ELECTRICAL SYSTEM
SPECIAL PROGRAM OPTIONS (CONTINUED)
Enabling or Disabling the Vacuum Automatic Shutoff Option:
FACTORY DEFAULT: ENABLED
To indicate to the operator that the recovery tank is full, the control system will automatically turn off the vacuum and display “FULL” on the
hourmeter/status display if the recovery tank becomes filled. If problems are encountered with the vacuum automatic shutoff feature, such as the
vacuum shutting off even if the recovery tank is not full, this feature can be disabled. To enable or disable this feature perform the following steps:
1
Turn the master on/off key switch to the off position.
2
Press and hold the vacuum switch.
3
While holding the vacuum switch turn the master on/off key switch to the on position.
4
Continue to hold the vacuum switch until the hourmeter/status display shows “d” (disabled) or “E” (enabled) and the vacuum indicator is
green.
5
Release the vacuum switch.
6
Pressing and releasing the vacuum switch will now select between “E” (enabled) or “d” (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:
FACTORY DEFAULT: Dependent on machine model
To operate properly and avoid potential damage to the electrical system, the control must be programmed for the type of scrub deck installed on
the machine. There are three possible types. One uses cylindrical brushes and the other two use disc type brushes and pads. This function
configures the control unit current settings for each of the scrub deck types. To select the proper type:
1
Turn the master on/off key switch to the off position.
2
Press and hold the solution switch.
3
While holding the solution switch, turn the master on/off key switch to the on position.
4
Continue to hold the solution switch until the solution indicator turns green and the hourmeter/status display shows “d”, “C” or “1”.
5
Release the solution switch.
6
Pressing and releasing the solution switch will now select between the three options. For the cylindrical brush unit select “C”, for the 3/4
HP disc type units (24V & 36V) select “d”. Note: The third displayed selection “1” is not to be used, it is programmed for possible future
engineering use. If “1” is selected electrical overload damage to the brush motors could result (which also would void the warranty).
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.
CAUTION!
Improperly setting this parameter can result in serious damage to the machine. If this is set for 1 HP motors with 3/4 HP motors installed
on the machine, the motors may be overloaded which can cause overheating and permanent damage to the motors. It could also
create a fire hazard.
Enabling/Disabling the Optional Brush Remove Feature:
FACTORY DEFAULT: DISABLED
With the installation of the optional remove relay kit, disc type machines can be configured for automatic brush removal. The automatic remove
functions are disabled at the factory. If it is desired 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 scrub-off/pressure-decrease and vacuum 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 “E” or “d” and the vacuum indicator turns red.
5
Release both switches.
6
Press and release the vacuum switch to select “E” (enabled) or “d” (disabled).
7
Turn the master on/off key switch to the off position.
