Elkhart Brass Scorpion RF 8294-07 - Manual (Page 15)

For safety reasons, once oscillation has stopped the oscillation limits need to be reprogrammed before
it can be re-engaged. The nozzle fog, stream, and discharge elevation functions can be operated while
the monitor is oscillating.
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.
Important:
Using the horizontal override nut when the power to the receiver is off or
the horizontal motor is disconnected will move stow position from its original
programmed position. See Installation Step 4 to realign stow position even if stow
feature is not utilized.
Warning:
Do NOT use impact drivers to operate the manual override nuts. Serious
damage to motor gear heads will occur.
Storing the Monitor
Elkhart Brass recommends that a stow position be set and the stow routine be utilized to place the
monitor in it stowed position after each use.
These monitors have a user selectable stow position (see Installation Step 4 section for instructions).
After the water supply to the monitor has been turned off, simultaneously press the STOW and FOG
buttons on the primary panel mount RF transmitter (buttons must be held down for a minimum of 3
seconds). The monitor will automatically rotate horizontally to the stow position previously
programmed, and either lower or raise the discharge to its mechanical stop (depending on the position
of switch A position 1 on the receiver board). Prior to stowing the monitor, the stow signal output
provides a ground signal.
Any directional command (left, right, up, down, fog or straight stream) will cancel the stow command,
and the stow output signal will continue to provide a ground. To stow the monitor, the stow command
must be reactivated.
Warning:
Never activate the stow feature while water is flowing. Serious injury to
personnel and damage to apparatus could result.
Warning:
It is up to the system designer to appropriately handle the open circuit
condition of the stow signal. In the open circuit mode there is no source to turn off the
stow signal load, which may lead to erroneous signal indications if not handled properly.
The stow signal is capable of sinking 250mA maximum. Exceeding this value may blow
the internal fuse and the stow output will no longer be able to provide a ground.
Important:
Most test lights draw in excess of 1A.
