Scrub mode description:
On the 3800 / BR 1100 / 2042 and BR 1100C-XL, both the normal and heavy scrub modes are independently programmable to have user adjustable
or fixed scrub pressure settings.
If the adjustable option is selected (factory default), the operator will be able to vary the amount of scrub pressure while operating the machine.
Maximum pressure limits can be programmed for both the normal and heavy scrub modes. This can be used to prevent the use of too much pressure
while still allowing the operator some adjustment of the scrub pressure.
If the fixed option is selected, a pre-set scrub pressure will be used for each mode (normal/heavy). The pre-set pressure settings can be selected
by a special key sequence described later. This would allow a supervisor to set up two different scrub pressures (normal/heavy) thereby preventing
the operator from having the capability to vary the pressure throughout the full range.
The scrub pressure can be set from 1 to 7 for cylindrical brush machines and 1 to 12 for disc brush/pad machines. The allowable range for the
normal scrub mode is 1 through 4 and the range for the heavy scrub mode is (normal limit + 1) through 7 or 12 depending on model. This number
is a relative indication of scrubbing effort. The actual pressure applied will vary depending on the floor surface and the type of pad/brush used.
Scrub mode operation (adjustable):
If the adjustable option is selected (factory default) the scrub mode operation is as follows:
Pressing the normal scrub button will enable the scrub system and set the scrub pressure to the last selected value for the normal scrub mode.
The status display will momentarily display the scrub pressure setting. This is indicated by “PA” (Pressure Adjustment) followed by a number.
Subsequent presses of the normal scrub button will step the pad pressure setting through the allowable range up to the maximum value
programmed for the normal scrub mode. Once the maximum value is reached the pressure setting will step back to 1. The factory default maximum
for the normal scrub mode is 4.
Pressing the heavy scrub button will enable the scrub system and set the scrub pressure to the last selected value for the heavy scrub mode. The
status display will momentarily display the scrub pressure setting. This is indicated by “PA” followed by a number.
Subsequent presses of the heavy scrub button will step the pad pressure setting through the allowable range up to the maximum value programmed
for the heavy scrub mode. Once the maximum value is reached the pressure setting will step back to (normal scrub limit + 1). The factory default
maximum for the normal scrub mode is 7 (cylindrical) or 12 (disc).
Scrub mode operation (fixed):
If the fixed option is selected the scrub mode operation is as follows:
Pressing the normal scrub button will enable the scrub system and set the scrub pressure to the pre-set normal scrub pressure setting. The operator
will not be able to adjust the pressure for the normal scrub mode. The status display will momentarily display the scrub pressure setting. This is
indicated by “PA” followed by a number.
Pressing the heavy scrub button will enable the scrub system and set the scrub pressure to the pre-set heavy scrub pressure setting. The operator
will not be able to adjust the pressure for the heavy scrub mode. The status display will momentarily display the scrub pressure setting. This is
indicated by “PA” followed by a number.
Scrub mode programming for user adjustable scrub pressure:
To program the normal scrub mode for user adjustable scrub pressure perform the following steps:
1
Turn the master key switch off.
2
Press and hold the normal scrub button.
3
Turn the master key switch on while continuing to hold the normal scrub button until the status display shows “PA * “, where * is a number
from 1 to 4.
4
Press and release the normal scrub button until the display shows “adjustable”.
5
Press and release the scrub off button to save the setting.
6
The display will now change to “PA” followed by a number in the range of 1 to 4. This is the maximum pressure that will be allowed for the
normal scrub mode.
7
Press and release the normal scrub button to select the desired limit.
8
Press and release the scrub off button to save the pressure level.
9
The display will now show “done” indicating that the normal scrub mode is programmed.
10
Turn the master key switch off.
