotation stops at 90˚ right, and at 90˚ left . All other positions are achieved by switching the
factory set stop and the plug in the desired stop location . Both the stops and the plugs have a 1/2 inch hex head . Refer to Figure 2 and
3 to determine which stop location is needed for the desired rotation . The elevation stop sets the upper limit of the elevation . The
monitor is shipped with elevation stops at 90° above horizontal and 45˚ below horizontal to meet NFPA . All other vertical positions
are achieved by switching plugs and stops to the desired locations as indicated in Figures 2 and 3 . Additional stops and plugs are
provided in the instruction kit for all possible elevation and rotation positions .
OPERATING INSTRUCTIONS
A . Joystick with Trigger FOR VALVE
To change the nozzle pattern toward the straight stream or fog press the corresponding button on top of the Joystick .
To change the horizontal position right or left move the Joystick towards the appropriate direction . To change the vertical
position up or down move the Joystick forward for down and backwards for up . To open and close the valve, press
the trigger to open the valve and release the trigger to close the valve . The valve can be maintained open by quickly pressing the
trigger twice . Press the trigger and release once to close the valve .
B . Quick Disconnect
The Bumper Monitor is designed for an optional quick disconnect inlet . If equipped with a quick disconnect inlet, first mount the inlet
on the 2” NPT piping. Make sure the latch pin on the inlet is facing towards the right (see figure 2). Place the monitor into the inlet so
the two guide pins line up with the groove . Slide the monitor all the way in and rotate 15° clockwise until the latch pin locks in place .
To remove the monitor, pull the latch pin, rotate the monitor 15° counterclockwise, and lift the monitor out of the inlet .
WARNING:
Make sure the monitor is locked in place before flowing water . The latch pin must be flush
with the housing . (See warning tag on the quick disconnect inlet for further information)
C . MANUAL OVERRIDE CONTROLS
THE MANUAL OVERRIDE CONTROL IS TO BE USED WHEN THE POWER TO THE MONITOR IS OFF . A 1/4 inch Allen
wrench will actuate the overrides . An override crank is included on the monitor . See figure 2 for location of crank . To use the manual
override insert the hex head end of the override crank in the hexagon shaped hole . Then rotate or spin the override crank either
clockwise or counterclockwise to aim the monitor in the desired direction .
WHEN THE OVERRIDE CRANKS ARE NO LONGER IN USE PUT THEM BACK IN THE STORAGE POSITION .
WARNING:
DO NOT USE THE ELECTRIC CONTROLS WHEN THE OVERRIDE CRANK IS BEING USED OR IS IN POSITION FOR USE .
