ELECTRICAL SYSTEM
To program the heavy scrub mode for fixed scrub pressure perform the following steps:
1
Turn the master key switch off.
2
Press and hold the heavy scrub button.
3
Turn the master key switch on while continuing to hold the heavy scrub button until the status display shows “PA * “, where * is a
number from 2 to 9.
4
Press and release the heavy scrub button until the display shows “non-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 (normal scrub limit + 1) to 7 (cylindrical) or 9 (disc). This
is the scrub pressure that will be used for the heavy scrub mode.
7
Press and release the heavy 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 heavy scrub mode is programmed.
10
Turn the master key switch off.
NOTE:
Either scrub mode (normal/heavy) may be programmed for adjustable or fixed scrub pressure independently. They do
not
have to be programmed the same.
RESTORING THE SCRUB MODES AND PRESSURES TO FACTORY DEFAULT SETTINGS:
FACTORY DEFAULT: Normal scrub = adjustable, limit = 4; Heavy scrub = adjustable, limit = 7 or 9 depending on scrub deck type.
If it is desired to restore the normal and heavy scrub modes and pressure settings back to the factory default settings, perform the
following steps:
1
Turn the master on/off key switch to the off position.
2
Press and hold the normal scrub 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 hourmeter/status display shows “donE”.
5
Release both switches.
6
The scrub modes and pressures have now been restored.
7
Turn the master on/off key switch to the off position.
SELECTION OF LOW VOLTAGE CUTOUT THRESHOLD:
FACTORY DEFAULT: STD
The 2800/BR700 is equipped with a low voltage cutout feature to prevent over-discharging the batteries. This feature will automatically
shut down the scrub system when the battery voltage falls to the selected threshold. The cutout level is adjustable. The standard setting
is 21 volts (1.75 volts per cell) and the so-called maintenance free setting is 22 volts (1.83 volts per cell). The standard setting should
be used unless the battery manufacturer specifies the higher cutout voltage.
It is important to note that some maintenance free
batteries (including some gelled electrolyte cells) are capable of being safely discharged down to 1.75 volts per cell.
To select between
the two types:
1
Turn the master on/off key switch to the off position.
2
Press and hold the scrub off switch.
3
While holding the scrub off switch turn the master on/off key switch to the on position.
4
Continue to hold the scrub off switch until the scrub off indicator turns red and the hourmeter/status display shows “Std” or “FrEE”.
5
Release the scrub off switch.
6
Pressing and releasing the scrub off switch will now select between the two options. For standard wet cell batteries select “Std”
and for maintenance free batteries select “FrEE”.
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.
