ELECTRICAL SYSTEM
RAMP MODE FEATURE:
Under normal conditions the operator will use the throttle for accelerating and decelerating/stopping. This works well unless the
machine is used to scrub on an inclined surface. In this case, using the throttle to decelerate (such as braking while going down hill)
will cause the squeegee to raise and the solution flow to shut off; or allowing the throttle to go to neutral (such as coasting down hill)
will cause the scrub brushes to stop. To prevent this the control unit can be placed into a “ramp mode”. If the ramp mode is enabled
and selected
, the scrub brushes will continue to operate as will the vacuum and solution system even if the throttle is in neutral or
reverse. In addition, the squeegee will not raise when in reverse. The ramp mode is
deselected
by pressing any of the three scrub
switches (scrub off, normal scrub, heavy scrub) or if the operator gets off the seat. In order to be able to
select
the ramp mode, it must
first be enabled. To enable this feature perform the following steps:
1
Turn the master on/off key switch to the off position.
2
Press and hold the horn and the normal scrub switches.
3
While holding both switches turn the master on/off key switch to the on position.
4
Continue to hold both switches until the hourmeter/status display shows “OFF” or “on” and the normal scrub green and yellow
indicators are lit.
5
Release both switches.
6
Pressing and releasing the normal switch will now select between “on” or “OFF”. On means that the ramp mode is enabled, off means
that the ramp mode is disabled.
7
To save the new setting, turn the master on/off key switch to the off position.
8
The new setting will be saved and will remain in effect until it is changed again.
Once the ramp mode is enabled, it can be
selected
by pressing and holding either the normal or heavy scrub switches (whichever is
currently selected) for approximately 1 second while scrubbing. The scrub motor must already be on to enter the ramp mode. While
the ramp mode is active, the scrub indicator (either normal or heavy) will alternately flash between green and yellow. As mentioned
above, pressing any of the scrub switches or getting off the seat will
deselect
the ramp mode. NOTE: when selecting the ramp mode,
the scrub pressure will increment as soon as the scrub switch is pressed. After the one second delay the pressure will automatically
be decremented to the original value.
BACK-UP ALARM VOLUME CONTROL:
The 2800/BR700 is equipped with an audible warning device which functions as both a horn and a back-up alarm. The volume of the
back-up alarm can be adjusted to one of ten settings. Off is the minimum setting and 9 is the maximum setting. To change the back-
up alarm volume perform the following steps:
1
Turn the master on/off key switch to the off position.
2
Press and hold the horn switch.
3
While holding the horn switch turn the master on/off key switch to the on position.
4
Continue to hold the horn switch until the hourmeter/status display shows “OFF” or a number from one to nine depending on the
current volume setting.
5
Release the horn switch.
6
Pressing and releasing the horn switch will now select the volume level. The level will increment from OFF to 9. 9 being the loudest.
To hear the back-up alarm volume select the reverse direction by pressing lightly on the throttle.
7
To save the new setting, turn the master on/off key switch to the off position.
8
The new setting will be saved and will remain in effect until it is changed again.
