*Change of 4.5 Amps per PA unit. Values given are approximate.
Selection of Low Voltage Cutout Threshold:
FACTORY DEFAULT: STD
The 3800 / BR 1100 / 2042 and BR 1100C-XL 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 31.5 volts (1.75 volts per cell) and the so-called maintenance free setting is 33 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.
Recall Of Stored Error (Fault) Codes:
Whenever an electrical system fault is detected by the main control unit, one or more error codes are displayed and stored by the control unit. If
it is desired, the error code (if any) from the previous operation of the machine can be recalled for troubleshooting purposes. To recall the last stored
error codes 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 “Err *”. (* will be a letter indicating the revision level of the control
unit)
5
Release the horn switch.
6
If there were previously no error codes stored, the display will now show “nonE”. Go to step 12.
7
If error codes were stored, the display will now show the stored code(s) and the scrub off indicator will now be green.
8
To clear the stored codes press and release the scrub off switch.
9
The hourmeter/status display will now show “ErASE” and the heavy scrub indicator will be yellow.
10
To clear the stored codes, press and release the scrub off switch one more time. To return to the error code display without clearing the
codes press the heavy scrub switch.
11
If the scrub off switch was pressed the error codes will have been cleared and the display will show “nonE”.
12
To exit the error code recall mode, turn the master on/off key switch to the off position.
