A. Normal Operation
The monitor and nozzle are controlled with three toggle switches at each control
point. These switches are marked “STRT-FOG”, “LEFT-RIGHT”, AND “UP-
DOWN”. The switches are of the three position, momentary contact, center-off
type. Simply push and hold the switch(es) to move the monitor to the desired
stream direction, or to adjust the nozzle to the desired spray pattern*. Release
switch when proper stream position or spray pattern is achieved.
B. Manual Override
In the event of power failure to the monitor, the motors may be actuated manually. To
operate a function manually, simply apply a ¾” ratcheting type wrench (either socket type
or ratcheting box end type) to the hex fitting on the motor shaft.
Caution:
Do not use impact drivers to operate manual override nuts. Serious damage to motor gear heads
will result.
*Note: The SM-xxxxE nozzles have a unique ball screw drive that allows the 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.
C. Storing the 8294 Monitor (If available)
See document 98284060 (Found in instruction packet 98421001 included with 81480001 or
81480011Relay Control Module) for a complete description of the operation of the stow
feature.
Warning:
Never activate the “Stow” feature while water is flowing. Serious injury to personnel and
damage to apparatus could result.
Note - Any directional command (left, right, up, or down) will cancel the “stow” command.
To continue the command, reactivate the “Stow” feature.
Note – In the event power is cycled in the middle of a stow operation; when the processor
powers up the stow output will show that the monitor is NOT stored.
