ELECTRICAL SYSTEM
ENABLING OR DISABLING FAULT DETECTION:
Normally, the main control unit will perform checks of the electrical system during operation. If a fault occurs in a particular system that
system (and possibly others) will be shut down. This can make troubleshooting the system difficult. This option will allow service personnel
to disable some of the fault detection checks to facilitate troubleshooting. This will
not
disable the over-current protection on any of the
systems. To enable or disable fault checking:
1
Turn the master on/off key switch to the off position.
2
Press and hold the scrub off switch and the solution switch.
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 solution red and green indicators
are illuminated.
5
Release both switches.
6
Pressing and releasing the solution switch will now select between “on” or “OFF”. On means that the fault checking option is enabled,
off means that the option 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.
BRUSH TYPE SELECTION:
The HR 2800 / BR 700 can be equipped with two different scrub deck options. One uses cylindrical brushes and the other uses disc
type brushes and pads. This function configures the control unit current settings for each of the scrub deck types. To change from
one type to the other:
1
Turn the master on/off key switch to the off position.
2
Press and hold the scrub off and heavy 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 heavy scrub indicator turns green and the hourmeter/status display shows “dISC” or “CYL”.
5
Release both switches.
6
Pressing and releasing the heavy scrub switch will now select between the two options. For the cylindrical brush unit select “CYL”
and for the disc type unit select “dISC”.
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.
BACK-UP ALARM VOLUME CONTROL:
The HR 2800 / BR 700 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.
